Ingredients

• 1 cup all-purpose flour, for structure and a 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 and lighten the texture.
• 1/2 teaspoon baking powder, for additional lift and a soft crumb.
• 1/2 teaspoon salt, to balance sweetness and enhance chocolate notes.
• 1/3 cup vegetable oil, keeps the cupcakes moist and tender.
• 1 cup granulated sugar, for sweetness and to help with texture.
• 1 large egg, adds structure and richness.
• 1 teaspoon pure vanilla extract, brightens and rounds the chocolate flavor.
• 1/2 cup buttermilk, adds tang and helps create a tender crumb.
• 1/2 cup hot coffee or hot water, intensifies the chocolate and thins the batter for even baking.
• 5 tablespoons unsalted butter, softened, for a creamy frosting base.
• 1 cup creamy peanut butter, provides the classic peanut butter flavor and structure in the frosting.
• 1 cup confectioners’ sugar, sweetens and stabilizes the frosting.
• 1/3 cup heavy cream, loosens and lightens the frosting for easy spreading.
• 1 teaspoon pure vanilla extract for frosting, adds fragrant depth.
• 1/4 teaspoon salt for frosting, balances sweetness and enhances peanut flavor.
• Crushed Reese’s Pieces for topping (optional), for extra color, crunch, and peanut-chocolate nostalgia.

I like to keep the cocoa measurement exact to preserve the dark chocolate intensity, and the hot coffee option will amplify the chocolate taste if you choose it. For a meal pairing idea after baking, check this savory chicken and pasta suggestion: baked Caesar chicken with creamy Parmesan pasta.

Step-by-step Instructions

1. Preheat the oven to 350°F (177°C) and line a muffin pan with cupcake liners. Position a rack in the center of the oven for even baking.
2. In a medium bowl, whisk together the flour, Hershey’s Special Dark cocoa powder, baking soda, baking powder, and salt until evenly combined. Sifting is optional but helps remove lumps.
3. In a large bowl, whisk together the vegetable oil, granulated sugar, large egg, vanilla extract, and buttermilk until well combined and smooth. A hand whisk or electric mixer on low works fine.
4. Gradually add the dry ingredients to the wet mixture, mixing until just combined. Pour in the 1/2 cup hot coffee or hot water and whisk until the batter is smooth and glossy. The hot liquid loosens the batter and deepens the chocolate flavor.
5. Fill the cupcake liners about 2/3 full with the batter. A cookie scoop helps portion evenly. Bake for 20 to 22 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
6. Let the cupcakes cool in the pan for 10 minutes, then transfer them to a cooling rack to finish cooling completely before frosting. Cooling fully prevents the frosting from melting.
7. For the frosting, beat the softened unsalted butter in a bowl until creamy. Add the creamy peanut butter, confectioners’ sugar, heavy cream, vanilla extract for frosting, and the 1/4 teaspoon salt. Beat until light and fluffy, adding a splash more cream if needed to reach spreadable consistency.
8. Frost the cooled cupcakes using a spatula or piping bag. Sprinkle with crushed Reese’s Pieces if desired for a playful crunch and color.
9. Store leftover cupcakes in the refrigerator for up to 3 days, and bring to room temperature before serving for the best texture.

Frequently Asked Questions

1. How do I make the cupcakes more moist?
   Use the full 1/3 cup vegetable oil and do not overmix the batter. The buttermilk also helps keep them tender.

2. Can I use natural peanut butter in the frosting?
   Yes. Natural peanut butter will work, but the texture may be slightly thinner and you might need to chill the frosting briefly to firm it up.

3. Do I have to use hot coffee?
   No, you can use hot water. Coffee enhances the chocolate flavor but water will keep the recipe simple.

4. How long do frosted cupcakes last at room temperature?
   Because the frosting contains heavy cream and butter, store frosted cupcakes in the refrigerator and consume within 3 days.

5. Can I make the batter ahead of time?
   You can prepare the batter and refrigerate it for a few hours, but allow it to come to room temperature before baking for consistent rise.

People Also Ask

1. What does Hershey’s Special Dark cocoa powder do in the recipe?
   It gives a deeper, more intense chocolate flavor and a darker color than natural cocoa powder.

2. Why is buttermilk used in cupcakes?
   Buttermilk adds acidity that tenderizes the crumb and contributes a subtle tang that balances sweetness.

3. How can I tell when cupcakes are done?
   Insert a toothpick into the center; it should come out clean or with a few moist crumbs, not wet batter.

4. Can I make these gluten free using a 1-to-1 flour?
   This recipe has not been tested with gluten free flour, and results may vary. If you try a 1-to-1 blend, expect possible texture differences.

5. How do I prevent the frosting from becoming too runny?
   Chill the frosting briefly if it loosens, or add a little more confectioners’ sugar to thicken without changing flavors.

6. Are these cupcakes suitable for parties?
   Yes, they are sturdy, easy to transport, and crowd-pleasing thanks to the classic chocolate and peanut butter pairing.
