Can I use natural peanut butter in a cake?

It is highly recommended to avoid natural peanut butter that separates, as the excess oil sitting at the top can disrupt the balance of fats in the batter. This can lead to cake layers that are overly greasy, dense, or prone to sinking in the middle. Instead, choose a creamy, processed peanut butter that remains stable and smooth at room temperature.

Should a peanut butter cake have peanut butter or chocolate frosting?

Both options are wonderful, but they offer very different experiences. A peanut butter frosting creates a rich, deeply cohesive flavor profile that highlights the roasted nuttiness throughout the entire dessert. A chocolate frosting, on the other hand, provides a classic, sweet contrast that cuts through the saltiness of the peanut butter beautifully.

Why is my peanut butter cake dry?

A dry cake is usually the result of overbaking or adding too much flour to the batter. Always check your cakes a few minutes before the baking time is up, and use a digital kitchen scale to measure your flour accurately. Overmixing the batter after adding the dry ingredients can also develop too much gluten, making the crumb tough and dry.

How do you prevent peanut butter frosting from becoming too stiff?

To keep your frosting silky and spreadable, ensure both your butter and heavy cream are at true room temperature before mixing. If the frosting becomes too stiff or develops air bubbles, gently warm it in the microwave in five-second bursts and re-whip it. Adding a tablespoon of heavy cream can also help soften the consistency.

How do you decorate a two-layer peanut butter cake?

Keep the decoration simple and rustic to reflect the warm, homemade nature of the recipe. Spread a thick, smooth layer of frosting between and around the layers, then use a spatula to create elegant swirls on the top and sides. Finish with a generous scatter of finely chopped roasted peanuts or a gentle drizzle of melted peanut butter.

Can I make this cake ahead of time and freeze the layers?

Yes, you can bake the cake layers ahead of time, let them cool completely, and wrap them tightly in plastic wrap and aluminum foil before freezing. They can be frozen for up to three months and thawed in the refrigerator overnight before assembling. Frosting the cake while the layers are slightly cold actually helps reduce crumbs and makes spreading easier.

How should I store leftover peanut butter cake?

Store any leftover cake in an airtight container or under a cake dome at room temperature for up to three days. If your kitchen is very warm, you can store it in the refrigerator, but be sure to bring slices to room temperature before serving. This allows the fats in the cake and frosting to soften, restoring its signature melting texture.

Instructions

Prep the oven and pans: Preheat oven to 180°C (350°F) or 160°C (320°F) for convection/fan ovens. Grease and line two 8-inch cake tins with parchment paper.
Sift dry ingredients: Sift together the flour, cornstarch, baking soda, baking powder, and salt into a bowl. Whisk until fully combined and set aside.
Cream fats and sugars: In a large bowl, combine butter, vegetable oil, white sugar, soft brown sugar, and peanut butter. Beat with an electric mixer on medium speed for 3 minutes until light and creamy.
Add eggs: Add the eggs one at a time on low speed, mixing for 10-15 seconds between each addition to maintain the emulsion.
Combine wet ingredients: Mix in the vanilla and buttermilk on medium speed until you have a smooth, creamy liquid batter.
Fold dry ingredients: Add the pre-sifted dry ingredients. Fold gently by hand using a spatula until just combined and no flour streaks remain.
Bake the layers: Divide batter evenly between the two tins. Tap lightly on the counter to release air bubbles, then bake for 30-35 minutes until a toothpick comes out clean.
Cool completely: Let cakes cool in their tins for 15-20 minutes, then turn out onto a wire rack to cool completely before frosting.
Whip the frosting: Combine all frosting ingredients in a bowl. Mix on low for 1 minute, then turn up to medium-high and whip for a full 10 minutes until silky smooth.
Assemble: Place the first cooled layer on a plate, spread 1 cup of frosting on top, stack the second layer, and frost the top and sides of the cake.

Notes

Room Temperature Ingredients: Always ensure buttermilk, eggs, and butter are at room temperature to prevent the batter from curdling.
Measuring Flour: Use a kitchen scale for best accuracy. If using cups, spoon and level to prevent adding too much flour and drying out the cake.
Peanut Butter Choice: Use a commercial, processed creamy peanut butter. Natural peanut butters that separate will add too much liquid fat and ruin the cake’s structure.
Fixing Stiff Frosting: If your frosting feels stiff, warm it in the microwave in 5-second bursts and re-whip to restore its silky texture.
