Put a spoonful of tinned apple or grated fresh apple in the middle of each square. I put some dark choc chips on the top. Fold over to make a triangle and use a fork to seal the edges. Sprinkle sugar on top.
Place in slow cooker on high with teatowel under the lid. Mine took 2 hours :)
I have also made raspberry jam and apple, raspberry jam, apple and white choc, banana and choc.
