Servings: 24
Ingredients
- ½ cup Peanut Butter 125g
- ½ cup Butter Softened
- ¼ cup Granulated Sugar 50g
- ¾ cup Brown Sugar 160g
- 1 teaspoon Vanilla
- 1 Large Egg
- ½ teaspoon Salt
- 1 teaspoon Baking Soda
- 1¼ cups All Purpose Flour 150g
- 1 cup Old Fashioned Oats 85g
- ¾ cup Semi-Sweet Chocolate Chips 170g
- ¾ cup M&M's Mini Regular or both
- ½ cup Peanut Butter Chips optional
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.
