Preheat the oven to 350 degrees and place liners in a cupcake pan, set aside.
In the bowl of a stand mixer, combine the sugar, sour cream, oil, egg, baking powder, and salt. Mix until well combined.
1 1 /2 cups sugar, 1 egg, ¾ cup sour cream, ¼ cup oil, 1 tsp baking powder, ½ tsp salt
Add in the cocoa powder, coffee, vanilla and flour. Mix well - stopping the mixer, scraping the sides and mixing again until smooth.
½ cup cocoa powder, ½ cup freshly brewed coffee, 1 tsp vanilla, 2 cups flour
Fill each cupcake liner until about ⅔ full. Bake in preheated oven for 16-18 minutes or until a toothpick inserted in the center comes out clean. Allow to cool completely before decorating.
