1 cup (226 g) unsalted butter, melted and cooled 5 minutes
02 -
1 cup (200 g) packed light brown sugar
03 -
1/2 cup (100 g) granulated sugar
04 -
2 large eggs, room temperature
05 -
1 large egg yolk, room temperature
06 -
2 teaspoons vanilla extract
07 -
3 cups (360 g) all-purpose flour, spooned and leveled
08 -
2 teaspoons cornstarch
09 -
1 teaspoon baking soda
10 -
1 teaspoon fine salt
11 -
1 cup (170 g) semi-sweet chocolate chips, plus 2 tablespoons for topping
12 -
1 cup (200 g) M&M candies, plus 1/3 cup for topping
# Instructions:
01 -
Preheat the oven to 350 F. Line a 9x13-inch metal baking pan with parchment paper, leaving overhang on two sides, and lightly grease the exposed ends.
02 -
In a large bowl, whisk the melted butter, brown sugar, and granulated sugar until glossy. Whisk in the eggs, egg yolk, and vanilla until smooth.
03 -
Add the flour, cornstarch, baking soda, and salt. Stir with a sturdy spatula just until the dough comes together and no dry flour remains.
04 -
Fold in 1 cup chocolate chips and 1 cup M&M candies. Reserve the extra chips and candies for the top.
05 -
Spread the dough evenly in the prepared pan. Press the reserved M&M candies and chocolate chips across the top.
06 -
Bake for 24-28 minutes, until the edges are lightly golden and the center looks set but still soft. Cool completely in the pan, then lift out and slice into bars.
# Good to know:
01 -
Best texture comes from pulling the pan before the center looks fully firm.
02 -
Cool completely for clean slices.
03 -
Use seasonal M&M colors for holidays and parties.
