Normally the cakes I post on my birthday are for the party I usually have, but this cake was actually made for one of my dear friend's birthday last week. You really just can't go wrong with that delectable combination of chocolate and peanut butter (last year's cake was certainly an indication) and the coffee in the cake batter makes the chocolate flavor stand out even more. This is super simple to make and thanks to help from my friend, Lawrence, it was easy to decorate. After frosting the outside of the cake with chocolate frosting, we surrounded the outside with leftover peanut butter frosting from the middle and topped it with mini peanut butter cups. Delicious. I'm celebrating my own birthday today with wonderful friends in Los Angeles. It is sure to be a super fun day and I feel so lucky to have such great friends near and far.

Chocolate Peanut Butter Cake
(Adapted from Tastes of Lizzy T's)
For the chocolate cake:
1 3/4 cup all-purpose flour
1 3/4 cup granulated sugar
3/4 cup unsweetened cocoa powder (not Dutch process)
1 teaspoon baking powder
2 teaspoons baking soda
1 teaspoon salt
1 cup buttermilk
1/2 cup canola oil
2 large eggs, at room temperature
1 teaspoon vanilla
1 cup coffee at room temperature
For the peanut butter frosting:
1/2 cup unsalted butter, at room temperature
1 cup creamy peanut butter
2 cups powdered sugar, sifted
2-3 tablespoons whole milk
For the chocolate frosting:
3 1/2 cups powdered sugar
1/2 cup cocoa powder
1 cup unsalted butter, at room temperature
1/2 teaspoon salt
2 teaspoons vanilla extract
1-3 tablespoons whole milk
To make the cake:
Preheat the oven to 350 degrees. Butter and flour two 9-inch cake pans.
In a large bowl, sift the flour, sugar, cocoa powder, baking powder, baking soda, and salt together. Stir to make sure they are fully combined.
In a stand mixer fitted with a paddle attachment, mix the buttermilk, oil, eggs, and vanilla together until combined. With the mixer on low, slowly add in the dry ingredients. Add the coffee and mix until everything is combined. The batter will be thin.
Pour the batter into the two prepared pans. Bake for 25-35 minutes or until a toothpick inserted in the center of each cake comes out clean. Cool the cakes in the pan for 5 minutes before turning out onto a cooling rack to cool completely before frosting.
To make the peanut butter frosting:
In a stand mixer fitted with the paddle attachment, cream together the peanut butter, butter and sugar until light and creamy, about 3 minutes. With the mixer turned down to low, add the powdered sugar. Add milk a little at a time until you reach your desired consistency.
To make the chocolate frosting:
In a large bowl sift together the powdered sugar and cocoa powder.
In a mixer fitted with the paddle attachment, cream the butter for 3 minutes or until light and fluffy. With the mixer turned down to low, slowly add the powdered sugar and cocoa powder mixture. Add the salt and vanilla extract and mix until well combined. Add the milk a little at a time until you reach the desired consistency.
