1. Preheat oven to 375 degrees and prep a 9X9, 8X8, or circle pan by greasing it or lining it with parchment paper. (If you want to only only one box of cookie mix then use a small loaf pan!)

2. Combine cookie mix with butter and eggs (according to the box instructions.)

3. Use half of the dough to press into your prepared pan. Spread marshmallows over the top and then cover with the rest of the dough. See video!

4. Bake for 20-25 minutes depending on how well done you want your cookies!

5. Serve warm with ice cream or let cool for the perfect picnic treat!
