The frozen yogurt cake is an easy to make dessert with a crunchy biscuit base and soft yogurt cream that does not require baking. You can also prepare it without isinglass and accompany it with fresh seasonal fruit.

Grease a 20 cm diameter cake pan and pour the mixture. Press the mixture with the back of a spoon to create the base of your frozen yogurt cake.
Now, take care of the cold cream.
Soften the isinglass in a small bowl with cold water. Let it melt in a small saucepan with two tablespoons of yogurt and a tablespoon of milk. Turn off the heat as soon as it has melted and let it cool. Meanwhile, whip the cream and sugar it with two tablespoons of confectioner’s sugar. Add the yogurt and the warmed isinglass. Blend everything with a kitchen whisk, very slowly and with movements from bottom to top. Once ready, transfer the mixture into the cake pan and level it well with the help of a spoon.
