For the brownie, first you have to melt the chocolate. Then add the diced butter until it melts with the chocolate and mix well to form a dough.
Then beat the eggs with the sugar until they are white-colored, and mix with the melted chocolate. Add the sifted flour and stir until obtaining a homogeneous dough. To bake, line a baking pan with foil paper and pour the mixture in it. Bake at 300°F for about 30 minutes. Remove from oven, allow to cool, and cut the brownie with a 2 cm diameter pasta cutter.
To assemble the Santa hats, first put the Chantilly cream in a pastry bag; first the brownie base, then a generous layer of Chantilly cream, a whole strawberry, and then make a meringue pompom. You will see that the shape looks just like Santa Claus’ hat.
