If you prefer to use the microwave to melt the marshmallow mixture, heat butter and marshmallows on HIGH for 3 minutes, stirring after 2 minutes. Stir until smooth.
We ended up with 9 Christmas tree treats from our batch. However, depending on the size of your cookie cutter, the number of treats you end up with could vary.
You could skip the cookie cutter all together and simply cut the treats into long triangles.
