I used tiled clones with some randomness in hue and saturation, and fully random rotations. I used the QR code renderer and deleted the clones that were on "blanks." The renderer has a function to use other glyphs, but it won't do the rotations or color variations.
I had a lot of trouble trying to get the QR code to work well with phones until I made the "target" fiducials nice and smooth clear shapes. I had originally tried to make them out of the sprinkles as well, but it was just too inconsistent for the phone to see.
For the rest of the scattered sprinkles, I used tiled clones over a gradient and then used the tweak tool to "brush" them away from the text areas.
