Preheat the oven to 180 °C. Boil the carrots in hot water until soft for approx. 15-20 minutes. Combine soft butter, sugar, vanilla and eggs.
Blend the carrots to a smooth purée. Add the carrot-purée as well as the other ingredients to the bowl and mix until the batter is smooth. Pour it into a muffin tray.
Bake the muffins for approx. 20 minutes. Let them cool.
For the frosting:
Add 2 tbsp butter, spices, cream and brown sugar to a pan and bring to the boil. Put it in a bowl and let it cool down in the freezer for approx. 15-20 minutes.
Add the remaining butter and icing sugar to the cold mixture and whisk until creamy. Pour it into a piping bag and cool it, until it's firm enough to be piped on cupcakes.
Use a piping bag to decorate the cupcakes. Sprinkle with cinnamon and serve.
