The Ultimate Chocolate Peanut Butter Cupcakes –
Rich chocolate cake topped with a two-toned swirl of chocolate and peanut butter frosting gets dressed up in an edible candy cupcake wrapper. Top it all off with the cutest mini “cupcake” to create the ultimate chocolate peanut butter dessert.
This is the perfect recipe for a peanut butter lover’s birthday bash or any occasion where you want to serve something seriously impressive.
There are a lot of steps involved but none of them are difficult. We’ll walk through them together.
Chocolate Cupcake Wrappers
Use the back of a spoon to paint foil cupcake liners with melted chocolate or Wilton candy melts. Let them set until they’re hard. Then, gently peel away the foil. You can do this days (or even weeks) in advance (if you have the will power to avoid snacking on them). Just put them in an airtight container and store it in a cool dry place.

Chocolate Cupcake Recipe
Let me preface this by confessing I gag on the “m” word. You know the one. It starts with “m” and rhymes with hoist? [Insert shudder.] Since I bake all the time, it’s as difficult to avoid as Pennsylvania pot hole in April.
Preheat the oven to 350-degrees. Whisk together 1 1/3 cups flour, 6 tablespoons unsweetened cocoa, 1 1/2 teaspoons baking soda, and 1/4 teaspoon of salt. Set aside.
Beat 1/2 cup softened butter with 1 1/2 cups packed brown sugar. Beat in one egg, then another.
Next, add the dry ingredients and 2/3 cup sour cream in three alternating batches. Stir in 2/3 cup boiling water.
Scoop batter into (non edible) cupcake liners to bake for 18-20 minutes. They’re done when a toothpick inserted in the center comes out clean. An ice cream scoop is the perfect size and helps ensure all of your cupcakes are uniform.
Cool your cakes in the pan for two minutes. Then put them on wire racks to cool completely. Once they’re cool, cut the centers out of them. A cupcake corer is a great tool for this. Here’s a link to my favorite cupcake corer.
If you don’t have one, you can use a spoon or a knife. Just be careful! Use the leftover centers to make cake balls, or snack on while you work.
You’ll fill those holes with peanut butter frosting, but first we have to make it!
Chocolate Peanut Butter Swirl Frosting
Each frosting flavor takes just a few minutes to whip together.
Beat 2 sticks of soft unsalted butter with 6 tablespoons unsweetened cocoa powder, 1 teaspoon of vanilla, and a pinch of salt. Gradually add 4 cups of powdered sugar. Finish with 1/4 cup heavy whipping cream.
Peanut Butter Frosting:
Beat 2 sticks of soft unsalted butter with 1 1/4 cups creamy peanut butter, and 2 teaspoons of vanilla. Gradually add 4 cups of powdered sugar. Finish with 6 tablespoons heavy whipping cream.
Place frostings into small piping bags. Stack the bags then slide them into a larger piping bag fitted with a Wilton 1M tip. Twist the tops together and firmly squeeze onto cupcakes.
If you’re a visual learner (like me), you can see more precise details on how to swirl two frosting flavors or colors together in my chocolate peanut butter swirl frosting post.
Candy Cupcake Toppers
Since we’re going all out over-the-top here, let’s crown those chocolate peanut butter bad boys with more chocolate and more peanut butter! Use a small open star tip to pipe peanut butter frosting onto peanut butter cups. They’ll look like itty-bitty cupcakes. Need more details? You can visit my full post on how to make candy cupcakes.

When people see the stunning presentation, they can tell a lot of love went into these. I delivered a batch to the local 911 dispatch center staff to thank them for dealing with my constant questions. I work with the crew often during my day job in the news business.
