Chocolate Peanut Butter Marble Cake

So good and SO easy to make!  Very moist!  Crowd pleaser–indeed!


1/4 cup cocoa powder
2 Tablespoons Powered Sugar
2 Tablespoons Butter, Softened
2 Tablespoons HOT water
1 cup Peanut Butter
1 Tablespoon Shortening
1 (18.25 ounce) package white cake mix
1/2 cup packed brown sugar
1 1/4 cups water
3 eggs


  1. Preheat oven to 350 degrees .
  2. Spray 2  round cake pans with a non-stick cooking spray, dust with flour and set aside. **See note**
  3. In a small bowl, stir together the cocoa, powdered sugar, butter and 2 tablespoons hot water until smooth-set aside.
  4.  In a microwavable bowl melt the shortening with the peanut butter until smooth and blended (should take about a minute-I heat it at 15 /20 second intervals)
  5. In a Large Bowl combine cake mix, brown sugar 1-1/4 cups water, eggs and the melted peanut butter.  Beat on low-speed until moistened.  In crease speed to medium and beat until smooth.  Approx. 2 minutes.
  6. Remove 1-1/2 cups batter and add it to the cocoa mixture until blended and smooth.
  7.  Pour the peanut butter batter into prepared pans (dividing it up by half).
  8. Drop spoonfuls of the cocoa batter on top.  Swirl with a toothpick, spatula…etc to achieve the marbled effect.
  9. Bake at 350 degrees for approx. 28 to 30 minutes or until wooden toothpick inserted in the center comes out clean.
  10.  Cool and Frost!

Notes:  You can use ANY size of baking pan for this cake.  Just follow the times on the back of the package.  For the frosting…you can use anything you like.  I made a Peanut Butter frosting.  My son requested it (for his birthday).  This cake tasted JUST like a Reese’s Peanut Butter Cup!
