There is something almost magical about the combination of peanut butter and jelly. It lives in our memory as something humble and everyday, folded into wax paper and tucked into a lunchbox. But take those same flavors and layer them into a tall, elegant cake and something wonderful happens. The peanut butter sponge is rich and nutty without being heavy, the raspberry jam bursts with a bright tartness that cuts right through the sweetness, and the whipped peanut butter frosting pulls it all together in the most satisfying way. This is comfort food dressed up for a celebration.

What sets this cake apart is the technique used for the sponge layers. By creaming the peanut butter with the butter before adding sugar, you build a deeper, more complex peanut flavor into the crumb itself rather than relying only on the frosting to carry it. A touch of brown sugar alongside the white sugar adds a subtle molasses warmth that pairs beautifully with the jam. The frosting is whipped for several minutes longer than you might expect, which gives it an almost mousse-like lightness so it never feels heavy or cloying on the palate.

This cake sits confidently in the medium difficulty range. If you have made a layer cake before, this will feel very familiar. If this is your first time, the steps are clearly laid out and forgiving. It is a perfect weekend bake for birthdays, summer gatherings, or honestly any Tuesday when you need something truly delicious waiting on the counter.

Ingredient Substitutions

smooth commercial peanut butter

Almond butter or sunflower seed butter in equal amounts for a nut-free or peanut-free version. The flavor profile changes but the texture of the batter and frosting will be very similar.
Natural peanut butter can be used but the batter may be slightly oilier and the frosting less stable. Stir it very well before measuring and chill the frosted cake before serving.

raspberry jam

Strawberry jam, blackberry jam, or grape jelly all work beautifully and stay true to the PB&J spirit.
Fresh strawberry or raspberry compote made by simmering 250g berries with 50g sugar until thickened. Let it cool completely before using.

sour cream

Full-fat plain Greek yogurt in an equal amount. The texture and tang are nearly identical.
Full-fat creme fraiche in an equal amount for a slightly richer result.

whole milk

Oat milk or unsweetened almond milk in an equal amount. The cake will be very slightly less rich but still delicious.
Buttermilk in an equal amount. Reduce baking powder by 1/4 tsp and increase baking soda by 1/4 tsp to compensate for the added acidity.

eggs

For each egg, use 1 tbsp ground flaxseed mixed with 3 tbsp warm water, rested for 5 minutes. The cake will be slightly denser and the crumb a little more tender. This works for all 3 eggs in this recipe.

heavy cream (in frosting)

Whole milk can replace heavy cream in the frosting, added one tablespoon at a time. The frosting will be slightly less rich and may need to be chilled before spreading.
Canned full-fat coconut cream works well for a dairy-free frosting and adds a subtle coconut note.

Prep: 40 minutes
Bake: 28 to 32 minutes at 350°F (175°C)
Total: 2 hours (including cooling)

Preheat your oven to 350°F (175°C). Grease three 8-inch round cake pans, line the bottoms with parchment paper circles, then grease the parchment and dust each pan lightly with flour, tapping out any excess.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside. In a small bowl or measuring jug, whisk together the whole milk and sour cream until smooth. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, beat the room-temperature butter and peanut butter together on medium speed for 2 full minutes until the mixture is pale and very smooth. Add the granulated sugar and brown sugar and continue beating for another 3 minutes, scraping down the sides of the bowl as needed, until the mixture is light and fluffy.
Add the eggs one at a time, beating for 30 seconds after each addition. Scrape the bowl well. Add the vanilla extract and beat briefly to combine.
With the mixer on low speed, add the flour mixture in three additions, alternating with the milk and sour cream mixture in two additions. Begin and end with the flour. Mix only until just combined after each addition. A few small streaks of flour are fine. Finish folding by hand with a spatula to avoid overmixing.
Divide the batter evenly among the three prepared pans. A kitchen scale makes this easy. Smooth the tops gently with an offset spatula. Bake for 28 to 32 minutes, until the tops are golden, the edges pull slightly from the pan, and a toothpick inserted in the center comes out with just a few moist crumbs.
Let the cakes cool in their pans on a wire rack for 15 minutes, then run a thin knife around the edges and turn them out onto the rack. Peel off the parchment and allow the layers to cool completely, at least 1 hour, before assembling.
To make the frosting, beat the room-temperature butter and peanut butter together in a stand mixer on medium-high speed for 3 full minutes until very light and creamy. Add the sifted powdered sugar one cup at a time, beating on low after each addition. Add the vanilla, a pinch of salt, and the heavy cream. Increase speed to medium-high and beat for an additional 3 minutes until the frosting is noticeably lighter, fluffy, and spreadable. If it seems too thick, add cream one teaspoon at a time.
To assemble, place one cake layer on a serving plate or cake board. Spread half of the raspberry jam in an even layer, leaving a 1/4-inch border around the edge. Pipe or spoon a ring of peanut butter frosting around the edge of the jam to act as a dam and keep the jam from squeezing out. Place the second cake layer on top, press very gently, and repeat with the remaining jam and another frosting dam. Place the final cake layer on top, bottom-side up for a flat surface. Apply a thin crumb coat of frosting all over the cake, then refrigerate for 20 minutes. Finish with a generous layer of frosting on the top and sides. Garnish with chopped roasted peanuts and a drizzle of warmed raspberry jam if desired.

