The astronaut’s biscuit

6 March 2016


Biscuits that will accompany your intergalactic journeys

The astronaut biscuit, despite its name recalling the space does not contain any suspicious ingrédients! It contains maple syrup and white chocolate for a pastry combination that is at the same time soft and crunchy.

This lovely title was given by one of my colleagues, who considered this biscuit being nourishing enough to make an astronaute survive during an outer space journey. In fact the astronauts biscuit consists (except for the ingredients mentioned above) essentially of butter and sugar. But since at Cosmic Tomatoes we are of very positive nature will avoid the word fat and prefer telling you that today we have a Biscuit that is “rich”.



We would like to offer our biscuit to NASA, Roscosmos to or any other space agency interested. Yes, we have the right to dream.

While waiting for this partnership, we prepare a stock of astronaut biscuits. And now the recipe!


– 225g Flour
– 325g Salted butter
– 75g Sugar
– 380g Condensed milk
– 100g Maple Syrup
– 200g White Chocolate


Prepare your mold: Cover it with a baking sheet, and spread some oil on the surface.



Mix the flour, 175g of the butter and sugar in a bowl.



Roll out the dough on the bottom of your pan.



Put the pan in a preheated oven at 150 ° C for half an hour. Then let the dough cool.



While you wait the baking of the bottom layer, mix the remaining butter, maple syrup and condensed milk in a saucepan over low heat.

Stir the mixture constantly with a wooden spoon to prevent it from sticking to the bottom of the pan. Continue cooking until obtaining a slightly thick cream (10min approx).



Allow the -maple syrup mixture to cool slightly before pouring it on the biscuit. Let to harden.



Melt the white chocolate in a double boiler.

Pour the white chocolate over the two previous layers.



If, like us, you want to create a texture on the white chocolate, or add a few drops of food coloring, do it before the chocolate begins to harden.
