Flourless chocolate brownies - gluten free and no sugar

Tonight was my first attempt at a flourless chocolate brownie. Was delicious and I tweaked it from a recipe I got from allrecipes.co.uk for a flourless chocolate cake.

Ingredients:

100g 85% Lindt dark chocolate
150g organic unsalted butter
80g Greens and Black Organic Cocoa
2 x vanilla pods
3 x eggs
150g Xylitol (this is a sugar alcohol that I used to replace sugar)
100g strawberries

Directions:

1. Preheat the oven to 150 degrees C (gas mark 2). Grease an 20cm round cake tin, and dust with cocoa powder.
2. Separate the eggs and set aside the yolks for later
3. Whisk the egg whites until they are soft peaks
4. In a bowl over lightly simmering water, melt chocolate and butter
5. Scrap vanilla beans out of pods
6. Once melted remove chocolate and butter from the heat and let cool for about a minute
7. Stir in egg yolks, xylitol, cocoa and vanilla
8. Gently fold in a heaped tablespoon of the beaten egg whites into the mix
9. Put mix into bowl of remaining egg whites and fold gently until egg whites can no longer be seen
10. Pour into the prepared cake tin.
11. Bake in preheated oven for 30 minutes. Let cool in pan for 10 minutes, then turn out onto a wire rack and cool completely
12. Serve with slices of strawberry, you could also serve with melted dark chocolate or raspberries
