Ingredients
Scale
Main Ingredients:
- 2.34 cups (343g) all-purpose flour
- 1 cup (226g) unsalted butter, melted and slightly cooled
- 1 cup (200g) packed brown sugar
- 1.14 cups (260g) M&Ms, mini or regular size
- 0.75 cup (135g) semi-sweet chocolate chips
- 2 large eggs, at room temperature
Wet Ingredients:
- 2 teaspoons pure vanilla extract
Dry Ingredients:
- 1.5 teaspoons cornstarch
- 1 teaspoon baking soda
- 0.5 teaspoon salt
- 0.5 cup (100g) granulated sugar
Instructions
- Prepare the oven environment by heating to 350°F and positioning a parchment paper liner inside a 9×13 inch baking vessel to ensure easy extraction of the cookie bars.
- Create a powdery foundation by thoroughly combining flour, cornstarch, baking soda, and salt in a medium mixing bowl, whisking until uniformly integrated.
- Transform melted butter into a silky base by vigorously blending brown and granulated sugars until the mixture achieves a smooth, glossy consistency.
- Enrich the butter-sugar mixture by incorporating eggs individually, ensuring each is fully integrated before adding the next, then introduce vanilla extract for aromatic depth.
- Gently fold the dry ingredient mixture into the wet ingredients, creating a cohesive dough that maintains a light texture.
- Generously distribute M&Ms and chocolate chips throughout the dough, ensuring even dispersal for consistent flavor and visual appeal in each bar.
- Transfer the dough into the prepared baking pan, carefully spreading the mixture to create an even layer that will bake uniformly.
- Position the pan in the preheated oven and bake for 25-30 minutes, watching for a golden-brown surface that indicates perfect doneness.
- Remove from the oven and allow the cookie bars to cool completely within the pan, which helps them set and makes cutting easier.
- Once thoroughly cooled, slice into rectangular bars, revealing the gooey, chocolate-studded interior.
Notes
- Customize M&Ms by choosing seasonal colors for festive look or matching party themes.
- Chill dough for 30 minutes before baking to prevent excessive spreading and create thicker bars.
- Replace some M&Ms with nuts like pecans or almonds for added texture and nutty flavor complexity.
- Use gluten-free flour blend to make recipe friendly for those with wheat sensitivities.
