Ingredients

2 sticks (8 ounces) butter
3 cups salted pretzels, finely crushed
1 cup plus 6 tablespoons sugar
Two 8-ounce packages cream cheese, softened
Grated peel of 3 limes, plus 1/2 cup lime juice
2 tablespoons white rum
3 tablespoons finely chopped fresh mint, plus sprigs for garnish
2 cups heavy cream

Directions

1. In a medium skillet, melt the butter over medium-low heat. Stir in the pretzels and 2 tablespoons sugar and cook until lightly toasted, about 3 minutes. Transfer to a bowl to cool slightly.



2. Press about 2 tablespoons into the bottom of each cup of a 12-cup muffin pan. Freeze for 30 minutes.
3. Meanwhile, using an electric mixer, beat the cream cheese on medium speed, scraping down the sides of the bowl, until fluffy, 2 to 3 minutes.
4. Mix in the remaining 1 1/4 cups sugar on low speed, then gradually mix in the lime peel, lime juice, rum and chopped mint.
5. In a separate bowl, beat the heavy cream until stiff peaks form. Fold into the cream cheese mixture.*



6. Divide the cream cheese mixture evenly among the muffin cups; smooth the tops. Cover with plastic wrap and freeze for at least 8 hours or overnight.
7. To serve, run a wet knife around each cake, then invert the pan onto a clean work surface. Set each cake upright and top with a mint sprig.

Serves 12.
