2 cups (175g) old-fashioned rolled oats – Adds wholesome heartiness and chewiness to the cookies.
1 tsp baking soda – Helps the cookies rise beautifully for that perfect texture.
1 tsp salt – Balances sweetness and heightens the overall flavor.

How to Make Buttery Oatmeal Cookies
Follow these simple steps to prepare this delicious Buttery Oatmeal Cookies:
Step 1: Brown the Butter
Begin by placing the unsalted butter in a saucepan over medium heat. Stir occasionally until the butter melts and turns a caramel brown with a rich, nutty aroma. Be sure to keep a close eye on this, as it can quickly go from browned to burnt. Once ready, remove it from the heat and let cool slightly.
Step 2: Prepare the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, oats, baking soda, and salt. This combo will lay the groundwork for your cookie’s delightful texture. Set it aside, feeling like a confident baker already.
Step 3: Combine Wet Ingredients
In a larger bowl, whisk together the cooled brown butter, brown sugar, eggs, and vanilla extract. Aim for a smooth mixture that thickens and turns a lovely caramel color. It should feel like a magical transformation right before your eyes.
Step 4: Mix It All Together
Gently fold the dry ingredients into the wet mixture using a rubber spatula. You want to be careful not to overmix; you are creating a delightful blend, not a workout! If you’re feeling adventurous and opted for mix-ins, fold those in too at this time.
Step 5: Chill the Dough
Cover the dough and place it in the fridge for about 20 minutes. This resting period allows the flavors to meld beautifully and makes the dough easier to scoop.
Step 6: Bake the Cookies
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop the dough into 2-ounce balls and place them a few inches apart on the prepared baking sheet, gently pressing each ball down to about 1/2 inch thick. Pop the baking sheet in the oven and bake large cookies for 12-14 minutes or until golden brown edges appear. Don’t worry; the centers will look slightly puffy and pale.
Once baked, sprinkle with flaky sea salt while they’re still warm, then let cool on a wire rack for about 15 minutes. As you wait, you might want to take a moment to admire your baking masterpiece and imagine how delicious they will be!
These Buttery Oatmeal Cookies are best enjoyed fresh from the oven, paired with a tall glass of milk or a steaming cup of coffee. Each bite will remind you of those cherished moments spent with family, storytelling over cookies and laughter. Enjoy!
