I used it for some strawberry-banana muffins and it was to die for! Obvi, to avoid eating it all in one day, I brought the treats into the newsroom for some help.
Here's the recipe:
(Makes 2 1/2 cups)
1/2 cup (1 stick) butter, room temperature
8 ounces cream cheese
1 cup packed light-brown sugar
With an electric mixer on medium-high speed, beat butter, cream cheese, and brown sugar until combined and smooth. Use immediately or store in an air-tight container in the refrigerator.
