Soak raisins in lukewarm water overnight.

Rinse soaked raisins, put them in a blender and blend.

Put in a bowl, add all of the other ingredients and mix until you get a firm mixture. If it's too sticky add some more oat flour and if it's too dry just add some water.

Roll it out between two layers of baking paper.

Cut into around 8 bars.

Melt the chocolate and drizzle it over the bars.
