Whisk together the all-purpose flour, salt, and baking soda in a medium bowl.
1 ¼ Cup All-Purpose Flour, ½ teaspoon Kosher Salt, ¼ teaspoon Baking Soda
Mix together the butter, sugars, egg, and vanilla in a large bowl. Add the dry ingredients and stir until everything is combined. Finally, stir in the chocolate chips and m&ms.
⅓ Cup Unsalted Butter, ¼ Cup Brown Sugar, ¼ Cup Granulated Sugar, 1 Egg
Divide the dough into four even balls (about 145g each) and roll into spheres - place on a lined plate or baking tray. Place your dough in the fridge overnight, or at a bare minimum for thirty minutes - this helps add to the texture, flavor and spreading of the cookie when they are ready to bake.
1 Tablespoon Vanilla Extract, ½ Cup Chocolate Chips, ½ Cup Mini M&Ms
Prepare your baking sheets with parchment paper. Place the cookies about 3-4 inches apart on your baking sheets.
Preheat oven to 350 degrees and one sheet at a time, bake your cookies until the edges are firm and the centers are soft, about 13-15 minutes. These are big cookies so they will take some time to bake through!.
Sprinkle with flakey sea salt, cool your cookies on a wire rack and enjoy!
