Oatmeal M&M Cookies
- 3 cups flour
- 1 1/2 cups brown sugar
- 1/2 cup granulated sugar
- 1 tsp baking powder
- 1 tsp baking soda
- 1 tsp salt
- 2 sticks cold butter, cubed
- 2 large eggs, room temperature
- 1 tsp vanilla
- 2 cups of oats
- 1 cup mini m&ms
Marshmallow Cream Filling
- 1/2 cup butter, softened
- 1 cup marshmallow fluff
- 2/3 cup powdered sugar
Instructions
- Preheat oven to 350°F. Line a cookie sheet with parchment paper. Also line a rimmed cookie sheet with parchment paper for chilling the dough.
- Make the oatmeal M&M cookies. In a medium mixing bowl, gently whisk flour, baking powder, baking soda, and salt.
- In the bowl of an electric mixer with a paddle attachment, beat cold butter cubes on medium speed until combined. Add in sugars and beat until whipped and creamy. Mix in eggs and vanilla until evenly combined. Scrape the edges of the bowl for any excess butter or sugar.
- Add flour to the creamed butter and mix on medium speed until a dough forms. Add oats and M&Ms, mix on low until just combined.
- Use a cookie scoop to scoop cookie dough balls onto the rimmed parchment-lined cookie sheets. You can fill this cookie sheet with as many dough balls as can fit. Chill in the freezer for 15 minutes. (If you don’t have a rimmed baking sheet, you can chill the dough on plates.)
- Remove chilled cookie dough balls and place them on the second parchment-lined baking sheet. Bake cookies for 12-15 minutes. Transfer the cookie sheet to a wire rack and let them cool completely before adding the marshmallow cream filling.
- Make the marshmallow cream filling. Cream the butter with the paddle attachment. Mix in marshmallow fluff and sprinkle in powdered sugar a little bit at a time. Mix until combined.
- Assemble the cream pies. Add a couple of spoonfuls of marshmallow filling on the flat side of a cookie. Gently press the bottom of another cookie on top of the filling to make a sandwich. Repeat to make the rest of the cookie sandwiches.
