Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 3 cups rolled oats (not instant)
  • 1 cup chocolate chips (semi-sweet or milk chocolate, your preference!)
  • 1 cup chopped walnuts or pecans (optional, but highly recommended)
  • 1/2 cup raisins (optional)

Instructions

  1. Cream Butter and Sugars: In a large bowl, cream together softened butter, granulated sugar, and brown sugar until light and fluffy (3-5 minutes).
  2. Add Eggs and Vanilla: Beat in eggs one at a time, then stir in vanilla extract.
  3. Combine Dry Ingredients: In a separate bowl, whisk together flour, baking soda, cinnamon, and salt.
  4. Combine Wet and Dry: Gradually add dry ingredients to wet ingredients, mixing on low speed until just combined. Do not overmix.
  5. Add Oats, Chocolate Chips, Nuts, and Raisins: Stir in oats, chocolate chips, walnuts (or pecans), and raisins (if using).
  6. Preheat Oven and Prepare Pan: Preheat oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or line with parchment paper.
  7. Press Dough into Pan: Press dough evenly into the prepared pan.
  8. Bake: Bake for 25-30 minutes, or until edges are golden brown and a toothpick inserted into the center comes out with just a few moist crumbs.
  9. Cool Completely: Let cool completely in the pan before cutting into squares.
  10. Cut and Serve: Cut into squares and enjoy!

Notes

  • Use room temperature butter and eggs for best results.
  • Don’t overmix the dough.
  • Customize with different chocolate chips, nuts, or dried fruit.
  • For gluten-free, use a gluten-free all-purpose flour blend.
  • Store in an airtight container at room temperature for up to 3 days or freeze for longer storage.
  • Experiment with different spices like nutmeg or cloves.
  • Try almond or maple extract instead of vanilla.
  • Reduce sugar and add flaxseed meal or applesauce for a healthier version.
  • Add a cream cheese frosting or glaze for an extra treat.
