Preheat the oven to 180°C and line baking paper on the bottom of a large round cake tin. Grease the sides of the cake tin to ensure that the cake won’t stick when it comes out of the oven.

In a big bowl add the sugar, olive oil, flax egg, lemon juice, lemon zest and vanilla essence. Using an electric mixer on high speed, blend until creamy and light.

Add the grated carrots, almond meal, flour, salt and baking powder and mix on a slow speed or with a spatula.

In a separate bowl, add aquafaba and cream of tartar and whip on high speed with a clean mixer until the aquafaba forms stiff peaks. It should have a similar look and feel to whipped egg whites.

Once the aquafaba has been whipped, gently fold into the cake mixture with a spatula. Try to keep as much air and lightness to the batter as possible by mixing only until it has just combined do not over-mix at this stage or you'll only be knocking air out of the batter.

Pour the batter into the greased cake tin and bake it for one hour at 180°. To check if the cake is done, insert a baking needle or skewer. If it comes out clean, the cake is done. The cake should also bounce back a little to the touch and be pulling inwards from the edges of the tin.

After the cake has cooled completely, put it in the fridge to rest for a while. It can be decorated and served immediately however this recipe tastes best from the second day onwards because the flavours continue to develop in the fridge and it will become even more moist and delicious.

To make the marzipan carrots, add a little more than ¾ of the marzipan to a bowl together with a drop of yellow and a drop of red food colouring. Knead the marzipan and adjust the colouring if necessary until you’re happy with the orange colour.

To a separate bowl, add the remaining marzipan together with a drop of yellow and a drop of blue food colouring and knead until the marzipan turns an even bright green colour.

To form the carrots, roll the orange marzipan into a carrot shape on a surface dusted with icing sugar and add a small roll of green marzipan to decorate the top end.

To make the glaze, add the icing sugar and lemon juice to a bowl and mix thoroughly until it forms a smooth, shiny icing. If it is too dry, carefully add more lemon juice but be careful not to thin out the mixture too much

Pour the glaze on top of the cake and decorate with the marzipan carrots.
