For an added treat, serve with a scoop of vanilla ice cream on the side or drizzle with chocolate sauce for extra indulgence.
How to store Brown Butter Brookies
To store leftovers, allow them to cool completely. Place the brookies in an airtight container at room temperature for up to four days.

Tips to make Brown Butter Brookies
- Make sure to watch the butter closely while browning to prevent it from burning. The butter should turn a deep golden brown and smell nutty.
- Use good quality chocolate chips for the best flavor.
- Do not overmix the batter once you add the dry ingredients to keep the brookies soft and chewy.
- Feel free to add nuts or other ingredients like caramel bits to customize the flavor.
Variation
You can try different flavors of chocolate chips, such as dark chocolate or milk chocolate. Adding a sprinkle of sea salt on top before baking can enhance the flavor even more. For a festive twist, consider adding peppermint extract or crushed candy canes during the holidays.
FAQs
What is brown butter?
Brown butter is made by cooking regular butter until the milk solids turn brown and develop a nutty flavor. It adds richness to baked goods.
Can I use margarine instead of butter?
While margarine can be used, it will not give the same rich flavor as brown butter. It’s best to stick to real butter for this recipe.
How do I know when the brookies are done baking?
They are done when a toothpick inserted in the center comes out clean or with a few moist crumbs. Avoid overbaking to keep them soft and chewy.
