Want to wow the low carb Easter bunny? Serve him a slice of of this moist lemon speckled keto Easter cake! A lemon coconut sponge layer cake is filled with sugar free lemon curd and covered with a keto Swiss meringue butter cream. Speckled for an Easter egg effect.
We topped this lemon Easter cake with toasted coconut and made sugar free white chocolate egg shells but feel free to serve it plain or add your own flourish! Either way, it tastes great. Baked with coconut flour this lemon cake is also gluten-free.
How to make a speckled keto Easter cake
The speckling effect on the cake frosting is simply a mixture of cocoa powder and vanilla (you could use water) which is flicked onto the cake using the ends of a small paint brush. If you don't have a paint brush, a pastry brush will work too.
Keto Swiss Meringue Frosting
For this keto Easter cake, I wanted to try a thicker frosting than a buttercream and made an easy Swiss meringue frosting.
Swiss meringue buttercream is a silky and creamy frosting that is made with egg whites, low carb sweetener and butter. A perfect low carb frosting! The egg whites and low carb sweetener are whipped in a bain-marie into stiff peaks.
Once cooled, the butter is added and the whipping recommences. The mixture gives a slight curdled appearance due to the added fat, but you continue to whip until the mixture emulsifies for a creamy soft frosting.
The low carb sweetner
For both the cake and frosting we used allulose sweetener as this dissolves well with no gritty aftertaste. If you don't have allulose, try monk fruit or erythritol. For the frosting, we recommend that the sweetener is powdered for ease of dissolving.
The white chocolate keto Easter eggs
Using a silicone mini egg mold we make the egg toppings with a sugar free white chocolate recipe. The white went well with the yellow cake colour and they could be filled with a ganache or mousse too.
For the white chocolate we used:
- ¼ cup allulose sweetener
- ½ cup coconut milk powder
- ½ cup cocoa butter
The sweetener and milk powder are mixed together. The cocoa butter is melted in a bain marie, removed from the heat and the dry mixture stirred thoroughly into it.
The white chocolate mixture is then spooned into a silicone egg mold and placed in the freezer to firm until ready for use.
Change the colour of the cake to a pastel pink, green or blue. We liked the yellow to match the lemon flavour.

If you wish to replace the coconut flour with almond flour, reduce the eggs to 8 and increase the flour volume to 4 cups. The baking time should be about the same but check the sponges after 30 minutes.
