Heat oven to 350 and line baking sheet with parchment paper or silicone baking sheet
Add your dry ingredients into a large mixing bowl and mix
Next, add your wet ingredients and stir until a smooth batter forms
Fold in Marshmallows and Chocolate Chips
Use a spoon to drop heaping tablespoon fulls of cookie dough about an inch apart on the cookie sheet. The cookies will rise and spread out some, but not significantly
Bake for approx. 12 minutes, or until the tops become golden brown and the marshmallows begin to swell and roast on the cookies
Remove from oven and allow to sit on a baking sheet for another 2-3 minutes before placing on a cooling rack
