Key Lime Cupcakes

I am slowly working my way through a huge bag of key limes, and these cupcakes from My madison bistro were a great way to use a few of them. I absolutely loved these cupcakes, can't say enough good things about them.  Randal  took them to work this morning and from what I hear everyone who tried them liked them also.

Cupcakes:
1 ¾ cups cake flour
½ tsp baking powder
½ tsp baking soda
½ tsp salt
1 stick unsalted butter
1 ¼ cups sugar
2 large eggs
2 ½ tbsp key lime juice
1 tbsp key lime zest
1 drop green food colouring
¾ cup buttermilk

Frosting:
1 stick unsalted butter
8 ounces cream cheese
2 ¼ cups icing sugar
1 tbsp key lime zest

Preheat oven to 350. Line a muffin tin with 12 liners.

Sift the cake flour, baking powder, baking soda, set aside.

Using a mixer beat the butter until softened. Add sugar and beat for four minutes, until fluffy. Add eggs, lime juice, zest, and food colouring and mix.

Add the flour in three additions, alternating with the buttermilk, beginning and ending with the flour.  Fill each cupcake liner 2/3 full. Bake 22-25 minutes. Cool and frost with cream cheese icing and sprinkle additional lime zest over frosting.

To make the frosting, beat the butter until softened.  Add the cream cheese and slowly add icing sugar until combined. Beat in zest.
