Directions

Preheat the oven to 350°F (175°C) and line a cupcake pan with liners.
Make the cupcake batter: In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
In another bowl, beat sugar, eggs, milk, oil, and vanilla extract until well combined.
Gradually mix in the dry ingredients, then slowly add the boiling water. The batter will be thin, but that’s normal.
Bake the cupcakes: Fill the liners about two-thirds full and bake for 18-20 minutes or until a toothpick inserted in the center comes out clean. Let them cool completely.
Prepare the frosting: Beat the butter and peanut butter until smooth. Gradually add powdered sugar, then mix in vanilla and heavy cream until fluffy.
Frost the cupcakes: Pipe or spread the frosting onto the cooled cupcakes.
Add the finishing touch: Place a mini peanut butter cup on top of each cupcake for decoration.

FAQs

How do I make these cupcakes extra moist?

Using boiling water in the batter helps create a moist and tender texture. Don’t overbake them, as that can dry them out.

Can I use natural peanut butter for the frosting?

It’s best to use creamy, processed peanut butter for a smooth frosting. Natural peanut butter can be too oily or grainy.

Can I make these cupcakes ahead of time?

Yes! Bake the cupcakes in advance and store them at room temperature or freeze them. Frost them just before serving for the best texture.

What can I use instead of peanut butter cups?

You can top them with chocolate chips, chopped peanuts, or a drizzle of melted peanut butter.

Can I make these gluten-free?

Yes, substitute the all-purpose flour with a gluten-free 1:1 baking flour.

How do I get the perfect frosting consistency?

If the frosting is too thick, add a little more heavy cream. If it’s too thin, add more powdered sugar until you reach the desired texture.

Can I use a different frosting?

Absolutely! Chocolate ganache, vanilla buttercream, or even a cream cheese frosting would pair well.

Do I need to refrigerate these cupcakes?

They can stay at room temperature for a couple of days, but if you want them to last longer, refrigerate them in an airtight container.

How do I prevent cupcakes from sinking in the middle?

Ensure you’re measuring ingredients correctly, don’t overmix the batter, and avoid opening the oven door while baking.

Can I use a cake mix instead of making the cupcakes from scratch?

Yes! Use a chocolate cake mix and follow the box instructions, then make the peanut butter frosting from scratch.
