Kids enjoy helping with cookie dough desserts. And it’s a fun kids in the kitchen project. Just don’t let them eat raw cookie dough.

I know. I used to sneak raw cookie dough as a kid too. It was so good.

However, Salmonella is always a possibility with any raw eggs. That’s no fun at all.

M&M cookie bars are an easy dessert recipe the whole family will enjoy. These rich and delicious cookie dough bars have a baked marshmallow topping with sprinkles and three kinds of M&Ms.

M&M Cookie Bar Recipe:

One 9×13 baking pan makes about 36 2×2 inch bars. That’s about right. These are delicious but rich and full of fun but naughty ingredients. You won’t need a huge piece.

These cookie dough bars are a twist on chocolate chip cookie dough bars.  White chocolate chips fit into the color scheme with the pastel candies. AND the white chocolate chips are actually a better flavor for blending with the M&M medley we have going here. 

Baking Tips:

  1. Make sure you warm your eggs to room temperature. They mix much better when warmed.
  2. Measure out the toppings. It’s tempting to throw on more candy or marshmallows than is called for.
  3. If a little is good, more is better right? Not true in this case. Stick to the recipe.
  4. Press in your cookie dough evenly. Keep it about the same height all over for the best baked results.
  5. Watch your marshmallows when you bake them. They will puff and then you take them out. Don’t let them caramelize. You want to keep the marshmallows a nice white color with some gooeyness to glue together the top and not ruin the look of the bars.
  6. Cool the bars completely before cutting them. They will cut much better when cooled and set.
