To make these monster cookie brownies, I started by pouring a package of Duncan Hines Chewy Fudge Brownie mix into a large mixing bowl along with two eggs, vegetable oil and water.
I stirred all of the ingredients together until no lumps remained.
Then I spooned the brownie batter into a well greased muffin tin, filling each cup about ⅓ of the way.
Then I set the muffin tin aside and added some peanut butter, softened butter, an egg, brown sugar, granulated sugar and vanilla to a large mixing bowl.
I used an electric mixer to cream the ingredients together until smooth.
Then I added some quick oats, flour and salt to the bowl.
I continued mixing with the electric mixer until fully combined.
Then I poured some mini M&Ms into the bowl.
I stirred the mini M&Ms into the peanut butter oatmeal cookie dough.
Then I placed a spoonful of cookie dough on top of the brownie batter in each muffin cup.
I baked the monster cookie brownies until the cookie was starting to brown on top and a toothpick inserted into the brownie came up with just a few crumbs.
Then I allowed the brownie cups to cool slightly before removing them from the muffin tin.
These Monster Cookie Brownie Cups are an easy and decadent dessert recipe.
