Make a batter from the dough ingredients and pour into a greased wreath form. Bake in the preheated oven at 175 ° C on the lower rack for about 60 minutes. Let the cake cool down.
For the cream, whip all the ingredients into a light mass. Cut the cake horizontally twice. Brush each layer with cream, place on top of each other and cover with the cream on the outside.
Sprinkle with brittle and put the remaining cream in a piping bag. Sprinkle rosettes on the cake. Finally put the candied cherries on top.
