AI would cover the cake first with brown fondant then either crushed graham or brown sugar, making sure the color of fondant and cg/bs is similar. I would use light corn syrup thinned out with water to make it stick. Or if you have airbrush, you can airbrush the brown color after. Any pointed tool or even toothpick can make that heart.
Thank you :) I hadn't thought of corn syrup! Okay so would you indent before applying the sugar or after?
I would probably use the graham crackers...that way you don't have to deal with humidity being an issue. For this type application a 2:1 ratio of water to corn syrup works well......piping gel also works well as an adhesive....warm it a bit in the microwave to make it more fluid first.
Got it :) Thanks!
Im new so unsure about posting links but the cake blog has a sand "recipe" using cake scraps
thats a great idea! Thanks :)
