  • 1/2 tsp salt
  • 2 large eggs
  • 1 tsp pure vanilla extract
  • 1 3/4 cups all-purpose flour
  • 2 3/4 cups old-fashioned rolled oats
  • 1 cup blueberries, frozen

  • Plastic wrap
  • Baking sheets
  • parchment paper
  • Cookie scoop
  • Wire rack

Method
 

Instructions
  1. In a large bowl with a hand mixer or in the bowl of a stand mixer, beat the softened butter, packed brown sugar, and white sugar together on medium-high speed until the mixture is light, fluffy, and pale in color. This usually takes about 2-3 minutes. Don't rush this step; creating these air pockets is key to the cookie's texture.
  2. Add the eggs one at a time, beating well after each addition until it's fully incorporated. Scrape down the sides of the bowl as needed. Once the eggs are mixed in, beat in the pure vanilla extract.
  3. In a separate medium bowl, whisk together the all-purpose flour, baking powder, baking soda, ground cinnamon, and salt. This ensures the leavening agents and spice are evenly distributed, so you don't get a pocket of salt in one cookie.
  4. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix here; stop as soon as the last streaks of flour disappear. Overmixing develops the gluten in the flour, which can lead to tough cookies.
  5. Gently fold in the old-fashioned rolled oats with a spatula. Then, add the frozen blueberries and fold them in carefully. The key is to distribute them evenly without crushing them, which would turn your entire dough a murky purple.
  6. This is a crucial step! Cover the bowl with plastic wrap and chill the cookie dough in the refrigerator for at least 60 minutes, or up to 24 hours. Chilling solidifies the butter, which prevents the cookies from spreading too much in the oven, resulting in a thicker, chewier cookie. This is especially important for oatmeal cookies.
  7. When you're ready to bake, preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper to prevent sticking and ensure even browning.
  8. Scoop rounded tablespoons of the chilled dough (a cookie scoop works great for uniform size) and place them about 2 inches apart on the prepared baking sheets. Bake for 12-15 minutes, or until the edges are golden brown and the centers look set. They might look slightly underdone in the middle, but they'll continue to bake on the hot pan.
  9. Let the cookies cool on the baking sheet for 5-10 minutes before transferring them to a wire rack to cool completely. This allows them to firm up so they don't fall apart. Once cool, they are ready to be devoured!

Notes

Do not skip chilling the dough for at least one hour; this is the secret to a thick, chewy texture and prevents the cookies from spreading. Use frozen blueberries directly from the freezer to prevent them from bursting and turning the dough purple. For best results and evenly baked cookies, use a cookie scoop to ensure they are all a uniform size.
