Monster Cookie Bars
These Monster Cookie Bars will only dirty one bowl, and super delicious! They're thick, chewy, satisfying, and wonderfully chocolatey.
Servings: 20
Ingredients
- ½ cup granulated sugar
- ⅔ cups light brown sugar, tightly packed
- 2 large eggs, room temp
- 2 tsp ground cinnamon
- ¼ tsp table salt
- 1 tsp pure vanilla extract
- 1 cup creamy peanut butter
- ⅓ cup salted butter, softened to room temp
- 1 ½ cup semi-sweet chocolate chips
- 1 tsp baking soda
- 3 cups quick-cooking oats
- ⅔ cup M&M's
Instructions
- Preheat oven to 350F with rack on lower middle position. Lightly grease a 9x13" glass baking pan; set aside.
- In the bowl of a stand mixer fitted with paddle attachment, mix together both sugars and eggs on medium speed, until well combined.
- Add cinnamon, salt, vanilla, peanut butter, and butter; mix until fully incorporated.
- Stir in the chocolate chips, baking soda, and oats to combine well. Scrape dough into prepared pan and lightly/evenly press to fill all corners. Lightly press M&M's evenly across top of dough.
- Bake 20 minutes or just until sides are golden brown. Do not over-bake. Bars will continue to set firmly upon cooling.
- Cool in pan, on wire rack completely. Cover and chill for ease of cutting. Cut chilled bars into squares and serve.
Notes
- Make sure your eggs are at room temperature. This will help them mix more easily into the dough and will also help your cookie bars to rise properly.
- When measuring your brown sugar, very tightly pack it into the measuring cup.
- Buy pre-stirred creamy peanut butter that has no oil separation. It blends more easily into the dough and gives your bars a smooth, consistent texture.
- Baked bars can be wrapped tightly and frozen for up to 2 weeks.
