Spray a mini muffin tray (with room for 12 muffins) with non-stick cooking spray.
Combine graham cracker crumbs, butter and sugar in a bowl and mix until moist.
Spoon one tablespoon of the crust mixture into each of the 12 mini muffin tins. Press hard with an object such as a shot glass to make it firm. Be sure to make it as firm as possible or it may fall apart when removing it from the muffin tins.
Melt 3/4 cup of chocolate chips in the microwave. Start by setting it for 90 seconds, stir, then microwave in 30 second increments until smooth and creamy.
Spoon 1 tablespoon of melted chocolate into each muffin tin.
Place in freezer until chocolate is hardened, approximately 15 minutes.
Add 1/2 tablespoon of marshmallow fluff to each muffin tin. Return to freezer.
When ready to serve, pop the crust layers out of the muffin tins by sliding a knife down one side. They should pop right out.
Top with a small scoop of Blue Bunny Vanilla Ice Cream (or any other Blue Bunny flavor you'd like).
Top with a dollop of Reddi-wip and chocolate sprinkles. Serve immediately.
