Thick and chewy M&M Cookie Bars are perfect for your cookie exchange, dessert potluck or an after school snack using just a few ingredients!
I needed a dessert that was easy to make, transport and could withstand being outdoors in the heat. M&M Cookie Bars ticked all the boxes. I set down the platter and came back 30 minutes later to find it empty. Gone. They were that popular and the burgers weren’t even being served yet!
I ended up having to go home and whip up another batch of M&M Cookie Bars just so I could try them myself and I learned they are, indeed, that delicious!
These aren’t your regular cookie bars…. oh no… they don’t even use cookie dough! Cake and pudding mix is the secret to these bad boys. The smell of the batter alone is pure, sugary heaven and the end result is reminiscent of a half baked cookie cake.
In fact, next time I might frost them! Make cookie bars in under 30 minutes with fewer than 5 ingredients. Great for a special treat at school or a soccer game, for a potluck at work or a BBQ at the neighbor’s. People will rave. I promise.
Make sure to pay attention to the size of the pudding mix you purchase. There are technically 4 different weights and the smallest two and largest two have identical boxes except for the weight. You’ll need the 5.1 ounce box!
One thing I did learn- make these directly in the pan, preferably glass. The first time around I used parchment and ended up with a globby mess instead of moist bars. They will get stuck in aluminum foil as well.
Tools for making Thick and Chewy M&M Cookie Bars:
9 x 13 Glass Baking Dish– an absolute essential for any kitchen! Use it for baking, marinating or storing. Get one with a lid, you’ll thank me later.
Stand Mixer- While this is an investment, I can guarantee you will use it more than you realize and will never regret the decision.
