Chocolate drizzle (melted chocolate or chocolate syrup)
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
2. Make the Cupcake Batter
In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
Add the eggs and vanilla extract, and mix until well combined.
In a separate bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk, and mix until just combined.
3. Prepare the Peanut Butter Filling
In a small bowl, mix the peanut butter, powdered sugar, and milk until smooth and slightly thick.
4. Assemble the Cupcakes
Fill each cupcake liner about halfway with the chocolate batter.
Add a small spoonful of the peanut butter filling to the center of each cupcake.
Top with more chocolate batter until the liners are about 3/4 full.
5. Bake the Cupcakes
Bake for 18-20 minutes, or until a toothpick inserted into the cupcake (not the filling) comes out clean.
Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
6. Make the Peanut Butter Frosting
In a medium bowl, beat the peanut butter and softened butter until smooth.
Gradually add the powdered sugar, milk, and vanilla extract, and beat until creamy and fluffy.
7. Frost and Decorate
Once the cupcakes are completely cool, frost them with the peanut butter frosting using a piping bag or spatula.
Add optional toppings like chopped peanuts, chocolate chips, or a chocolate drizzle.
8. Serve and Enjoy
