Heat the oven to 160°C/325°F (fan assisted)
Grease an 8 inch baking/brownie tray with a little butter.
Gently melt the butter and choc together in a large pyrex bowl over a pan of simmering water. Remove from the heat when nearly melted and add the sweetener stirring well.
Add the cocoa, coconut flour, chia seeds and salt and mix well.
In a separate bowl, whisk the eggs and vanilla extract together until frothy and light.
Gradually add the egg mixture to the chocolate mix and fold until blended.
Ensure mix is fully combined.
Pour into the baking tray.
Bake on the middle oven shelf for 20-30 minutes (CHECK AFTER 20 MINS). Don't be alarmed if it looks a bit 'bumpy' at this stage, it will settle.
Leave to cool in the tray before carefully turning out on to a cooling rack.
Cut into delightful bite-size pieces or just eat it whole. On special occasions, I might have one with double cream and fresh raspberries.
Share if you have no other option. Kelley will usually double the recipe and freeze half which works well and stops me from eating them all in a scarily short space of time.
