Expert recommendation: Use extra Fruity Pebbles. You can never have enough.
Ingredients (makes 3 sandwiches)
3 tbsp butter
10 oz. bag of marshmallows
6 cup fruity pebble cereal
1 pint vanilla ice cream
Grease Medium Sheet Pan
In a large saucepan over low heat, melt butter. Once completely melted, add marshmallows and stir until completely melted and smooth. Remove from heat and quickly stir in Fruity Pebbles until well coated.
Using wax paper or spatula, press mixture into sheet pan until about 1/2″ thick. Let cool at least 20 minutes.
Using a cookie or biscuit cutter, punch out 8 circles or squares. Place 1 big scoop of vanilla ice cream in between two Fruity Pebble circles and press down. Repeat to make 3 more sandwiches.
Freeze until ready to serve.
