Step-by-Step Instructions
- Prepare the Monster Cookie Dough by combining flour, cornstarch, baking soda, baking powder, and salt in one bowl. In another bowl, beat butter and sugars until fluffy, then mix in peanut butter, vanilla, and eggs. Gradually add dry mixture, oats, M&M's, and chocolate chips. Chill for 40 minutes.
- Make the Brownie Batter by preheating the oven to 325°F (163°C). Grease and line a 9x9-inch baking pan. Sift together flour, cocoa powder, cornstarch, and salt in a bowl. Beat together sugar and eggs until light and fluffy, then mix in melted butter, oil, and vanilla. Fold in dry ingredients and chocolate chips.
- Layer and Bake by spreading brownie batter in the pan and baking for 15 minutes. Flatten chilled cookie dough and layer over brownies. Bake for an additional 20-30 minutes until set and golden brown.
- Cool and Slice by allowing brownies to cool completely in the pan before slicing into 16 squares.

Notes
Ensure eggs are at room temperature for better incorporation. Chill cookie dough to prevent spreading and maintain chewiness during baking.
