Why Use Brown Butter
Brown butter is an amazing ingredient. It adds a rich, nutty, caramelized flavor that you just can’t get with regular butter. Butter is composed or fat, milk solids and water. When butter is heated it separates into water and milk solids. The water evaporates (it’s about 22%) and the remaining solids 78% milk solids starts to caramelize which creates this beautiful golden dark brown butter. It is very similar to ghee.
This is perfect for baked goods like cookies to add deep, rich, caramelized flavor, intensifying the flavors of cookies, just the thing we need in this recipe.
Here’s how to make it. Add the butter to a small saucepan over medium heat, stirring occasionally, until it starts to melt and foam. Continue to stir until you see the milk solids settle to the bottom and begin to turn a toasty brown. Whisk in 2 tablespoons of milk until combined. Take it off the heat and place it in the freezer for 10 minutes to cool down.
You want the brown butter soft for this recipe. It should be soft like it normally is at room temperature before you use it!




Helpful Tips
- Make sure the egg is at room temprature.
- Take them out of the oven when they still look slightly underdone: This tip applies to any cookie recipe. There is enough residual heat in the pan that will continue cooking the cookie. As the cookie cools the cookie dough results crispy on the outside, but still tender in the center. So don’t bake your cookies too long!
- Bake cookies on the top rack of your oven: The bottom part of the oven is hotter and make risk burning the cookies. The tops brown quicker, giving you that golden cookie look out of the oven.
