Place the mini marshmallows on a sheet pan and stick under the broiler until lightly golden brown and toasted. This goes quickly, in a matter of about 30 seconds, so watch them carefully. Place 2 tsp. milk, the malted milk powder, and the marshmallow creme in a blender. Blend for 30 seconds until everything has dissolved and mixed together. Add the ice cream and half the marshmallows, and blend until mixed. Serve with the remaining toasted marshmallows on top.
