How to create a gummy candy cake? I want to give my gf a present for Valentine's day that consists on a board with glued gummy candy, marshmallows... all that lovely sweet stuff. When put all together it will be like a romantic painting but with glued gummy candy instead.

However, I don't know what to use as a frame to stick the candy and also what to glue them with!

Is there anyway to make/(buy) some kind of edible frame? I'm ok with plastic or glass but if it could be edible it would turn out awesome! :)  Furthermore, do you have any ideas on what to glue the candy?

Final Result:



This is what I ended up doing. The base is a sponge flan cake, which I bought in the supermarket. Regarding the glue, I was presented with the options of a pure glucose syrup and a shinning glucose gel. I chose the latter, since I was told it was commonly used to stick crystallised fruits in cakes and that sort of stuff :)

Thank you all for the tips and the inspiration. She loved it ;)
For the frame, I would suggest baking a cake, brownies, gingerbread or even cookie dough in a baking sheet (so it's one big, quite thin piece). But put the temperature of the oven lower than if you would use a regular baking mold. You could also use a piece of styrofoam/polystyrene*, covered with tin foil. Then you can use tooth picks to hold everything in place. To cover the tin foil, use sour strips, marshmallows...

As glue you can use chocolate or caramel if it should sit quite steady. You can also use edible glue (this is often used to glue pieces of fondant to cupcakes). If you present it horizontally, you can use a lot (syrup, honey, jello, icing, even a thick pudding...). I think you could even melt some candy and use it as glue. I have no idea however how strong this would be.

*) I'm not sure this is the correct English term. To be clear, I mean this.
