  • 1/2 Cup Unsalted Butter (softened)
  • 3/4 Cup Brown Sugar (packed)
  • 3/4 Cup Peanut Butter (creamy)
  • 1 Large Egg
  • 2 Teaspoons Vanilla Extract
  • 1 Teaspoon Corn Starch
  • 1/2 Teaspoon Baking Soda
  • 1/4 Teaspoon Salt
  • 1 1/4 Cup All-Purpose Flour
  • 1/2 Cup Quick Oats
  • 1/2 Cup Semi-Sweet Chocolate Chips
  • 1/2 Cup Coated Chocolate Candies (like M&M's)


  • Using a large bowl with a hand mixer or a stand mixer with the paddle attachment, cream together the butter and brown sugar until fluffy (about 3 minutes).
  • Next, add the peanut butter, egg, and vanilla. Continue to mix until smooth, scraping down the sides as needed.
  • Add the cornstarch, baking soda, salt, and flour next. Mix on low speed just until combined, but don’t over mix. Pour in the quick oats, chocolate chips, and chocolate candies, and continue to mix until combined.
  • Transfer the dough to the refrigerator to chill for at least 30 minutes.
  • Preheat the oven to 350 degrees, and line a baking sheet with parchment paper or a silicone mat.
  • Roll about 2 tablespoons of dough into a ball and gently press down in the center (don’t make them completely flat). Add additional chocolate candies or chocolate chips to the top if you’d like.
  • Bake for 11-13 minutes. The centers will still look slightly soft and under cooked. Remove the cookies from the oven and allow them to cool on the baking sheet before transferring them to a cooling rack. All to cool for about 10 minutes before eating.
  • Store the cookies in an airtight container at room temperature for up to 5 days.
