Mix the muesli with the honey.
The honey here is your glue, so make sure the mixture has nearly come together. I often pick a little up, and I know it will stick if I can mash it into a ball.
Now grab your ice block moulds and push the muesli into the base. REALLLLY push it into the base; you want these compacted. That way, none falls off.
Top with your yoghurt and finish off by popping your popsicle in and having them set in the freezer.
Mine takes a couple of hours to set.
