Heat 300 g cream. Mint tablets, except for a few for decoration, melt in them while stirring and bring to the boil briefly. Cover and let cool well overnight
Separate eggs. Beat egg whites and 3 tbsp. cold water until stiff. Add sugar and salt. Stir in the egg yolks one by one. Mix flour, starch and baking powder, sieve and fold in
Spread the sponge mixture on a baking tray lined with baking paper (approx. 35 x 40 cm) and bake in a preheated oven (electric cooker: 200 °C / fan oven: 175 °C / gas: level 3) for 10-12 minutes. Turn onto a tea towel and remove the paper. Let it cool down
Whip mint cream and 200 g cream separately until stiff. Cut off one third of the sponge cake lengthwise. Halve both pieces crosswise to make 4 pieces. Spread a large piece of dough with half of the mint cream (put 2 tablespoons aside). Place the two smaller pieces on top. Spread the rest of the mint cream on the cake and cover with the remaining piece of dough
Mix half of the cream with 2 tablespoons of mint cream. Spread the surface of the cake with it like a wave. Pour the remaining cream into a piping bag with a large star-shaped spout and squirt two large tuffs onto the cake. Place the Easter bunnies on the tuffs. Decorate the cake with cocoa, mint bar and mint
