Domestically Inept: S'more Cookie Brownies? Yes Please!

Okay, so this isn't exactly a story of baking success. After all, us domestically inept people are bound to have a few failures now and then...or perhaps quite often.....Anyways, I've been dreaming of S'mores lately. Unfortunately, its too cold to sit outside and build a fire on the patio and microwave S'mores just aren't as good.
So one evening I was browsing around on marthastewart.com (my favorite website) and found a recipe for Outrageous Chocolate Cookies. I then began brainstorming and wondering if I could somehow incorporate the elements of a S'more into these cookies. So below is my attempt at doing that. I will say that although the cookies turned out quite delicious, they did not hold their shape all that well. (I'll explain why later). So then I decided to slather the batter into a baking dish and make brownies out of them. These, I must say are quite good. So even though they were meant to be cookies, they turned out to be better as brownies. Thus, I give you...the cookie-brownie.

Lori's S'more Cookie Brownies

Ingredients:

10 graham cracker halves
1 stick of unsalted butter, cut into tablespoon-size pieces
2/3 cup AP flour
1 tsp baking powder
1 tsp kosher salt
4 eggs
1 & 1/2 cups packed light brown sugar
2 tsp pure vanilla extract
16 ounces dark chocolate chunks
16 ounces of bittersweet chocolate chips
1 cup of miniature marshmallows

Directions:

Step 1: Preheat oven to 350F. Break up the graham crackers and pulse in a food processor until ground into fine granules. Measure out 2/3 cup; this will act as a substitute for what otherwise would have been flour in our recipe. I think I'll call it, "graham flour." Set the remaining graham flour aside.

Step 2: Combine the bittersweet chocolate and the butter in a heat-proof bowl and melt in a double-boiler over low heat.

Step 3: Stir frequently and melt till smooth and shiny.

Step 4: Meanwhile, beat the eggs and brown sugar using a mixer on medium speed. Do this until it becomes pale colored and frothy (2-3 minutes). Add in the vanilla.

Step 5: Sift together the dry ingredients: flour, graham flour, baking powder, and salt

Step 6: Place the mixer speed on low, add in the melted chocolate and mix until well combined.

Step 7: Slowly add the dry ingredients, mixing completely. Then add in the chocolate chunks and marshmallows.

Step 8: For cookies, use a medium sized cookie scoop and scoop the dough onto parchment-lined baking sheets. Sprinkle a little graham flour on the top.

Here is where things start going awry. After baking for about 14 minutes, some of the cookies came out great. Others, however, split apart. I think it's because the marshmallows melted and carmelized and created air pockets. Perhaps less marshmallows would be better?

So after a few crumbly cookies, I decided to see if brownies would be better. I greased an 8 x 8 baking sheet, slathered in the remaining batter and sprinkled some graham flour on top. I then baked for about 25 minutes. The brownies seemed to come out much better. They are very chewy and they do taste like s'mores.
