BROWN BUTTER CREAM CHEESE FROSTING 🤎🧈 brown butter BROWN BUTTER CREAM CHEESE FROSTING 🤎🧈 brown butter is the KEY to making cream cheese frosting even better! You get the tang of cream cheese but with rich, nutty caramelized notes of brown butter and it’s HEAVENLY on any Fall cake 🙌🏼 I paired with my carrot cake recipe here but it’s also incredible with spice cake, pumpkin cake, chocolate cake, and more! 

Full recipe + all my favorite cake pairing suggestions in my bio and here: https://sugarandsparrow.com/brown-butter-cream-cheese-frosting/

BROWN BUTTER CREAM CHEESE FROSTING 
YIELD: 3.5 Cups  
 
INGREDIENTS 
1/2 Cup (113g) unsalted butter 
8 Oz (226g) full-fat brick-style cream cheese, room temperature NOT the spread 
4 Cups (480g) powdered sugar 
1 tsp pure vanilla extract 
pinch of salt, or to taste 
 
INSTRUCTIONS 
1. Brown the butter: Add the butter into a large frying pan and cook over medium heat until the butter melts, stirring occasionally. Continue cooking for 3-5 minutes while stirring constantly. First it will foam, then bubble as little white particles of milk solids separate, then the white specks will caramelize and turn medium-brown and smell deliciously nutty. Remove from heat, transfer to a glass container, and cool until it re-solidifies and is the consistency of softened butter (about 45 minutes in fridge).  
2. Add the cooled brown butter into the bowl of your stand mixer fitted with a paddle attachment and add the cream cheese. Mix on medium-high until fluffy and light in color, 5 min, scraping down the bowl and paddle as needed. 
3. Turn the mixer to low speed and add the powdered sugar a few cups at a time, scraping down the bowl and paddle after mixing in each addition. Add the vanilla and salt and continue mixing on low speed until smooth and uniform.
