Step 1

Place 1/2 cup of butter in a skillet on medium heat. Melt the butter and then allow it to continue to simmer on medium heat. The melted butter will start to bubble and a foam will appear and then brown crystals will begin to form.  Stir every 30 seconds for about 6-7 minutes.  It will be golden brown, with yummy bits of brown butter goodness floating in the melted butter. When you reach this stage take the brown butter off the heat and pour it into a glass bowl to cool.

Step 2

Allow the brown butter to cool but not solidify.  Leave it on the counter, not the refrigerator.

Step 3

Add the softened butter and the powdered sugar to a mixing bowl.

Step 4

Now add the brown butter to the mixing bowl.  Use a spatula and make sure you get every bit of the yummy brown butter solids into the mixing bowl.

Step 5

Start your mixer (or electric beater) on the lowest setting.  Keep on low until the butter and sugar are incorporated and then kick your mixer up to medium high.

Step 6

Add 1 tablespoon of milk and mix until it is the frosting right consistency.  Continue to add milk a teaspoon at a time until it is the right consistency.
