If you like clarting about this is for you!
Why not make your own edible set of dominoes.
I've now created a refined version of this design, which you might also like to check out:
Domino Cookie Cutter 2
Thing Files Include:
Number stamps 0-9. If you only want to make the standard 28 piece set you may choose to only print stamps 0-6.
4x & 5x Domino cutter. It's optional which you choose to print. When not in use the 4x version can hold the 7 stamps needed for the 28 piece set. The 5x version can hold all 10 stamps needed for the 55 piece set
*Diagram of dominoes in each set. It's probably worth pointing this out although if you create the dominoes in a logical sequence it is pretty easy to work out what you need.
The cutter is intended for use with dough 5mm thick. If you don't already own a tool for controlling dough thickness I would highly recommend downloading this customizable

1) If the dough is sticking to the cutter, use the "0" stamp to poke the dominoes out.
2) I would recommend making the dominos on baking paper, this will make it easier to move the uncooked dominos without deforming them in the process. Once the dominos have been cut, use a craft knife to cut around each individual domino, so it is on its own piece of baking paper.

For the number stamps I used a brim to increase contact with build plate, although it's probably unnecessary unless you're using a material with poor adhesion.
