Bring the oat cream to boil in a sauce pan and take off the cooker.
Add in the chocolate and stir until smooth and shiny consistency. The chocolate will melt in the hot oat cream.
Pour in a square container about 14cm x 14cm or something similar. The container should be lined with baking paper so that it will be easy to take the chocolate out when it's set. Let it sit in the fridge for about 2 hours until solid enough to make truffles. If you are in a hurry, put it in the freezer for shorter time.
When the chocolate is well set, remove from the container and cut into 20 square cubes or similar.
Roll each square between your palms. Roll the truffles in the coating (I used cocoa power, desiccated coconut and chopped nuts) Keep them in the fridge in an air-tight container.
