How to Make Chocolate Peanut Butter Layer Cake with Chocolate Ganache
Creating this Chocolate Peanut Butter Layer Cake with Chocolate Ganache is a delightful journey.
Follow these simple steps, and you’ll have a show-stopping dessert that will impress everyone.
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C).
While it warms up, grease and flour two 9-inch round cake pans.
This ensures your cakes will slide out easily once baked.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt.
Whisk them together until well blended.
This step is crucial for an even distribution of flavors.
Step 3: Combine Wet Ingredients
Now, add the large eggs, whole milk, vegetable oil, and vanilla extract to the dry mix.
Beat everything together on medium speed for about 2 minutes.
You want a smooth batter, so don’t rush this part!
Step 4: Add Boiling Water
Here’s where the magic happens!
Carefully stir in the boiling water.
This step makes the batter thin but helps bloom the cocoa, intensifying that rich chocolate flavor.
Step 5: Bake the Cakes
Pour the batter evenly into your prepared cake pans.
Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
The aroma wafting through your kitchen will be heavenly!
Step 6: Cool the Cakes
Once baked, let the cakes cool in the pans for about 10 minutes.
Then, gently remove them from the pans and transfer to wire racks to cool completely.
This cooling time is essential for frosting later.
Step 7: Make the Peanut Butter Frosting
In a mixing bowl, beat the softened unsalted butter until creamy.
Gradually add the powdered sugar and creamy peanut butter, mixing until smooth.
Finally, add the heavy cream and vanilla extract, beating until fluffy.
This frosting is the heart of your cake!
Step 8: Assemble the Cake
Once the cakes are completely cool, place one layer on a serving plate.
Spread a generous amount of peanut butter frosting on top.
Then, place the second layer on top and frost the top and sides with the remaining frosting.
Make it as smooth or rustic as you like!
Step 9: Prepare the Chocolate Ganache
To make the ganache, heat the heavy cream in a small saucepan until it’s just simmering.
Pour the hot cream over the semi-sweet chocolate chips in a bowl and let it sit for 2 minutes.
Stir until smooth and glossy.
This ganache will be the crowning glory of your cake!
Step 10: Finish the Cake
Pour the ganache over the top of the frosted cake, allowing it to drip down the sides.
Let it set for about 30 minutes before slicing.
This final touch transforms your cake into a decadent masterpiece!

Tips for Success
- Measure your ingredients accurately for the best results.
- Use room temperature eggs and milk for a smoother batter.
- Don’t skip the cooling time; it helps the frosting set better.
- For a richer flavor, add a teaspoon of instant coffee to the boiling water.

Equipment Needed

Variations
- Gluten-Free Option: Substitute all-purpose flour with a gluten-free flour blend for a delicious gluten-free cake.
- Nut-Free Version: Use sunbutter or almond butter instead of peanut butter for a nut-free alternative.
- Vegan Twist: Replace eggs with flax eggs and use plant-based milk and butter for a vegan-friendly cake.
- Chocolate Lovers Delight: Add chocolate chips to the batter for an extra chocolatey experience.
- Fruit Infusion: Layer in fresh raspberries or strawberries between the cake layers for a fruity contrast.
Serving Suggestions
- Pair with a scoop of vanilla ice cream for a delightful contrast.
