Ingredients
Scale
Dry Ingredients
- 2 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
Wet Ingredients
- 1 cup unsalted butter (melted)
- 1 cup brown sugar
- ½ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
Add-ins
- 1 ½ cups M&Ms, plus extra for topping
Instructions
- Prepare Your Pan and Preheat Oven: Preheat your oven to 350°F (175°C) and lightly grease or line a 9×13-inch baking pan with parchment paper to ensure easy removal of the bars.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, and salt to evenly distribute and create the right structure for the bars.
- Cream Butter and Sugars: In a large mixing bowl, melt the unsalted butter and then stir in the brown sugar and granulated sugar until the mixture is smooth and well combined.
- Add Egg and Vanilla: Beat in the egg and vanilla extract into the butter and sugar mixture until fully incorporated, helping to bind the ingredients and keep the bars moist.
- Combine Wet and Dry Ingredients: Gradually add the dry flour mixture into the wet ingredients, stirring just until combined to avoid overmixing and maintain a chewy texture.
- Fold in M&Ms: Gently fold in the M&Ms, reserving a handful to sprinkle on top of the batter for extra color and crunch.
- Bake to Perfection: Spread the batter evenly in the prepared pan and press down slightly to compact it. Sprinkle the reserved M&Ms on top, then bake for 20 to 25 minutes until edges are golden and a toothpick inserted comes out with moist crumbs.
- Cool and Slice: Let the bars cool completely in the pan on a wire rack before slicing into squares, which helps them set and hold together well.
Notes
- Use room temperature eggs for better mixing and lighter texture.
- Do not overmix the dough to keep the bars soft and chewy.
- Press batter evenly in the pan to bake uniformly.
- Adding extra M&Ms on top makes the bars look attractive and adds crunch.
- Cool completely before slicing to prevent crumbling.
