Peanut Butter Chocolate Poke Cake

"When my family is planning a get-together, I can count on three or four people asking if I'm bringing this chocolate peanut butter poke cake. If you don't have a chocolate cake mix, use a white or yellow one and stir in 3 tablespoons of baking cocoa." —Fay Moreland, Wichita Falls, Texas
