  • In a small bowl, stir together the cocoa, confectioners' sugar, butter and 2 tablespoons hot water until smooth and set aside.

  • In microwavable bowl, place peanut butter chips and shortening. Microwave on high for 1 minute, or until chips are melted and smooth when stirred.

  • In large bowl, combine cake mix, brown sugar, 1-1/4 cups water, eggs and reserved melted peanut butter mixture; beat on low speed of electric mixer until moistened. Increase speed to medium, beat 2 minutes until smooth. Remove 1-1/2 cups of the batter and add it to the reserved cocoa mixture; blend well.

  • Pour the peanut butter flavored batter into the prepared pan. Drop spoonfuls of the chocolate batter on top. Swirl with a knife or spatula for a marbled effect.

  • Bake at 350 degree F (175 degrees C) for 40 to 45 minutes or until a wooden toothpick inserted in the center comes out clean. Cool and frost as desired.

This cake was very dry. I may have done something wrong because other reviewers really loved it. I didn't like it at all but some other people at the picnic said it was pretty good. Read More

This cake is SO GOOD! I made 2 round layers with peanut butter frosting and mini chocolate chips on top and in between the layers. For the frosting I used pre-made cream cheese frosting mixed with natural peanut butter. I also used natural peanut butter in the recipe instead of peanut butter chips. Everyone at my husbands birthday party said it tasted just like a Reeses peanut butter cup - yum! Read More

I made this for my Dad's birthday and it was a hit! He requested a peanut butter chocolate cake...and this is what I thought would work. It's definitly peanut butter chocolatey..and VERY MOIST! One suggestion...since it doesn't call for a certain frosting...I would recommend adding butter cream frosting to another peanutbutter-chip-and-shortning-mixture. Then after you frost it..sprinkle chocolate chips and your leftover peanut butter chips on top. That's what I did. Enjoy! Read More

Excellent. I made this for my son's birthday, at his request. The cake is moist and dense - just the way we like it. I baked it in a bundt pan for 1 hour, frosted with pb frosting and decorated with mini choc chips and chopped peanut butter cups. Thanks for the recipe - I see a repeat in our future. ;) Read More

This cake is wonderful! I substituted 1 cup creamy peanut butter for the pb chips and shortening. I baked it in a bundt pan at 350 degrees for one hour and served it with the Fluffy Peanut Butter Frosting recipe from this site. Moist and delicious! Read More

Hmm.. this was a keeper! My hubby couldn't find just peanut butter chips so he got the Toll House chocolate and peanutbutter chips. This was fabulous. Oh be careful b/c water is not listed on the ingredients but is listed in the recipe. I had to add water after dividing the chocolate and peanutbutter parts. Read More

Oh my goodness. If you are a peanut butter and chocolate lover this is the cake for you. I followed the recipe with a couple of changes based on previous reviews. I used a cup of peanut butter for the chips and added a cup of semisweet chocolate chips to batter. I cooked it in a heavy bundt pan for 50 mins. Cake is so moist. I used the satiny chocolate glaze to which I added 1/4 cup peanut butter. It is pretty rich with these changes but oh so good. Read More
