Bake the sponge cake in advance, cool it, and cut it into three equal cakes.
Cut 2-3 washed strawberries into small cubes.
Mix the whipped cream with the sugar and beat with an electric mixer.
Spread a little cream on a flat cake plate and place a sponge cake on top. Spread with whipped cream and sprinkle with sliced strawberries. Repeat the layers.
Put 2-3 tablespoons of whipped cream in a piping bag fitted with a nozzle, and spread the rest of the whipped cream over the cake and smooth it with a pastry spatula.
Spread a line of frosting across the surface of the cake, dividing the cake into two parts. The top part is the snowman's hat, and the bottom part is his face.
Cut the remaining strawberries in half and place them on top of the cake to form the snowman's hat. Make the snowman's eyes from blueberries and his nose from a small piece of strawberry.
Sprinkle the finished cake with coconut flakes.
