Line a 12 hole muffin tin with muffin cases.
Break the chocolate into chunks and place in a large microwave safe bowl.
Add the butter and honey to the bowl, then pop it into the microwave and heat in short bursts of around 30 seconds, stirring in between, until the chocolate has melted. Be careful not to overheat.
Stir well to completely combine the ingredients, then add the rice crispy cereal to the bowl.
Carefully mix together until the cereal is completely coated in the chocolate mixture.
Spoon the mixture into the muffin tin, dividing equally between the 12 cases.
Working quickly, decorate each crispy cake with 2 pretzels, 2 edible candy eyeballs and a red smartie, to make reindeer antlers, eyes and nose.
Once decorated, pop the crispy cakes in the fridge to chill for an hour or so until set.
