Easy Keto Butter Cake

Keto butter cake is a delightful dessert option for those following a low-carbohydrate, high-fat ketogenic diet. Its rich, buttery flavor and moist, tender crumb make it a favorite among keto dieters looking for a sweet treat that won’t kick them out of ketosis. The cake is made using almond flour or coconut flour instead of traditional wheat flour, resulting in a much lower net carb count. Sweetness is achieved through the use of keto-friendly sweeteners such as erythritol, stevia, or monk fruit, which provide the sugary taste without the high carb content. Additional ingredients typically include eggs, butter, and cream cheese, all of which contribute to the high fat content essential for a ketogenic diet.

One of the advantages of keto butter cake is its versatility. It can be enjoyed plain, with a dollop of whipped cream, or dressed up with a variety of keto-friendly toppings like fresh berries or a sugar-free glaze. Additionally, the basic recipe can be modified to include different flavors such as vanilla, lemon, or almond extract, allowing for a range of different taste experiences. This cake is not only a great option for satisfying sweet cravings on a keto diet but also for serving to guests or bringing to gatherings, as it is delicious enough to be enjoyed by those not following a low-carb lifestyle. With its delightful taste and moist texture, keto butter cake proves that you don’t have to sacrifice flavor while adhering to a ketogenic diet.

You can add flavorings (watch the carb counts), chocolate, coconut whipped cream – anything you love to make this recipe your own! This is one keto cake recipe you’ll want to make again and again – I hope you love it as much as we do.

How To Make Keto Butter Cake

This keto cake is easy to make – but there are a couple tips and tricks that will ensure the most delicious, gooey, rich, and tasty butter cake ever!

-Make sure ingredients are room temperature.

Making this cake with room temperature ingredients helps it mix much more easily and evenly – save yourself a lot of trouble, and use room temperature ingredients!

-Use a springform pan or parchment paper.

This cake is a nightmare to clean up if not prepped well – use a well greased pan, preferably springform (this makes the cake MUCH easier to release and move) when baking.

-Let the cake set.

This cake will crumble apart or deflate if you ask too much of it too soon – it needs to rest and chill after baking to set.

We like to leave it out, in the springform pans, until cool – when we then will move, slice, stack, or eat the cakes.

How To Store Keto Butter Cake

Since this cake uses keto flour replacements, it is very filling.

Almond and coconut flower fill you up much faster than wheat flour – and have many more calories.

Add eggs and cream cheese to that, and these cakes definitely eat more like a meal than a dessert!

Since we can’t ever get through much of these cakes in one sitting, it is important to store them properly for eating later.

I wrap each cake tightly in plastic wrap, and then place them in a ziploc bag to store in the fridge, or the freezer.

Cakes in the refrigerator last up to four days – and up to three months in the freezer.

To defrost, let the cakes sit in the refrigerator until soft. Microwave or bake the cakes until just warm if desired to reheat.

To Make This Easy Keto Butter Cake, You’ll Need:

-Springform pans


-Hand mixer or Stand Mixer

-Coconut oil baking spray

Keto Butter Cake Ingredients You’ll Need:

Coconut flour – Coconut flour has a slightly sweet and nutty flavor, imparting a subtle coconut taste to baked goods while providing a dense and soft texture.
Powdered erythritol – Powdered erythritol provides a sweet taste similar to powdered sugar, with a slight cooling effect in the mouth, yet it is a sugar alcohol with a negligible impact on blood sugar levels.
Baking powder – Baking powder has a neutral taste when combined with other ingredients in a recipe, but its main role is to produce carbon dioxide gas, causing the dough or batter to rise and resulting in a light and airy texture.
Beef gelatin – Beef gelatin is virtually flavorless when dissolved and mixed into recipes, but it plays a crucial role in providing structure and a gel-like consistency to various dishes.
Butter – Butter adds a rich, creamy flavor to recipes, with a luxurious mouthfeel and a slightly nutty and savory undertone, especially when browned.
Vanilla extract – Vanilla extract adds a sweet, floral, and slightly woody flavor, enhancing the overall taste of baked goods and desserts with its aromatic and complex profile.
Eggs – Eggs have a mild, savory taste, contributing richness and depth to dishes while also playing a vital role in binding ingredients together and adding moisture.
Cream cheese – Cream cheese boasts a smooth and tangy flavor, providing a luscious creaminess.
Liquid stevia – Stevia offers an intensely sweet taste without the calories of sugar, although some people may detect a slight bitter or licorice-like aftertaste at higher concentrations.

