Ingredient Notes

• Butter: Use real, salted butter for the best flavor. Do not use margarine or whipped butter.

• Peanut Butter: Creamy, standard peanut butter works best for a smooth dough. Natural peanut butter with separated oil can change the dough texture.

• Oats: Use old-fashioned rolled oats. Do not use instant or quick-cooking oats, as they will change the cookie’s texture.

• Mix-ins: This recipe uses a combination of semi-sweet chocolate chips and M&M’s. You can substitute milk chocolate chips or peanut butter chips. You can use any color of plain M&M’s.

• 1 cup light brown sugar, packed

• 2 teaspoons vanilla extract
• 2 teaspoons baking soda
• 4 ½ cups old-fashioned rolled oats

Step-by-step Instructions
