  • Mix together the flour and the white sugar.

  • In a saucepan combine the Dr. Pepper, cocoa, and 1 cup of the butter or margarine, bring to a boil. Pour melted butter mixture over the flour and mix well. Stir in the beaten eggs, baking soda, vanilla, buttermilk and miniature marshmallows and mix well. Pour batter into the prepared pan.

  • Bake at 350 degrees F (175 degrees C) for 30 to 35 minutes. Remove from oven and spread peanut butter topping over warm cake. Place frosted cake under broiler, about 4 inches from the heat source. Broil for just a few seconds, or until topping starts to bubble. Do not scorch. Let cake cool at least 30 minutes before serving.

  • To Make Peanut Butter Topping: Cream together the remaining 6 tablespoons butter, the brown sugar, and the peanut butter. Add the milk and stir well. Mix in the nuts. Spread topping over still warm cake.

I made this as a Valentine treat for the husband. Yikes is it SWEET! I left out about 1/4 cup of the sugar and it is still super sweet. If I make it again I might leave out a little more maybe make it with 1.5 cups instead of the 2 called for...I mean you have DP marshmallows and that gooey sugary coating...I doubt the 1/2 cup of sugar will be missed!

The buttermilk in this recipe definitely made it moist. I was afraid it wouldn't be. The peanut butter topping was delicious! This would be a treat if you weren't counting calories! Totally would make again! Read More

I added 1 1/2 tsp. cinnamon to the cake batter as per a similar recipe. Tasted like a moist chocolate cake - could not taste the Dr. Pepper in it. I used a chocolate glaze since I cannot eat peanut butter. Good cake but don't expect any Dr. Pepper flavor. Read More

I'm always amazed by people who come on and change the recipe and then gripe that the recipe didn't taste like it was supposed to. I made this exactly the way it says and it was great. With 2 teen aged sons and all of their friends coming through the house it did not last 4 hours. I'm going to have to make 2 of them next time Read More

This was my first attempt at baking a cake from scratch and it was goooood. I used Denton Dr. Pepper and instead of marshmallows I used chocolate chips. I also used a chocolate icing instead of the peanut butter. I will make again. (And again!) Read More

Good. Doesn't taste like Dr. Pepper but is a good chocolate/peanut butter cake just the same. I followed the recipe exactly and it was very moist. However the next day the icing wasn't nearly as good. I will only make this again if I can serve it immediately after making it. Read More

Very easy to make but it is very sweet and rich. My 10yo son made this and entered it into our county fair. He won first place so we think it is a winning recipe. Next time we will either use less sugar or leave out the marshmallows. Read More
