Preheat the oven to 350°F. Prepare the brownies according to the package directions. Start by pouring the brownie mix into a large bowl. Next, add the water, vegetable oil, and eggs. Then, stir the mixture for about 50 strokes until everything is incorporated. Stir in Plain Halloween M&M's.
Spray two 12-well regular sized muffin pans with non-stick spray. And using an ice cream scoop, divide the batter evenly between the two pans1, filling each well about half way full.
Next, place one Halloween Orange Creme Filled Oreo in each well.
Put on a pair of vinyl gloves and place one piece of Nestlé Toll House M&M's Ghoul Mix Sugar Cookie Dough in the palm of one hand. Then, using your other hand, press the dough into a flat circle.
Place one piece of Pillsbury Halloween Shape Sugar Cookie Dough on top of the already smooshed piece of dough and press the two pieces of dough together.
Lay the prepared cookie dough on top of one of the Oreos and press the dough down into the pan so that none of the brownie mixture is visible.
Repeat steps 4-6 with the cookie dough until all of the wells have the cookie dough on top.
Bake the pans one at a time in a 350°F for 20-22 minutes.
Remove the pans from the oven and allow them to cool on a wire rack. After being out of the oven for about five minutes, run a knife around the edges to loosen the brookie cups. Let them cool in the pan for about ten more minutes, then remove them from the pan and allow them to cool on the wire rack. Once cooled, store them in an airtight container.
