I tried it this afternoon (without the rum) and it was yummy. Todd thought it was a little to "spicy" for him ... whatever!
1 c butter, softened
2 c confectioners' sugar
1 c plus 2 Tbsp packed brown sugar
2 c vanilla ice cream, softened
1 1/2 tsp ground cinnamon (you could add less if you wanted)
1/2 tsp ground nutmeg
1 tsp rum extract (I used vanilla since I didn't have any rum extract lying around!)
In a large bowl, cream butter and sugars until light and fluffy. Add the ice cream, cinnamon, nutmeg and extract. Transfer to a freezer container; freeze overnight. The mix may be frozen for up to 2 months.
To prepare hot drink. Dissolve 2-4 tablespoons of rum mix in boiling water (recipe calls for 3/4 c - but I just filled the cup up), stir well. Add rum if desired.
