This is "Durable Cake for 3D and Wedding Cakes" from the recipe section, MMF made with chocolate marshmallows from MNFlowerGirl. I also painted the initials with luster dust and vodka- I need to work on my penmenship! This is my second attempt at fondant on a square cake- not too bad, not too good either, but I'll keep trying. Let me know if anyone has any suggestions, please!
