Gooey marshmallow-filled, chocolate-layered, graham-cracker crumb coated oatmeal cookie bars. How good does that sound?

Bottom and Middle Layer

Preheat the oven to 350 degrees F. Line an 8 x 8 baking pan with parchment paper and set aside.

In a small bowl, combine all of the ingredients for the base layer. Stir until a crumbly type of dough has been formed. Press this "dough" into the bottom of an 8 x 8 baking pan.

Cook for 10 minutes or until lightly browned on top and remove from the oven.

Sprinkle the chocolate chips on top to melt.

Sprinkle the marshmallows on top of the chocolate chips.

Top Layer

Beat together the brown sugar and butter until light and creamy. Stir in the oats, coarsely crushed graham crackers, and flour.

Scoop the dough (with a cookie scoop) over the marshmallow layer. The dough doesn't cover it completely, but will cook together somewhat. Just evenly disperse scoops of dough on top of the marshmallows and briefly spread out the scoops.

Return to the oven for about 5 minutes (it will still be a bit gooey), then remove and allow to cool. These taste great right out of the oven, but take a good hour to fully set. If you don't mind messy bars, then dig in!

If desired, top the mostly cooled bars with a handful of miniature chocolate chips
