How to Make Brown Butter Iced Oatmeal Cookies Recipe
Step 1: Prepare the Brown Butter
Start by melting the unsalted butter in a saucepan over medium heat. Continue cooking it until it turns golden brown and smells nutty. This should take about 5–7 minutes. Be attentive to prevent burning.
Step 2: Mix Dry Ingredients
In a mixing bowl, whisk together the old fashioned oats, all-purpose flour, baking soda, ground cinnamon, ground nutmeg, and salt until well combined.
Step 3: Combine Wet Ingredients
In another bowl, beat together the brown butter (cooled slightly), light brown sugar, granulated sugar, eggs, vanilla extract, and molasses until smooth.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture. Stir until just combined; do not overmix.
Step 5: Bake the Cookies
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. Drop tablespoonfuls of dough onto the prepared sheet about 2 inches apart. Bake for 10–12 minutes or until lightly golden around the edges.
Step 6: Prepare the Icing
While cookies cool, whisk together powdered sugar, milk or cream, and vanilla until smooth. Adjust consistency as needed.
Step 7: Ice the Cookies
Once cooled completely, drizzle or spread icing over each cookie using a spatula or spoon. Let set before serving.

How to Perfect Brown Butter Iced Oatmeal Cookies Recipe
To achieve the best results with your brown butter iced oatmeal cookies, consider these helpful tips.
-
Use Fresh Ingredients: Always use fresh spices and baking ingredients to ensure maximum flavor and texture.
-
Brown the Butter Carefully: Pay attention while browning the butter. It should be golden brown, which gives it a nutty flavor; don’t let it burn.
-
Chill Your Dough: For chewier cookies, chill the dough for at least 30 minutes before baking. This helps develop flavors and improves texture.
-
Measure Flour Accurately: Spoon and level your flour rather than scooping directly from the bag to avoid dense cookies.
-
Don’t Overbake: Keep an eye on your cookies while they bake. They should be lightly golden at the edges but still soft in the center when you take them out of the oven.

Common Mistakes to Avoid
Baking the perfect brown butter iced oatmeal cookies can be tricky. Here are some common mistakes to steer clear of.
