Preheat the oven to 350 F (177C) and line cupcake tins with cupcakes liners.
In a large mixing bowl, sift together dry ingredients: all-purpose flour, expresso powder, unsweetened cocoa powder, baking powder and pinch of salt.
In a second mixing bowl, mix the oil, granulated sugar, fresh 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 the cupcakes for 15-18 min.
Cool 5 minutes in the pan then transfer to a rack to cool completely to room temperature before filling and frosting.
