What is Brown Butter?

Browned butter is just regular butter that undergoes a cooking process that turns the milk solids into deep golden brown flecks and develops a nutty aroma and flavor. As it cooks, the water evaporates, and the Maillard reaction occurs as the milk solids chemically change and become little brown bits at the bottom of the pan. You’ll see it foam and sizzle, and then it will start to smell warm and toasty. The browning process of butter adds complexity to the taste and gives it a caramel flavor.

Ingredients for this brown butter frosting recipe

Here are the ingredients you will need to make this brown butter buttercream frosting. Scroll down to the recipe card at the bottom of the page for the detailed ingredient measurements. 

• Unsalted Butter: is the star of the frosting that gets altered to set it apart from regular buttercream. You will need to measure out two separate amounts.
• Powdered Sugar: sweetens the frosting and gives it structure.
• Cold Heavy Cream: adds creaminess and helps thin the frosting to your desired consistency.
• Vanilla Extract: enhances the overall depth and nutty flavor.
• Salt: balances the sweetness. We use unsalted butter instead of salted butter so that we can add the salt in separately and control the amount better.

How to make this rich brown butter frosting recipe

This is how you can make the best brown butter buttercream icing. Make sure to scroll down to the recipe card at the end of this post for the prep time, total time, and full step-by-step instructions! 

1. Melt butter in a small saucepan over medium heat. As the butter melts, stir frequently as it foams and begins to brown. Once the butter browns, remove it from the heat and transfer it to a heat-safe bowl. Let the butter cool at room temperature, then refrigerate the cooled brown butter until it firms up.
   • You can also cool the butter by stirring it continuously in an ice water bath for 5-10 minutes.
2. In a large mixing bowl, beat the chilled browned butter and the softened regular butter together using a hand mixer or in the bowl of a stand mixer on medium-high speed with a paddle attachment until the mixture is light, fluffy, and smooth.
3. Slowly add the sifted powdered sugar to the brown butter mixture with the electric mixer on low speed until fully incorporated. Stir in the vanilla extract and salt.

1. Pour the cold heavy cream into the large bowl a tablespoon at a time until you get the right consistency, whipping at medium speed until the frosting is fluffy and spreadable. If the frosting feels too thick, add more cream as needed. For a thicker consistency, mix in a bit more powdered sugar.
2. I like to use this flat beater to reduce the amount of bubbles in the icing.

Tips and Tricks for the best results

• Sift your powdered sugar to prevent lumps and ensure an ultra-smooth finish.
• Make sure your heavy whipping cream is cold to help keep the butter stable while mixing.
• Brown butter can go from perfect to burnt very easily. Watch it closely as it cooks, stir constantly, and look for the golden color. Once it smells nutty, it’s done.

How do I store my leftover brown butter frosting?

To store, place the icing in an airtight container and put in the fridge. It should last for up to 3 days. If chilled, let it come to room temperature and re-whip briefly to restore the fluffy texture before using.

Can I freeze it?

Yes, you sure can. To do so, store it in an airtight container or freezer bag for up to 3 months. When ready to use, thaw it in the fridge overnight, and let it come to room temperature. Just know that you will definitely have to re-whip it to restore its texture.

Can I brown the butter ahead of time?

Yes! You can brown the butter in advance and store it in the fridge for up to a week. Just let it soften to room temperature before turning it into the frosting.

What if I accidentally over-brown or burn the butter?

If the butter turns too dark or smells burnt, it’s best to start over. Burnt butter will give the frosting a bitter taste rather than a toasty, nutty one.

Can I brown vegan butter?

You might be able to brown vegan butter, but it depends on the brand and what it’s made from. Some vegan butters will just melt and sizzle while others that are formulated with plant-based proteins or added solids might brown slightly and give you a more flavorful effect. Overall, it simply won’t be the same as the dairy version unfortunately.

After doing a lot of research, I saw that the Violife Vegan butter browns fairly well, so try that if you need a dairy-free option. Mix in coconut cream instead of whipped cream to get the icing light and fluffy.
