I love any combination of mint with chocolate - chocolate mint oreos, junior mints, after eights, mint nanaimo bars.....I could go on, but if your mouth is watering you might want to try this icing with a brownie too
1 cup butter
1 tsp. peppermint extract
2 tbsp. whipping cream
Beat the sugar and softened butter for 4 minutes. Add the mint extract and cream and beat for 1 minute.
If you like, add a few drops of green food colouring to tint the icing. I added a wee bit more whipping cream to make the icing more spreadable. If mint is not your thing, you could easily substitute maple or orange extract to suit your taste buds.
