The only thing I may possibly like better than soft and chewy M&M’S® cookies are cookie bars.

Bars are my favorite kitchen shortcut because they’re so fast and easy to make.

For these very soft, slightly chewy, buttery bars that are loaded with M&M’S and chocolate chips, I called upon my trusty blondie base.

I stirred in 1 cup of the new Crispy M&M’S, but anything from Dark to Pretzel to Peanut Butter M&M’S would be wonderful. M&M’S just launched a new Pinterest page where you can check out new recipes for baking inspiration.

I loved the texture contrast of the soft bars, with gooey chocolate chips, and the Crispy M&M’S that stay crispy even after being baked. My family’s eyes lit up when they saw these and they sure didn’t last long.

Bars are my favorite kitchen shortcut because they’re so fast and easy to make. No dough to chill or individual cookies to form. For these very soft, slightly chewy, buttery bars that are loaded with M&M’S and chocolate chips, I called upon my trusty blondie base. When I want an easy, fuss-free, one-bowl, no-mixer recipe that I know everyone will love, it’s my go-to . With 25+ versions and counting, it never lets me down. It’s an easy recipe to memorize because everything is ‘one’. In the 1 bowl used, melt 1 stick of butter, stir in 1 egg, 1 cup of brown sugar, 1 tablespoon vanilla, and 1 cup flour. I stirred in 1 cup of the new Crispy M&M’S, but use your favorites. I loved the texture contrast of the soft bars, gooey chocolate chips, and the crispy M&M’S.

Ingredients

  • 1/2 cup unsalted butter (1 stick), melted
  • 1 large egg
  • 1 cup light brown sugar, packed
  • 1 tablespoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt, or to taste
  • 1 cup Crispy M&M’S (or your favorite M&M’S like Dark, Pretzel, Peanut Butter, plus more for sprinkling
  • 3/4 cup semi-sweet chocolate chips, plus more for sprinkling

Instructions

  1. Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
  2. In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
  3. Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
  4. Add the flour, salt, and stir until just combined, don’t overmix.
  5. Stir in the M&M’S and chocolate chips.
  6. Turn batter out into prepared pan, smoothing the top lightly with a spatula.
  7. If desired, evenly sprinkle about 1 tablespoon each of M&M’S and chocolate chips for an extra visual pop, tapping them down lightly with your fingertip.
  8. Bake for about 25 to 28 minutes (I baked 26 minutes), or until done. A toothpick inserted in the center should come out clean, or with a few moist crumbs, but no batter. Bars firm up as they cool. Allow bars to cool in pan for at least 1 hour before slicing and serving. Bars will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months.
