Here is a step-by-step tutorial on how to make your own Lego minifigurine head cake pops. First, though, you will need to bake, let cool and crumble a cake. Then mix the cake crumbs with your favorite icing.
The consistency should be such that you can form a ball without it crumbling but not so moist that it it doesn’t hold its shape or falls off the lollipop stick when dipped.
It’s a bit of an exact science so you may want to do a dry run before continuing on to the next stage.
