Chewy M&M Cookie Bars
What do you make when it’s freezing, windy and rainy outside and you have two sick little boys on your hands? You make m&m cookie bars that’s what! I mean seriously, wouldn’t these just cheer you right up?
I use to LOVE it when my mom or grandmother made cookie bars growing up. Cookies are cool and all but there is just something about the cookie BAR. Thick, chewy, and chocked full of chocolate chips or whatever you choose to add in them.
I will go on record and say these are the BEST m&m cookie bars EVERRR!!! I’ve had plenty of cookie bars in my day and these lovelies bake up thick, chewy and soft in all the right places. They are full of m&m’s which makes me so happy!
I don’t know too many kids that wouldn’t love to come home from school to a plate of these babies and a tall glass of milk waiting on them.
Isaac said these m&m cookie bars were the “best things he’s ever tasted in his whole life” lol So I’m thinking I’ll be making these more often now. It’s really just a good blondie recipe with m&m’s added in. It has a delicious buttery taste that is pretty darn addictive. I’m not even going to tell you how many I had.
Watch me make these chewy m&m cookie bars from start to finish!
