Chocolate Peanut Butter Cupcakes

After seeing Joe’s banana cake, topped with a gorgeous looking peanut butter frosting, I knew that I had to find something to put it on. And very few combinations work as well as peanut butter and chocolate.

I went with a batch of moist chocolate cupcakes. They are quite easy to put together and are really delicious. The cake is cark, moist and tender, with a great chocolate flavor. Though I usually like to use buttermilk in chocolate cakes, this recipe uses plain milk. The lowfat variety is fine, but make sure to warm it up slightly, as that will help the flavor of the cocoa really come out.

Peanut butter wasn’t overwhelming in the frosting, making the inside of your mouth sticky. Instead, it was plesantly sweet and smooth, a great topper for the cupcakes. I liked a thin coating of frosting for these, not only because I would have had to double the frosting recipe for a thicker layer, but because it would have been too sweet otherwise. I added 1/4 cup more confectioners sugar to the original recipe to make it a bit stiffer.

Chocolate Cupcakes
1 ½ cups all purpose flour
¾ cup cocoa powder
¼ tsp baking soda
2 tsp baking powder
¼ tsp salt
¼ cup butter, very soft
1 cup sugar
½ cup brown sugar
2 eggs, room temperature
1 tsp vanilla extract
1 cup milk, warm

Preheat oven to 350F. Line 24 muffin cups with paper liners.
In a medium bowl, sift together flour, cocoa powder, baking soda, baking powder and salt.
In a large bowl, cream together butter and in eggs one at a time. Add vanilla.
Add flour and milk, alternating in 3 additions, ending with flour.
Evenly distribute into prepared muffin tins.
Bake at 350F for 15-17 minutes, until a tester comes out clean and the cake springs back when lightly pressed.
Cool completely on a wire rack.

Makes 24.

    Those look fantastic!

  10. Those look great, I like the idea and the look of the frosting. Did you use a pastry bag and tip?

  11. biscuit girl – I highly recommend it!

    bokbaksa – They’re a great choice to bring to a party, and sure to be a hit.

    Joe – I think you’ve done plenty of delicious chocolate/peanut butter combos. And peanut butter/banana is a close, close second.

    Cindy – These are a great choice with tea, possibly even better with coffee or milk, though.

    Cookbook Junkie – Thanks!

    Baking Soda – I used a small offset spatula, but a blunt knife will work fine; I wanted the icing to be smooth, not as defined as a pastry bag would have made it.

  12. those cupcakes looks so delcious, i copied the recipe just now :) By they way, it says preheat oven to 350, but bake at 375?

  13. Okay I see, thnks. Now I have to develop an elegant relationship with my spatula… The thing we have going now is more a blob-like fiendship :o

  14. oh boy do those look sinfully inviting! I could do with some right now. I can only imagine how it’ll taste like. YUMMY…

  15. Oooh… looks absolutely yum! One question though, how should I alter the baking time if i wanted to bake them as mini cupcakes?

  16. Anonymous – For mini cupcakes, you would probably have to bake them for around 11-14 minutes. Make sure to check them with a toothpick; minicupcakes can overbake quickly.

  17. hi, i am new to baking, can you explain whats ap flour? thks

  18. Hi anonymous. “AP flour” is “all purpose flour”, it is just a shortened way of writing it.

  19. I made these cupcakes this weekend and they were a big hit. Very tasty, a nicely dense cake and the icing has just the right amount of sweetness and peanut butter flavor. Bravo!
