This 3-ingredient, no-cook summer treat is the perfect dessert when it's too hot to turn on the stove (or oven). The crushed chocolate sandwich cookies form a firm yet moist crust when mixed with store-bought fudge topping and put in the freezer to firm up for several hours. Mint chocolate chip ice cream is the perfect filling to make an impressive treat without the fuss of a "from-scratch" dessert. The best part is, you can experiment with other flavors using the same construct (think chocolate-peanut butter, caramel-pretzel, and more). Tip: To easily cut bars, run knife under hot water just before slicing.
