Biscuit makes a very fluffy, light cake and is perfect for a cake base. It is easy to bake and very yummy. I think North American sponge cake is similar to it, though I haven’t done that yet. This was an attempt the other day because I was looking for something to celebrate a birthday at work. So, I figured I try something new and voila, it worked perfectly.
Ingredients for the dough:
– 4 eggs
– 2 tbsp. warm water
– 1 tsp. vanilla extract
– 125g sugar
– 100g flour
– 25g corn starch
– 1 tsp. baking powder
Take the eggs and separate them. Mix yolk with half the sugar and water in a bowl, then put it aside. Take the egg white and mix it with the rest of the sugar until foamy and stiff. Take the egg white mix and carefully mix 1/3 into the egg yolk mixtures. Place the rest of the egg white mix on top. Sift flour with corn starch and baking powder and mix with the egg mixture until well combined.
Spread the dough on a baking sheet which is lined with baking paper. Try to even the dough and bake for 15 min in the preheated oven at 180°C.
Once the cake is done, place it on a tea towel which is sprinkled with sugar. (The sugar will make sure that the cake will not stick to the towel, so use a bit more.) Roll the cake into a roll and let sit to cool. While your cake cooles prepare the filling.
Ingredients for filling:
– 1/2 liter milk
– 1 package vanilla pudding Dr. Oetker
– 50g sugar
– 200g nougat
– 250g butter
Heat the milk and mix in the pudding powder and sugar. Stir until it is a firm texture. Set aside and beat the butter until foamy. Melt the nougat (I used “Ritter Sport”) and mix it, spoon by spoon, into the butter. Add the puddig, spoon by spoon, until the mix is nice and soft. Make sure that the nougat and pudding have about the same temperature. You can use a chocolate thermometer, if you have. So far, I don’t own such a fancy thing, yet. 😉
Once the cream is nice and smooth let it cool down a bit. Unroll the biscuit roll, spread 2/3 of the cream on the roll and roll it up. Take the rest of the cream and fill a piping bag. Now you can be very creative, use any tip you like and decorate the outside of your roll. (See picture for reference.)
There are other option you can do instead of nougat, for example Lemon.
Ingredients lemon filling:
– 1 package gelatine
– 3 lemons
– 125g sugar
– 250g whipping creme
I made my whipping creme from a package with powder, the amount was just right, though I could have used a bit more. Make your whipping creme the way you like, just make sure it is 250g or more. Take one lemon and zest it, all lemons get squeezed and should add up to 150ml. Mix the juice and zest with sugar and prepare the gelatine with the lemon juice according to the package. (I believe it was: mix 50 ml cold juice with powder, then heat up 50ml and mix into cold mix, let sit for a bit.) As soon as the gelatine starts to set, mix it with the whipping cream. Put your mix in the fridge which will speed up the setting time. Once the mixtures is firm you can spread it on the dough.
This recipe only will fill the roll, there won’t be enough to cover the roll with. The recipe says you should sift icing sugar over the roll. However, if you make a bit more, you will be able to decorate it. Just experiment with the amount. What is really important: the whipping cream mixture must be stiff, otherwise it will run out of the biscuit roll and you won’t be able to roll it up nicely.
