Ingredients You’ll Need

1 cup (125g) all-purpose flour: This is the base of our cupcakes, giving them structure. You can substitute it with a gluten-free blend if desired.
1/2 cup (42g) Hershey’s Special Dark cocoa powder: For that deep, rich chocolate flavor. Opt for natural cocoa for a lighter taste.
1 teaspoon baking soda: This provides lift, making your cupcakes light and fluffy!
1/2 teaspoon baking powder: To ensure those cupcakes rise and stay soft.
1/2 teaspoon salt: Boosts flavor and balances sweetness.
1/3 cup (80ml) vegetable oil: It gives moisture to the cupcakes. Can be swapped for melted coconut oil for a different flavor.
1 cup (200g) granulated sugar: This sweetens the cupcakes and contributes to their texture.
1 large egg, at room temperature: Acts as a binder and adds richness. Ensure it’s at room temp for even mixing.
1 teaspoon pure vanilla extract: Enhances the overall flavor profile. Always choose pure over imitation for the best results!
1/2 cup (120ml) buttermilk, at room temperature: Adds moisture and tenderness.
1/2 cup (120ml) hot coffee or hot water: The coffee intensifies the chocolate flavor, but feel free to use hot water if preferred.
5 Tablespoons (71g) unsalted butter, softened: This is for the frosting to achieve that creamy texture.
1 cup (250g) creamy peanut butter: The star of the frosting! Choose a smooth variety for easy spreading.
1 cup (120g) confectioners’ sugar: Adds sweetness and structure to the frosting.
1/3 cup (80ml) heavy cream: Makes the frosting fluffy and light.
1 teaspoon pure vanilla extract (again): Consistency is key for flavor!
1/4 teaspoon salt: Balances the sweetness in the frosting.
Optional: crushed Reese’s Pieces for topping: Adds crunch and that quintessential peanut butter taste.

How to Make Dark Chocolate Cupcakes with Creamy Peanut Butter Frosting

Preheat and Prepare: Start by preheating your oven to 350°F (177°C). Line a 12-count muffin pan with cupcake liners; this recipe usually yields about 14 to 16 cupcakes, so grab another muffin pan just in case or be ready to bake in batches.

Combine Dry Ingredients: In a medium bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt until evenly mixed. This will ensure even distribution and prevent clumps in your batter.

Whisk Wet Ingredients: In a separate large bowl, preferably with a spout for easier pouring, whisk together oil, sugar, egg, vanilla extract, and buttermilk until smooth. The mixture should be well combined and glossy. Pour the dry mix into the wet mix, then add the hot coffee or water, whisking gently until you achieve a thin but smooth batter.

Fill the Liners: Divide the batter evenly among the lined muffin cups, filling each about 2/3 full. This allows room for the cupcakes to rise without overflowing. The batter will look glossy, which is perfect!

Bake Until Golden: Place the muffin pan in your preheated oven and bake for 20-22 minutes. Keep an eye on them! They’re ready when a toothpick inserted into the center comes out clean, with just a few moist crumbs attached.

Cool Completely: After baking, let the cupcakes cool in the pan for about 10 minutes. Then, transfer them to a cooling rack to cool completely. Frosting warm cupcakes can be a sticky situation!

Make the Peanut Butter Frosting: Grab your mixer! In a bowl, beat the softened butter on medium speed until creamy, which takes about 2 minutes. Then add in the peanut butter, confectioners’ sugar, heavy cream, vanilla, and salt. Start on low speed to prevent sugar clouds, then increase to high speed and beat for a good 3 minutes until fluffy. If it’s too thin, add more sugar; if it’s thick, a splash more of cream should help!

Frost and Garnish: Once the cupcakes are completely cooled, frost them generously with your creamy peanut butter frosting. I love using a Wilton 1M piping tip for a beautiful swirl! To finish, sprinkle with crushed Reese’s Pieces for that fun crunch. Your creation is ready to wow everyone!

Storing & Reheating

Store any leftover cupcakes in an airtight container at room temperature for up to 2 days, but if frosted, keep them in the refrigerator for up to 3 days. Ensure they’re covered well to maintain freshness. For longer storage, you can freeze un-frosted cupcakes in a freezer-safe bag for up to 3 months. When you’re ready to enjoy them, allow them to thaw at room temperature for about 1 hour, then simply frost and indulge! Keep in mind that flavors might mellow slightly, but they’ll still taste amazing.

Chef’s Helpful Tips

Always use room-temperature ingredients for an even batter and better mixing results. This helps achieve a perfect rise.
If your frosting is too runny, add more confectioners’ sugar gradually until it thickens. Conversely, if it’s too thick, a splash of cream can help.
Be careful not to overmix the batter once you combine the wet and dry ingredients. Gentle movements keep the cupcakes fluffy!
Test your baking powder and baking soda’s effectiveness; they can lose potency over time. A quick test in warm water can help check their leavening power.
If you want to make these cupcakes ahead, bake them a day in advance and frost on the day you plan to serve.

Recipe FAQs

Can I use a different frosting?

Absolutely! While this recipe shines with creamy peanut butter frosting, you can try chocolate ganache, vanilla buttercream, or even a fruit-flavored frosting for a fresh twist. Each will give a different flavor experience to your cupcakes!

Can I make these cupcakes gluten-free?

Yes! Substitute the all-purpose flour with a 1:1 gluten-free flour blend. Just be sure to check that your baking soda and baking powder are gluten-free as well!

What can I substitute for buttermilk?

If you’re out of buttermilk, simply mix ½ cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5 minutes until it thickens slightly. This creates a similar tangy effect in your cupcakes.

How do I know when the cupcakes are done baking?

The best way to check is by inserting a toothpick into the center of a cupcake. It’s done when the toothpick comes out clean or with a few moist crumbs, but no wet batter. Plus, they should spring back slightly when you touch them.
