  • 1 3/4 cups quick oats
  • 1 1/2 cups all-purpose flour
  • 1 tsp. baking powder
  • 1/2 tsp. baking soda
  • 1/2 tsp. salt
  • 1 tsp. ground cinnamon
  • 1 cup crushed graham crackers
  • 1 cup packed light brown sugar
  • 1/4 cup Truvia Baking Blend or 1/2 cup granulated sugar
  • 1/2 cup coconut oil
  • 1 large egg
  • 3/4 cup applesauce
  • 1/2 cup semisweet chocolate chips
  • 18 large marshmallows cut in half
  • 1/2 cup Hershey's milk chocolate bar cut up


  • Preheat to 350ยบ F. Spray one or two cookie sheets with cooking spray.
  • In a medium bowl, combine oats, flour, baking powder, baking soda, salt, cinnamon, and graham crackers. Mix well with a wire whisk and set aside.
  • In a large mixing bowl, combine sugars. Then add coconut oil until blended. Now add applesauce and mix and then the egg and blend until smooth.
  • Add in the flour mixture and blend only until just combined. Add in chocolate just until incorporated. Don't overmix!
  • Drop dough by tablespoon onto prepared cookie sheets, 2 inches apart. Bake for 10 minutes and then pull cookie sheet from oven. Place a half of marshmallow on top of each cookie and then place in the oven for another 3-5 minutes.
  • (The marshmallows tend to slide off the cookies at the end of baking. I found that putting a slight indentation in the top of the cookies before baking helped keep the marshmallows from sliding off as much.)
