Line the recesses of a muffin tray (12 recesses) with 1 paper baking tin each. Mix flour with baking powder, salt and sugar. Whisk eggs, oil, yoghurt, lemon zest and milk in a bowl.
Briefly stir in the flour mixture with the whisks of the mixer. Fold in frozen raspberries.
Spread the dough on the baking cups. Bake in the preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for approx. 25 minutes. Remove and let cool on a cake rack.
Dye marzipan brown with cocoa. Divide into 24 equally sized pieces and shape into sheep's ears. Decorate chocolate eggs with 2 ears each. Squirt eyes onto the sheep's heads with white and brown sugar writing.
Allow to dry.
Mix butter and icing sugar with the whisk of the mixer until creamy white. Stir in the cream cheese briefly. Spread 2 tablespoons of cream cheese cream in a large ice-cream scoop (7.5 cm Ø) and place it on each muffin as a hemisphere.
Smooth the edges. Decorate with 1 sheep's head and marshmallows.
