Ingredients

• 1 cup all-purpose flour — the structure for the cupcakes.
• 1/2 cup Hershey’s Special Dark cocoa powder — gives deep chocolate flavor and color.
• 1 teaspoon baking soda — helps the cupcakes rise and stay light.
• 1/2 teaspoon baking powder — adds extra lift for a tender crumb.
• 1/2 teaspoon salt — balances sweetness and enhances chocolate flavor.
• 1/3 cup vegetable oil — keeps the cupcakes moist and tender.
• 1 cup granulated sugar — sweetens and aids texture.
• 1 large egg — binds ingredients and adds richness.
• 1 teaspoon pure vanilla extract — boosts overall flavor.
• 1/2 cup buttermilk — adds tang and tenderizes the crumb.
• 1/2 cup hot coffee or hot water — intensifies the chocolate and helps dissolve the cocoa.
• 5 tablespoons unsalted butter, softened — base for the peanut butter frosting and adds richness.
• 1 cup creamy peanut butter — primary flavor for the frosting, use creamy for smooth texture.
• 1 cup confectioners’ sugar — sweetens and stabilizes the frosting.
• 1/3 cup heavy cream — thins and lightens the frosting for pipeable consistency.

Step-by-Step Instructions

1. Preheat and prepare. Preheat the oven to 350°F (177°C) and line a muffin pan with cupcake liners. Using liners will make removal and cleanup easier.

2. Whisk dry ingredients. In a medium bowl, whisk together the flour, Hershey’s Special Dark cocoa powder, baking soda, baking powder, and salt until evenly combined.

3. Combine wet ingredients. In a large bowl, whisk together the vegetable oil, granulated sugar, large egg, vanilla extract, and buttermilk until smooth and well blended.

4. Mix dry into wet. Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Do not overmix to keep cupcakes tender.

5. Add hot liquid. Stir in the 1/2 cup hot coffee or hot water until the batter is smooth. The batter will be fairly thin, which will yield a moist cupcake.

6. 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 in the center comes out clean or with a few moist crumbs.

7. Cool the cupcakes. Let the cupcakes cool in the pan for 10 minutes, then transfer them to a cooling rack to cool completely before frosting. Cooling fully prevents the frosting from melting.

8. Make the peanut butter frosting. Beat the 5 tablespoons softened unsalted butter 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. Mix on medium speed until light and fluffy. Adjust cream by tablespoonfuls if you need a thinner or thicker consistency.

9. Frost and finish. Frost the cooled cupcakes with the peanut butter frosting and sprinkle with crushed Reese’s Pieces if desired for extra crunch and color.

Small tip: If your frosting seems too soft, chill it briefly for 10 to 15 minutes to firm up for piping.

Tips, Storage & Variations

• Baking tips: Measure flour by spooning it into the cup and leveling with a knife to avoid dense cupcakes. Use hot coffee for a deeper chocolate flavor, or hot water if you prefer a neutral boost of moisture.
• Frosting tips: Beat the butter until very smooth before adding peanut butter to avoid lumps. Sift the confectioners’ sugar if it is clumpy.
• Storage: Store frosted cupcakes in an airtight container in the refrigerator for up to 3 days. Let cupcakes come to room temperature for 20 to 30 minutes before serving for best texture and flavor.
• Freezing: Freeze unfrosted cupcakes in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Thaw, then frost before serving. Frosted cupcakes can be frozen for up to 1 month; wrap individually and thaw in the fridge overnight.
• Flavor variations using only the existing ingredients:
  • Extra-moist chocolate: Swap hot water for hot coffee to intensify chocolate aroma.
  • Stronger peanut butter swirl: Warm a few tablespoons of peanut butter and swirl into batter before baking to add a peanut ribbon.
  • Candy crunch topping: Omit the crushed Reese’s Pieces or add more for extra texture.

FAQ

Q: Can I use natural peanut butter for the frosting?
A: Yes, but natural peanut butter may make the frosting slightly thinner and oilier. Chill briefly if needed.

Q: Can I make cupcakes ahead of time?
A: Bake and cool the cupcakes, then refrigerate frosted cupcakes up to 3 days. Unfrosted cupcakes freeze well for up to 2 months.

Q: How do I prevent the frosting from being too sweet?
A: Use a touch more salt in the frosting to balance sweetness, up to 1/4 teaspoon as specified.
