S’mores Stuffed Cookie Bars

S'mores Stuffed Cookie Bars

I just can’t get enough of s’mores. They are one of my hands down favorite summertime treats. The only way to make them better? Stuff s’mores into cookies to make these gooey, s’mores stuffed cookie bars. They are hands down my favorite summer cookie.

Goose definitely agrees. She was a down right marshmallow thief while I was taking these photos. Little stinker.

Better the marshmallows than the chocolate chips though. Have you ever seen what happens when a toddler eats chocolate chips on a hot summer day? It’s not pretty. The chocolate melts everywhere and gets in places that I didn’t think possible.  I’m guessing that she’s up on skin care trends I don’t know about. Chocolate facials. Maybe it’s a thing.

Back to the cookie bars. My husband actually surprised me by making this treat for me. It had been a tough week between a toddler that learned to undress and take her diaper off in her crib, a dryer that died, and dealing with a major car repair. The man is smart and throws cookies and chocolate my way. This is definitely one of the secrets to our happy marriage.

These s’mores stuffed cookie bars were the perfect cookie for that kind of crazy week. The recipe for the cookie dough base comes from my mother in law. The chocolate chip cookies she bakes are seriously addicting. Gooey, rich, and delicious, they might be the perfect chocolate chip cookie. Then take that cookie dough base, lay it down in a deep baking dish, and sandwich Hershey bars and marshmallows in the middle of it.

Oh yeah. The resulting deep dish s’mores stuffed cookie bars are out of this world. Soft baked and constantly melty, they are the cookie bar dreams are made of. Better yet for me, we updated the dough recipe to be gluten free by substituting the white flour with our favorite gluten free blend from Bob’s Red Mill. The recipe works well either made gluten free as we did or with the original version.
