Ingredients

For the cupcakes:

  • 1 cup all-purpose flour

  • 1/2 cup unsweetened cocoa powder

  • 1 teaspoon baking powder

  • 1/2 teaspoon baking soda

  • 1/2 teaspoon salt

  • 1 cup granulated sugar

  • 1/2 cup vegetable oil

  • 2 large eggs

  • 1 teaspoon vanilla extract

  • 1/2 cup buttermilk

  • 1/2 cup hot water

For the chocolate buttercream:

  • 1 cup unsalted butter, softened

  • 3 cups powdered sugar

  • 1/2 cup unsweetened cocoa powder

  • 2-3 tablespoons milk

  • 1 teaspoon vanilla extract

  • Chocolate sprinkles for garnish


Instructions

  • Preheat oven to 350°F (175°C) and line a cupcake pan with paper liners.

  • In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, and sugar.

  • Add in the oil, eggs, and vanilla extract and mix until combined.

  • Gradually mix in the buttermilk, followed by the hot water, stirring until the batter is smooth.

  • Fill each cupcake liner about two-thirds full with batter.

  • Bake for 18–20 minutes or until a toothpick inserted into the center comes out clean.

  • Let the cupcakes cool completely before frosting.

  • For the buttercream, beat the softened butter until creamy.

  • Sift together the powdered sugar and cocoa powder, then gradually add to the butter, alternating with the milk and vanilla extract until fluffy and smooth.

  • Pipe the buttercream onto the cooled cupcakes and garnish with chocolate sprinkles.


Notes

  • Use high-quality cocoa powder for a richer chocolate flavor.

  • Add a little extra milk if the buttercream is too stiff for piping.

  • Cupcakes can be made a day ahead and frosted the next day for easier party prep.
