Ingredients

Scale
  • 1 1/2 cups old-fashioned rolled oats
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon (optional)
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar (light or dark)
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1 cup fresh or frozen blueberries
  • Optional: 1/2 cup chopped walnuts or pecans
  • Optional: 1/3 cup white chocolate chips
  • Optional: Zest of 1 lemon

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
  2. In a medium bowl, whisk together the oats, flour, baking soda, cinnamon, and salt until well combined.
  3. In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy, about 2-3 minutes.
  4. Beat in the egg and vanilla extract until smooth and glossy.
  5. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Do not overmix.
  6. Gently fold in the blueberries (and any optional add-ins like nuts, white chocolate chips, or lemon zest).
  7. Use a cookie scoop or two spoons to drop dough balls (about 2 tablespoons each) onto the prepared baking sheet, spacing them about 2 inches apart.
  8. Bake for 11-13 minutes, until the edges are set and just starting to turn golden. The centers may look slightly underdone.
  9. Cool cookies on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

For gluten-free cookies, use a 1:1 gluten-free flour blend. For dairy-free, substitute vegan butter. Add lemon zest for a bright flavor, or nuts/white chocolate chips for extra texture. If using frozen blueberries, add them straight from the freezer to prevent color bleeding. Slightly underbake for extra chewy centers.
