Flavor Substitutions

If you want to change the flavor of the cake, you can easily do so by swapping out the vanilla extract for your favorite extract.

Some great substitutions are almond extract, lemon extract, or orange extract.

These extracts will give the cake a different flavor profile giving you many variations.

Best Sugar Substitutes For A Keto Birthday Cake

When it comes to choosing your sweetener for this homemade sugar-free birthday day cake recipe, I have several low-carb options that work well.

I really like Lakanto Monk Fruit Sweetener because the texture is spot on and because there is barely any aftertaste.  Plus it uses only natural ingredients.

This is a great one especially if you are new to sugar substitutes because it mimics sugar the most in my opinion.

I’m also partial to Swerve an erythritol blend. Although you should keep in mind that it does have a bit more of a cooling aftertaste that some people dislike. 

Alternatively, you could also use a stevia and erythritol-based brand like Pyure.  This is if you prefer to use stevia in your baked goods. If you go this route you need to reduce the amount by half since it is twice as sweet. 

Lastly, if you can’t easily find a more natural sugar substitute you can also use Splenda with great success.

I know not everyone would agree with me here and I respect that but in my book, it’s still better than regular sugar.

However, when it comes to the keto vanilla frosting you will have to use a confectioner’s sugar substitute. Both Lakanto and Swerve have great ones. 

How To Make A Keto Vanilla Birthday Cake

Here’s how to make a delicious and sugar-free birthday cake that everyone will love! I am including instructions on how to bake it in a 13×9 pan and a 3-layer cake baked in 6-inch cake pans so you have options.

Instructions For A 13X9 Inch Cake

You’ll start by preheating the oven to 350°F. Grease a 13×9-inch baking pan with butter.

Then in a medium bowl, combine the sifted almond flour, baking powder, and salt. Then set it aside.

Next, in a large bowl, use an electric mixer, or stand-up mixer and cream the butter with the granulated sugar substitute until the mixture is light and fluffy, and well incorporated.

Now add the softened cream cheese and vanilla extract and continue to process until they are well mixed.

Add the eggs one at a time, making sure to mix well after each addition.

Next, add the dry ingredients to the wet ingredients and mix well until the batter is fully combined.

At this point, you’ll want to fold in two tablespoons of sugar-free sprinkles for a funfetti cake.

Spread the batter into the prepared pan and bake for 30-35 minutes, or until golden brown on top and an inserted toothpick comes out clean.

Instructions For A Layer Cake

Preheat the oven to 350°F. Generously grease with butter and line the bottom of the (3) 6-inch cake pans. with parchment paper.

In a medium bowl, combine the sifted almond flour, baking powder, and salt

In a large bowl, using an electric mixer, cream the butter with the granulated sugar substitute until the mixture is light and fluffy, and well incorporated.

Add the cream cheese and vanilla extract and mix well. Add the eggs one at a time, making sure to mix well after each addition. Add the dry ingredients to the wet ingredients and mix well until the batter is fully combined.

At this point, you’ll want to fold in two tablespoons of sugar-free sprinkles for a funfetti cake.

Spread the batter evenly into the prepared cake pans. Bake for 25 to 25 minutes, until golden brown on top. The cakes will be done once a toothpick inserted in the center comes out clean.

Cool the cakes on a baking rack for 10 minutes before removing them from the pans. Then cool for another 25 minutes on a rack until fully cooled before frosting.

Store any leftovers in the refrigerator for up to 5 days or freeze for up to 3 weeks.

Keto Vanilla Cream Cheese Frosting

To make the vanilla keto cream cheese frosting, mix in a large bowl using an electric mixer the softened cream cheese and butter for about 5 minutes until it is light in color. To this mixture add the vanilla extract and mix well.

Next, add the powdered sugar-free substitute a few tablespoons at a time at a low setting until all the sweetener has been added to the mixture.

Then mix at medium-high and add a couple of tablespoons at a time for up to 1/4 cup of heavy cream and beat until well incorporated. Start with 2 tablespoons of cream and add more if needed.

Frosting A 13×9 In Cake

Spread the frosting over the cooked cake. Be sure the cake is fully cooled before frosting.

Next, add the sugar-free sprinkles over the top of the cake.

Frosting The Layer Cake

It’s crucial to frost the cake layers only after they are completely cooled otherwise the frosting will melt.

Before frosting brush off any loose crumbs and then spread 1/3 cup of frosting over the top of the first layer. Spread evenly from the middle to the edges of the cake.

Then add the second layer, being sure to align the edges. Place rounded side down, on top of the first layer, and press gently the cake layer in place.

Add another 1/3 cup of frosting over the top of the second layer spreading evenly and gently pushing the frosting toward the cake edges. Try to keep the frosting level so that each layer is consistent and you have even layers when you cut the cake.

Next, add the final third layer rounded side down and once again spread 1/3 cup of frosting over the top spreading to the edges of the cake.

Once the inside cake layers of frosting are done, it’s time to make a crumb coat of frosting. A crumb coat layer is simply a thin layer of frosting over the side and top of the cake that helps seal in crumbs before adding the rest of the frosting.

To do so, use a spatula to spread a small amount of frosting across the top of the cake, then scoop about 2 tablespoons of frosting at a time onto the edge of the spatula and gently smear an even coat onto the sides of the cake and cover the entire cake.

At this point, I like to place the cake in the freezer for about 15 minutes to ensure the crumb coat adheres to the cake making it easier to frost.

Once the cake has chilled, apply a thick layer over the crumb coat. Start by placing 1/2 cup to 3/4 cup of frosting in the center of the cake.

Use the spatula to gently pull the frosting from the center to the edges of the cake. Then make sure to frost evenly the sides of the cake as well.

To create a smooth surface, dip your spatula in warm water, shake off the excess water and glide the bottom of the spatula until the entire surface of the cake has a smooth even finish. If you do not want a smooth cake, you can add slight swirls using the back of a spoon.
