Ingredients

2 cups creamy peanut butter
2/3 cup butter, softened
1-1/3 cups sugar
1-1/3 cups packed brown sugar
4 large eggs, room temperature
2-1/2 teaspoons baking soda
1 teaspoon vanilla extract
1 teaspoon light corn syrup
6 cups old-fashioned oats
1 cup semisweet chocolate chips
1 cup milk chocolate M&M's

Directions

In a large bowl, cream peanut butter, butter, sugar and brown sugar until light and fluffy, 5-7 minutes. Beat in eggs, baking soda, vanilla and corn syrup. Add oats and mix well. Stir in chocolate chips and M&M's. Cover and refrigerate 1 hour.
Preheat oven to 350°. Drop by 1/4 cupfuls 3 in. apart onto ungreased baking sheets. Bake 14-18 minutes or until edges are lightly browned. Cool 5 minutes before removing from pans to wire racks to cool completely. Store in an airtight container.

Test Kitchen Tips

Corn syrup is an invert sugar, meaning it is liquid in its natural state. This quality helps it stop sugar crystals from forming in frostings, candies and other sweet recipes.

Dark brown sugar contains more molasses than light or golden brown sugar. The types are generally interchangeable in recipes. But if you prefer a bolder flavor, choose dark brown sugar.
