Description

These Blueberry Oatmeal Cookies are a delightful treat combining the chewy texture of oats with the sweet burst of fresh blueberries. Made with simple pantry staples and baked to golden perfection, these cookies offer a balance of wholesome ingredients and classic flavors, perfect for a healthy snack or dessert.


Ingredients

Dry Ingredients

  • 2 cups rolled or quick-cooking oats
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 teaspoon cinnamon

Wet Ingredients

  • 3/4 cup butter (room temperature)
  • 1 egg
  • 1 egg yolk
  • 1 teaspoon vanilla extract

Sugars

  • 1/3 cup sugar
  • 1/2 cup brown sugar

Fruit

  • 1 cup fresh blueberries


Instructions

  1. Cream the Butter and Sugars: In a large bowl, beat the butter with both sugars until creamy and fluffy, ensuring a smooth and light mixture that will give your cookies a tender texture.
  2. Add Eggs and Vanilla: Incorporate the egg, egg yolk, and vanilla extract into the butter mixture, mixing thoroughly until fully combined for even flavor distribution.
  3. Mix Dry Ingredients: In a separate bowl, combine flour, oats, baking powder, baking soda, salt, and cinnamon. Gradually add this to the wet mixture and mix until just combined to avoid overworking the dough.
  4. Fold in Blueberries: Gently fold in the fresh blueberries, being careful not to crush them to maintain their shape and prevent the dough from becoming too wet.
  5. Form Dough Balls: Using a #20 cookie scoop or approximately 3 tablespoons, portion out dough balls and place them on a baking sheet lined with parchment paper, spacing them to prevent sticking.
  6. Bake the Cookies: Bake in a preheated oven at 350°F (175°C) for about 12 minutes, or until the cookies are golden brown around the edges, indicating they are perfectly baked.
  7. Cool the Cookies: Remove from the oven and allow the cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely, ensuring they set and firm up.

Notes

  • For softer cookies, slightly underbake by removing them from the oven a minute earlier.
  • Use fresh blueberries to prevent excess moisture that frozen berries might add to the dough.
  • If you prefer, substitute brown sugar with coconut sugar for a different flavor profile.
  • Store the cookies in an airtight container at room temperature for up to 5 days.
  • These cookies can also be frozen; thaw at room temperature before serving.
