Gluten-Free Mojito Cake with Captain Morgan’s Spiced Rum

EatsLeeds Gluten Free Mojito Cake Recipe - Moist Gluten free cake

Who doesn’t love a good mojito? This naturally gluten-free mojito cake is a delicious crowd-pleaser. Enjoy!

The lovely peeps over at Diageo sent me a sample of Captain Morgan’s a while back, for use in a recipe. I’ve been experimenting with polenta and rum cakes for a while now and, I think I have finally perfected this gluten-free mojito cake – it is delicious!EatsLeeds Gluten Free Mojito Cake Recipe - Gluten free cake

I love spiced rum. Not only does it make me feel like a pirate, but rum-and-ginger is one of my go-to drinks when I’m not in the mood for beer, and a mojito is the first thing I order when I go on holiday. I love the twist of a spiced mojito,  and you can never have too much cake, so today I’m sharing my recipe for a gluten-free mojito cake.

I know, gluten-free cakes don’t sound like the most exciting thing ever – and when well-meaning people straight-up substitute all-purpose gluten-free flour into a regular cake recipe, it’s usually just a dry, tasteless mess. But cakes like this, made with whole ingredients, that are naturally gluten-free (polenta, ground nuts, and so-on) are hands-down some of my favourite cakes ever, and can hold their own next to lord it over ‘regular’ cakes (I’m looking at you, dry and boring victoria sponges…).EatsLeeds Gluten Free Mojito Cake Recipe - Gluten free cake with Captain Morgans Spiced Rum

Note: the basic polenta cake recipe is one I’ve been using for years, in various forms, and inspired by a lemon polenta cake from good old Nigella

For the Cake
  1. 200g Soft, Unsalted Butter
  2. 200g demerara sugar
  3. 100g polenta
  4. 150g ground almonds
  5. 50g dessicated coconut
  6. 3 eggs
  7. 1.5 tsp. Gluten-Free Baking Powder
  8. Zest of 2 Limes
  9. 1 tbsp. Fresh Mint
  10. 4 tbsp. Captain Morgan's Spiced Rum
For the Syrup
  1. Juice of Two Limes
  2. 4 tbsp. Captain Morgan's Spice Rum
  3. 125g Icing Sugar
  4. 1 tbsp. Fresh Mint
  1. First, pheheat the oven to 160°C, then blend the butter and sugar. Protip: you can totally do this whole cake in a blender if you don't have a hand whisk - just make sure to cut the butter down into small chunks
  2. Then, in a separate bowl, mix the remaining dry ingredients (the polenta, coconut and almonds) together.
  3. Add an egg to the mix in the blender, then one third of the dry ingredients, and continue to blend. Add the next egg and 1 third of the dry ingredients, then blend again, and add the final egg and third of the dry ingredients and blend well to combine.
  4. Add the baking powder, lime zest, mint and rum, scrape down the sides of the blender, and give it a final pulse - you should now have a thick (and delicious-smelling) batter.
  5. Grease a cake tin, then pour the cake batter into the tin, put in the middle shelf of the oven, and bake for 40 minutes, until the cake is golden-brown on top.
  6. Meanwhile, make the syrup: Add all the syrup ingredients to a small saucepan, bring to the boil, then simmer for 10-15 minutes, making sure to stir so it doesn't boil over.
  7. Remove the cake from the oven and lave to cool a little - you want it touchable but still warm. Turn out onto your serving plate, then prick the top and pour over the syrup. Shimmer over a little icing sugar and garnish with fresh mint and lime. Grab a slice while it's still warm!
Enjoy a slice of gluten-free mojito cake with a large coffee, or you know, an actual mojito. This cake will save for five days in an airtight container (I mean, it won’t in my house, but theoretically it could).
