Servings: 18 bars
- 1 stick butter unsalted, softened
- 1 cup light brown sugar
- 1/2 cup creamy peanut butter
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1 3/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 3/4 cups quick-cooking oats
- 3/4 cup semi-sweet chocolate chips
- 1 cup mini M&M's
Preheat oven to 350 degrees. Line 9x13 pan with parchment paper. Set aside.
Beat butter and sugar together in a large bowl of a stand mixer until creamy. Add peanut butter and vanilla and combine. Add eggs one at a time until combined.
In a separate medium bowl, add flour, soda, salt, and oats. Whisk until combined. Add dry ingredients to mixer and mix on low just until combined. Add chocolate chips and 1/4 cup of M&M's. Mix just until evenly distributed in dough.
Scoop dough into prepared baking pan. Using your hands, press dough firmly in pan to spread it evenly. Sprinkle remaining 1/4 cup of M&M's over dough and press them into dough.
Bake for 14-16 minutes, or until edges are browned and center is cooked. Remove from oven and let them cool for at least 10 minutes before cutting.
