Instructions

Prepare the Pan and Oven: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it to prevent sticking.
Mix Wet Ingredients: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add eggs and vanilla extract, whisking until fully combined and creamy.
Add Dry Ingredients: In a separate bowl, whisk the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Do not overmix.
Fold in the Mix-ins: Gently fold in the M&Ms and chocolate chips using a rubber spatula, reserving a handful of M&Ms for garnishing the top if desired.
Spread and Top: Spoon the dough into the prepared pan and spread it out evenly. Sprinkle remaining M&Ms over the top and gently press them in for a colorful finish.
Bake: Bake for 23–28 minutes, or until the edges are golden brown and the center looks just set (a few moist crumbs on a toothpick is perfect). Don’t overbake for fudgy bars.
Cool and Cut: Allow the bars to cool completely in the pan on a wire rack. Once cooled, lift out using parchment paper and cut into squares or rectangles.

Notes

White whole wheat flour can be substituted for all-purpose for a wholesome touch.
Mix in chopped nuts or swap the chocolate chips for white or peanut butter chips for variation.
For neater bars, chill before cutting.
Store leftovers in an airtight container at room temperature for up to 4 days, or freeze for up to 3 months.
