Bring all the ingredients (except the chocolate) over high heat, stirring constantly until the volume reduces to ¼ of the initial volume. You will be making condensed almond milk this way.
Turn off the heat and let it cool down a bit.
Add the chocolate.
Beat vigorously with a whisk or in a mixer until well homogenized.
Place in the fridge for a few minutes until firm (ganache point).
Form balls and pass in the sprinkles or chopped chocolate or crushed chestnuts.
