First, put 300g of (vegan) yoghurt in a bowl with 25g of coconut flakes, 30g of oats and 35ml of agave syrup and mix all the ingredients together. Put the bowl for 5-10 minutes into the freezer.
Then place baking paper on a plate and put about 1 tbsp of your coconut mixture on it and shape it with your fingers (you can also use a mould) into a bar. I used two CLEANED geometric triangles (Geodreick) to achieve straight corners, but you can also use everything else to achieve straight corners - it just has to be clean
Once you have formed all the coconut mixture into about 6-7 bars, carefully place the plate in the freezer.
After about 2 hours (or as soon as the bars are almost frozen) melt 100g (vegan) dark chocolate over a water bath or in the microwave. Take the coconut bars out of the freezer. They should now be firmer and release from the baking paper without collapsing (if they are still quite 'soft', be sure to put them back in the freezer until they are firmer!)
Now cover the bars with the melted chocolate. I coated them over a grid and then melted the remains again so that no chocolate was "wasted".
Now place the bars in the fridge for at least half an hour so that the bars can defrost again inside. Enjoy : )
