This chocolate cupcake recipe is packed with chocolate flavor. Moist dark chocolate cupcakes swirled with chocolate buttercream frosting. So simple and so delicious!

Equipment

  • Stand mixer or electric hand mixer

Ingredients 

Chocolate Cupcakes

  • ¼ cup semisweet or dark chocolate chips
  • ¼ cup dark cocoa powder
  • ¾ cup boiling water
  • ¾ cup all-purpose flour
  • ¾ cup granulated sugar
  • ½ tsp baking soda
  • ½ tsp salt
  • cup vegetable oil
  • 2 eggs
  • 2 tsp vanilla extract

Chocolate Buttercream Frosting

  • 1 cup unsalted butter room temperature
  • 3 cups powdered sugar
  • cup dark cocoa powder
  • 1 tsp vanilla extract
  • ¼ tsp salt
  • 2 tbsp heavy cream

Instructions

Chocolate Cupcakes

  • Preheat oven to 350° F. Line a cupcake pan with 12 cupcake liners.
  • In a small bowl or a glass liquid measuring cup, stir together chocolate chips, cocoa powder, and boiling water until the cocoa powder is dissolved. Set aside to cool slightly.
  • In a mixing bowl, combine all-purpose flour, granulated sugar, baking soda, and salt. Whisk to combine.
  • Pour the chocolate mixture into the dry ingredients and whisk until combined.
  • Add vegetable oil, eggs, and vanilla extract. Whisk until combined and smooth.
  • Use a large cookie scoop to portion the cupcake batter into the cupcake liners, approximately ¾ full.
  • Bake for 20 minutes or until the tops of the cupcakes bounce back slightly when touched.
  • Remove from the oven and cool in the pan for 5 minutes. Transfer the cupcakes to a wire cooling rack to cool completely.

Chocolate Buttercream Frosting

  • In a large mixing bowl or the bowl of a stand mixer fitted with a whisk attachment, add in room temperature butter. Whip the butter for 5 minutes on medium-high speed, scraping down the sides occasionally.
  • Add the powdered sugar and mix on the lowest speed setting until fully combined.
  • Add in dark cocoa powder and continue to mix on low until combined.
  • Add in vanilla extract and salt. Drizzle in heavy cream.
  • Turn the mixer on high and whip for an additional 2-3 minutes. Scrape the sides of the bowl occasionally to ensure the frosting is well mixed.
  • Use a piping bag fitted with a piping tip (my favorite is Wilton 1M tip) to pipe buttercream onto the cooled cupcakes.
