00:00Hi everyone, today we are making a light and fluffy vanilla sponge cake
00:04This one of my favourite recipe
00:07It goes well with a variety of fillings
00:09There are a few tips to make this fluffy sponge cake
00:12And I will show you how it's done
00:14So let's get started
00:30Preparation
00:38Place a piece of parchment paper on the bottom of the pan
00:41Don't grease or use a non-stick pan
00:43Essentially your sponge cake batter is using the sides of the pan to help it climb up so it doesn't collapse
00:50Make sure all utensils clean and grease free
00:53Any residue of fat will prevent egg whites from beating up properly
00:57The acid in lemon juice or vinegar help remove grease
01:01Remember preheat the oven before you start
01:03Don't let the batter wait too long, there will be a risk of the batter collapsing
01:08It is important to use fresh eggs that are room temperature
01:11Egg whites are most effective when beaten at room temperature to stiff peaks
01:16When eggs are cold, they will be difficult to expand
01:20Fresh eggs have round egg yolks and thick egg whites
01:23If the egg whites runny and the yolk is flat, it means the eggs is no longer fresh
01:28Eggs are easier to separate when cold
01:30So do this when you take them out of the fridge
01:33Then let them come to room temperature
01:39Prepare the dry ingredients in advance
01:42Combine the flour and baking powder
01:46And for the wet ingredients, mix room temperature milk along with oil and vanilla extract
01:54Set aside
01:58We will start by beating the egg whites over high speed for about 30 seconds until foamy
02:08You can add lemon juice, white vinegar or cream of tartar
02:11This acid will help stabilizing the egg whites
02:14Continue beating for another 30 seconds
02:17Then I will add sugar in 3 batches every 1 minute
02:48Once all the sugar is added, continue beating on high speed until stiff peak for about 3 minutes
02:55The mixture will gradually thicken and look shiny
02:58When the mixture is lifted and the tip like this is not dead yet
03:02Whip again for a while
03:13Now the tip is pointed like this, it's called a stiff peak
03:17That's what we are looking for
03:18Now I will pour in the egg yolks using a hand whisk
03:22Stir gently until evenly mixed
