Monster Cookie Brownie Bars

• 3/4 cups Unsalted Butter, Softened
• 3/4 cups Light Brown Sugar, Packed
• 1/4 cups Plus 2 Tablespoons, Granulated Sugar
• 1 cup Plus 2 Tablespoons Creamy Peanut Butter
• 2 Large Eggs
• 1-1/2 teaspoon Vanilla Extract
• 3/4 teaspoons Baking Soda
• 1-3/4 cup Plus 2 Tablespoons, All-purpose Flour
• 3/4 cups Quick Oats
• 1-1/2 cup M&Ms
• 3/4 cups Semi-Sweet Chocolate Chips
• 1 box (about 18 Oz. Size) Brownie Mix, Prepared According To Instructions, Or Your Favorite Recipe (See Note)

1. Preheat oven to 350u0b0F. Line a 9x13 baking dish with parchment paper, and spray with cooking spray. Set aside.
2. In the bowl of a stand mixer fitted with the paddle attachment, or using a hand-held mixer and large mixing bowl, cream butter and sugars together on medium speed until combined, about 2-3 minutes. Add peanut butter, eggs, and vanilla, mixing to combine and scraping down sides of bowl as needed.
3. With the mixer on low speed, mix in baking soda and flour, mixing until just combined. With a rubber spatula, fold in quick oats, M&Ms, and chocolate chips. Set aside.
4. Prepare brownie batter according to recipe directions.
5. Press half of cookie dough evenly in the bottom of the pan. Pour brownie batter on top and then crumble remaining cookie dough evenly over brownie batter.
6. Bake for 47-55 minutes, or until a toothpick comes out with moist crumbs when inserted. Cover the bars with foil if you notice the cookie top getting brown early (you might check around 30-40 minutes). Remove from oven and place on a cooling rack. Let cool almost completely before removing and serving.
7. Note: Make sure the brownie recipe you use yields a 9x13 pan of brownies.
