These S'mores Bars are chewy, ooey and gooey! Layered with a graham cracker cookie base, marshmallow creme and milk chocolate bars. These fabulous dessert bars are a great way to eat s'mores without the campfire!
Preheat the oven to 350°F and line an 8x8 baking dish with parchment paper or grease it very well.
In a stand mixer with paddle attachment or large mixing bowl with hand mixer, cream together the softened butter, brown sugar and white sugar until light and fluffy.
Add the egg and vanilla extract and beat together until well combined.
Add the baking powder, salt, whole wheat flour and graham cracker crumbs. Mix on low just until combined.
Add the tablespoon of cold water and mix just until the dough fully comes together.
Press ⅔ of the cookie dough evenly into the bottom of the prepared baking dish.
Add the chocolate bars on top of cookie dough.
Spread the marshmallow creme over the chocolate bars.
Finish with the remaining dough slightly flattened into large chunks. It will not cover all the marshmallow creme but that is exactly what you want. A little bit peeking out.
Bake the bars for 30-35 minutes until the cookie dough no longer looks glossy.
Let bars cool completely in pan. Then remove from dish, slice and enjoy!
