Matcha Buttercream
Earthy and slightly sweet faux swiss meringue matcha buttercream. The texture is pillowy and smooth, perfect for icing cakes, cupcakes, and filling macarons!
Servings 5 cups
Ingredients
- 1 ¾ cup unsalted butter, room temperature (310g or 3 ½ sticks)
- 4 oz pasteurized egg whites, room temperature about 4 eggs
- 3 ¾ cup powdered sugar (454g)
- 2 tsp pure vanilla extract
- ¾ tsp kosher salt
- 1 tbsp + 2 tsp matcha powder (18g)
Instructions
- Let your unsalted butter and egg whites come to room temperature. Cut the butter roughly into 1 tablespoon cubes.
- In a stand mixer with a whisk attachment, add the egg whites and mix for 30 seconds on medium speed. Add the powdered sugar one cup at a time, mixing on medium speed until dissolved.
- Add the vanilla extract and salt and mix on medium speed until incorporated. Switch to the paddle attachment, turn the mixer on low and slowly add the butter 1 tablespoon at a time. It can look curdled but just keep mixing.
- Sift in the matcha powder and mix on low to incorporate. For extra silky smooth texture with less air bubbles, mix for five extra minutes with the paddle attachment on low speed.
Notes
- Flavor: SMBC is not as sweet as American buttercream. Matcha SMBC can be described as an earthy and slightly sweet flavor.
- Amounts: This recipe makes about 5 cups of frosting. You can frost and fill up to a 3 layered, 8-in cake.
- Decorating: In the pictures I show a decorated mini 4-inch matcha cake using a Ateco #22 piping tip. This is not a crusting buttercream.
- Freezing: You can make matcha buttercream ahead or store leftover frosting in the refrigerator for 1 month or the freezer for 2 months. Use good quality airtight containers to avoid freezer burn. To use, take the buttercream out ahead of time to reach room temperature. Then, mix it in a stand mixer on low speed to bring it back to life and get ride of air bubbles.
