Ingredients

1 cup all-purpose flour, for structure and tender crumb.
1/2 cup Hershey’s Special Dark cocoa powder, for deep, rich chocolate flavor.
1 teaspoon baking soda, to help the cupcakes rise.
1/2 teaspoon baking powder, for extra lift and lightness.
1/2 teaspoon salt, to balance sweetness and enhance flavor.
1/3 cup vegetable oil, keeps the cupcakes moist and tender.
1 cup granulated sugar, for sweetness and texture.
1 large egg, adds structure and richness.
1 teaspoon pure vanilla extract, for warm, rounded flavor.
1/2 cup buttermilk, adds tang and tenderizes the crumb.
1/2 cup hot coffee or hot water, intensifies the chocolate without tasting like coffee.
5 tablespoons unsalted butter, softened, for the frosting base and creaminess.
1 cup creamy peanut butter, for rich peanut flavor and smooth texture in the frosting.
1 cup confectioners’ sugar, sweetens and stabilizes the frosting.
1/3 cup heavy cream, thins and lightens the frosting for spreadable consistency.
1 teaspoon pure vanilla extract, boosts flavor in the frosting.
1/4 teaspoon salt, balances sweetness in the frosting.
Crushed Reese’s Pieces for topping (optional), for crunch and extra peanut butter candy flavor.

Step-by-Step Instructions

Preheat and prepare. Preheat the oven to 350°F (177°C) and line a muffin pan with cupcake liners. Position a rack in the middle of the oven so the cupcakes bake evenly.
Mix dry ingredients. In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until well combined and aerated.
Combine wet ingredients. In a large bowl, whisk together the vegetable oil, granulated sugar, egg, vanilla extract, and buttermilk until smooth and homogeneous.
Bring batter together. Gradually add the dry ingredients to the wet mixture, mixing gently until mostly combined. Then add the 1/2 cup hot coffee or hot water and whisk until the batter is smooth. A thin batter is normal and gives a moist cupcake.
Fill liners and bake. Fill the cupcake liners about 2/3 full with batter. Bake for 20 to 22 minutes or until a toothpick inserted into the center comes out clean. Rotate the pan halfway through baking if your oven has hot spots.
Cool briefly then finish cooling. Let the cupcakes cool in the pan for 10 minutes, then transfer them to a cooling rack to cool completely before frosting. Frosting warm cupcakes will melt the frosting.
Make the frosting. For the frosting, beat the softened butter in a bowl until creamy. Add the creamy peanut butter, confectioners’ sugar, heavy cream, vanilla extract, and salt. Beat until the mixture is combined and fluffy. If the frosting is too stiff, add a little more heavy cream, 1 teaspoon at a time.
Frost and garnish. Frost the cooled cupcakes generously using a spatula or piping bag. Sprinkle crushed Reese’s Pieces on top if desired for color and crunch.
Store leftovers. Store any leftover cupcakes in the refrigerator for up to 3 days. Let chilled cupcakes come to room temperature for 15 to 30 minutes before serving for the best texture.
