Ingredients
- 1 cup unsalted butter
- ¾ cup granulated sugar
- 1 cup light brown sugar
- 2 large eggs
- 1 tablespoon vanilla extract
- 2 ¾ cup cake flour*
- 1 teaspoon baking soda
- 1 teaspoon fine sea salt
- 1 ½ cup M&M's (milk chocolate)
- 1 cup semisweet chocolate chips
Instructions
- Preheat the oven to 350° F. Line a 9x13 inch pan with parchment paper and set aside.
- Whisk together the flour, baking soda, and salt in a bowl and set aside.
- Add the butter, granulated sugar, and brown sugar to a standing mixer. Mix on medium speed for about 3 minutes, until creamy and slightly lighter in color. Scrape down the sides halfway through.
- Add the vanilla and eggs and mix on medium speed until well combined. Scrape down the sides of the bowl halfway through.
- Add the whisked dry ingredients to the standing mixer and mix on the lowest setting until just combined. Add the chocolate chips and Mu0026Ms and mix in by hand with a rubber spatula–this minimizes the risk of overworking the cookie dough.
- Add the dough to the 9x13 pan and smooth over the top with a spatula. If you'd like, add extra M&Ms and chocolate chips to the top.
- Bake for about 25-30 minutes, until golden. Let cool on the counter until room temperature (or else the bars will completely fall apart when you cut into them). Enjoy!
Notes
*Cake flour keeps these cookie bars soft. If you don't have cake flour, you can use all purpose flour and cornstarch. Rather than 2 ¾ cup cake flour, use 2 ½ cup all purpose flour + ¼ cup cornstarch. Just whisk the cornstarch in with the other dry ingredients.
