Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Grease a muffin tray with 12 troughs well and dust lightly with flour. Peel, wash and roughly grate the carrots. Drain pineapple and chop or chop very finely.
For the dough, mix eggs, sugar, 1⁄2 teaspoon cinnamon, oil and buttermilk with the whisks of the mixer. Mix flour, baking powder and almonds and stir into the egg mixture. Finally fold in carrots and pineapple.
Spread the dough into the muffin wells and bake in a hot oven for 15-17 minutes. Remove from the oven and allow to cool for about 30 minutes. Then carefully remove from the trays and allow to cool.
For the Frosting stir cream cheese and milk until smooth. Add icing sugar and whisk until thick and creamy. Spread the cream cheese loosely on the muffins with a spoon, except for about 2 tbsp.
Sprinkle each with approx. 1 tablespoon coconut shavings.
For the rabbit decoration, dip mini marshmallows in the remaining frosting and roll them in the remaining coconut flakes. Place 1 marshmallow on each muffin as a bunny tail. Cut large marshmallows diagonally, moisten the cutting surfaces with some water and press them into the pink sugar.
Set as rabbit ears on the muffins.
