Have all the ingredients at room temperature.
Start by making the dough.
Whisk the butter with the sugar until fluffy.
Incorporate two of the eggs in the mix.
Combine the flour with the baking powder.
Add the flour all at once and knead into a dough.
Cover with cling film and leave in the fridge for half an hour.
Add the milk and the vanilla essence in a pan and heat.
Whisk the eggs with the sugar until fluffy.
Mix the flour with the cornstarch and add to the eggs.
When the milk is almost boiling, add the eggs and flour mixture and whisk fast, not allowing the eggs to cook.
You should obtain a thick cream.
Set aside and let it cool completely.
Prepare a round cake tin, lining it with baking paper.
Preheat the oven to 180 degrees Celsius.
Divide the dough into two equal pieces
Roll the first one and place at the bottom of the pan,covering the sides as well.
Set aside a small piece of the other dough.
Place the cold custard cream over the dough in the baking tin.
Top with cherry jam – as much or as little as you like.
Roll the other piece of dough and cover the top part of the cake.
Form a cross with the extra dough you set aside and place it on top of the cake.
Beat the last egg and brush the top of the cake with it.
Bake in the oven at 180 degrees for 30-40 minutes, until golden brown on top.
Let it cool completely before taking it out of the baking tray.
Cut the cake in slices and serve it for dessert.
