Chocolate Peanut Butter Earthquake Cake (1 hour 30 minutes)

Most of the time for this is the baking portion.  Made this for a desert the day before our Family Pizza and Movie Night.  Our weekly tradition has now grown to 3 families, which makes a Friday night fun for everyone.  This recipe will make a 9″ x 13″ pan.  I made each pan one at a time.




1 box of Chocolate Fudge cake mix, plus ingredients needed to prepare (eggs, oil, and water
1/2 cup Butter
8 oz Cream Cheese, softened
1/2 cup Creamy Peanut Butter
3 cups Powdered Sugar
1/2 cup Chocolate Chips
1 cup Miniature Chocolate Peanut Butter Cups, halved

Preheat oven to 350 degrees.



Prepare Chocolate Fudge cake mix according to package instructions.  If you have an electric mixer, place that on a slow mix and start cutting your Chocolate Peanut Butter Cups into halves.








After Peanut Butter Cups have been cut in half, place to the side for later.






Chocolate Fudge cake mix should be mixed up now.  Pour into a lightly greased 9″ x 13″ cake pan.  DO NOT BAKE!  Set aside for later.





Melt 1/2 cup of butter on stove top until bubbly.  Pour into mixing bowl and beat the butter and 8 oz of cream cheese until smooth.

Add 1/2 cup of peanut butter, beat until smooth.

Add one cup of powdered sugar at a time to bowl and beat until fully incorporated and mixture becomes light and fluffy.  Make sure you mix in each cup of powdered sugar before pouring in the next cup.

Scoop spoonfuls of the peanut butter mixture onto the chocolate cake batter.  Don’t worry about it being even, just glob that peanut butter all over the pan.

Then sprinkle with the 1/2 cup of chocolate chips and 1 cup of halved peanut butter cups.  Try to sprinkle evenly across the top of the cake mix.  Looks good already, but we’re not done.

Place pans in the oven for 45 – 55 minutes or until the center is only slightly jiggly.




TIME TIP: While this is going on, here are some things you can do around the house in the mean time.

  • Make your own bed (the one with 13 pillows and 4 sheets).
  • Switch over a load of laundry.
  • Fold a basket of laundry and put away.
  • Clean dishes and counter tops from making this desert.



Pull pans out of the oven and let sit for 15 – 20 minutes to cool down before serving if you want it warm.

You will notice that the cake has several cracks, like their was an earthquake and everything has been buried underneath the surface.






If you have any extra halves of Peanut Butter cups, go nuts and sprinkle the rest on top of the cake.  If you like peanut butter and chocolate as much as I do, you can never have too much in a recipe like this.



I placed mine in the fridge overnight for the Family Movie Night.  Slice up and serve.  Top with ice cream if desired.  Enjoy!
