Calories 219kcal


  • 3 eggs room temperature
  • 1 1/4 cups light brown sugar
  • 1 cup granulated sugar
  • 1 stick unsalted butter softened
  • 12 ounces creamy peanut butter
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1 cup M&M's® Holiday Baking Minis divided
  • 1/2 cup mini semisweet chocolate chips
  • 4 1/2 cups Original Instant Quaker Oats
  • 2 teaspoons baking soda


  • Preheat oven to 350°F. Line two large cookie sheets with parchment paper or baking mats.
  • In a large mixing bowl, stir together the eggs and sugar until smooth. Add the butter, peanut butter, vanilla and salt. Mix well. Stir in 1/2 cup of the M&M's® Holiday Baking Minis, chocolate chips, oats and baking soda.
  • Scoop out heaping tablespoons of dough and form into balls. Place on prepared cookie sheets then gently press balls with the palm of your hand. With the remaining 1/2 cup of M&M's® Holiday Baking Minis, place 5-7 candies on top of each cookie. (They look really pretty this way.) Bake for 12-16 minutes or until light golden brown on the edges. They will be soft, but will firm up when they cool. Do not over bake or they will be too hard. Let cool in pans for 10 minutes before transferring to a wire rack to cool completely. (I made 12 cookies per cookie sheet and the recipe makes 3 dozen, so you can remove cooled, baked cookies and reuse the parchment lined cookie sheet for the last batch.)
  • Store covered at room temperature for up to 3 days or freeze for up to 2 weeks.


Note: These cookies make a great gift for the holidays. Put them in a festive container such as the Glad® Holiday Edition containers and tie with a pretty ribbon.
