80 Butterfly and Lavender Greaseproof Cupcake Cases 1 "Beautiful, But!!" Mrs Glover 13 August 2019 Brought these cupcake cases for my niece's vintage theme wedding. Beautiful design perfect for her theme. But they are NOT Greaseproof, as soon as the cakes came out of the oven they were leaking. Left to stand, you could see the grease on the cases. Has I was making 150 cupcakes, I froze them to decorate the day before the wedding. Again as soon as they were thawed they leaked. And I used best quality ingredients to make the cupcakes. Thankfully I had brought some cupcake collars so hid the cases. So lakeland please report back to the manufacturer as they are definitely NOT Greaseproof!!! A note from the team We were sorry to learn of your experience and we've certainly made a note of your findings. We're not really sure why this has happened, you could try a different recipe, baking the cupcakes for a couple of minutes longer and removing them from the tin straight away after baking.
