Ultimate Keto Brown Butter Cake

Brown butter makes everything better! I mean, it truly is a game-changer. This keto brown butter cake became my family’s all-time favorite almost immediately.

And the secret was taking the time to brown the butter.

When you cook butter until the milk solids turn brown, you intensify the flavor. This adds a great depth of flavor to the cake that cannot be achieved any other way. 

This low-carb brown butter cake recipe uses both butter and cream cheese in the batter, as well as brown butter icing that soaks into the baked cake. Yum. This makes this a very moist, low-carb cake. 

The making of this brown butter bundt cake was not only a delicious treat but a stellar-looking dessert that even your non-keto folks will rave about.

I have quite a number of keto cakes that you should also check out if you are a fan of cakes doing keto.  

Low-Carb Brown Butter Cake

I knew I had a winner when my picky son, who doesn’t do keto, declared it was the best thing he’s ever tasted of mine. 

This momma lives for those compliments. Lol, I’ll convince him of this keto lifestyle, one delicious treat at a time.  

This keto bundt cake is not your average cake. Unlike some of my other cakes, which can be whipped up quickly, this recipe will require a little more time since you are not only browning the butter but also allowing it to cool until it becomes opaque again.

It’s a step that takes some time but cannot be rushed or skipped. 

Doing so will NOT produce the right texture. This extra step allows you to cream the butter and give the pound cake a fine crumb.

To save time, you might want to brown your butter a day before and let it cool in your fridge overnight.

But I promise you that it will be so worth the extra time because you will be rewarded with a rich butter-flavored keto cake that will be well-loved. 

I made this recipe with a 9.5-inch 12-cup bundt pan because it allows the cake to bake evenly on all sides and produces a lovely golden crust.

Of course, you can also make it a 12×12 pan or two 9-inch pans with excellent results. 

In some circles, this cake is referred to as Kentucky Butter Cake. I guess Kentuckians know how to use butter. But in my home, this became known as the pound cakes of keto pound cakes.

How Do You Make Brown Butter

Since the star ingredient in this low-carb cake is brown butter, it’s vital to know how to properly brown your butter.

Using a light-colored pan when browning your butter is important because you want to see the butter change colors; otherwise, you risk burning your butter, and that’s not at all tasty. 

I suggest you use a stainless steel pan because it’s light-colored and conducts heat evenly. Then, it’s just a matter of adding your butter to the pan and setting the heat to medium-low.

It’s essential to keep a watchful eye when browning your butter since the process is relatively quick.

The butter will start foaming as it cooks, so keep stirring and looking at the solids at the bottom of the pan to see how the color changes.

As it approaches the right state, you’ll notice less foaming and that the butter starts to have a distinct nutty smell and a lovely amber-brown color.

Once the brown butter achieves a light brown tone, it’s key to remove it from the heat, transfer the butter to a heatproof bowl, and allow it to cool in the refrigerator.

How To Make A Keto Brown Butter Cake

The only tools you’ll need are an electric mixer, a bowl, a bundt pan, and a stainless steel pan to brown the butter in. 

Let me also mention that the type of bundt pan you use is important. Not all are created equal, and after a while, bundt pans don’t release the cakes well, so investing in a good one is worth the tiny investment.

I use CasaWare’s brand because it has a granite ceramic that makes for easy-release baking. 

Traditionally, brown butter cake calls for buttermilk, but buttermilk is way too high in carbs to make it into this recipe.

However, I make my own buttermilk by adding a little white vinegar to room-temperature heavy whipping cream.

Again, don’t skip this step since it adds yet another layer of flavor to this keto brown butter cake.
