Place the first 6 ingredients into a food processor and process into a dough.
Spread the dough onto a non-stick backing or dehydrator sheet. Approximately the thickness of your thumb.
Shape it into a square, try to create fairly neat, straight edges, then cut into bite small squares.
I managed to get 12 slices.
Transfer to the freezer while you make the chocolate sauce.
Blend all above ingredients into a smooth sauce.
It's more than you need to cover the beetroot slices, but that's fine.
You'll just have some sauce for use in breakfasts, other cakes or to make hot chocolate (just add hot plant milk)
So now transfer to a small bowl.
Remove the slices from the freezer and dip them one by one in the chocolate sauce.
The sauce should set fairly quickly on the slices.
Place them back on the non-stick sheet and back into the freezer.
Once they are nice and cold again, you can take them out and either dip them again for a double layer,
or do what I did, which is to drizzle the sauce over the slices to create a pattern.
