In a small bowl, prepare the espresso by mixing 2 tablespoons (30 ml) instant espresso powder with 1 tablespoon (15 ml) warm water until well combined.
Mix in the sifted powdered sugar ½ cup (60 g) at a time, beating each addition of powdered sugar until incorporated. Scrape down sides of mixing bowl as needed.
Once all the sugar has been added, beat the buttercream on medium - high for 30 - 60 seconds or until the coffee butter cream is to your desired consistency.
