- 1 cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
Wet Ingredients:
- 1 ¼ cups granulated sugar
- ¾ cup packed brown sugar
- ½ cup melted butter or vegetable oil
- 3 large eggs
- 2 teaspoons vanilla extract
- 1 ¼ cups whole milk
- ½ cup warm coffee or hot water
Peanut Butter Filling:
- 1 cup creamy peanut butter
- ½ cup powdered sugar
- 3 tablespoons unsalted butter, softened
- 1 teaspoon vanilla extract

- 10 ounces semisweet chocolate, finely chopped

Step-by-Step Instructions
Making the Cupcake Batter
- Preheat the Oven Set your oven to 350°F (175°C) and prepare a muffin tin with cupcake liners.
- Prepare the Dry Mixture In a mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until evenly combined.
- Mix the Wet Ingredients In a separate large bowl, beat together the granulated sugar, brown sugar, and melted butter until smooth. Add in the eggs one at a time, ensuring each is fully incorporated. Stir in the vanilla extract.
- Combine Wet and Dry Ingredients Gradually mix the dry ingredients into the wet ingredients, alternating with the milk. Stir gently to avoid overmixing, which can lead to dense cupcakes. Finally, pour in the hot coffee or water and stir until just combined. The batter will be slightly runny—this helps keep the cupcakes moist.
- Fill the Cupcake Liners Divide the batter evenly among the liners, filling each about two-thirds full to give them room to rise.
- Bake to Perfection Place the tray in the oven and bake for 18-22 minutes or until a toothpick inserted in the center comes out clean. Allow them to cool in the pan for a few minutes before transferring them to a wire rack to cool completely.
Preparing the Peanut Butter Filling
- Combine Ingredients In a mixing bowl, blend together the peanut butter, powdered sugar, softened butter, and vanilla extract until the mixture is smooth and creamy.
- Inject the Filling Once the cupcakes have cooled, use a piping bag with a small round tip or a spoon to insert the peanut butter mixture into the center of each cupcake. If using a spoon, cut a small hole in the top of the cupcake, fill it, and place the cutout piece back on top.
Making the Chocolate Ganache Frosting
- Heat the Cream In a small saucepan, heat the heavy cream until it begins to simmer. Do not let it boil.
- Melt the Chocolate Pour the hot cream over the chopped chocolate and let it sit for a minute before whisking until smooth. Stir in the butter to enhance the richness and shine of the ganache.
- Frost the Cupcakes Once the ganache has slightly cooled but is still spreadable, frost each cupcake using a piping bag or a spoon for a smooth finish.
Adding the Peanut Butter Drizzle
- Melt the Peanut Butter Microwave the peanut butter for about 20-30 seconds until it reaches a pourable consistency.
- Drizzle with Precision Using a spoon or a piping bag, drizzle the melted peanut butter over the frosted cupcakes for a visually stunning finish and an extra boost of peanut butter flavor.
Why These Cupcakes Are a Must-Try
- Incredibly Moist: The use of coffee or hot water in the batter enhances the chocolate flavor and keeps the cupcakes soft and tender.
- Balanced Sweetness: The slight saltiness of peanut butter complements the deep cocoa flavors perfectly.
- Textural Delight: The creamy peanut butter center adds an extra layer of indulgence.
- Professional Look, Homemade Love: With the glossy ganache and peanut butter drizzle, these cupcakes look bakery-quality while being made right in your kitchen.
- Easily Customizable: Swap peanut butter for almond or cashew butter, add chopped peanuts for extra crunch, or experiment with white chocolate for a twist!
Serving and Pairing Ideas
For the ultimate experience, enjoy these cupcakes with a glass of cold milk, a cup of freshly brewed coffee, or a scoop of vanilla ice cream. If you’re serving them for an occasion, consider adding a dusting of cocoa powder or chocolate shavings for an extra gourmet touch.
Storage and Freshness Tips
- Store at room temperature in an airtight container for up to three days.
- Keep in the refrigerator for up to a week, but allow them to come to room temperature before serving.
- For long-term storage, freeze them (without the ganache) in an airtight container for up to three months. When ready to eat, thaw at room temperature and frost fresh.
