Instructions
Preheat the oven to 350 degrees. Spray a 9x13 inch baking dish with nonstick spray and set aside.
In a large mixing bowl, cream Butter, Peanut Butter, and White Sugar for 2-3 minutes, allowing the mixture to become light and fluffy.
Add Egg and Vanilla Extract and continue to cream. Then mix in brown sugar and cream for 2-3 minutes. Scrape the sides of the bowl as needed to ensure you're using all the ingredients.
Gradually add the Baking Soda, Salt, Flour, and Oats. Mix until combined.
Using a wooden spoon, hand stir the Chocolate Chips, Peanut Butter Chips, and M&M candy-coated pieces into the cookie dough.
Press the monster cookie dough into a prepared pan or baking dish, smoothing the mixture out into an even layer with the back of a spoon or with a rubber spatula.
Bake at 350 degrees for 20-24 minutes, or until the edges are set and lightly golden.
Allow the cookie bar to cool in the pan.
Once completely cooled, slice the bar slab into 24 bars.
Store cooled cookies in a sealed container for up to a week. Best if enjoyed within 2-3 days.
Notes
TIP: I find these bars can be crumbly if additional ingredients are added. Do not add additional oats or flour to the cookie dough mixture.Storage
Store: Store cooled cookies in an airtight container for up to a week. Best if enjoyed within 2-3 days.
Freeze: Freeze cookies for up to 3 months. Place parchment paper between layers when stacking to prevent sticking.
