Carrot cake or my happy autumn

The good thing about autumn is orange. This is why one of the straightforward ways to celebrate autumn (yes, it's followed by the winter but it's not a reason not to celebrate) is a carrot cake! Easy, tasty and odorous.

2 cups of flour + baking powder
~1 cup of sugar (depends on how sweet you want your cake to be. I put slightly less and everyone's happy)
4 eggs
100 g of walnuts (I broke them in pieces and fried a bit with some cinnamon)
1 cup of sunflower oil
350 g of ground carrots
cinnamon, ginger, a bit of salt, 
a spoon of cointreau or orange peel
(whatever you think fits with carrots)
250 g of mascarpone 
(well, any other cream cheese can do, too)
50 g of sugar powder 
(or even more, if you don't like your icing sour)
peel and juice of a lime

Start to heat the oven at 180 C. Mix the flour, baking powder, salt and spices. Mix eggs with sugar (better, with a mixer), add the oil to the mixture. Add the flour blend little by little, add carrots and nuts, mix again. Bake for 40 minutes (till the dry toothpick) at 180 C. Wait till it cools down. Mix mascarpone with sugar powder and peel and lime juice, distribute it over the cake and enjoy!
