Can You Have Cake on Keto?
Yes, you can. But unfortunately, not all cakes are keto-friendly. If you want to make a keto cake for a birthday or simply are missing this flavor and want to enjoy such a dessert, you can definitely make a low-carb cake yourself at home.
It's possible to make a low-carb alternative for almost any cake flavor, including a keto white cake (scroll down for the recipe). All you need to do is choose the right ingredients to cut down on carbs (use coconut flour or almond flour).
Keto White Cake Ingredients

If you're busy and don't have much time to gather a lot of ingredients and really want to make a keto vanilla birthday cake, then I recommend you use a ready-made, store-bought low-carb cake mix for your cake. This will help you cut down on some time, and the cake itself will turn out healthy and incredibly delicious, just like the traditional white cake.
To make this low-carb white cake, you need to prepare the following:
- Cake batter: Lakanto Keto Cake Mix (this is the basis for your white cake). You'll need only one cake mix, and then once the cake is baked, you can simply cut it in half (also, for the cake base, you'll also need some eggs, water, melted butter, and vanilla extract).
- Frosting: I used this ready keto vanilla frosting for this recipe. It's keto-friendly and sweetened with allulose, which is perfect for keto.
- Cake filling: For the cake filling, you'll need some cream cheese, heavy cream, xanthan gum, strawberries, and powdered sweetener (for example, Swerve confectioners or monk fruit). If you want, you can skip the strawberries; this will cut down the number of carbs even more. And as the sweetener, I used powdered erythritol (but you can use whatever keto-friendly sweetener you prefer).
How to Make Keto White Cake
It's very easy to make this keto white cake. Basically, the whole cooking process consists of the following steps:
- Bake the cake: you'll need to mix all of the ingredients for the cake base together with the cake mix and then put the dough in a cake pan and bake it in your oven until ready.
- Prepare the filling: for this keto pound cake, I decided to make a filling from scratch, and to make it taste even better, I added some strawberries to it. If you want to do the same way, you should first simmer the strawberries in the pan for a few minutes together with the sweetener and wait for it to cool down. Then using a mixer, beat the heavy cream until peaks form, then add the cream cheese and strawberries.
- Assemble: once you've got that ready, you'll need to cut the baked keto vanilla cake in half. Then place the filling on top of one part of the cake, spread it around, and cover it with the other cake layer. Then use the frosting to frost your cake. Optionally, you can decorate the top of the cake with strawberry slices.
Storing Instructions

You can store this low-carb white cake in your refrigerator for 3 to 4 days if it is already assembled. Or, if you want, you can bake the cake in advance and wrap it up in food wrap. This way, it will last a bit longer.
Also, you can freeze this keto white cake. But my recommendation is to freeze it without assembling it since the frosting and the filling contain dairy ingredients that don't freeze well.
