It was a fun, slightly silly, but definitely memorable experience.

Ingredients
- 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
Instructions
-
Preheat your oven to 350º F (175°C). Prepare one or two large cookie sheets by lightly spraying them with cooking spray or lining them with parchment paper.
-
In a medium-sized bowl, combine all your dry ingredients: quick oats, all-purpose flour, baking powder, baking soda, salt, ground cinnamon, and the crushed graham crackers. Use a wire whisk to mix everything together thoroughly until well combined. Set this bowl aside.
-
In a separate, large mixing bowl, start by combining the brown sugar and Truvia Baking Blend (or granulated sugar if using). Add the coconut oil and beat until the mixture is smooth and well blended. Next, stir in the applesauce until fully incorporated, and finally, add the large egg, beating until the wet ingredients are smooth and cohesive.
-
Gradually add the reserved dry flour mixture to the wet ingredients. Mix on low speed or by hand only until the ingredients are just combined and no streaks of flour remain. Be careful not to overmix the dough, as this can lead to tough cookies. Gently fold in the semisweet chocolate chips and the cut-up Hershey’s milk chocolate bar until they are evenly distributed throughout the dough.
-
Drop rounded tablespoons of cookie dough onto your prepared cookie sheets, ensuring they are spaced about 2 inches apart to allow for spreading. Bake in the preheated oven for 10 minutes. After 10 minutes, carefully remove the cookie sheets from the oven. Quickly place one half of a marshmallow on top of each partially baked cookie. Return the cookie sheets to the oven and bake for an additional 3-5 minutes, or until the marshmallows are golden brown and perfectly gooey, and the cookies are set at the edges.
-
(Pro Tip: Marshmallows can sometimes slide off the cookies as they bake and melt. To help prevent this, I found that making a slight indentation in the center of each cookie dough ball before the initial baking step can help cradle the marshmallow and keep it in place more effectively.)
Tips for Perfect Oatmeal S’mores Cookies
- Don’t Overmix: As with most cookie recipes, overmixing the dough can develop the gluten in the flour too much, leading to tougher cookies. Mix just until combined.
- Marshmallow Placement: The tip about making a slight indentation before baking is crucial! It really helps the marshmallow stay centered and prevents it from sliding off as it melts.
- Toasting Level: Keep a close eye on the marshmallows during the final baking step. They can go from perfectly golden to burnt very quickly. You want them just lightly toasted and gooey.
- Cooling: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack. This allows the cookies to set and the marshmallow to firm up slightly, making them easier to handle.
- Storage: Store these cookies in an airtight container at room temperature for up to 3-4 days. For the best gooey experience, a quick 10-15 second reheat in the microwave can bring them back to life.
