For the cake, you will need:
* 1 box white cake mix
* 1 cup seltzer, unflavored
* 1/3 cup vegetable oil
*1 teaspoon rum extract
*1/2 teaspoon mint extract
*1/4 cup water
* 3 tablespoons chopped fresh mint leaves (I forgot to buy these, so I used mint extract)
* 1/2 lime, zested
* 3 egg whites
For the glaze, you will need:
* 1/2 cup butter
* 1/2 cup water
* 1 cup granulated sugar
* Rum or 2 teaspoons rum extract (I went heavy here and used 1 tablespoon of Myer's Dark Rum)
1. Preheat oven to 350°F and place liners in 2 cupcake pans.
2. In a mixing bowl, beat cake ingredients on low speed 30 seconds followed by 2 minutes at medium speed minutes, scraping bowl occasionally.
3. Place batter into cupcake liners and bake 25 minutes (or until toothpick inserted in center comes out clean) Cool 15 minutes before applying the glaze.
4. While the cupcakes are cooking, melt the butter in a sauce pan. Over high heat, add the rum and remaining ingredients. Once the mixture reaches a boil, reduce heat to medium and continue cooking until the mixture has thickened.
5. Poke the top of the cupcakes a few times with a fork. Pour glaze slowly over cupcakes. Allow glazed cupcakes to cool completely, about one hour.
6. Top with frosting and garnish. I used the frosting recipe below, and I added a small lime wedge along with a paper straw.
I frosted these cupcakes with a recipe from Mrs. Regueiro's Plate.
For the frosting, you will need:
*8 oz cream cheese, room temperature
* 3 cups powdered sugar
*2 teaspoons dark rum
*1/2 stick (4 tablespoons) unsalted butter, room temperature
*zest of one lime
*1 tablespoon lime juice
1. In a mixing bowl, cream the butter and cream cheese together for about two minutes. Add the sugar one cup at a time, and mix to combine after every addition. Mix in the lime zest, lime juice, and rum until incorporated.
2. Frost your cupcakes!
