The Method for Blueberry Pistachio Oatmeal Cookies

Now that you have your ingredients and gear ready, it’s time to get baking! Follow these simple steps for perfect Blueberry Pistachio Oatmeal Cookies:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, use an electric mixer to cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This should take about 2-3 minutes.
Step 3: Add the Egg and Vanilla
Add the egg and vanilla extract to the butter and sugar mixture. Beat until well combined.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, salt, ground cinnamon, and quick oats until evenly mixed.
Step 5: Mix Dry Ingredients with Wet Ingredients
Gradually add the dry mixture to the wet mixture, stirring until just combined. Be careful not to overmix, as this can lead to tough cookies.
Step 6: Fold in the Blueberries and Pistachios
Gently fold in the fresh blueberries and shelled pistachios with a spatula, ensuring even distribution throughout the dough.
Step 7: Scoop the Dough
Using a cookie scoop or tablespoon, drop rounded balls of dough onto a parchment-lined baking sheet, spacing them about 2 inches apart.
Step 8: Bake
Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are set but still soft.
Step 9: Cool
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