This method gives you all the flavor of the layer cake in a much more relaxed, beginner-friendly format. Great for casual gatherings, potlucks, or school events where slicing a tall layer cake is not practical.

Preheat your oven to 350°F (175°C). Grease a 9×13-inch metal baking pan and line with parchment paper, leaving an overhang on the long sides for easy lifting.
Prepare the cake batter exactly as described in the oven method, steps 2 through 5. Pour all of the batter into the prepared pan and spread it level with an offset spatula.
Spoon the raspberry jam over the top of the batter in small dollops spaced across the entire surface. Use a butter knife or skewer to swirl the jam gently into the top of the batter, creating a marbled look. Do not mix it in completely.
Bake for 30 to 35 minutes, until the cake is set across the whole surface, the edges are pulling from the pan, and a toothpick inserted in the center comes out with just a few moist crumbs. Allow to cool completely in the pan on a wire rack.
Prepare the peanut butter frosting as directed in step 8 of the oven method. Spread the frosting generously over the top of the cooled cake in thick swoops. Scatter chopped roasted peanuts over the top and drizzle with an additional tablespoon of warmed jam for a beautiful finish. Slice directly from the pan.

The same batter makes approximately 24 cupcakes. A hidden jam filling inside each cupcake makes these extra fun and gives you that classic PB&J surprise in every bite.

Preheat your oven to 350°F (175°C). Line two standard 12-cup muffin pans with paper liners.
Prepare the cake batter exactly as described in the oven method, steps 2 through 5. Fill each cupcake liner two-thirds full with batter. Do not overfill.
Bake for 18 to 22 minutes, until the tops are domed and golden and a toothpick inserted in the center comes out clean or with a couple of moist crumbs. Do not open the oven before 18 minutes. Let the cupcakes cool in the pan for 5 minutes, then transfer to a wire rack and cool completely.
Once cooled, use a small paring knife or a cupcake corer to cut a shallow cone from the center of each cupcake, about 3/4 inch deep. Fill each cavity with approximately 1 teaspoon of raspberry jam. Replace the top of the cut-out piece over the jam, pressing it down gently so the surface is flat.
Prepare the peanut butter frosting as directed in the oven method. Transfer to a piping bag fitted with a large star tip and pipe a swirl of frosting on each cupcake. Finish with a small dollop of jam on top and a sprinkle of chopped salted peanuts.

Why This Recipe Works

Commercial peanut butter, such as Jif or Skippy, is specifically called for here because it contains stabilizers that keep the oils from separating. This matters enormously in both the cake and the frosting. Natural peanut butter is mostly oil and ground peanuts with nothing to hold them together, which can make the batter greasy and the frosting unstable or grainy at room temperature. The stabilized variety behaves more like a fat with consistent texture, giving you a reliable result every time.

The combination of whole milk and sour cream in the batter is doing important work. The fat in the sour cream adds richness and tenderness to the crumb by coating the gluten strands before they fully develop, while the mild acidity in the sour cream reacts with the baking soda to produce a fine, even rise. This dual-leavening approach, using both baking powder for a steady lift and baking soda to neutralize the acidity and add browning, is why the layers bake up tall and golden without doming too aggressively in the center.

The frosting dam technique during assembly is the single most important tip for a clean, professional-looking slice. Raspberry jam is fluid enough under pressure to push outward and split your layers apart if it has nothing to hold it in. By piping a ring of the thick peanut butter frosting around the perimeter of each jam layer before stacking, you create a physical barrier that keeps the jam exactly where you want it. If your cake is leaning or the layers are sliding during assembly, chill the crumb-coated cake for at least 20 minutes before applying the final coat of frosting. Cold cake is much more forgiving to work with.

