Ingredients

Scale

Wet Ingredients:

  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup light brown sugar, packed
  • ½ cup granulated sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract

Dry Ingredients:

  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 3 cups old-fashioned rolled oats

Mix-ins:

 

  • 1 cup raisins (soaked in warm water for 10 minutes and drained)
  • ½ cup chopped walnuts (optional)

Instructions

  1. Preheat the oven: Set your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

  2. Cream the butter and sugars: In a large mixing bowl, use an electric mixer or a whisk to beat together the softened butter, brown sugar, and granulated sugar until smooth and fluffy (about 2 minutes).

  3. Add eggs and vanilla: Mix in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.

  4. Combine dry ingredients: In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.

  5. Mix wet and dry ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing to keep the bars tender.

  6. Fold in oats, raisins, and nuts: Gently stir in the oats, drained raisins, and walnuts (if using), making sure they are evenly distributed.

  7. Spread the dough in the pan: Press the dough evenly into the prepared baking pan, smoothing the top with a spatula.

  8. Bake: Place the pan in the preheated oven and bake for 22-25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.

  9. Cool and slice: Allow the bars to cool in the pan for at least 20 minutes before slicing into squares or rectangles. This helps them set and prevents crumbling.

  10. Serve and enjoy: Enjoy warm or at room temperature with a cup of coffee, tea, or a cold glass of milk!

Notes

  • For extra chewiness, remove the bars from the oven when the center still looks slightly underbaked—they will continue to set as they cool.
  • Customize your mix-ins: Swap raisins for dried cranberries, chocolate chips, or shredded coconut for a unique twist.
  • Make it gluten-free: Substitute all-purpose flour with oat flour or a 1:1 gluten-free flour blend and ensure your oats are certified gluten-free.
  • Storage: Keep in an airtight container at room temperature for up to 5 days, in the refrigerator for up to 10 days, or freeze for up to 3 months.
