1 packet Exquisita Vanilla Cake Sponge
220 cc milk
200 grams impalpable sugar
1 spoon lemon juice
Butter (for the baking sheet)
Flour (for the baking sheet)
Heat the oven at 160° for 15 minutes.
Butter and flour a savarin mould of 15 cm diameter approx. In a bowl, beat the eggs with the milk and add the contents of the Exquisita Vanilla Sponge packet. Blend well and beat for 3 minutes with an electrical beater or for 5 minutes manually. Pour the preparation into the mould and cover half of it.
Bake for 60 minutes or until a skewer comes out clean and dry. Set aside to cool for 15 minutes and remove.
Cut through the middle and set aside.
Tip the impalpable sugar, the lemon juice and the water into a bowl. Beat with a whisk in order to prevent it from curdle, until you get a uniform and white pastry.
Divide the pastry into 7 equal parts and dye each one with different colouring using the colours of the rainbow. Use different small pastry bags for each colour and draw a rainbow on top of the sponge.
Spread dulce de leche* on the corners and stick the marshmallows so they represent the clouds. Serve.
(*) dulce de leche: Argentinean caramel jam
