I used to use either water or “Tylo glue” (Tylose mixed with water to form a glue). The problem is, you have to be extremely careful with water alone because if you use too much and it drips or runs down your cake, it makes a mess in a hurry!
The Tylose glue really does work great – but it’s not ready in an instant. It’s best to mix up and let it sit (and sort of “congeal”) overnight in the frig. This is not always practical for us decorators who
are super scatter-brained don’t always think that far ahead.
But recently, I’ve started doing a couple of new things that I like much better!
When I can get away with it (when the decorations are flat), I rub the entire surface of my cake with shortening and apply fondant on fondant. A good example of that is the Rainbow Chevron Cake up top! All of those stripes are adhered to the cake with shortening alone and it works great! I also use shortening almost all of the time now to put letters one. I can move them around without damaging anything if I discover that I’ve put a name on off-center or too high or low!
How to Make Fondant Sugar Glue
However, today I'm sharing my newest and most favorite method… melted marshmallow fondant with a little water! I learned this trick from CorrieCakes on Facebook and it’s a perfect, easy “glue” for all fondant decorations.
It only takes seconds to make and if you decorate with mmf, you have everything you need on hand to make this “glue”. It’s thicker than water, doesn’t “run” easily and well… it’s just a great solution!
See the picture up there… you just take a small ball of fondant, put it in a microwavable glass dish with a little water (less than a teaspoon) and microwave for 15-20 seconds. You’ll get a perfect, sticky sweet glue!!
If it's too thick, add a tiny bit more water, microwave for a few more seconds, stir and it's fixed! If it's too watery, you can microwave it more to thicken it up (just be careful... small glass bowls get really, REALLY hot!).
