Store-bought pound cake and ice cream keep these mini desserts simple. All you have to do is beat the egg whites until light and airy for the delicious meringue topping.
Using a cookie cutter or knife, trim 4 slices of pound cake to snugly fit bottoms of four 6-ounce ovenproof custard cups. Divide softened ice cream among lined cups.
In a mixing bowl, beat egg whites with pinch of salt to soft peaks. Gradually add sugar, beating until stiff and glossy; mound over ice cream. Freeze 1 hour or up to 1 week.
To serve, preheat oven to 450 degrees. Transfer cups to a baking sheet; let sit 10 minutes. Bake until lightly browned (watch carefully), 2 to 4 minutes.
