  1. These were yummy and super easy to make. Followed the recipe exactly – it took 22 minutes to bake. Perfect for a picnic as you don’t have to worry about frosting getting all over the place. And the cookie isn’t too sweet which is good because you’re adding M&M’s. I could see adding different candy as well like toffee bits or Reece’s pieces. I’ll definitely be making these again!
