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

Instructions

- 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.

- 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.