What to Enjoy with Keto Butter Cake

Keto butter cake is a delicious low-carb and high-fat dessert option for those following a ketogenic diet. When pairing sides or accompaniments with keto butter cake, it’s important to keep the macronutrient balance in mind, focusing on low-carb and high-fat options to maintain ketosis. Here are some ideas for what you can enjoy with your keto butter cake:

Whipped Cream:

  • A dollop of homemade whipped cream made with a keto-friendly sweetener can add an extra layer of richness and sweetness to the cake without adding carbs.

Fresh Berries:

  • A handful of fresh berries such as raspberries, strawberries, or blackberries can provide a burst of flavor and a slight tartness, balancing out the richness of the butter cake.

Nut Butters:

  • Drizzling some almond or peanut butter (make sure it’s sugar-free and low in carbs) over the cake can add a nutty flavor and enhance the overall taste.

Coconut Cream:

  • For a dairy-free option, you can serve the cake with a side of whipped coconut cream.

Keto Ice Cream:

  • There are several keto-friendly ice cream brands available that use sweeteners like erythritol or stevia. A small scoop on the side of your butter cake can create a delightful dessert duo.

Lemon or Berry Sauce:

  • A tart lemon or berry sauce made with keto-friendly sweeteners can add a zesty touch to the cake.

Hot Beverage:

  • A hot cup of coffee, tea, or even a keto hot chocolate can complement the buttery richness of the cake.

Keto Custard:

  • A side of keto-friendly custard made with full-fat cream and a low-carb sweetener can add a silky and decadent texture.

Spiced Nuts:

  • A handful of roasted and spiced nuts can add a crunchy texture and spiciness that contrasts well with the soft and sweet cake.

Cream Cheese Frosting:

  • If you’re feeling extra indulgent, a keto-friendly cream cheese frosting can take your butter cake to the next level.

Dusting of Cocoa Powder or Cinnamon:

  • A light dusting of unsweetened cocoa powder or cinnamon can add an aromatic touch without adding carbs.

Keto Syrup:

  • There are low-carb syrups available that can drizzle over the cake for added sweetness.

  • Add the coconut flour, erythritol, baking powder and optionally the gelatin, and combine using a spatula.
  • Set aside.
  • TOP LAYERIn a large mixing bowl, cream together the butter and cream cheese using a hand mixer.
  • Add in the vanilla extract, erythritol, stevia and eggs, and combine with the hand mixer until smooth.
  • CAKEForm the bottom layer (effectively the cake’s “crust”) into the bottom of the spring form pan using your hands. 
  • Pour the top layer on top of the crust layer and give it a few taps to release the air bubbles.
  • Bake in the oven for 30-35 minutes.
  • Your cake is ready to cool when you notice the sides are browning.
  • Cool for 15-20 minutes to let cake set before removing from pans or moving around too much.
  • Serve and enjoy!

    Where do you get Beef Gelatin?

    1. Courtney ODell says:

      Most health food stores have it in the baking aisle

      1. Lorry Norton says:

        Does it have to be beef gelatin from a health food store? Can you use regular gelatin from the grocery store?

      2. Courtney ODell says:

        To be keto some people are very strict about the source of the gelatin – but if you’re a bit more flexible with your diet, it works just fine.

    2. Marlene says:

      Amazon has it. That’s where I bought mine – lasts a long time because you only use a small amount.

    I really love this recipe, thanks for sharing this recipe.
