What you need:
Directions:
1. Cream together butter and sugars until fluffy.
2. Add eggs and vanilla and mix until combined.
3. Mix together your dry ingredients (minus the marshmallows) in a separate bowl and then add into the wet ingredients. Mix well.
4. Drop dough by the teaspoon onto a greased cookie sheet or one lined with parchment paper (which I prefer).
5. Bake in a preheated 350-degree oven for 10 minutes or so. They should be just a little firm.
6. Remove cookies from oven and immediately top with marshmallows. Let them stand on the sheet for a few minutes and then remove to a wire rack.
