Preheat the oven to 350oF (177oC) and line cupcake tins with cupcake liners.
In a large mixing bowl, sift together dry ingredients: all-purpose flour, espresso powder, unsweetened cocoa powder, baking powder, and a pinch of salt.
In a second mixing bowl, mix the oil, granulated sugar, freshly brewed coffee, vinegar, and vanilla extract.
Pour wet ingredients over dry ingredients and whisk just until the ingredients come together.
Fill each cupcake liner 2/3 full.
Bake at 350oF (177oC) for 15-18 minutes.
Cool cupcakes for 5 minutes in the pan, then transfer to a rack to cool completely to room temperature before filling and frosting.
Notes
Use a kitchen scale to measure all ingredients. Cool the cupcakes completely before decorating with cream.
