Base Ingredients

  • 1 cup Unsalted butter Richness, moisture
  • 1 cup Peanut butter Creaminess, flavor
  • 3/4 cup Granulated sugar Sweetness
  • 3/4 cup Brown sugar Chewiness, moisture
  • 2 large Eggs Structure, binding
  • 1 teaspoon Vanilla extract Flavor enhancement

Dry Ingredients

  • 2 cups All-purpose flour Structure
  • 1 teaspoon Baking soda Lift, texture
  • 1/2 teaspoon Salt Flavor balance
  • 2 cups Old-fashioned oats Heartiness

Mix-ins

  • 1 cup Semi-sweet chocolate chips Chocolate flavor
  • 1 cup M&Ms Color, sweetness

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and prepare baking sheets with parchment paper.
  • In a large mixing bowl, beat together the unsalted butter and peanut butter on medium speed until creamy.
  • Gradually add in granulated sugar and brown sugar, mixing until fluffy, then add eggs one at a time and mix in the vanilla extract.

Mixing Dry Ingredients

  • In a separate bowl, whisk together the all-purpose flour, baking soda, and salt, then gradually add this flour mixture into the wet ingredients.
  • Fold in the old-fashioned oats, semi-sweet chocolate chips, and M&Ms until evenly distributed.

Baking

  • Drop rounded tablespoon-sized portions of the dough onto prepared baking sheets, spacing them about 2 inches apart.
  • Bake for 9–11 minutes or until edges are slightly golden and centers appear soft. Allow to cool on baking sheets before transferring to a wire rack.

Notes

For increased chewiness, consider replacing some all-purpose flour with oat flour. Chill dough for 30 minutes before baking to prevent spreading. Experiment with different mix-ins for unique flavors.
