Randy - that's a confusing name for a product. I'd need to read the small print on the box before deciding what it was.
Both brands of baking parchment I have at the moment say the paper is treated with silicones to make it non-stick. If that isn't stated on the ASDA product, then I'd use it as greaseproof paper, which means it needs greasing on both sides before use, and removing from the cake while the cake is still warm - before the grease has time to set again.
tT - well done! If your cakes looked OK as they came out of the oven, then I'm sure they will be OK to eat! There's not much to go wrong, that wouldn't be showing up already.
