Instructions:
- Preheat oven to 350°F (175°C). Line cupcake tin with cupcake liners.
- Whisk together flour, cocoa powder, baking powder, baking soda, and salt in a medium bowl.
- In a separate large bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Beat in the eggs one at a time, then stir in the vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix!
- Gradually stir in the hot coffee until the batter is smooth. The batter will be thin.
- Fill cupcake liners about 2/3 full.
- Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cupcakes cool in the tin for a few minutes, then transfer them to a wire rack to cool completely before frosting.
- In a large bowl, beat the softened butter until smooth and creamy.
- Gradually add the powdered sugar and cocoa powder, alternating with the milk and vanilla extract, until the frosting is smooth and creamy. Add a pinch of salt.
- Once the cupcakes are completely cool, frost them with the chocolate fudge frosting. Garnish with sprinkles if desired.
