Ingredients

• 1 cup all-purpose flour, provides structure and a tender crumb.
• 1/2 cup Hershey’s Special Dark cocoa powder, gives concentrated chocolate flavor and deep color.
• 1 teaspoon baking soda, helps the cupcakes rise.
• 1/2 teaspoon baking powder, adds extra lift and lightness.
• 1/2 teaspoon salt, balances sweetness and enhances chocolate notes.
• 1/3 cup vegetable oil, keeps the cupcakes moist and tender.
• 1 cup granulated sugar, sweetens and contributes to texture.
• 1 large egg, binds ingredients and adds richness.
• 1 teaspoon pure vanilla extract, rounds the flavor with warm aromatics.
• 1/2 cup buttermilk, adds tang and keeps the cake tender.
• 1/2 cup hot coffee or hot water, intensifies the chocolate flavor and thins the batter.
• 5 tablespoons unsalted butter, softened, for the frosting base and creaminess.
• 1 cup creamy peanut butter, provides nutty flavor and body to the frosting.
• 1 cup confectioners’ sugar, sweetens and helps the frosting hold shape.
• 1/3 cup heavy cream, loosens the frosting to a spreadable consistency.
• 1 teaspoon pure vanilla extract, adds flavor depth to the frosting.
• 1/4 teaspoon salt, balances the sweetness in the frosting.
• Crushed Reese’s Pieces for topping (optional), adds crunch and candy flavor on top.

Step-by-Step Instructions

1. Preheat the oven to 350°F (177°C) and line a muffin pan with cupcake liners. This keeps cleanup easy and helps the cupcakes release cleanly.
2. In a medium bowl, whisk together the flour, Hershey’s Special Dark cocoa powder, baking soda, baking powder, and salt until evenly combined.
3. In a large bowl, whisk together the vegetable oil, granulated sugar, egg, vanilla extract, and buttermilk until smooth and well combined.
4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Pour in the 1/2 cup hot coffee or hot water and whisk until the batter is smooth and free of lumps. Tip: the hot liquid blooms the cocoa for richer chocolate flavor.
5. 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.
6. 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.
7. 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. Tip: start on low speed to avoid sugar clouds, then increase speed to whip air into the frosting.
8. Adjust the consistency by adding more confectioners’ sugar to thicken or a splash more heavy cream to thin, if needed.
9. Frost the cooled cupcakes generously using a piping bag or an offset spatula, and sprinkle crushed Reese’s Pieces on top if desired.
10. Store any leftover cupcakes in the refrigerator for up to 3 days.

Tips, Storage & Variations

• Tips
  • Use hot coffee if you want a deeper chocolate flavor, or hot water if you prefer a neutral boost.
  • Fill liners evenly using an ice cream scoop for uniform cupcakes.
  • Let cupcakes cool completely before frosting to avoid melting the frosting.
• Storage
  • Store frosted cupcakes in an airtight container in the refrigerator for up to 3 days.
  • Bring refrigerated cupcakes to room temperature before serving for best texture and flavor.
• Freezing
  • Freeze unfrosted cupcakes in a single layer on a baking sheet until firm, then transfer to a freezer bag for up to 2 months. Thaw and frost when ready to serve.
  • For frosted cupcakes, freeze on a tray until firm, then wrap individually and freeze up to 1 month. Thaw overnight in the refrigerator.
• Flavor variations using existing ingredients only
  • Swap hot water with hot coffee to amplify chocolate notes.
  • Omit crushed Reese’s Pieces for a smoother top, or add them for candy crunch.
  • For a stiffer frosting for piping, add a little more confectioners’ sugar; for a softer glaze, add a teaspoon or two more heavy cream.
  • Increase peanut butter in the frosting slightly for a stronger nutty profile.

FAQ

1. Can I make the batter ahead of time?
   Yes. You can mix the batter, cover, and refrigerate for up to 24 hours. Bring to room temperature and stir gently before baking.
2. Can I use natural peanut butter instead of creamy peanut butter?
   Yes. Natural peanut butter will work, but the frosting may be slightly looser due to oil separation. Chill briefly if needed.
3. Do I have to use hot coffee?
   No. Hot water works fine and still activates the cocoa. Coffee simply deepens the chocolate flavor.
4. How do I fix a runny frosting?
   Add a few tablespoons of confectioners’ sugar and beat until thicker, or chill the frosting for 10 to 15 minutes.
5. Can I make cupcakes gluten-free?
   This recipe uses all-purpose flour as written, so to make it gluten-free you would need to substitute a gluten-free flour blend, which would change the ingredient list and is not covered here.
6. How long will unfrosted cupcakes last at room temperature?
   Unfrosted cupcakes kept in an airtight container can stay fresh at room temperature for up to 2 days.

People Also Ask

1. What does hot coffee do in chocolate cake batter?
   Hot coffee enhances and intensifies the chocolate flavor by blooming the cocoa powder and bringing out its natural richness.
2. Is buttermilk necessary in cupcake recipes?
   Buttermilk adds slight acidity and tenderness, improving texture and rise, but it can be replaced with milk plus a small amount of vinegar in other recipes.
3. Can I reduce the sugar in the cupcakes?
   You can reduce sugar slightly, but it may affect texture and moisture. This recipe is balanced for sweetness with the peanut butter frosting.
4. Why are my cupcakes dense?
   Overmixing after adding flour or using too little leavening can create density. Mix until just combined and measure leavening carefully.
5. How do I prevent frosting from separating?
   Use room temperature ingredients and beat until smooth. If separation occurs with natural peanut butter, chilling and rewhipping helps.
6. Can I pipe the frosting decoratively?
   Yes, the frosting is stable enough to pipe. If piping fine details, chill the frosting briefly to firm it up.
7. Will the cupcakes keep their texture after refrigeration?
   Refrigeration can slightly firm the crumb. Let them warm to room temperature before serving for best texture.
8. Is confectioners’ sugar necessary for the frosting?
   Confectioners’ sugar provides structure and a smooth texture. Granulated sugar would be gritty and is not recommended in this frosting.

Conclusion
These dark chocolate cupcakes with peanut butter frosting are a reliable crowd-pleaser, balancing deep cocoa flavor with creamy, slightly salty peanut butter frosting. They are easy to make and adaptable with simple variations like swapping hot water for coffee or adding crushed Reese’s Pieces for texture.
