Preheat the oven to 160° C fan (180° C conventional / 350°F / gas mark 4).
Grease two deep spring form cake tins (20cm diameter x 7cm deep /8" x 3" ) and line them with parchment paper.
To a medium saucepan add the ‘saucepan ingredients' (margarine, treacle, syrup and sugar) and warm until combined, around 5 minutes. Take the pan off of the heat and set it aside for 15 minutes to cool.
500 g dairy free margarine, 300 g treacle, 300 g golden syrup, 350 g soft light brown sugar
In a large bowl mix together the flour, baking powder and spices.
1 kg self raising flour, 1 tsp baking powder, 3 tbsp ginger, 4 tsp cinnamon, 2 tsp mixed spice
Once the liquid in the saucepan has cooled, add it to the dry mixture along with the dairy free milk.
500 ml dairy free milk
Stir well using a large whisk, until smooth and combined.
Divide the mixture between the two cake tins and bake for 65 minutes. Test the mixture with a skewer or knife - if the skewer/knife comes out clean your cakes are done, if there is cake mixture still on the skewer/knife then cook the cakes for another 5-10 minutes until the skewer/knife does come out clean.
Cool your cakes in the tins on the kitchen side. I like to make the cake the day before I want to decorate it because it needs to be completely cool before it can be decorated, plus it’s less to do all in one day.
When the cakes are completely cool (at least 4 hours), cut each cake in half horizontally to make four layers in total, and level out the top. The offcuts will provide tasty decorating sustenance!
