Pre heat oven to 180ºC 30 minutos.
I got this recipe from my grandmother. It is super delicious, light and has a subtle flavour. The texture is different from the traditional sponge cake, is a bit more moist and a lot more fabulous.
Start by mixing in a bowl the oil with the sugar, then add the eggs and lime zest and mix well.
In a different bowl mix the flour with the baking powder. And now the process becomes more interesting: In the first bowl (the oil mix bowl) start by adding a drizzle of the milk, followed by a spoonful of the flour mix, and whisk well. Keep on doing this until all the milk is poured and all the flour is mixed.
Add the mix in an oven mold and bake for 30 minutes.
* Optional: before putting it in the oven you can add walnuts or almonds, finley chopped, on top of the cake.
