Equipment Needed

To make these M&M cookie bars, here’s what you’ll need-

  • Two large mixing bowls
  • Hand mixer or stand mixer
  • Whisk
  • A 9×13 inch pan
  • Parchment paper or foil
  • A cake spatula

How to make Chewy Valentine’s Day Cookie Bars

Prep- Preheat your oven to 325, and line your 9×13 baking dish with the parchment paper or foil. Set aside. If you use foil, give it a spritz with some non-stick cooking spray.

Mix- In a large mixing bowl, beat the softened butter until smooth. Add the brown sugar and granulated sugar, and cream those together with the butter, for about 1-2 minutes. Add the eggs and vanilla, and mix until just combined.

Dry Ingredients- In a separate bowl, whisk together the dry ingredients- flour, baking soda, and salt.

Combine- Add the dry ingredients to the wet ingredients, mixing until just combined. You’ll still have some flour spots left.

Add the chocolate- Add the chocolate chips and M&M candies, folding everything together until your dough forms and the candy is distributed throughout.

Press into the pan- Press the dough evenly into your prepared baking sheet. It may be easiest to use your hands for this part.

Add some extra candies- Before baking, press some extra chocolate chips and M&Ms into the top of the dough.

Bake- Bake for 35-40 minutes, until the bars are beginning to turn golden brown on top.

Cool- After baking, allow the bars to cool completely before cutting, then remove them from the pan and cut into squares.

Valentine’s M&M Cookie Bars Tips & Tricks

  • Make the bars thinner by using a larger baking pan, such as a jelly roll pan. Reduce your bake time slightly for thinner bars.
  • Customize your cookie bars by adding any mix-in’s that you love- white chocolate chips, nuts, and other candies are all great options.
  • Swap the base dough in this recipe for a sugar cookie or peanut butter cookies variety to really change these up.
  • Store any leftovers in an airtight container, for up to one week.
