"Great - no problems!"
Bought these without looking at reviews, then nearly regretted it earlier today as I thought to look for tips on using them, as I have done before with other things. I used Cake Release, and pushed the dough fully down before putting more in to fill in, to make sure the mould features would be filled. They have come out perfect! I just had to loosen them slightly with a sharp knife once they had completely cooled. My next batch is now in the oven - very pleased!
