Place your chocolate in a heatproof bowl over a small pot of water 1/4 full. Cook over a medium heat until the chocolate has completely melted.
Add the protein crisps and stir until they are completely coated and an even chocolate-coloured consistency.
Use a silicone spatula to get all of the mixture out onto a piece of baking paper. Place another sheet on top.
Use a rolling pin to compact and even out the mixture between the sheets of baking paper. You can just eyeball the size, but I prefer to use my Lindt paper packaging to roll mine out into a rectangle 20cm long and 10cm wide. This way I get evenly sized pieces of protein crisp chocolate.
To do this, I fold in the edges of the baking paper to create a snug little 'packet' of chocolate the same size as the Lindt packaging. I then flip it over so the seams are against the counter and use my rolling pin firmly press the mixture out to all the edges. Think of making a butter packet for laminated pastry.
Score the protein crisp chocolate into 8-10 pieces using a blunt knife. Don't cut all the way through but score well enough that you will be able to snap the bar into even pieces once it is has chilled.
Place it in the fridge for at least 30 minutes to completely set. Snap into pieces and store in an airtight container in the fridge.
