Dry Ingredients
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon salt
Wet Ingredients
- 1 cup unsalted butter (room temperature)
- 1 cup light brown sugar (packed)
- ½ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
Add-ins
- 1 ⅓ cup M&M candies (divided)
- 1 cup semi-sweet chocolate chips
- Preheat Oven and Prepare Pan: Preheat your oven to 350℉ (175℃) and line a 9×13 inch baking pan with parchment paper or foil. Set aside to ensure easy cleanup and to prevent sticking.
- Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking soda, and salt until well combined. Set this mixture aside.
- Cream Butter and Sugars: Using a stand mixer or hand mixer, beat the room temperature unsalted butter with the light brown sugar and granulated sugar until the mixture becomes light and fluffy, which usually takes about 2-3 minutes.
- Add Eggs and Vanilla: Add the eggs one at a time along with the vanilla extract, mixing on medium speed until fully incorporated.
- Combine Wet and Dry Ingredients: Reduce the mixer speed to low and gradually add the dry ingredients to the wet ingredients. Mix just until everything is combined and no flour streaks remain to avoid overmixing the dough.
- Fold in M&Ms and Chocolate Chips: Gently fold in 1 cup of the M&M candies and all of the semi-sweet chocolate chips using a spatula to evenly distribute without crushing the candies.
- Press Dough into Pan: Transfer the dough into the prepared baking pan and press it evenly with a spatula or your hands to form an even layer. Sprinkle the remaining ⅓ cup of M&M candies on top and gently press them into the dough.
- Bake: Place the pan in the preheated oven and bake for 22 to 30 minutes. The bars are done when the top is golden, edges are lightly browned, and the center is just set but still slightly soft.
- Cool and Slice: Remove the pan from the oven and place it on a cooling rack. Allow the cookie bars to cool completely in the pan to set before slicing into squares and serving.
Notes
- For softer bars, bake closer to 22 minutes; for crisper edges, bake closer to 30 minutes.
- You can substitute the semi-sweet chocolate chips with milk chocolate chips or chunks if preferred.
- Make sure the butter is at room temperature before mixing to ensure a smooth and fluffy dough.
- Use parchment paper for easy removal and clean-up.
- Store leftover bars in an airtight container at room temperature for up to 4 days.
