Ingredients
Cupcake Batter
- 1 1/2 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup granulated sugar
- 1/2 cup brown sugar (packed)
- 2 large eggs
- 1/2 cup buttermilk (or regular milk)
- 1/2 cup vegetable oil
- 1 tsp vanilla extract
- 1/2 cup boiling water
Peanut Butter Filling
- 1/2 cup peanut butter (smooth or chunky, your preference)
- 1/4 cup powdered sugar
Peanut Butter Frosting
- 1/2 cup unsalted butter (softened)
- 1/2 cup peanut butter (creamy)
- 3 cups powdered sugar
- 1 tsp vanilla extract
- 2 tbsp milk (adjust for desired consistency)
Instructions
- Prepare Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt to ensure they are evenly combined.
- Mix Wet Ingredients: In a large bowl, beat together granulated sugar, brown sugar, eggs, buttermilk, vegetable oil, and vanilla extract until the mixture is smooth and homogeneous.
- Combine Dry with Wet: Gradually add the dry ingredients into the wet mixture, mixing just until combined to avoid overmixing which can toughen the cupcakes.
- Add Boiling Water: Pour in the boiling water and mix gently; the batter will become thin, but this is expected and will result in moist cupcakes.
- Fill Cupcake Liners: Spoon the batter into a prepared muffin tin lined with cupcake liners, filling each about halfway full.
- Add Peanut Butter Center: Drop about 1 teaspoon of peanut butter into the center of each cupcake, then cover with more batter until the liners are about three-quarters full.
- Bake Cupcakes: Bake in a preheated oven at 350°F (175°C) for 18-22 minutes, or until a toothpick inserted near the edges comes out clean but the peanut butter center remains gooey. Allow cupcakes to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
- Make Peanut Butter Filling: In a small bowl, mix the peanut butter and powdered sugar together until smooth and well combined. Set aside.
- Prepare Peanut Butter Frosting: In a medium bowl, beat softened butter with creamy peanut butter until light and creamy. Gradually add powdered sugar, 1 cup at a time, mixing thoroughly each time.
- Adjust Frosting Consistency: Mix in vanilla extract and milk, beating until the frosting reaches a spreadable consistency. Add more milk if too thick, or more powdered sugar if too thin.
- Fill Cupcakes: Once cupcakes are completely cooled, use a small knife to cut a small hole in the center of each cupcake and fill with the peanut butter filling.
- Frost Cupcakes: Top each filled cupcake with a swirl of peanut butter frosting using a piping bag or knife.
- Optional Decoration: For extra flair, drizzle melted chocolate over the cupcakes or sprinkle with chopped peanuts for added texture and flavor.
Notes
- The batter will be thin after adding boiling water, which is normal and helps produce moist cupcakes.
- Use either smooth or chunky peanut butter based on your texture preference for the filling.
- If you don’t have buttermilk, regular milk with a teaspoon of lemon juice or vinegar can be used as a substitute.
- To ensure gooey centers, do not overbake the cupcakes; watch closely towards the end of baking time.
- Store cupcakes in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days.
- Bring refrigerated cupcakes to room temperature or warm slightly before serving for best flavor and texture.
