Preheat the oven to 190C/ 375F. Grease a baking tin with butter.
Put the flour, baking powder, baking soda, salt, sun flower seeds in a bowl. Make a well and mix in the honey and the beer, combine everything together. Possibly the mixture is quiet thick, add up to 10 cl of water to make a nice batter.
Pour the mixture in the baking tin and bake in the middle of the oven for 45 minutes. Let it cool down on a rack.
