Instructions
Preheat oven to 350 degrees (F). Line an 9x13-inch baking pan with parchment paper. Set aside.
In a saucepan over medium heat, melt butter. Continue cooking, swirling the pan occasionally, until browned.
Remove from heat and cool for a few minutes, then scrape the butter into a large heat proof mixing bowl.
Whisk in both sugars and mix until well combined. Stir in the vanilla. Then add in the eggs and egg yolks, beating until combined.
Using a rubber spatula, fold in the flour and salt, mixing until just combined. Finally, fold in the M&Ms and chocolate chips. Scrape the batter into the prepared pan.
Bake for 26 to 30 minutes, or until the edges are firm and golden and the center is just slightly wobbly.
Cool in pan for at least 1 hour before cutting. Sprinkle with flaky sea salt before serving, if desired.
