Chocolate carrot brownies

Ended up with an accidental surplus of carrots, could not find a recipe I liked the look of where I actually had all the ingredients, so kind of squished together a recipe with what I had in the cupboard. Quite liked it, so:
400g carrots.
200g castor sugar
3 eggs
150g ground almonds
100g very dark chocolate
200g butter
2 tablespoons cocoa powder
teaspoon vanilla essence (never know why this is added really, I assume it's some kind of Baking Spell, since I'm really not sure I can distinguish vanilla under all that cocoa and chocolate)

Pre-heat oven to 160 C (fan)

Roughly chop the carrots and boil (in water obvs) till soft.

Drain water, put the carrots into a liquidiser, make them into a puree.

Put the chocolate & butter in a bowl floating in a saucepan of hot water and melt.

Add the melted stuff to the liquidised carrots, give it a whiz till blended.

Add the eggs & ground almonds, whiz. If too stiff, add a tablespoonful water.

Add cocoa powder & sugar, whiz till blended.

Stick in 20 x 20cm brownie tin lined with either baking paper or that silicone stuff, put that in oven for 30-40 mins.

Eat when cool, they are a bit squishier when still warm.
