How to Make Peanut Butter Chocolate Layer Cake
Step 1: Prepare Your Oven and Pans
Preheat your oven to 350°F (175°C). Grease two 9-inch round baking pans with butter or cooking spray and dust them lightly with flour. This ensures your cake comes out easily after baking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine:
1 3/4 cups all-purpose flour
2 cups sugar
3/4 cup cocoa powder
2 1/4 tsp baking soda
1/2 tsp baking powder
1 tsp salt
Whisk these ingredients together until well combined.
Step 3: Combine Wet Ingredients
In a separate bowl, mix:
1 cup milk
1/2 cup vegetable oil
1 1/2 tsp vanilla extract
2 large eggs
Beat these together until smooth.
Step 4: Create the Batter
Add the wet ingredients to the dry mixture. Stir gently until just combined. Gradually add in:
1 cup hot water
Mix until you have a smooth batter.
Step 5: Bake the Cakes
Pour equal amounts of batter into each prepared pan. Bake for about 22 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely on a wire rack before frosting.

How to Serve Peanut Butter Chocolate Layer Cake
Serving your Peanut Butter Chocolate Layer Cake can elevate the experience and impress your guests. Here are some creative suggestions to make your dessert stand out.
With a Scoop of Ice Cream
- Vanilla ice cream pairs wonderfully with the rich flavors of peanut butter and chocolate, balancing the sweetness perfectly.
- Try chocolate or peanut butter ice cream for an indulgent twist.
Topped with Fresh Berries
- Fresh strawberries or raspberries add a refreshing contrast to the cake’s richness and enhance its visual appeal.
- A sprinkle of powdered sugar over the berries makes for a beautiful presentation.
Drizzled with Hot Fudge
- A warm fudge sauce adds an extra layer of deliciousness that complements the cake’s flavors.
- Serve it on the side for guests to pour themselves or drizzle over each slice.
Accompanied by Whipped Cream
- Light and fluffy whipped cream can cut through the density of the cake, providing a delightful texture contrast.
- Consider adding a hint of vanilla or almond extract to the whipped cream for added flavor.
Garnished with Chopped Nuts
- Chopped peanuts or walnuts not only enhance the visual appeal but also add a satisfying crunch to each bite.
- Toasting the nuts slightly before adding them gives an extra depth of flavor.
Served at Room Temperature
- Allowing the cake to come to room temperature before serving enhances the flavor and makes it easier to slice.
- This also ensures that all components, like frosting and fillings, have their best taste and texture.

How to Perfect Peanut Butter Chocolate Layer Cake
To achieve the best results with your Peanut Butter Chocolate Layer Cake, consider these helpful tips.
-
Use Room Temperature Ingredients: Ensure your eggs, milk, and butter are at room temperature. This helps create a smooth batter that rises well while baking.
-
Sift Your Dry Ingredients: Sifting flour, cocoa powder, and baking soda helps remove lumps and ensures even distribution in your batter.
-
Don’t Overmix: Mix just until combined when adding wet ingredients to dry. Overmixing can lead to a dense cake rather than a light and fluffy one.
-
Check for Doneness: Use a toothpick inserted into the center; if it comes out clean or with a few moist crumbs, your cake is done!
Best Side Dishes for Peanut Butter Chocolate Layer Cake

Common Mistakes to Avoid
When making a Peanut Butter Chocolate Layer Cake, it’s easy to encounter some common pitfalls. Here are a few mistakes to watch out for.
- Inaccurate measurements: Always measure your ingredients carefully. Using too much flour or sugar can lead to a dense cake.
- Not letting ingredients come to room temperature: Cold butter or eggs can affect how well the ingredients mix together. Make sure they are at room temperature for the best results.
- Underbaking or overbaking: Keep an eye on your cake as it bakes. A toothpick should come out clean when the cake is done; otherwise, you risk it being too dry or gooey.
- Skipping the frosting chill: If you don’t chill your peanut butter frosting, it may be too soft to spread nicely. Allow it to firm up slightly before using.
- Failing to split layers evenly: When cutting your cake into layers, use a serrated knife and take your time for even slices. This ensures each layer has the same height and looks beautiful.
