Making the Chocolate Cupcakes

- Cream butter and sugar: In a separate bowl, beat butter, granulated sugar, and brown sugar until light and fluffy.
- Add eggs and vanilla: Mix in eggs one at a time, then add vanilla extract.
- Incorporate buttermilk and coffee: Alternate adding dry ingredients with buttermilk, starting and ending with the dry ingredients. Stir in hot coffee at the end.
- Bake: Fill cupcake liners 3/4 full and bake for 18-20 minutes. Cool completely before frosting.

Making the Mocha Buttercream Frosting
