GF very fluffy yellow sponge cake

Ingredients (for 4 small portions – to be served accompanied with sth more like fruits or a cream OR 2 big portions)

• 1 Egg separated in yolk and egg white
• some drops of white vinegar or lemon
• 25 gr powdered sugar
• 2gr vanilla sugar or zest of 1/5 orange
• 15 gr. rice flour
• 4 gr. corn starch
• Pinch of salt
• 8ml milk
• 5 ml vegetable oil

Steps

• Preheat the oven in 160 degrees
• Whisk the egg white with the vinegar and before it ends up in stiff peaks add all the sugar and the vanilla sugar
• Add the yolk and mix well
• Add the rice flour and the cornstarch together with the salt. Ideally you want to pass the flours through a strainer, so the your mix doesn´t become lumpy
• In the end add the milk and the oil
• Butter a cake form of 14 or 15cm. I used here a 15cm baking pan.
• Bake for around 30 minutes till it gets nice golden brown on top (start checking a bit before cause this timing is for my oven!)

This cake for those ingredients is very thin but fluffy! You can double the ingredients or make them in a smaller baking pan.
