I so enjoyed the sweet potato Fauschnauts that I decided to try it again. I didn't have time to fill them, so I had to come up with something different. We had some caramel left over from a bread pudding. This was special caramel, made with brown butter.
I am definitely convinced that brown butter greatly improves anything. I decided to go with the theme, and brown some more butter. I let it cool and then beat the brown butter with the caramel to make the frosting.
This was a DELICIOUS frosting: the nuttiness of brown butter, the richness of caramel, and the slightness of salt. It paired perfectly with the subtle sweet potato flavor, even better than the cinnamon custard filled.
P.S. I encourage everyone to put brown butter in everything.
