Chocolate Orange Marmalade Cake (gluten-free)

This fudgy Chocolate Orange Marmalade Cake is gloriously rich and chocolatey with an unmistakable tangy orange kick. It is made here with an easy gluten-free flour blend (although you can sub with an all purpose flour). Either way the cake has a gorgeously moist texture with an indulgent chocolate orange flavour. Perfect for any time of day and every occasion.

Notes

Ingredients
Chocolate. You can use any type of dark chocolate in this recipe. Both 70% and 54% work very well.
Marmalade. You can use any type of orange marmalade. Sweet orange marmalade (which is my preference) will contribute more sweetness. A bitter marmalade like Seville Orange Marmalade can add a more tangy and complex flavour.
Eggs. The eggs used in this recipe are medium size, 60g with shell and 50g without shell. If you can't get hold of medium eggs I suggest you weigh the amount.
Flour. This cake has been tested with my Homemade Gluten-Free Flour Blend. However, you can swap the flour for plain all purpose flour if you do not need it to be gluten-free.
How to Make it Dairy-Free
Swap out the Greek yoghurt for a natural coconut yoghurt. Also, make sure to choose a dairy-free dark chocolate.
Important tips
I have included even more in depth tips and troubleshooting in the full post above.
  • Make sure all the ingredients are at room temperature otherwise the chocolate will seize when it is added in.
  • Keep a close eye on the cake as it bakes. Since oven temperatures can vary, start checking for doneness a few minutes before the recommended time to avoid overcooking. A wooden stick inserted into the centre should come out with a few moist crumbs, indicating the cake is done. If the stick is dry then it is overbaked.
  • If you are making the Candied Orange Slices for the decoration then you can switch out the marmalade glaze and instead use the leftover orange syrup from making that recipe.
How to make ahead and store
It keeps incredibly well for up to 5 days. Store the cake in an airtight container (preferably not plastic) in a cool dark place.
How to freeze
You can freeze the cake successfully by double wrapping it. First wrap it tightly in plastic wrap then aluminium foil. Then either place in a resealable freezer bag or airtight container. Don’t forget to label including the date. To enjoy, thaw in the refrigerator overnight, allowing it to come to room temperature before serving.
