Take 4 eggs and separate the egg yolk and egg white in each bowl.
To the yolk, add 4 tbsp of milk and oil, with a tsp of vanilla essence.
Then add 1/4th cup of maida by sifting it with 1/2 tsp of baking powder. Finally, add 1/4th cup of sugar and beat all the ingredients well. Beat till there are no lumps seen.
Meanwhile, in the egg white, add a tsp of vinegar and 1/4th cup of powdered sugar. Beat till it forms stiff peaks.
Now add the yolk mixture to this and give a great mix. Your cake batter is ready!
On that spread the batter evenly on a baking plate and bake them at 180° C for 15-20 minutes.
Now with the baking sheet, keep the cake in a rolled state when it is warm to gain flexibility without breaking.
Meanwhile, take 500 ml of whipping cream and to this, add a cup of powdered sugar in batches while beating the cream.
When done, unwrap the cake sheet and apply the cream over. Then roll the cake again with the cream inside and refrigerate for a few hours.
When done, take them out, dust them with powdered sugar, make slices and serve!
