1 box white cake mix
1/2 cup butter, softened at room temperature (melting it makes the cookies texture tough)
2 large eggs
1 tablespoon grated lime zest (don't skip this, it is worth it)
1 1/4 cups which chocolate chips
3 cups powdered sugar
2 teaspoons grated lime zest (again, do it; really)
5-6 tablespoons FRESH lime juice (don't open a bottle, squeeze a lime, please)
Preheat oven to 350°.
Cover cookie sheets with parchment.
With mixer, combine cake mix, softened butter, eggs and 1 tablespoon lime zest until blended and smooth.
Stir in remaining white chocolate chips with a wooden spoon or spatula.
Drop dough by teaspoonfuls, 2 inches apart, onto prepared cookie sheets.
Bake 10-13 minutes or until set at edges and just barely set at center.
Cool 1 minute on sheets; transfer to wire racks and cool completely.
Combine powdered sugar, 2 teaspoons lime zest and enough FRESH lime juice make icing just thin enough to drizzle off fork.
Drizzle icing over cooled cookies. (4 dozen cookies)
