Banana one thousand layers
Ingredients:12-15 servings
For the dough,

•     2 eggs
•     8 egg yolks
•     50 grams soft unsalted butter (if using salted, not add more salt)
•     2 cups sifted flour
•     1/3 teaspoon baking powder
•     Pinch of salt
•     3-5 tablespoon of orange juice

for the filling,

•     500 grams of dulce de leche
•     2 cups whipping or heavy cream
•     2 tablespoons sugar
•     banana or vanilla extract

Directions:

1.     Two days before serving the cake make the dought and bake it. Preheat oven to 180C or 350F. Sift flour with baking powder and salt.
2.     If using a stand mixer, use the paddle attachment, add butter and beat until incorporated into the flour, add 1 egg, beat until incorporated, add another egg and repeat, do the same for each egg yolk, let mixed for 2 minutos to form a dough,  if after adding all the ingredients is still very dry, keep adding the orange juice one tablespoon at the time, keep mixing until a soft and very elastic dough form, knead about 5 minutes more.
3.     If doing by hand: make a volcano with the flour and add to center the butter, eggs and yolks and incorporate, at first I usually work with 2 forks and when everything is more mixed start to knead with my hands, work the dough until smooth and elastic.
4.     Form a ball with the dough wrapped it in  plastic film and let stand at least 1/2 hour in the refrigerator.
5.     Divide dough into 12 equal pieces, generously flour the counter and roll the dough until very thin, cut using a plate about 23 cm (9') in diameter. Repeat with the other pieces. 
6.     Bake on baking sheet for 5-7 minutes until just begin to brown, remove and cool on wire rack.
7.     The next day make the whipped cream: beat the cream until it forms soft waves, add the sugar, beating until sugar dissolves and stiff peaksform. Add the banana extract (I use 2 teaspoons) and stir to incorporate, test and adjust the flavor and sweetness to taste.
8.     The dulce de leche needs to be at room temperature and be lightweight, not like jelly, but as a mayonnaise, add milk or cream to thin it, stirring until incorporated. I add 4 tablespoons of milk.
9.     Fill the first layer with dulce de leche, continue with alternating thin layers with whipped cream, gently pressing each layer to be form a compacted cake.
10.     Top with whipped cream, then I mixed the dulce de leche with the remaining whipped cream to decorate with a star-shaped tip.
11.     I use a transfer cake to decorate the cake up, are easy to use, but should be placed on the day you will serve the cake, I did it the day before and cracked a little.
12.     Leave the cake in the refrigerator overnight, serve.
