I looked at a few different eggnog recipes & came to the decision that the two ingredients I needed to get the flavor right were rum & nutmeg. I used eggnog in the cake batter instead of milk to up the flavor even more. The cupcake itself came out really tasty with a great texture but its really the frosting that makes this taste & smell like eggnog to me. These are quite rich so I'm glad I made mini cupcakes this time around, just the perfect little bite. They certainly seemed to be a big hit last night.
1 c (2 sticks) unsalted butter, at room temperature
1 1/3 c + 3 T sugar
2 t rum
1/8 t vanilla
1 1/3 t baking powder
2/3 t salt
2 c all-purpose flour
2/3 c eggnog
5 egg whites
Preheat oven to 350 F. Prepare 48 mini cupcake tins or 18 regular.
In a mixing bowl cream the butter & 1 1/3 cups of sugar together until light & fluffy. Beat in the rum & vanilla. Add the baking powder, salt & 2/3 cup flour, beat until combined. Beat in 1/3 cup eggnog. Then beat in another 2/3 cup flour, followed by the rest of the eggnog & then the rest of the flour.
In another bowl beat the egg whites until foamy. Add in the remaining 3 tablespoons of sugar. Beat on high speed until stiff peaks form. Gently fold 1/3 of the egg whites into the batter until completely combined then fold in the remaining egg whites.
Divide the batter between the cupcake tins, filling each one 2/3 full. Bake 15 minutes for mini cupcakes or 22 for regular. A toothpick inserted into the center should come out clean.
Cool completely on a rack.

You can substitute run extract for the rum but I think it has a stronger flavor.
Update 12/28/08: There was originally a typo in this recipe & I wrote baking soda instead of powder. Powder is correct. Thanks to Danya for catching it.
I also had the wrong amount of sugar (I must have been drinking the rum when I wrote this!). Its correct now.
