Preheat the oven to 160 degrees. In a jug, whisk the eggs and granulated sweetener until fluffy.
Pour into Easter egg shaped silicone moulds. This made 10 in the mould we used but will depend on the shape and size of your mould. Do not fill completely to the top as the cakes will rise in the oven.
Bake for 20 minutes until cooked through and golden. Take out of the oven and leave to cool in the silicone mould for 5 minutes before carefully pushing them out onto a wire rack.
