Decorated dessert biscuit
- 40cm X 30cm Silicone Baking Sheet
Deco dough :
- 80 g butter
- 80 g icing sugar
- 80 g egg white
- 60 g cake flour
- 30 g unsweetened cocoa powder
- 75 g ground almonds
- 75 g icing sugar
- 20 g cake flour
- 2 eggs
- 2 egg whites
- 20 g caster sugar
- For the decor dough, start by softening the butter. For this you can gradually heat it in the microwave at low power.
- Add the icing sugar and mix the whole with a whisk.
- Sift the flour and unsweetened cocoa powder over it. Add the egg whites and mix everything.
- We will use a 40 cm by 30 cm silicone baking sheet. Spread a quite thin layer of decor dough over the entire surface using a palette knife.
- Using a notched triangle, draw parallel lines in the decor dough. Then place this silicone sheet on a baking sheet, then put everything in the freezer.
- The remaining decor dough can be frozen for later use.
- For the Joconde cookie, put the almond powder in a container, add the icing sugar and the flour. Break an egg then mix everything with a whisk.
- Break the second egg, then whisk vigorously for 2 to 3 minutes. It will lighten and whithen.
- Pour the egg whites into the bowl of the electric mixer with a bit of caster sugar, then start whisking.
- When the egg whites form a firm peak, add the remaining caster sugar gradually.
- Once the egg whites are firm, add them to the almond mixture and mix gently using a whisk or a spatula.
- Take the baking sheet out of the freezer, then spread this Joconde cookie over the decor dough still frozen. Use a palette knife if possible and be regular.
- Bake the decor cookie in an oven preheated to 210 ° C for about 10 minutes while monitoring the baking regularly.
- Remove it from the oven and slide the decor cookie onto a wire rack to allow it to cool.
- Finally, turn the decor cookie over onto a sheet of greaseproof paper, then gently remove the silicone sheet.
