Is there anything better than a soft cookie in bar form? Where the edges are just lightly golden brown and a tad bit crunchy… and the inside is gooey and soft and melts in your mouth? Let me answer that for you…. no.

These bars are my favorite sugar cookie recipe baked up in bar form. A few tips and tricks. 1: use a 9×9 pan. Don’t try and do it in a 9×13 or an 8×8… it won’t be the same. Trust me – there’s a reason I developed it this way!

2: don’t skimp on the M&M’s and the sprinkle of salt on top. It really makes all the flavors sing!

3: proceed with caution once these are baked and cut. I’ve eaten pretty much an entire pan once before and I’m not even remotely exaggerating. Thomas had to remove the last 2 squares from the house because I could NOT BE STOPPED.

Soft Sugar M&M Cookie Bars

Soft Sugar M&M Cookie Bars

Ingredients

  • 1 cup butter, melted
  • 2 cup light brown sugar
  • 4 teaspoons vanilla extract
  • 2 large eggs
  • 2 cups all purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon of baking soda
  • 1 cup Milk Chocolate M&M’s, plus extra for garnish
  • Maldon sea salt (optional)

Instructions

  1. Preheat oven to 350 degrees.
  2. In a large bowl, combine the melted butter and brown sugar and mix with a wooden spoon for 1 minute until combined. Add the vanilla and eggs, making sure to scrape down the sides of the bowl, and mix until fully incorporated.
  3. Add the dry ingredients into the bowl and slowly mix until just combined. The batter will be a bit stiff, but that's normal. Fold in 1 cup of the Milk Chocolate M&M’s.
  4. Spray a 9x9 baking pan with baking spray and line it with parchment paper. Spoon the batter into the prepared baking sheet and sprinkle with the remaining Milk Chocolate M&M’s and Maldon sea salt if desired and transfer it into the oven. Bake for 30-35 minutes. Once the bars have baked, remove them from the oven and let cool for at least 2 hours before cutting and serving.

  1. I have been cooking the M&M bars for 45 min and they still aren cooked. Very soupy. What did I do wrong? Followed the re I’ve exactly but it wasn’t stiff when I mixed it. It was very liquidy.

    1. hmmmmm it should def be thick when mixed! Are you sure you added the correct amount of flour? That would be why it wouldn’t thicken up

  2. I have mini M&M’s can i substitute with them ? it calls for 1 cup and then sprinkle the top with them before baking. is that another cup or 1/2 cup ?
