Ingredients Breakdown
This cake combines a rich chocolate layer with a creamy peanut butter center. The key ingredients include:
- All-purpose flour – provides the base structure of the cake.
- Cocoa powder – adds depth and richness to the chocolate layer.
- Baking powder and baking soda – ensure the cake rises properly.
- Butter – gives the cake a tender crumb and rich flavor.
- Granulated and brown sugar – add sweetness and moisture.
- Eggs – act as a binding agent and provide structure.
- Milk – enhances the cake’s moistness and texture.
- Vanilla extract – adds depth of flavor to both cake and filling.
- Peanut butter – the star ingredient that gives the cake its signature flavor.
- Confectioners’ sugar – used in the peanut butter filling for a smooth, sweet layer.
- Chocolate ganache or frosting – crowns the cake with a glossy, rich finish.
Step-by-Step Recipe
- Preheat oven to 350°F (175°C) and prepare a 9-inch round or square cake pan by greasing and lining with parchment paper.
- Make the chocolate cake batter by creaming together butter and sugars, then adding eggs and milk. In a separate bowl, combine dry ingredients and gradually mix into the wet ingredients.
- Pour half the batter into the prepared pan and spread evenly.
- Prepare the peanut butter layer by mixing softened butter, peanut butter, and confectioners’ sugar until smooth. Drop spoonfuls over the cake batter and gently swirl with a knife.
- Add the remaining cake batter on top and smooth the surface.
- Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
- Let the cake cool completely before spreading a layer of chocolate ganache or frosting on top.
- Chill the cake for at least 30 minutes to allow flavors to meld and the topping to set.
Tips
- Use room temperature ingredients for a smoother batter and better blending.
- Don’t overmix the batter to avoid a dense texture.
- Swirl the peanut butter layer gently to create a marbled effect without fully blending.
- Chill the cake before slicing for cleaner cuts.
- Use natural peanut butter for a richer, less sweet flavor, or creamy for a smoother texture.
Variations and Customizations
- Layered version – Bake two cakes and sandwich them with peanut butter filling and chocolate ganache.
- Mini cupcakes – Make individual portions by baking in a muffin tin for 18–20 minutes.
- Chocolate drizzle – Add a decorative touch with melted chocolate drizzled over the top.
- Crunchy twist – Fold chopped peanuts into the peanut butter layer or sprinkle on top.
- Gluten-free option – Substitute all-purpose flour with a gluten-free flour blend.
- Dairy-free version – Use plant-based butter, almond milk, and vegan chocolate for a dairy-free alternative.
Health Considerations and Nutritional Value
This cake is rich in flavor but also in calories and sugar, so it’s best enjoyed in moderation. Each slice contains a significant amount of fats (from butter, peanut butter, and chocolate), carbohydrates (from sugar and flour), and some protein (from peanut butter and eggs). To make it healthier:
- Replace all-purpose flour with whole wheat flour for added fiber.
- Use natural peanut butter with no added oil or sugar.
- Opt for dark chocolate with a high cocoa content for antioxidants.
- Reduce sugar slightly in both cake and filling without compromising taste.
- Use a sugar substitute like erythritol or stevia for a lower-calorie version.
