Ingredients You’ll Need

For the Chocolate Cupcakes
Each ingredient here plays a vital role in creating the best chocolate cupcake you’ve ever tasted:
- Unsweetened Cocoa Powder: The foundation of the chocolate flavor. Choose a high-quality brand for the best results.
- Baking Soda: Reacts with the cocoa powder and hot water to give the cupcakes a tender rise.
- Boiling Water: Enhances the cocoa flavor and ensures a smooth batter.
- Unsalted Butter: Adds richness and flavor.
- Vegetable Oil: Keeps the cupcakes moist and tender.
- Granulated Sugar: Sweetens the cupcakes while helping to create a soft crumb.
- Vanilla Extract: Enhances the chocolate flavor with a warm, aromatic touch.
- Salt: Balances the sweetness and deepens the overall flavor.
- Eggs: Add structure and richness.
- Heavy Cream: Creates a luxurious texture and keeps the cupcakes moist.
- All-Purpose Flour: Provides structure while keeping the crumb soft and fluffy.
For the Chocolate Buttercream Frosting
- Butter: A mix of unsalted and salted butter gives the frosting its creamy, melt-in-your-mouth texture.
- Powdered Sugar: Sweetens and thickens the frosting while keeping it smooth.
- Unsweetened Cocoa Powder: Creates the rich chocolate flavor we all crave.
- Vanilla Extract: Adds a touch of warmth to balance the chocolate.
- Heavy Cream: Makes the frosting silky and spreadable.
How to Make the Perfect Chocolate Cupcakes?

1. Prepare Your Baking Essentials
- Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
- Gather all your ingredients and ensure everything is measured and ready to go.
2. Make the Chocolate Batter
Bloom the Cocoa Powder
- In a heatproof bowl, whisk together the cocoa powder and baking soda.
- Carefully pour in the boiling water and whisk until smooth and bubbly. This step, called “blooming,” enhances the cocoa’s flavor. Let the mixture cool for 5 minutes.
Combine Wet Ingredients
- In a large mixing bowl, use an electric mixer to blend the melted butter, vegetable oil, sugar, vanilla extract, and salt until smooth.
- Add the egg and egg yolk, mixing until fully incorporated.
Mix It All Together
- Slowly mix in the cooled cocoa mixture and the heavy cream.
- Gradually add the flour, mixing until just combined. Avoid overmixing to keep the cupcakes light and tender.
3. Bake the Cupcakes
- Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
- Bake for 17–20 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
Making the Fudge-Like Chocolate Buttercream Frosting
- In the bowl of a stand mixer fitted with a paddle attachment, cream the butter until light and fluffy. This step ensures a smooth frosting.
- Add the powdered sugar, cocoa powder, and vanilla extract, and mix on low speed until combined.
- Gradually add the heavy cream, one tablespoon at a time, mixing until the frosting is light, fluffy, and spreadable.
Assembling Your Chocolate Cupcakes
Once your cupcakes have cooled completely, it’s time for the fun part: decorating!
- Use a piping bag fitted with a star tip to pipe the buttercream frosting onto each cupcake.
- For a simpler approach, spread the frosting on with an offset spatula.
- Garnish with chocolate shavings, sprinkles, or a drizzle of melted chocolate for a final touch.
Tips for the Best Chocolate Cupcakes
- Measure Accurately: Use the scoop-and-level method for dry ingredients to avoid dense cupcakes.
- Use Fresh Ingredients: Baking soda, in particular, loses its potency over time. Check the expiration date!
- Chill the Frosting if Needed: If your kitchen is warm, refrigerate the frosting for 15 minutes before piping.
- Don’t Overbake: Keep a close eye on the cupcakes during the last few minutes of baking.
Customizing Your Cupcakes
- Double Chocolate: Fold in mini chocolate chips for an extra burst of chocolate in every bite.
- Flavor Additions: A teaspoon of espresso powder can deepen the chocolate flavor, while orange zest adds a citrusy twist.
- Filled Cupcakes: Hollow out the center and add a filling like caramel, peanut butter, or fruit jam before frosting.

How to Store and Freeze Chocolate Cupcakes
- At Room Temperature: Store frosted cupcakes in an airtight container for up to 2 days.
- In the Refrigerator: For longer storage, keep them in the fridge for up to 5 days. Let them come to room temperature before serving.
- Freezing: Freeze unfrosted cupcakes in an airtight container for up to 3 months. Thaw overnight in the fridge, then frost before serving.
