An impressive dessert can contain just three ingredients. Change up the flavors with different bars, cookies, and ice creams.

Pistachio-Brownie Ice Cream Dessert

Line a 9x5-inch loaf pan with parchment paper, leaving about 1-inch of parchment extending over the edges of the pan. Spoon ice cream into prepared pan, spreading evenly. Place a single layer of brownies, frosting sides down on top of ice cream, trimming edges to fit. Cover and freeze for 8 hours or up to 24 hours.

To serve, use parchment to lift uncut dessert out of pan. Peel off parchment and slice dessert. Garnish with chopped pistachios, if desired.
