Chocolate Petit Gateau

A delicious stack of rich chocolate mousse, fruity mango, and crunchy cookie, create an unbelievable dessert.

Chef Praveen Dhananjayan of The Grand America shared his recipe and his technique with a class of 80 participants at the Gygi Chocolate Extravaganza. He is a master of pastry and his passion for pastry shows in his desserts.

Making this petit gateau is a serious undertaking for a beginner. But, try making one component at a time. Figure out the Paillete feulletine and add it to some ice cream. Next, make the mango mousse. Slowly tackle each of the components until you’re ready to make the whole dessert!
