Ingredients

• 1 cup all-purpose flour — Provides structure for the cupcakes; spoon into the cup and level for accuracy.
• 1/2 cup Hershey’s Special Dark cocoa powder — Gives the cupcakes a bold, dark chocolate flavor.
• 1 teaspoon baking soda — Helps the cupcakes rise and creates a light texture.
• 1/2 teaspoon baking powder — Adds lift and ensures a tender crumb.
• 1/2 teaspoon salt — Balances sweetness and enhances chocolate flavor.
• 1/3 cup vegetable oil — Keeps the cupcakes moist and tender; neutral-flavored oil is best.
• 1 cup granulated sugar — Sweetens the batter and helps with browning.
• 1 large egg — Binds the batter and adds richness.
• 1 teaspoon pure vanilla extract — Adds depth and rounds out flavors.
• 1/2 cup buttermilk — Adds moisture and a slight tang to tenderize the crumb.
• 1/2 cup hot coffee or hot water — Intensifies the chocolate flavor; use coffee for deeper taste or hot water if you prefer no coffee flavor.
• 5 tablespoons unsalted butter, softened — Base for the frosting; softened butter whips up light and creamy.
• 1 cup creamy peanut butter — Provides the peanut butter flavor and structure for the frosting.
• 1 cup confectioners’ sugar — Sweetens and stabilizes the frosting for spreading.
• 1/3 cup heavy cream — Adjusts frosting consistency and adds richness.
• 1 teaspoon pure vanilla extract — Enhances the frosting flavor.
• 1/4 teaspoon salt — Balances sweetness in the frosting and lifts peanut butter notes.
• Crushed Reese’s Pieces for topping (optional) — Adds crunch and a playful peanut-chocolate garnish.

Step-by-step Instructions

1. Preheat the oven to 350°F (177°C) and line a muffin pan with cupcake liners. Place the rack in the center of the oven for even baking.
2. In a medium bowl, whisk together the 1 cup all-purpose flour, 1/2 cup Hershey’s Special Dark cocoa powder, 1 teaspoon baking soda, 1/2 teaspoon baking powder, and 1/2 teaspoon salt until evenly combined.
3. In a large bowl, whisk together the 1/3 cup vegetable oil, 1 cup granulated sugar, 1 large egg, 1 teaspoon pure vanilla extract, and 1/2 cup buttermilk until the mixture is smooth and uniform.
4. Gradually combine the dry ingredients with the wet ingredients, stirring gently until just incorporated. Then add 1/2 cup hot coffee or hot water and whisk until the batter is smooth. Avoid overmixing to keep the cupcakes tender.
5. Fill the cupcake liners about 2/3 full with the batter. Bake for 20 to 22 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pan once halfway through baking if your oven has hot spots.
6. Let the cupcakes cool in the pan for 10 minutes, then transfer them to a cooling rack to cool completely before frosting. Cooling completely prevents the frosting from melting.
7. For the frosting, beat the 5 tablespoons unsalted butter in a bowl until creamy. Add the 1 cup creamy peanut butter, 1 cup confectioners’ sugar, 1/3 cup heavy cream, 1 teaspoon pure vanilla extract, and 1/4 teaspoon salt. Beat until the mixture is combined and fluffy. If the frosting is too thick, add a little more cream; if too thin, add a touch more confectioners sugar.
8. Frost the cooled cupcakes generously using an offset spatula or piping bag, creating a smooth or swirled top as you prefer. Sprinkle crushed Reese’s Pieces on top, if desired.
9. Store any leftover cupcakes in the refrigerator for up to 3 days. Bring to room temperature before serving for the best flavor and texture.
