Recipe adapted from Confections of a Foodie Bride
1 box white cake mix (I used Duncan Hines)
7 1/2 ounces margarita mix
2 ounces tequila
1/2 ounce orange juice
3 large egg whites
2 T vegetable oil
Zest of 1 lime
Preheat oven to 350 degrees and line 24 muffin tins with paper liners or spray with baking spray. Mix together margarita mix, tequila and orange juice in a large measuring cup. Add cake mix to mixing bowl and add egge whites, oil, lime zest and tequila mix. Beat on low speed for about 30 seconds until dry ingredients are incorporated and then beat on medium high speed for 2 minutes. Spoon batter evenly into muffin cups, filling about 2/3 of the way full. Bake for 20-25 minutes until a toothpick inserted in the center cupcake comes out clean. Cool about 5 minutes in the pan and then cool completely on wire racks.
Lime Cream Cheese Icing
8 oz cream cheese, room temperature
1/2 cup unsalted butter, room temperature
2-3 T lime juice
4 cups powdered sugar
1 tsp lime zest
3-4 drops green food coloring
Beat cream cheese and butter on medium high speed until smooth and fluffy, about 3 minutes. Add 2 T lime juice and lime zest and beat until combined. Add powdered sugar 1 cup at a time, beating on low speed until incorporated. Add more lime juice if necessary. Add food coloring a couple drops at a time and beat on medium high speed until desired color is reached and icing is smooth. Pipe onto cooled cupcakes as desired.
Lime wedges, straws, and sprinkles all make festive garnishes. Refrigerate cupcakes in an airtight container if not serving immediately and bring to room temperature a couple hours prior to serving.