Baker’s Tips

Room temperature ingredients are non-negotiable here. Cold eggs or cold milk added to the creamed butter and peanut butter will cause the mixture to curdle or look curdled, which affects the final texture. Take everything out of the refrigerator at least 45 minutes before you start.
Use a kitchen scale to divide batter evenly among the three pans. Equal layers mean even baking times and a cake that sits level without trimming.
Do not use natural or drippy peanut butter in this recipe. The separated oil will make the batter greasy and the frosting soft and unstable. Stick with commercial creamy peanut butter for best results.
If your jam is thick and stiff, warm it gently in a small saucepan or in the microwave for 10 to 15 seconds and stir until just fluid. It will spread much more easily and evenly without tearing the cake layer.
For the cleanest cake slices, dip your knife in hot water and wipe it dry between each cut. The warmth glides through the frosting without dragging.
The frosting pipe dam is your best friend for a neat assembly. Fit a piping bag with a plain round tip and pipe a thick ring of frosting just inside the edge of each cake layer before spooning in the jam. This prevents the jam from squeezing out the sides when the next layer is pressed on top.

Variations

Strawberry and honey version: Swap the raspberry jam for strawberry jam and add 2 tablespoons of honey to the cake batter along with the sugars for a floral sweetness.
Chocolate PB&J: Replace 30g of flour with Dutch-process cocoa powder and add 1 teaspoon of espresso powder to the dry ingredients for a chocolate-peanut butter base with the jam filling.
Spicy peanut butter: Add 1/4 teaspoon of cayenne pepper to the frosting for a subtle heat that plays beautifully against the sweet jam.
Pretzel crunch topping: Scatter crushed salted pretzels over the frosted cake just before serving for a salty, crunchy finish that takes this over the top.

Troubleshooting & FAQ

My cake layers domed in the center and are uneven. How do I fix this?

Doming usually happens when the outer edges of the cake set and cook faster than the center, pushing the batter upward. This is very common and completely fixable. Once the layers are fully cooled, use a long serrated knife to level each layer by slicing off the dome in one slow, steady sawing motion. Alternatively, wrap wet cake strips around the outside of your pans before baking. These insulating strips slow down the edge baking time, encouraging the whole layer to rise evenly.

My peanut butter frosting is too stiff and difficult to spread. What went wrong?

This usually means the butter or peanut butter was slightly too cold, or too much powdered sugar was added too quickly. First, make sure your butter is genuinely at room temperature. If the frosting is already made, beat it on medium-high speed for an additional 2 minutes and add heavy cream one teaspoon at a time until it loosens to a spreadable consistency. Never add milk all at once or you risk making it too thin.

The jam is oozing out from between my cake layers. How do I prevent this?

The jam dam technique is the fix here. Before spreading the jam onto a cake layer, pipe or spread a thick ring of peanut butter frosting around the outer edge of that layer first, like a fence. Then spoon the jam inside the ring. The frosting ring contains the jam under the weight of the next layer. Also make sure your jam is not too warm or fluid when you apply it. Let it cool to room temperature after any warming.

My cake has a dense, gummy texture. What happened?

A dense or gummy crumb usually comes from overmixing the batter once the flour was added, or from opening the oven door too early. Overmixing develops too much gluten, making the cake tough. Mix only until just combined after adding the flour and finish with a few gentle folds by hand. Also check that your baking powder and baking soda are fresh. Test baking powder by dropping a teaspoon into hot water. It should bubble vigorously. If it barely fizzes, it needs to be replaced.

Can I make this as a two-layer cake instead of three layers?

Absolutely. Divide the batter between two 8-inch or 9-inch round pans and bake for 32 to 38 minutes, checking from 32 minutes onward. The layers will be thicker so they need more time in the oven. All other assembly steps remain the same, just with one layer of jam filling instead of two. You may have a little extra frosting, which is never a bad thing.

Storage & Make-Ahead

Storage: Store the assembled cake under a cake dome or wrapped loosely at room temperature for up to 2 days, or refrigerate for up to 5 days. Bring slices to room temperature for 20 to 30 minutes before serving for the best texture. Individual slices can be frozen, well wrapped, for up to 2 months.
Make-Ahead: The cake layers can be baked, cooled completely, wrapped tightly in plastic wrap, and stored at room temperature for up to 2 days, or frozen for up to 3 months. Thaw overnight in the refrigerator before assembling. The peanut butter frosting can be made up to 3 days ahead, stored in an airtight container in the refrigerator, and re-whipped with a mixer for 1 to 2 minutes before using. The fully assembled cake can be made one day ahead and refrigerated.
