  • Total Time: 10 minutes
  • Yield: 2 cups 1x

Ingredients

Units Scale
  • 2 tbsp instant espresso powder
  • 2 tbsp heavy cream, room temperature
  • 8 oz mascarpone cheese, room temperature
  • 8 oz butter, unsalted, room temperature
  • 1/4 tsp salt
  • 1-2 cups powdered sweetener (depending on how sweet you like your buttercream)

Instructions

  1. In a small bowl, whisk together the heavy cream and espresso powder until the espresso powder dissolves.
  2. In the bowl of a stand mixer fitted with a paddle attachment, beat together the mascarpone cheese, butter, salt, and espresso heavy cream together on medium speed for 5 minutes. Scrape down the bowl at the halfway mark.
  3. With the mixer running on medium speed, add the powdered sugar 1/4 cup at a time until you have incorporated 1 cup.  Stop the mixer, scrape down the bowl, and taste your buttercream. Continue adding sugar slowly until it is at the sweetness you prefer.
  4. Use immediately or place it in an airtight container and store it in the fridge for up to 1 week*

Notes

* If you refrigerate the buttercream, it will harden due to the butter.  Simply allow the frosting to come to room temperature and then whip it again and medium-speed until light and fluffy
