• Baking Powder – Helps cookies rise and become fluffy.
• Baking Soda – Balances pH to help cookies spread.
• Ground Cinnamon – Infuses warmth and flavor depth.
• Salt – Enhances the overall flavor profile.
• Eggs – Acts as a binder and provides moisture.
• Pure Vanilla Extract – Adds aromatic sweetness to the chewy blueberry oatmeal cookies.
• All-Purpose Flour – Contributes to the cookie structure; avoid overmixing to keep cookies tender.

Step‑by‑Step Instructions for Chewy Blueberry Oatmeal Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This is crucial for achieving the perfect chewy texture in your Chewy Blueberry Oatmeal Cookies. As the oven warms, it will ensure even baking and that delightful aroma fills your kitchen as the cookies bake!
Step 2: Cream the Butter and Sugars
In a large bowl, cream together the softened unsalted butter, brown sugar, and white sugar until the mixture is smooth and fluffy. This process usually takes about 2–3 minutes using an electric mixer, which will incorporate air for a lighter cookie. Once well combined, add the baking powder, baking soda, ground cinnamon, and salt, mixing until everything is fully integrated.
Step 3: Incorporate the Eggs and Vanilla
Next, add in the eggs one at a time, mixing after each addition until the batter is light and creamy. Then, pour in the pure vanilla extract, stirring gently to incorporate it throughout the dough. These ingredients will add moisture and a wonderful flavor to your Chewy Blueberry Oatmeal Cookies.
Step 4: Fold in the Dry Ingredients
Gradually add in the all-purpose flour, carefully folding it into the wet mixture just until combined. Avoid overmixing to keep the cookies tender. Once the flour disappears, you’re ready to take the next step toward cookie bliss!
Step 5: Add the Oats and Chill the Dough
Stir in the old-fashioned rolled oats until evenly distributed throughout the dough. To improve the cookie’s texture and make handling easier, cover the bowl with plastic wrap and refrigerate the dough for about 30 minutes. This chilling period will help your Chewy Blueberry Oatmeal Cookies hold their shape when baking.
Step 6: Mix in the Blueberries
After the dough has chilled, gently fold in the frozen blueberries straight from the freezer. Be careful not to overmix, as this can break apart the blueberries and turn your cookies a lovely purple color. You want those bursts of blueberry flavor in your cookies!
Step 7: Scoop the Cookie Dough
Using a cookie scoop or spoon, portion out balls of dough and place them on a lined baking sheet, ensuring they are spaced about 2 inches apart. This spacing is essential to allow for spreading as the cookies bake, creating the perfect chewy texture.
Step 8: Bake to Perfection
Slide the baking sheet into your preheated oven and bake the cookies for approximately 15 minutes. Keep an eye out for golden-brown edges while the centers still appear soft—this is the key to making the ultimate Chewy Blueberry Oatmeal Cookies!
Step 9: Cool and Enjoy
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 10-15 minutes. This cooling time allows them to set properly before transferring them to a wire rack. Enjoy the warm, chewy goodness of your homemade cookies!
