Annabel Karmel's melting snowman cookies

Preheat the oven to 180°C/Fan 160°C/350°F/Gas mark 4

Measure the butter, plain flour, cornflour and caster sugar into a food processor. Whizz until combined. Tip out and knead lightly to form a soft dough. Chill in the fridge for 10 minutes

Roll out the dough and stamp out 16 circles, each about 8cm in diameter. Place on baking sheets and chill for a further 20 minutes. Then bake for about 15 minutes (they will spread a little). Leave to cool

To make the icing, whisk the royal icing and half of the water in a free-standing electric mixer until the icing is thick and shiny. Add the glycerine and whisk again. Add the rest of the water 1 tbsp at a time, until the mixture is the consistency of thick yoghurt

Put the cooled cookies on some non-stick paper. Spoon over the icing, so it drops off the edge of the cookies to look like melted snow. Place a marshmallow at the outer edge of each cookie

Push a Tic Tac into the marshmallow to make a nose, draw on 2 eyes with black writing icing and place a fizzy strawberry strip around the base of each marshmallow to make a scarf. Finally, use 3 Mini Smarties to make little coloured buttons
