| 1 | cup butter |
| 1 | cup firmly packed light brown sugar |
| 1 | cup firmly packed dark brown sugar |
| ½ | cup whipping cream |
| 4 | cups powdered sugar, sifted |
| 2 | t double strength vanilla |
Melt the butter and brown sugars over low heat until dissolved, stirring constantly. Add the whipping cream and bring to a boil over medium heat, stirring constantly for about 7 minutes. This will burn easily so do not leave it unattended.
Remove from the heat. Pour into the bowl of an electric stand mixer. Gradually beat in the powdered sugar and the vanilla at medium speed with the whisk attachment. You can also use a hand mixer with the thinnest beaters. This will take about 6-10 minutes and then it will begin to thicken. If it suddenly gets too thick you may thin with 2 T of hot water. Once it starts to thicken start smoothing it on quickly. Even with your best efforts, there may be a bit of hardened icing left in the bowl—it is like candy, so enjoy it!
