Peanut Butter and Jam Cake: A Nostalgic Delight

There’s something inherently comforting about the combination of peanut butter and jam. It evokes memories of childhood lunches, carefree afternoons, and the simple joy of a perfectly balanced sweet and savory treat. My own earliest memory is carefully spreading each ingredient on slices of white bread, trying to get the perfect ratio of peanut butter to jelly. This cake takes that classic pairing and elevates it to a whole new level of indulgence, transforming familiar flavors into a sophisticated dessert that is sure to impress.

Recipe Overview

Total Time: 1 hour 25 minutes + cooling time
Servings: 12
Yield: 1 cake
Dietary Type: Not specified

Ingredients

2 1⁄4 cups cake flour, plus more for dusting pans
1 cup whole milk, at room temperature
6 large egg whites, at room temperature
2 teaspoons vanilla extract
1 3⁄4 cups sugar
4 teaspoons baking powder
1 teaspoon table salt
12 tablespoons unsalted butter, softened but still cool
16 tablespoons unsalted butter, softened
1 cup creamy peanut butter
3 tablespoons heavy cream
1 teaspoon vanilla extract
2 cups confectioners’ sugar (8 ounces)
1 3⁄4 cups seedless raspberry jam
1 cup dry roasted peanuts, chopped

Equipment Needed

Two 8-inch square baking pans
Parchment paper
Electric mixer (stand or handheld)
2-cup measuring cup
Rubber spatula
Wire racks
Large plate
Piping bag or small plastic sandwich bag

Instructions

Prepare the Oven and Pans: Adjust oven rack to middle position and heat oven to 350 degrees. Generously grease two 8-inch square baking pans and cover pan bottoms with squares of parchment paper. Grease and flour the parchment.
Combine Wet Ingredients: Mix milk, egg whites, and vanilla together in a 2-cup measuring cup.
Combine Dry Ingredients: Mix flour, sugar, baking powder, and salt together in the bowl of an electric mixer at low speed.
Incorporate Butter: Add butter (the 12 tablespoons, softened but still cool) and beat at low speed until mixture resembles moist crumbs, with no powdery streaks remaining.
Combine Wet and Dry Ingredients: Add all but 1/2 cup of the milk mixture to the crumb mixture and beat at medium speed (or high speed if using a handheld mixer) for 1 1/2 minutes. Add remaining 1/2 cup of milk mixture and beat 30 seconds more.
Scrape and Beat: Stop mixer and scrape sides of the bowl. Return mixer to medium (or high) speed and beat 20 seconds longer. This ensures all ingredients are properly combined.
Divide and Spread Batter: Divide batter evenly between the two prepared cake pans and using a rubber spatula, spread into an even layer.
Bake the Cakes: Arrange pans at least 3 inches from the oven walls and 3 inches apart. (If oven is small, place pans on upper middle and lower middle racks in staggered fashion to allow for air circulation.) Bake until a thin skewer or toothpick inserted in the center comes out clean, 21 to 25 minutes. Don’t overbake, as this will result in a dry cake.
Cool in Pans: Rest cakes in pans 10 minutes, then loosen from sides of pans with a knife. Invert onto large plate, then reinvert onto wire racks.
Cool Completely: Cool completely, about 1 1/2 hours. Ensure the cakes are completely cool before frosting, or the frosting will melt.
Prepare the Frosting: Using a stand mixer fitted with a whisk, whip butter (the 16 tablespoons, softened), peanut butter, cream, and vanilla on medium-high speed until combined, about 30 seconds.
Add Sugar Gradually: Reduce speed to medium-low and slowly add sugar until smooth, 1 to 2 minutes.
Whip Frosting Until Fluffy: Increase speed to medium-high and whip frosting until light and fluffy, about 5 minutes. This is crucial for a light and airy frosting.
Slice the Cakes: Slice each cake in half horizontally; this creates four thin layers.
Assemble the Cake: Spread 1/2 cup jam over each bottom half and replace the top half. You now have two reassembled cakes.
First Layer of Frosting: Place 1 reassembled cake on a cake plate, then spread 1 cup frosting in an even layer over the top.
Second Layer of Cake: Place the second reassembled cake on top of the frosting.
Frost the Cake: Spread the remaining frosting over the top and sides of the cake.
Add Peanuts: Press peanuts onto the sides of the cake.
Make Marbled Jam Topping: Heat remaining 1/4 cup jam in a bowl in the microwave until melted and smooth, about 20 seconds.
Pipe Jam: Transfer to a piping bag or small plastic sandwich bag with 1 corner cut off. Pipe jam in straight lines over the top of the cake and lightly drag a paring knife through the lines to create a marbled appearance.
Serve: Serve and enjoy!

Expert Tips & Tricks

Room Temperature Matters: Ensuring the milk and egg white mixture is at room temperature is vital for proper emulsification and a tender crumb. If you forget, gently warm the mixture as described in the original recipe.
Don’t Overmix: Overmixing the cake batter develops gluten, resulting in a tough cake. Mix until just combined.
Even Baking: For even baking, ensure your oven is properly preheated and the cake pans are evenly spaced.
Frosting Consistency: If your frosting seems too stiff, add a tiny bit more heavy cream, a teaspoon at a time, until you reach the desired consistency. If it’s too loose, add a tablespoon of powdered sugar at a time.
Peanut Butter Choice: Use a creamy peanut butter without stabilizers for the best texture. Natural peanut butter can sometimes separate and affect the frosting. If you do use natural peanut butter, make sure to stir it very well before measuring.

Serving & Storage Suggestions

This Peanut Butter and Jam Cake is best served at room temperature. The flavors are most pronounced and the frosting is at its ideal texture. To store, keep the cake in an airtight container in the refrigerator. It will keep for up to 3 days. Before serving, allow the cake to sit at room temperature for about 30 minutes to soften the frosting.

While freezing is not ideal due to the frosting’s texture, you can freeze individual slices wrapped tightly in plastic wrap and then in foil for up to a month. Thaw in the refrigerator overnight.

FAQs (Frequently Asked Questions)

Q: Can I make this cake ahead of time?
A: Yes, the cake layers can be baked a day in advance, wrapped tightly in plastic wrap, and stored at room temperature. The frosting can also be made a day ahead and stored in the refrigerator. Let it come to room temperature and rewhip before using.

Q: Why is it important for the milk and egg whites to be at room temperature?
A: Room temperature ingredients emulsify better, creating a smoother batter and a more tender cake crumb.

Q: Can I use natural peanut butter for the frosting?
A: Yes, but make sure to stir it very well before measuring, as the oil tends to separate. You may need to adjust the amount of heavy cream to achieve the desired consistency.

Q: How do I prevent the cake from sticking to the pan, even with parchment paper?
A: Generously grease the pans with shortening or butter and then dust with flour, tapping out the excess. This, combined with the parchment paper, will ensure easy release.

Q: What if my frosting is too sweet?
A: Reduce the amount of confectioners’ sugar slightly, or add a pinch of salt to balance the sweetness.
