Ingredients

  • 50 grams Unsalted butter
  • 30 grams Powdered sugar (or another type of sugar)
  • 1/4 Eggs (large)
  • 110 grams Cake flour
  • 1 leftover from the tart Egg
  • 10 grams Sugar
  • 4 grams Cocoa powder
  • 4 grams Cake flour
  • 200 ml Milk
  • 4 tbsp Sugar
  • 1 Egg yolk
  • 2 tbsp Cornstarch
  • 1 Vanilla extract
  • 100 ml Heavy cream
  • 1 tbsp Sugar
  • 2 Banana
  • 1 Melted chocolate (for topping)
  • 1 Almonds (for toppings)

Method

  • Make the tart crust using the ingredients!
  • Add butter to a bowl, stir to a cream like state, add in the sugar and eggs, and stir.
  • Add in the sifted cake flour to that, fold it onto itself with a rubber spatula, gather into one lump, and let chill in the fridge for over an hour.
  • Make the custard cream with the ingredients!
  • Add milk to a pot, and warm it up to the point just before boiling.
  • Place the egg whites and sugar into a bowl and mix until it turns white.
  • Add corn starch to that, and stir well.
  • Add in half of the warmed milk to that and stir.
  • Pour the batter from Step 2 into the remaining milk in the pot, and mix well with a wooden spatula over a medium heat.
  • Remove it from the heat once it starts gently boiling, place into a flat dish, cover the batter with plastic wrap, and chill in the fridge.
  • After the custard cream has cooled, add heavy cream and sugar to the bowl, and whip to make whipped cream.
  • Mix it together with the custard and let cool.
  • Place the tart dough on top of a surface sprinkled with flour, and spread it out a little larger than the tart mold.
  • Press it into the mold, cover the dough with aluminum foil, place a weight inside, and bake at 180C for about 25 minutes.
  • While the tart is baking, let's make the cocoa sponge filling that goes inside with the ingredients!
  • Place eggs and sugar into a bowl, and thoroughly mix until it turns white.
  • Add in the sifted cocoa and cake flour to that, and stir without popping the bubbles.
  • Pour the batter from Step 6 into the mold and bake at 180C for 15 minutes.
  • After it has cooled, place it into a custard cream pastry bag and squeeze it into the tart.
  • Line up bananas that have been cut diagonally, decorate with melted chocolate and almonds, and it is done!!
  • (The photo shows the plain type).
  • Try packing the leftover cream into bread for cream bread.
  • This time in place of the chocolate decoration, I tried making it by mixing cocoa and heavy cream.
