Best Chocolate Cupcakes
Description
The Best Chocolate Cupcakes recipe features a batter blending chopped bittersweet baking chocolate, Dutch-process cocoa powder, and instant espresso powder dissolved in boiling water, which enhances chocolate notes without a coffee taste. Flour, sugars, salt, and baking soda are mixed separately, then combined with sour cream, vegetable oil, eggs, vinegar, and vanilla to create a moist, tender cupcake batter without overmixing.
After baking at 350°F for about 17-18 minutes, the cupcakes develop a firm yet tender structure. Cooling prevents crumbling when frosted.
The frosting combines cold heavy cream melted with finely chopped semisweet chocolate, and softened unsalted butter mixed with powdered sugar, Dutch-process cocoa, vanilla, and salt. This results in a silky, rich frosting with balanced cocoa bitterness and sweetness, perfect for icing the cupcakes.
The recipe yields about a dozen cupcakes depending on pan size. Alternatives include substituting strong brewed coffee for espresso powder with water for flavor variation and omitting vinegar if using natural cocoa powder to maintain leavening.
Ingredients
For the cupcakes:
- 5 ounces bittersweet baking chocolate finely chopped
- 1/3 cup Dutch-process cocoa powder
- 1 teaspoon instant espresso powder
- 1/2 cup water boiling
- 3/4 cup all-purpose flour 95 grams
- 1/2 cup granulated sugar 100 grams
- 1/2 cup light brown sugar 100 grams, packed
- 1/2 teaspoon salt fine
- 1/2 teaspoon baking soda
- 1/2 cup sour cream at room temperature, or plain full fat yogurt
- 1/4 cup vegetable oil
- 2 egg at room temperature, large eggs plus one egg yolk
- 2 teaspoons white vinegar
- 1 teaspoon vanilla extract
For the frosting:
- 1/2 cup heavy cream cold
- 4 ounces semisweet chocolate don't use chocolate chips, 113 grams, finely chopped
- 3 unsalted butter at a cool room temperature, 340 grams, sticks
- 2 cups powdered sugar sifted (preferably organic, 250 grams
- 1 cup Dutch process cocoa powder sifted
- 2 teaspoons vanilla extract
- 1/4 teaspoon salt fine sea salt
Instructions
Make the cupcakes:
- In a medium heatproof bowl, combine the chocolate, cocoa powder, and espresso powder. Pour hot water over mixture. Cover and let stand for 5 minutes. Whisk mixture gently until smooth, then set aside to cool.
- Meanwhile, preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners.
- In a small bowl, whisk together the flour, sugars, salt, and baking soda.
- Whisk sour cream, oil, eggs, egg yolk, vinegar, and vanilla into the cooled chocolate mixture until smooth, scraping down the sides and bottom of the bowl as you mix. Stir in the flour mixture until smooth, being careful not to overmix.
- Using a spring-loaded scoop, divide the batter evenly among prepared muffin cups until 3/4 full. Bake until cupcakes are set and firm to the touch, about 17 to 18 minutes.
- Let cupcakes cool in pan on a wire rack for 10 minutes before removing from pan to cool completely, about 1 hour. Cupcakes can be stored in an airtight container at room temperature for up to 1 day.
Make the frosting:
- In a small saucepan, bring the cream to a simmer. Remove from heat and add the chopped chocolate. Let stand for a few minutes before stirring until smooth. Set aside and cool to approximately 75°F or until thickened but still pourable.
- In the bowl of a stand mixer fitted with the paddle attachment, add the butter, powdered sugar, cocoa, vanilla, and salt. Mix on low speed until well blended and then increase the speed to medium and beat for another 3 minutes, or until very well blended, scraping down the bowl as needed.
- Reduce speed to medium-low and add the cooled chocolate cream mixture. Continue beating until the frosting has lightened in color and texture, about 2 minutes more, scraping down the bowl as needed.
- Frosting can be made 1 day ahead of time and stored in an airtight container in the refrigerator. Warm frosting in the microwave for 5 to 10 seconds and stir until creamy again before frosting cupcakes.
- Frosting can also be transferred to a ziptop bag and frozen for up to 1 month. Defrost in the fridge overnight then rewhip in the stand mixer until light and smooth.
Notes
- Cupcake yield depends on muffin tin size; smaller cavities may require two pans for 15 cupcakes total.
- Use strong brewed coffee instead of espresso powder and hot water to enhance chocolate flavor.
- If using natural cocoa powder, omit vinegar from the batter to maintain proper rising.
- For smoother frosting, use organic powdered sugar made with tapioca starch rather than cornstarch.
