2 tablespoons peanut butter
2 tablespoons marshmallow topping
1 cup chocolate ice cream
Spread all crackers with peanut butter, then marshmallow topping. Top 4 with 1/4 cup ice cream each. Cover with remaining crackers, spread side down. Gently squeeze sandwiches until ice cream spreads to edge of cookies.
Serve immediately or wrap in plastic wrap and freeze up to 3 days.
