The Brown Butter Frosting of your Dreams

Brown butter is basically the equivalent of liquid gold in baking, it makes everything taste fancier, toastier, and just SO much better. Especially when you turn it into a thick and fluffy brown butter frosting. In this simple recipe I'm gonna show you exactly how to make nutty, caramelized brown butter and turn it into the buttercream frosting of your dreams.

Ingredients

  • 1 cup (227 g) butter, unsalted, softened to room temp
  • 3 cups (360 g) powdered sugar
  • 1 tsp (1 tsp) vanilla extract
  • 1-2 tbsp (1 tbsp) milk

Instructions
 

  • Add 1 cup of butter (2 sticks) to a light colored skillet over medium heat. Let the butter melt slowly. After about 2 minutes it will start to foam up. Stir it every 20 seconds or so.
  • The foam will subside slightly and you'll see the milk solids separate and start to sink to the bottom. Keep stirring lightly.
  • After about 5-6 minutes the milk solids will start to brown and smell super nutty. When they are an amber color, take the butter off the heat and stir again. Slowly pour the butter into a bowl scraping up all those flavorful brown bits at the bottom. Chill in the fridge for about 1 hour, or until solidified but soft and scoop-able.
  • Add the butter and 3 cups of powdered sugar to a stand mixer bowl fitted with a paddle attachment. Start to mix on low so that the sugar doesn't blow out of the bowl. Move to medium speed and cream the butter and sugar till it clumps together, about 2 minutes.
  • Move the mixer to low speed and add in the 1 tsp vanilla extract and 1-2 tbsp milk depending on the consistency that you want. I usually add 2 tbsp to keep it easy to spread.
  • Frost over cake or cupcakes!

Notes

Store the leftover frosting in a ziptop bag or in a container with a lid. If you are using it the next day you can store it at room temperature. If you're making it ahead, keep it in the fridge.
