Make the mashmallows but spread into a baking sheet instead of a 9 by 13 pan. Just spray the pan with nonstick coating such as Pam, don’t coat them in the powdered sugar mixture.
When set cut into stars with an oiled cookie cutter. I had a starfish cutter but a plain star is fine.
Don’t throw away those marshmallow scraps! Use them in hot cocoa, or make the best rocky road you’ll ever taste.
Cut into chunks and put in a bowl with some peanuts and cocoa nibs (or your choice of nut).
