Introduction

These Peanut Butter Chocolate Cupcakes combine rich, moist chocolate cake with creamy peanut butter frosting for the ultimate indulgence. Perfectly balanced and decadently topped with mini peanut butter cups and chopped peanuts, they are a treat for any occasion.

The image shows a cut chocolate cupcake with three layers: the bottom layer is dark and moist chocolate cake, the middle layer is a smooth light brown peanut butter filling that oozes out, and the top layer is thick, creamy beige peanut butter frosting swirled in two rounded peaks. The frosting is sprinkled with small crunchy peanut pieces and topped with two small round peanut butter chocolates, one whole and one cut in half, positioned on the right side of the frosting.

Ingredients

120 g boiling water
200 g granulated sugar
50 g unsweetened Dutch cocoa powder
160 g all-purpose flour
1 tsp instant espresso powder
1/2 tsp baking powder
1/2 tsp baking soda
½ tsp salt
120 g sour cream (14-18%), room temperature
75 g vegetable oil
2 large eggs, room temperature
1 ½ tsp vanilla extract
150 g butter, room temperature
160 g creamy peanut butter
230 g powdered sugar
1-1 ½ tbsp milk, room temperature
1 tsp vanilla extract
12 tsp creamy peanut butter (for filling)
12-24 Reese’s mini peanut butter cups (for decoration)
Small handful of peanuts (for decoration)

Instructions

Step 1: Preheat the oven to 160ºC (320ºF) conventional. Line a 12-cup cupcake tray with liners.
Step 2: Boil the water and set aside to cool slightly while preparing other ingredients.
Step 3: In a large bowl, combine all dry ingredients: sugar, cocoa powder, flour, espresso powder, baking powder, baking soda, and salt. Stir to mix evenly.
Step 4: In another bowl, whisk together all wet ingredients: sour cream, vegetable oil, eggs, vanilla extract, and the warm boiled water. Whisk gently to combine without overmixing the eggs.
Step 5: Gradually add the wet ingredients to the dry, stirring gently until the batter is smooth and lump-free.
Step 6: Divide the batter evenly into the cupcake liners and bake for 20-23 minutes. Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Step 7: For the frosting, sift the powdered sugar. Beat the butter and peanut butter together on medium-high speed for 2 minutes using a stand or hand mixer.
Step 8: Add the powdered sugar, vanilla, and milk in two parts, mixing on low speed until incorporated. Beat for an additional minute until smooth and fluffy.
Step 9: Use the end of a piping tip or similar tool to core out the center of each cooled cupcake. Fill each center with 1 teaspoon of creamy peanut butter.
Step 10: Pipe the peanut butter frosting on top using a round tip (such as Wilton 1A). Decorate with mini peanut butter cups and chopped peanuts.

Tips & Variations

To deepen the chocolate flavor, try using espresso powder or coffee instead of boiling water.
If preferred, substitute creamy peanut butter with crunchy for added texture in the frosting and filling.
For a dairy-free version, use non-dairy sour cream and butter alternatives.
Chill the frosting slightly if it feels too soft for piping.

Storage

Store the cupcakes in an airtight container in the refrigerator for up to 4 days. Bring to room temperature before serving for the best flavor and texture. They can also be frozen for up to 2 months; thaw overnight in the fridge and then bring to room temperature.

FAQs

Can I make the cupcakes ahead of time?

Yes, you can bake the cupcakes a day in advance and store them in an airtight container. It’s best to frost them the day you plan to serve for the freshest taste.

Can I use peanut butter powder instead of creamy peanut butter?

Peanut butter powder has a different texture and less fat, so it may change the consistency of the frosting. For best results, stick with creamy peanut butter for the filling and frosting.
