What are M&M Cookie Bars made of?

They require only four easy ingredients:

  • 1 box vanilla cake mix
  • 2 large eggs
  • 1/2 cup butter
  • 2 cups M&M’s

How to make the perfect M&M Cookie Bars?

  1. In a large bowl, stir the first 3 ingredients together until well combined. Stir in M&M’s.
  2. Preheat the oven to 350 degrees F. Spray a 9×9-inch pan with nonstick spray.
  3. Then, spread and pat the cookie dough in the pan.
  4. Bake for about 20-25 minutes or until golden brown.
  5. Lastly, let them cool before cutting.

Can the dough be made in advance?

Yes, making the dough in advance is definitely an option. Once you made the dough, wrap it up in plastic, and store in the fridge for up to 2-3 days. When the time for cooking comes, let the dough rest at room temperature for a bit to soften.

How long will the M&M Cookie Bars stay fresh?

This delicious homemade dessert can be stored at room temperature for about 4-5 days.

Can you freeze the M&M Cookie Bars?

Yes. First, cool the bars completely and fully wrap it in plastic wrap, tightly. After that, wrap in aluminum foil. Freeze for up to 2-3 months. Defrost before serving.

M&M Cookie Bars Recipe Tips:

  • Let the cookies cool in the baking pan after you remove them from the oven. Because they are very soft, it’s best to let them rest a bit, so they will harden once they cool.
  • You can add chocolate chips to the mix, or Reese’s if you desire.
  • Use a chocolate cake mix for chocolate cookies.
  • You can also use a strawberry cake mix for strawberry cookie bars.

  • Spread and pat the cookie dough in the pan. Level the top with a spatula.
  • Bake for about 25-35 minutes or until golden brown. A toothpick inserted in the center should come out clean, or just a few crumbs, but not raw batter.
  • Let the cookie bars cool before cutting, as cooling will allow them to firm a bit.
