If you’ve never browned butter, you’re in for a real treat (literally)! It’s a secret ingredient I love for baking because it creates a rich, almost caramelized flavor like in this brown butter blueberry coffee cake.

When you brown the butter for cookies you turn the base of the recipe into a star ingredient. You caramelize the milk fat in the butter and it turns brown and creates a sweet, nutty flavor. It adds so much depth to recipes like this and brown butter banana bread.

Recipes FAQs

What does browned butter do to cookies?

Browned butter adds a rich and nutty flavor to the cookies. Brown butter is melted butter where the milk fats caramelize, so it adds that deep caramel flavor to the cookie. It also removes the water content from the butter, so it’s important to add more moisture to the dough so they don’t dry out.

Why did my brown butter cookies get hard?

Too much flour in cookie dough, or not enough moisture, results in hard cookies. Browning butter removes the water content from the dough as it cooks and evaporates, so the cookie dough needs some extra milk! Be sure to measure your flour correctly for best results.

Is light or dark brown sugar better for oatmeal cookies?

Dark brown sugar has more molasses, which gives it a richer flavor and more chew. These cookies are made to be rich and chewy, so I love dark brown sugar in oatmeal cookies. But I’ve made them with both with great results.

How do you keep oatmeal cookies soft?

Add a slice of bread to the container when you’re storing oatmeal cookies.

Expert Recipe Tips

  • Use a light pan. Brown the butter in a light saucepan so you can see the milk solids turning brown.
  • Measure correctly. Weigh your ingredients for best results or spoon and level the flour into the measuring cup. It’s my top tip for these famous pudding cookies.
  • Don’t skip the milk. Browning the butter evaporates the water content from the butter so you have to add more moisture or the cookies will be dry.
  • Chill the dough: This ensures they don’t spread in the oven and helps develop the flavor.

How to Store

Room temperature: Store leftover cookies in an airtight container at room temperature for up 1 week. Add a piece of bread in it to help they stay moist.

Freeze baked cookies: Store them in a resealable freezer bag or airtight container for up to 3 months. Thaw overnight at room temperature.

Freeze cookie dough: Skip chilling in the fridge and scoop them out into dough balls on a parchment lined cookie sheet. Freeze until solid then transfer the dough to a resealable freezer bag. Bake from frozen. Add 1-2 minutes to the bake time.
