Put the butter and marshmallows in a saucepan. Place over a low heat and stir until melted.

Add the food colouring, one drop at a time. Stir and keep adding the colouring until you get a rich orange colour.

Add the rice krispies to the mixing bowl and pour over the orange mixture. Stir to fully coat the krispies.

Gather a heaped scoopful of the mixture and use your hands to compress the mixture into a ball. Lightly oil your hands to prevent sticking if required.

Break each twiglet in half and push a piece into the middle for a stalk.

At this point, the mixture will start to break apart so compress again and slightly flatten into a pumpkin shape.

Place on a tray lined with baking parchment to prevent sticking.

Repeat the process to make 12 pumpkin rice krispie treats in total.
