You will need
Directions
Preheat oven to 190C/170C fan/gas 5.
First, prepare the orange jelly layer by melting the marmalade in a heavy-bottomed saucepan and placing over a low heat. Partially dissolve the gelatine leaves in 250ml tepid water before pouring into the melted marmalade and stir until completely dissolved.
Pour the marmalade jelly into the baking tray prepared with cling film and set aside to slightly cool. Once cool enough, place in the fridge and allow to set for 2 hours.
In the meantime, make the sponge. Cream together the butter, sugar and vanilla until light and fluffy. Crack in one egg along with a tablespoon of flour and briefly whisk just until combined.
Repeat this with the remaining 3 eggs.
Once all the eggs are combined, add the remaining flour, baking powder and milk to the batter and whisk on high just until the ingredients have combined into a thick, smooth batter.
Spoon the batter into the baking tray prepared with baking paper and level and smooth the top using a palette knife or the back of a spoon. Place in the oven to bake for 25 - 30 minutes until golden, risen and cooked through. Remove from oven and allow to full cool in the tin.
Once the jelly layer is set and the cake is completely cool, prepare the chocolate ready for layering. Break up the chocolate into a heat-proof bowl and add the coconut oil. Either melt in the microwave in 30 second intervals, stirring regularly, or over a Bain-marie.
Keeping the sponge in its tin, flip the set jelly out of its tin on top of the sponge, remove tin and clingfilm so it sits perfectly atop the cake. Pour the melted chocolate over the top of the jelly layer, encouraging it to the edges if needed. Grate over the orange zest and return to the fridge until the chocolate has fully set.
When all the layers are chilled and set, remove from the fridge and allow to come to room temperature. Using a hot, sharp knife, slice into 12 generous fingers and serve.
Recipe Note
If the chocolate is too warm when poured over the orange layer, is tends to melt the
jelly. Once the chocolate has melted, allow it to sit on the side for 5 minutes to slightly cool to
avoid this.
Try to heat your knife as much as possible to ensure the chocolate layer doesn’t crack too
much when slicing into fingers. However, a little bit of cracking is fine - it shows it's homemade with love!
