How to Make the Recipe
Now, let’s get to the fun part! Here’s how to make these scrumptious cookies:
- Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or grease them lightly.
- Cream the butter and sugars in a large mixing bowl using an electric mixer for 3-4 minutes until light, fluffy, and pale.
- Add the wet ingredients: Beat in the egg, milk, vanilla extract, and cinnamon until smooth and well combined.
- Mix the dry ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add to the wet mixture, mixing on low until just combined.
- Fold in oats and walnuts: Gently mix in the oats and chopped walnuts until evenly distributed.
- Shape and bake: Drop dough by rounded tablespoons (or use a cookie scoop) onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 12-15 minutes until the edges are golden brown and the centers are slightly soft.
- Cool: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Pro Tips for Making the Recipe
Here are some helpful suggestions to ensure your cookies turn out perfectly every time:
- Make sure your butter is at room temperature for easy creaming.
- Don’t overmix the dough once you add the flour; this will keep your cookies tender.
- If you prefer Crispy Oatmeal Cookies, bake them a minute or two longer.
- Feel free to add chocolate chips or dried fruit for a creative twist!
How to Serve
These cookies are delightful on their own, but you can elevate your serving game by:
- Pairing them with a glass of cold milk or a warm cup of tea.
- Serving them as part of a dessert platter with other Creative Cookies.
- Using them as a topping for ice cream for a delicious sundae!
Make Ahead and Storage
If you want to prepare these cookies in advance, here are some tips:
- You can make the dough ahead of time and refrigerate it for up to 3 days. Just scoop and bake when you’re ready!
- Baked cookies can be stored in an airtight container at room temperature for up to a week.
- For longer storage, freeze the cookies in a single layer, then transfer to a freezer bag. They can last up to 3 months!
