How to Make Brown Butter Iced Oatmeal Cookies Recipe
Step 1: Brown the Butter
Start by melting the unsalted butter in a saucepan over medium heat. Continue cooking until it turns golden brown and gives off a nutty aroma. Remove from heat and let it cool slightly.
Step 2: Combine Dry Ingredients
In a mixing bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, ground nutmeg, and salt until well combined.
Step 3: Mix Wet Ingredients
In another large bowl, combine the browned butter with both sugars. Use a whisk to mix until smooth. Add in the eggs one at a time followed by vanilla extract and molasses. Mix until fully incorporated.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry ingredients into the wet mixture. Stir until just combined. Fold in old fashioned oats gently until evenly distributed.
Step 5: Bake the Cookies
Preheat your oven to 350°F (175°C). Line your baking sheet with parchment paper. Scoop tablespoon-sized amounts of dough onto the prepared sheet about two inches apart. Bake for about 10 minutes or until lightly golden around the edges.
Step 6: Prepare the Glaze
While cookies are cooling on a wire rack, combine sifted powdered sugar with milk and vanilla in a bowl. Whisk until smooth and drizzle over cooled cookies once they have set.

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 ensure your baking ingredients are fresh. Old baking soda or flour can affect the texture and flavor of your cookies.
-
Brown the Butter Carefully: Take your time when browning the butter. Aim for a golden color and nutty aroma without burning it, as this adds depth to the cookie’s flavor.
-
Chill the Dough: For thicker cookies, chill your dough for at least 30 minutes before baking. This helps prevent spreading and keeps them soft and chewy.
-
Don’t Overbake: Keep an eye on your cookies while they bake. Remove them from the oven when they are just set and lightly golden around the edges for optimal softness.
-
Sift Your Powdered Sugar: Sifting powdered sugar ensures there are no lumps in your glaze, resulting in a smooth finish over each cookie.

-
Fruit Salad: A refreshing mix of seasonal fruits adds brightness to balance the rich flavors of the cookies.
-

-
Spiced Hot Cider: Warm spiced apple cider pairs well with these cookies, enhancing their cozy spice notes during colder months.
-
Chocolate Fondue: Set up a chocolate fondue station where guests can dip fruit or even pieces of cookie into melted chocolate for extra indulgence.
-
Nutty Granola: Serve alongside homemade nutty granola as a crunchy side that complements the chewy texture of the cookies.

- Skipping the Cooling Time: Letting cookies cool before icing ensures the glaze sets properly. Don’t rush this step for best results.
