  • 1 1/2 tsp ground cinnamon
  • 1 tsp allspice
  • 1/2 tsp ground cloves

  • pinch ground white pepper
  • 1 tbsp Opies stem ginger syrup (optional)
  • 2 tsp bicarbonate of soda
  • 115 g | 1 stick unsalted butter at room temperature
  • 1 egg lightly beaten
  • 440 g | 15.5oz | 3 1/2 cups plain flour plus more for dusting and rolling

For the Royal Icing

  • 3 egg whites 90g | 3.1oz
  • 500 g | 5 cups icing powdered sugar , shifted (more, or less as needed)
  • 1/2 tsp cream of tartar
  • 1 tsp vanilla extract optional

White chocolate frosting

  • 450 g | 1lb full-fat mascarpone cheese
  • 200 g | 2 cups icing sugar
  • 175 g | 1 cup white chocolate chips
  • 2-3 tbsp Opies stem ginger syrup

To assemble

  • 4 tbsp Opies stem ginger , very finely diced
  • Mini gingerbread cookies
  • Meringue kisses
  • Sprinkles
  • Macarons
  • Mini candy canes


Make the gingerbread cookie layers

  • Preheat the oven to 170C (340F) and line 3 heavy trays with baking paper (you will need to bake the cookies in batches).
  • Put the sugar, treacle and all the spices in a medium saucepan and heat gently, stirring constantly, until it reaches boiling point. Stir in a tablespoon of stem ginger syrup and take off the heat.
  • Stir in the bicarbonate of soda – the mix will start to foam up (my kids love this bit).
  • Add the butter and stir until completely melted.
  • Mix in the beaten egg and transfer to a large bowl.
  • Gradually add all the flour, stirring it in, until the dough is fairly firm.
  • Tip the dough onto a lightly floured worktop and gently knead into a ball. If the dough is too soft, sprinkle with a little flour. It should be pliable but not sticky. Slice in half keeping the dough you aren’t using covered with plastic wrap.
  • Roll the dough out to about 6mm ( about 1/4 inch) and cut out a 18cm (7in) circle using a cake board or plate. Cut out a smaller circle in the centre using a pastry cutter or smaller plate.
  • Transfer the cookie to a tray lined with baking paper and bake for 12-15 minutes, until the edges just start to colour
  • Remove from the oven and leave to cool completely until firm.
  • Create two more layers and cut some smaller cookies using festive cutters. They will need 7-10 minutes baking, depending on their size. Decorate these with royal icing, if you like.

Make the frosting

  • Put the chocolate in a bowl and microwave for 40 second bursts, stirring in between until melted and completely smooth.
  • Put the mascarpone and icing sugar in a large bowl. Add 2 tablespoons of stem ginger syrup and whisk using a hand mixer on the lowest setting to combine.
  • Add the melted white chocolate and mix on low speed to combine then increase speed to maximum until the frosting holds peaks. Transfer to a piping bagged fitted with a plain round tip or an open star tip.

Assemble the gingerbread cookie wreath

  • Pipe a layer of the frosting over the bottom cookie layer and scatter with chopped stem ginger.
  • Repeat with the second layer and top with the third. Add frosting over the top layer as well.
  • Add the decorations just before serving: mini gingerbread cookies, meringue kisses, sprinkles and whatever else takes your fancy!



This gingerbread letter cookie cake will keep for a couple of days in the fridge. Cut using a serrated knife with a gentle sawing motion. Remember to decorate just before serving or the decorations might soften due to the moisture in the frosting.
