Remember to screenshot the ingredients list at the bottom of the page before you go shopping.

  1. Bake the cake

    Preheat the oven to gas 3, 170°C, fan 150°C. Grease a 20cm round, deep cake tin with butter, then line with nonstick baking paper.

    In a bowl, beat together 140g salted butter, 140g light muscovado sugar, 225g self-raising our and 2 large eggs until pale and creamy. Fold in a 411g jar mincemeat and 200g halved glacé cherries with a metal spoon. Pour into the tin, level, then bake for 1¾ hrs until well risen and a skewer inserted into the centre of the cake comes out clean.

    Brush the warm cake with 2 tbsp amaretto, if you like, and cool in the tin on a wire rack. Remove from the tin when cool and peel off the baking paper. The cake will keep for 1 week in an airtight container.

  2. Prepare the chocolate igloo

    Melt 150g white cooking chocolate in a bowl in the microwave in short bursts until just melted. Stir until smooth, then set aside to cool and thicken for at least 15 mins. Inflate the balloon to about 17cm in diameter and tie it up.

    Cover a plate with nonstick baking paper. Dip the top of the balloon in the cooled chocolate. Use a spoon to coat the balloon about halfway, spreading evenly on all sides.

  3. Make the polar bear

    Make the polar bear. On a sheet of nonstick baking paper, using 50g ready-to-roll white fondant icing take  a piece and roll into an oval shape, about 4 x 3cm, for a body. Roll out a smaller 2cm ball for a head. Make a flattened circle for the mouth area, 4 sausage- shaped legs, and 3 small balls for the ears and tail. Use a toothpick to indent a mouth and paws. Using 5g ready-to-roll black fondant icing, roll 2 small balls of black icing for eyes and a larger flattened circle for a nose.

  4. Check on the igloo

    Check the chocolate balloon for areas that are very thin in chocolate. Gently reheat the leftover white chocolate, cool for 15 mins, then use a pastry brush to smooth over any patches. Chill for 30 mins. Set aside the leftover melted chocolate.

  5. Prepare the cake

    Meanwhile, put the cake upside down on a cake stand or board and press down lightly to secure. Taking 300g tub of ready-to-use vanilla flavour frosting, spread a very thin crumb coat layer of frosting over the cake. Chill for 30 mins, then smooth over the remaining frosting.

  6. Decorate the cake

    Arrange the polar bear lying down in the centre of the cake and scatter with 40g mini white marshmallows (reserving 12) and 25g white chocolate stars.

Take the 2 white chocolate writing icing tubes and pipe bricks around the dome, leaving a space to make a door. Reheat the leftover white chocolate and use to fix the reserved marshmallows into a door shape. Chill in the fridge for at least 12 hrs or until set hard.

  7. Smash the igloo

    Dust with icing sugar just before smashing the dome open to reveal the polar bear. The smashed cake will keep for 5 days in an airtight container at room temperature.
