Instructions
- Preheat the oven to 350°F. Beat together the butter and sugars. Add the eggs, vanilla, syrup, and baking soda. Stir in the peanut butter. Add the oats and stir again until well combined. Mix in the chocolate chips.
- Press the dough into the bottom of a large baking sheet, or jelly roll pan. Top with the m&ms and lightly press them into the dough. Bake for 16-17 minutes, until the bars are lightly browned and just past looking wet on top. They will not be firm, but they will set up as they cool.
