1. **You will need a total of 3 or 4 organic lemons to make this whole recipe**

Make the curd first

1. Simply whisk all the ingredients together in a small to medium size pot on medium heat. You will need to whisk constantly until the curd thickens, about 6-7 minutes (if you don't whisk it constantly, the eggs will separate while cooking and you'll end-up with scrambled eggs in lemon juice. haha). Once it's cooked, remove from heat immediately and pour into a bowl or a glass container with a lid, and store in the fridge. You want this to cool down properly before using it. It will also thicken even more while cooling. You can prepare this ahead of time as it'll store well in the fridge for 4-5 days.
   

To make the cake

1. Prepare a 9" round cake pan by cutting a parchment paper round the same size as the bottom of your pan. Add a very small amount of olive oil at the bottom of the pan and spread it around using your (clean) fingers. Then put the parchment paper on top. (The olive oil will act as the 'glue' to hold the paper down while you pour the cake batter later.)
2. 
   You'll need a stand mixer or a hand-held mixer to make this cake. Beat the eggs and sugars with the whisk on high speed until it has almost tripled in volume, about 5 minutes. Quickly beat in the lemon zest, vanilla and drizzle the lemon juice while mixing (you don't want to over-mix).
3. 
   Remove the bowl (if using a stand mixer), and using a large rubber spatula, gently mix in the olive oil in 2 additions, then add half of the flour, and fold it in the egg mixture, then add the other half of the flour and fold it in again.
4. 
   Pour the cake batter into your prepared cake pan, and bake in oven at 375F for about 25 minutes, or until nicely golden on top and cooked in the middle. To test, insert a clean dry toothpick or a knife in the middle of the cake: if it comes out clean, it's cooked, if it has batter on it, it's not cooked. If so, you'll need to continue baking it and test it (in different spots) regularly every few minutes.
5. 
   While this cooks, you can make the icing. Simply beat the buttery spread with the icing sugar (1 cup at a time) in a stand mixer (or hand held mixer). Beat in the vanilla, the lemon juice and the lemon zest, and at the end, beat in a pinch of turmeric powder at a time. You do not want to use too much, otherwise it'll ruin the taste, so add a small pinch at a time, mix it in well, then taste to make sure it's ok, and add a small pinch more if you want the colour to be a bit darker, and store in a cool area or put in the fridge (make sure to take it out at least 30 minutes before using). I ended-up using 3 small pinches in mine. I wanted it to remain a delicate yellow colour. No one knew there was turmeric in it, you can't taste it. ;)
6. 
   When your cake is done, remove from heat and let cool down for a good 10 minutes, then run a knife all around the pan to make it easier to remove the cake. Put a plate on top and flip the cake pan over, so that your cake will neatly fall out on the plate. Leave the parchment paper on top to protect your cake from drying out. Let cool for a few hours.
7. 
   Once it's cooled completely, using a large bread knife, or cake knife if you have one (I don't), slice your cake in 2 equal layers.
8. 
   Mix half of the lemon curd with 1/3 of the lemon icing. Spread this mixture on your bottom cake layer, then put the top layer on top. If the curd is not thick enough, you might need to add it in 2 layers of curd and put in the fridge 10-15 minutes in between to set the curd.
9. 
   Using a butter knife or a small icing knife, spread the lemon icing on top and on the sides. It doesn't have to look perfect, you can put as much or as little as you want on it. I made a 'naked' cake to see some of the cake behind.
10. 
    Keep in the fridge until 30-45 minutes before serving. This cake tastes best at room temperature, but because the icing and curd are dairy-free, it's best to keep in the fridge so that it doesn't melt if it's too hot in the house.
11. Enjoy!
