Happy National Chocolate Cupcake Day! If there is one day a year to bake a dozen chocolate cupcakes, it is today — and these are the ones to bake.

Recipe Steps

Prep the pan and oven. Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners. Whisk the flour, sugar, cocoa, baking soda, and salt together in a large bowl.
Mix the batter. Whisk in the milk, oil, and egg until smooth, then pour in the hot water and stir until thin and glossy (the batter will be loose — that is the secret to a fudgy crumb). Divide among the liners, filling each about two-thirds full.
Add the peanut butter center. Drop a small spoonful (about 2 tsp) of peanut butter into the middle of each cup of batter; it will sink as the cupcakes bake. Bake 15 minutes, or until the tops spring back lightly. Cool in the pan 5 minutes, then move to a rack.
Whip the frosting and ganache. Beat the remaining peanut butter, softened butter, powdered sugar, vanilla, and milk until fluffy, adding milk a splash at a time. Warm the cream until steaming, pour over the chocolate chips, rest 1 minute, and stir into a glossy ganache.
Swirl, drizzle, and finish. Pipe or spoon a tall swirl of peanut butter frosting onto each cooled cupcake, drizzle with warm ganache, and shower with chopped peanuts. Serve right away — or try to wait.

Tips & Variations

Do not overbake. At 15 minutes the cupcakes look just set; that keeps the center gooey. A toothpick should come out with a few moist crumbs, not clean.
Room-temperature dairy matters. Cold milk and eggs curdle a hot-water batter and make it dense — set them out 20 minutes before you start.
Going natural: use no-stir natural peanut butter for the frosting; pure natural PB separates and turns grainy in frosting.
Salt on top. A tiny flake of sea salt over the ganache makes the chocolate taste more chocolatey — try it on two and see.

Frequently Asked Questions

Can I make these chocolate peanut butter cupcakes ahead of time?

Yes. Bake the cupcakes up to 2 days ahead and store them unfrosted in an airtight container at room temperature. Whip the frosting and ganache the day you serve — they take under 10 minutes — so everything tastes freshly made.

How do I store leftover cupcakes?

Keep frosted cupcakes in an airtight container at room temperature for up to 3 days. The peanut butter frosting is shelf-stable for that window, so no fridge needed — chilling dries out the crumb.

Can I use natural peanut butter?

For the gooey center, yes — any smooth peanut butter melts fine inside the batter. For the frosting, stick with a no-stir peanut butter (creamy commercial style); natural PB separates and makes the frosting grainy.

Can I freeze these cupcakes?

Absolutely. Freeze unfrosted cupcakes in a zip-top bag for up to 2 months. Thaw at room temperature for about an hour, then frost and drizzle fresh — they taste like the day they were baked.
