Preheat the oven to 200°F.
Place the wheels pretzels on a baking sheet. Place one hug on top of each pretzel.
Bake in the preheated oven for 5-10 minutes, or until the chocolate is shiny and soft.
Remove from the oven and quickly place 1 m&m in the centre of each hug. Press down evenly. Repeat with the remaining pretzels.
Add a dot of black food gel to the centre of each m&m. Allow to cool at room temperature.
Once cooled, place in an airtight container and store in the fridge.
