Apple Cider Cupcakes with a Caramel Frosting

These were a hit at the Thanksgiving table!  The cake is more like a pound cake and could be made as either a cake or cupcakes.  The caramel frosting was amazing!

Cupcakes:

Ingredients:
2 eggs, at room temperature
1 2/3 cup flour
1 cup pasturized apple cider
2/3 cup sugar
1/2 cup butter, at room temperature
2 teaspoons baking powder
1 teaspoon cinnamon
1/2 teaspoon salt

Preheat oven to 350. Line 12 cupcake wells.  In a large bowl, cream together butter and sugar. Add eggs, one at a time, beating well after each addition. Sift together flour, baking powder, cinnamon and salt. Add 1/3 of the flour mixture to the butter/sugar mixture, then 1/2 of the cider, and repeat, ending with the last of the flour and mixing only until incorporated. Pour into prepared cupcake pan, filling each cup 3/4 way full. Bake 20 minutes or until a toothpick inserted in the center of the center cupcake comes out clean.
Cool thoroughly, then frost.

Frosting:
Ingredients:
1/2 cup butter
1 cup packed brown sugar
1/4 teaspoon salt
6 tablespoons milk
3 cups sifted confectioners' sugar 

Melt butter in a saucepan, stir in the brown sugar and the salt. Bring to a boil and boil for 2 minutes, stirring constantly. Remove from heat and add the milk, stirring all the while.  Return to heat and bring to a boil again. Remove from heat and allow to cool until lukewarm (approximately 20 to 25 minutes). Stir in the confectioners' sugar and beat until smooth and cool enough to spread. You might need to add a few drops of milk if frosting gets too stiff.
