Grease and line the holes of a 12 hole muffin tin with baking paper.

Chop the Mars bars into smaller pieces, then add them to saucepan along with the butter and the golden syrup.

Place the pan over a low heat and stir until it has all melted together.

Place the rice krispies into a large mixing bowl, then pour the melted chocolate mixture over. Mix well until the rice krispies are completely coated.

Spoon the mixture into the lined muffin tin holes and press it down firmly.

Set it into the fridge for an hour to set.

Once set, turn them out so you have xmas pudding shapes.

Melt the white chocolate in a heat proof bowl over a pan of simmering water.

Once fully melted spoon it over the top of the Xmas Krispie cakes, then decorate with Christmas sprinkles.

Place them in to the fridge for an hour or so until the chocolate has set.
