Keto Layer Cake – Guide to Making a Delicious Low-Carb, Multi-Layer Cake

Baking a cake on a keto diet? That may sound impossible, but trust me, it’s not. You can enjoy a beautiful, multi-layer keto cake that’s both delicious and low in carbs. Keto doesn’t mean you have to miss out on the fun stuff, like a luscious slice of cake to celebrate a birthday, anniversary, or simply a Tuesday. This guide will show you exactly how to make the ultimate keto layer cake—moist, fluffy, and loaded with flavor, all without breaking the carb bank.

Let’s get started!

What You Need to Know Before Baking a Keto Layer Cake

The main challenge with keto baking comes down to the ingredients. Traditional cakes rely on flour, sugar, and other high-carb items that are a no-go for keto. But, thanks to some nifty substitutes, you can whip up a cake that’s just as good without the carbs. We’ll be using almond flour, coconut flour, and keto-approved sweeteners like erythritol or monk fruit. These swaps keep our cake in line with keto guidelines while still giving us that satisfying cake texture.

Another thing: Keto cakes can be a little trickier in terms of consistency. Almond flour is heavier than regular flour, so your batter might feel a little thicker. Don’t worry if it’s not as light and fluffy as traditional batter. Trust the process—it will bake up beautifully!

Ingredients to Stock Up on

To make the perfect keto layer cake, you’ll need a combination of pantry staples and keto-friendly baking items. Here’s a list to make sure you’re set before you start:

  • Almond flour: This is your main flour substitute. It’s nutrient-dense, gluten-free, and low-carb.
  • Coconut flour: Helps to absorb moisture and keeps the cake fluffy.
  • Baking powder: Don’t skimp here. This helps the cake rise.
  • Eggs: Essential for structure and moisture.
  • Butter or coconut oil: Adds richness and flavor. Keto diets love fat!
  • Keto sweeteners: Erythritol, monk fruit, or stevia are great substitutes for sugar.
  • Unsweetened almond milk: Keeps the cake from drying out.
  • Vanilla extract: For that extra hit of flavor.
  • Heavy cream: You’ll need this for the frosting.
  • Cacao powder (optional): If you’re a chocolate lover, this is a must.
  • Cream cheese: Because we all know a keto cake isn’t complete without some cream cheese frosting.

Step-by-Step Recipe for a Keto Layer Cake

Let’s get into the fun part—making the actual cake. This recipe will make a 4-layer cake, but you can always adjust depending on how many layers you’re in the mood for. The more, the better!

For the Cake:

Ingredients:

  • 3 cups almond flour
  • 1/4 cup coconut flour
  • 1 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1 cup erythritol (or your preferred keto-friendly sweetener)
  • 5 large eggs, at room temperature
  • 1/2 cup unsalted butter, melted
  • 1 cup unsweetened almond milk
  • 2 tsp vanilla extract
  • Optional: 1/4 cup unsweetened cocoa powder (for a chocolate layer)

Instructions:

  • Preheat the oven: Heat your oven to 350°F (175°C). Grease and line four 8-inch round cake pans. If you don’t have four pans, no worries! You can bake in batches.
  • Mix the dry ingredients: In a medium bowl, whisk together the almond flour, coconut flour, baking powder, baking soda, and salt. Set aside.
  • Cream the wet ingredients: In a large bowl, beat the eggs with the melted butter, erythritol, and vanilla extract. Make sure the butter isn’t too hot or it’ll scramble your eggs! Then, slowly add in the almond milk.
  • Combine the two: Slowly add the dry ingredients into the wet, mixing until combined. Don’t over-mix; we’re just looking for everything to come together.
  • Create layers: If you want different flavors for each layer (like vanilla and chocolate), divide the batter into two bowls. In one bowl, add the cacao powder to create the chocolate batter. Now you’ve got two flavors to alternate between layers.
  • Bake: Pour the batter evenly into your pans. Bake for about 18-20 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

For the Keto Cream Cheese Frosting:

Ingredients:

  • 8 oz cream cheese, softened
  • 1/2 cup unsalted butter, softened
  • 1/2 cup powdered erythritol
  • 1 tsp vanilla extract
  • 1/4 cup heavy cream (for extra creaminess)

Instructions:

  • Beat the cream cheese and butter: In a large bowl, beat the softened cream cheese and butter together until smooth and creamy.
  • Add the sweetener and vanilla: Slowly beat in the powdered erythritol and vanilla extract.
  • Adjust texture: If the frosting feels too thick, add heavy cream, one tablespoon at a time, until you reach the desired consistency.
  • Chill: Let the frosting chill in the fridge for about 15 minutes before using. This makes it easier to spread between the layers and on top of the cake.

Assembling Your Keto Layer Cake

Now that your cakes are cool and your frosting is ready, it’s time to assemble this keto masterpiece.

  • Level the cakes (optional): If your cakes have domed a bit, use a serrated knife to gently level them. This makes the layers stack more evenly.
  • Frost between layers: Place the first cake layer on your serving plate and spread a generous amount of frosting over the top. Repeat with the remaining layers.
  • Frost the sides and top: Once all layers are stacked, frost the sides and top of the cake. Feel free to get creative here! You can use a piping bag for a more decorative look or keep it rustic with a knife.
  • Decorate (optional): If you want to take it up a notch, sprinkle the cake with a few keto-friendly chocolate chips, some unsweetened shredded coconut, or even fresh berries like raspberries or blackberries. Just be careful with your toppings so they stay within the keto guidelines.
  • Chill before serving: Keto cakes tend to hold together better when they’re chilled, so pop the cake in the fridge for about 30 minutes before serving. This also helps the frosting set.

Flavor Variations and Add-ons

One of the best things about a multi-layer cake is the ability to experiment with different flavors. You can go beyond vanilla and chocolate if you’re feeling adventurous. Here are a few ideas to spice things up:

  • Coconut Layer: Add a teaspoon of coconut extract and some shredded coconut to one of the layers for a tropical vibe.
  • Lemon Layer: Add the zest of a lemon and a teaspoon of lemon juice to the batter for a fresh, zesty flavor.
  • Mocha Layer: Mix a tablespoon of instant coffee powder into the chocolate layer to create a rich mocha taste.

Feel free to mix and match these flavors! A keto cake should never be boring, right?

Keto-Friendly Tips and Tricks

Keto baking can be tricky at first, but with a few tips, you’ll become a pro in no time:

  • Measure flours carefully: Keto flours like almond and coconut flour are more absorbent than regular flour, so make sure you’re measuring accurately. Too much can make your cake dry and crumbly.
  • Let your cake rest: Keto cakes can be a little more delicate than traditional cakes, so letting the cake cool completely before frosting helps it firm up.
  • Don’t overbake: Keto cakes are prone to drying out if baked for too long. Start checking for doneness a couple of minutes early, and pull them out when they’re just done.
  • Sifting matters: For a smoother cake texture, sift your dry ingredients. Almond flour, in particular, can sometimes clump together.
  • Use room temperature ingredients: Cold eggs or butter can affect the final texture of your cake. Let everything come to room temperature before you start mixing.

How Many Carbs in a Keto Layer Cake?

A regular slice of cake can set you back upwards of 40 grams of carbs (ouch!). But with this keto layer cake, you’re looking at just 3-4 grams of net carbs per slice. Keep in mind that the exact carb count will vary depending on the specific ingredients you use, but if you’re sticking to keto-friendly sweeteners and flours, you’re in the clear.
