How To Make Thaw the biscuits overnight in the refrigerator. Preheat waffle iron to low. Roll out each biscuit until it is 4 inches across. Place the biscuit in the center of the waffle iron and press to close. Cook for 10 minutes. Set aside to cool while the others cook. Once all the waffles are cooked, line a baking pan with parchment paper. Place the waffles on the prepared pan and freeze for 15 min. Let the ice cream sit out for 10 min or until softened. Scoop 2 scoops of ice cream onto one waffle and top with a second waffle to form a sandwich. Roll the exposed edge of the sandwich in the sprinkles and return to the pan. Repeat with remaining waffles. Place the sandwiches in the freezer 1-2 hours or until frozen. Once frozen, enjoy right away or place in an airtight container and freeze for later!
