Ingredients
  

For the Cookie Dough

  • 1 cup unsalted butter, softened Make sure it is properly softened.
  • 1 cup granulated sugar
  • 1 cup packed brown sugar
  • 1 cup creamy peanut butter Use regular, not natural-style peanut butter.
  • 2 large eggs
  • 1 tablespoon vanilla extract

For the Dry Ingredients

  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 cups old-fashioned oats Do not use quick oats.

For the Mix-ins

  • 1 cup chocolate chips
  • 1 cup candy-coated chocolate candies (like M&Ms)

Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
  • In a large bowl, beat the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy.
  • Add the peanut butter and mix until fully blended. Then add the eggs one at a time, mixing each in before adding the next. Stir in the vanilla until smooth.
  • In a separate bowl, whisk together the flour, baking soda, and salt.
  • Combine the dry ingredients with the wet mixture until just combined.
  • Fold in the oats, chocolate chips, and candy-coated chocolates until the dough is well mixed.
  • Drop rounded spoonfuls of dough onto the prepared baking sheets.

Baking

  • Bake for 10–12 minutes until the edges are set and lightly golden, and the centers look slightly soft.
  • Let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

For best results, do not overbake. The cookies will finish cooking as they cool. Use properly softened butter to ensure a creamy dough. For a bakery-style look, save some candy to press onto the top before baking.
