Lisa’s Bday Chocolate Peanut Butteryness Layer Cake

December 28, 2014

Lisa’s birthday came around this December and her request this year was something with peanut butter. I love getting a specific ingredient request, but still having the flexibility to twist it however I like. This was a new one for me. I haven’t done hardly any baking with peanut butter, but I do love it. I did some recipe searching and was looking through one of my bookmarked bloggers, browneyedbaker and found this recipe and knew instantly this was the one I had to try.

I had just made Bill’s bday cake which was a very delicious standard chocolate cake. The cake part was really very moist and I contemplated using that cake recipe again, but decided to stay with the original one with this recipe. They aren’t far off from each other, but this one called for Dutch process coco instead of natural processed coco and because of that I think it ended up less fluffy and more dense and actually more to my liking, but both are great.

And as for the rest and fully assembled cake, it was AMAZING! The peanut butter frosting was a great mix of sweet and salty and the ganache made it look pretty professional. It was definitely one of my favorite cakes I’ve made.

One of my prettiest cakes!

PB Cake Half




1. Preheat oven to 350 degrees F. Grease three 8 or 9-inch round cake pans, line the bottoms with rounds of parchment paper, grease the parchment, then flour the insides of the pans, tapping out excess; set aside.

2. In the bowl with an electric mixer, sift together the flour, sugar, cocoa powder, baking soda, baking powder and salt.

3. In a medium bowl, whisk together the eggs, buttermilk, coffee, oil and vanilla.

4. Add the wet ingredients to the dry ingredients and mix for 2 minutes on medium speed. Scrape the sides and bottom of the bowl and mix for an additional 20 seconds (the batter will be very thin).

5. Divide the batter evenly among prepared pans. Bake for 20 minutes and rotate the pans in the oven. Continue to bake until a toothpick inserted into the center of one of the cakes comes out almost clean (with a few moist crumbs), about 7-12 more minutes. Cool the cakes (in the pans) on wire racks for 20 minutes, then carefully turn them out onto cooling racks to cool completely.

Peanut Butter Frosting

6. Place the powdered sugar, peanut butter, butter (make sure it’s room temperature otherwise you will have butter chunks), vanilla and salt in the bowl of an electric mixer with a paddle attachment. Mix on medium-low speed until creamy, scraping down the bowl with a rubber spatula as needed. Add the heavy cream and beat on high speed until the mixture is light and smooth (do not overbeat).

Assemble the Cake

7. If your cakes baked up uneven or have domed on top, level off the tops. Place one cake layer on a serving plate. Cover with 1 cup of the peanut butter frosting and sprinkle 10 of the chopped peanut butter cups over the frosting.

8. Top with a second cake layer and cover with another 1 cup of the peanut butter frosting, and top with another 10 chopped peanut butter cups.

9. Place the final cake layer on top face-down. Frost the cake with the remaining peanut butter frosting, finishing it as smoothly as possible. Refrigerate the cake for at least 1 hour, until the frosting is set.

Chocolate Ganache

10. While the cake chills, make the chocolate ganache. Place the chocolate in a 4-cup measuring cup; set aside.

11. Place the cream in a small saucepan over medium heat and warm until it just comes to a boil. Pour the cream over the chopped chocolate and let sit for 2 minutes. Begin whisking the mixture in the center, gradually working your way outward until the ganache is completely smooth. Set aside to cool, whisking occasionally, until it has thickened slightly, yet still a pourable consistency.

Garnish the Cake

12. If the ganache was mixed in a bowl, transfer it to a 2-cup measuring cup. Slowly pour the chocolate ganache into the center of the cake, letting it push itself outward and flow over the sides of the cake. Top with the remaining 10 chopped peanut butter cups.

13. Refrigerate the cake for at least 30 minutes, giving the ganache a chance to set up. Keep the cake refrigerated, removing it from the refrigerator about 20 minutes prior to serving.
