Chocolate Sheet Cake With Peanut Butter Suede

This is my all-time favorite devil's food chocolate cake. Inspired by Anne Byrn the Cake Mix Doctor I have become quite a fan of jazzing up cake mix. I have a host of decadent frostings for all my cakes, but let me entice you here to try this deep rich chocolate cake adorned with what I call suede. If you love peanut butter and chocolate and who doesn't...you're going to love this super easy cake!

• Ready In: 55 mins
• Serves: 12

Ingredients

• Cake

• 1 (18 1/4ounce) package  pudding-enhanced  devil's food cake mix
• 3  tablespoons  unsweetened cocoa powder
• 1 1⁄3 cups buttermilk
• 1⁄2 cup  vegetable oil
• 3  large eggs
• 1  teaspoon pure vanilla extract

• Suede

• 1  cup creamy peanut butter
• 8  tablespoons butter, at room temperature
• 2  cups confectioners' sugar, sifted
• 4  tablespoons milk
• 2  teaspoons pure vanilla extract

Directions

1. PREHEAT oven to 350F. Mist a 13 x 9 inch baking pan with vegetable oil spray. Set aside.
2. COMBINE the cake mix, cocoa powder, buttermilk, vegetable oil, eggs, and vanilla in a large mixing bowl. Blend with an electric mixer until the batter is thick and smooth. Pour into prepared pan.
3. BAKE the cake until it springs back when lightly pressed with your finger, approximately 40 minutes. Cool cake in pan on wire rack for 30 minutes more and then slip the whole cake still in the pan into your freezer. (Frozen cakes are much easier to frost.) Now you can prepare the suede frosting.
4. COMBINE peanut butter and butter with your electric mixer on low speed until fluffy, stop the machine. Add the confectioners' sugar, milk, and the vanilla. Continue to blend on low until the sugar is well combined. Increase the speed and beat until frosting has a texture resembling suede. Use at once to frost cake.
5. STORE covered at room temperature for up to 3 days or in the fridge up to 1 week.
