Preheat the oven to 350 degrees and grease a 9x13 pan.

In a small bowl, whisk together flour, graham cracker crumbs and baking powder.

In a large bowl, cream butter and sugar. Add egg, beating after each addition.

Add dry ingredients to the butter/sugar mixture, and mix well until all dry ingredients are absorbed. You should have a very moist dough.

Julie suggests dividing the dough in half. I'd suggest dividing it into thirds, and placing two thirds of the dough into the bottom of your 9x13 pan.

Next, carefully spread the container of Marshmallow Fluff on top of the dough. I found that if I microwaved the fluff for approx. 15 seconds it came out of the container much more easily. Second, evenly sprinkle Enjoy Life Foods chips on top of fluff.

Finally, sprinkle remaining dough on top of chocolate chips. It may not cover it perfectly. That's okay! We want that marshmallow fluff to be poking out!

Bake bars in a preheated 350 degree oven for 30-35 minutes. Remove from the oven when cookie dough is fully baked. Cool completely before trying to cut. Julie suggests that they may cut best when they've been refrigerated.
