Sorry, I have no idea. I didn't realize it was MP cupcakes you were inquiring about. It didn't so which topic it was in on my phone.I'm doing melt and pour and am having a hard time getting a melt and pour icing done. I've never done it before but it's pipping fine it just doesn't set hard. It's more like springy. Maybe that's the hardest it gets just wasn't sure.
I wasn't going to do like frosting on a real cupcake but the royal icing that's used to do a bath bomb cupcakes and it sets rock hard. Didn't know if it's possible for melt and pour to set that hard
