Pre heat the oven, 180ºC.

Mix flour with sugar and baking powder and set aside.

In a blender, put the carrots, eggs and oil (I use soy oil). Beat until you see a smooth mixture

Put the carrots with the flour and mix gently. Then, put in a greased baking pan and put in the oven for about 30 min. You can use a toothpick to see if its done.

For the topping (it's called "brigadeiro"):

Mix all the ingredients in a pan and cook under low heat, always mixing with a spoon.

You'll see the mixture will start to boil and double its size, keep mixing with the spoon, pay attention to the sides so they don't get overcooked or your Brigadeiro will get crumbled (its ok if it happens, btw)

Keep like that till you see the mixture is a bit thick and no more attaching to the bottom of the pan.

Put over the cake and spread gently. Let cool a little bit and serve.
