Instructions
Brown the Butter:
Place butter in a saucepan over medium heat, stirring occasionally. The butter will begin to crackle, then start to foam. Once it starts to foam, it usually takes about 2-3 more minutes. Golden specks will start to come up in the foam and it will begin to smell nutty and delicious, once you start to see golden specks in the foam, it should take about 30 more seconds. See photos above for a visual. Remove from heat and place in a dish with a nice wide bottom so it'll cool quickly (I like to use a 9x13 baking dish) and place somewhere away from the warm stove.
Make the frosting:
Once the browned butter has cooled to room temperature, make the frosting. Beat the softened cream cheese on medium speed with an electric mixer until perfectly smooth, about 1-2 minutes. Add the brown butter and beat until well combined. Add the vanilla and brown sugar and beat about 2 minutes, until the brown sugar has mostly dissolved. Add the powdered sugar and mix until smooth. To use for piping, refrigerate for 30 minutes first for best results.

Notes
Cream cheese that is nice and soft is smoother and will make your frosting less lumpy. We highly recommend using cream cheese that is fully softened.
This makes enough to frost about 16-24 cupcakes, depending how much you use.
Store leftovers in the refrigerator in an airtight container for up to 2 weeks. Allow to warm on the counter for 15 or so minutes and give it a little stir before use after storing.
