Method

  1. Heat the oven to 180C/160C fan/gas 4. Butter and line two loose-bottomed 20cm round cake tins. 

  2. Put the butter and sugar in a large mixing bowl. Beat for 5 mins with an electric whisk until pale and fluffy. Whisk in the eggs one at a time, then fold through the flour, grated lime zest and yogurt. Divide the batter between the prepared tins and bake in the centre of the oven for 25-30 mins, or until a skewer inserted in the middle comes out clean. Leave in the tins for a min, then turn out onto wire racks. 

  3. To make the syrup, put half the lime juice and all the sugar and mint leaves into a saucepan and bring to a simmer, adding 1 tbsp water if needed to dissolve the sugar. Gently bubble for 7-10 mins, or until syrupy. Remove from the heat and stir through the rum and remaining lime juice. Leave to infuse for 10 mins, then strain into a bowl. 

  4. Prick the warm cakes all over with a cocktail stick and pour over the syrup. Leave to cool completely.

  5. To make the buttercream, put the butter, icing sugar and lime zest in a bowl and beat with an electric whisk for 5 mins until light and fluffy. Beat in the cream cheese until just combined, being careful not to overbeat.  

  6. Put one of the syrup-soaked sponges on a large serving plate and spoon over one-third of the buttercream, spreading it over with a palette knife. Top with the other sponge and spread the remaining icing over the top and sides of the cake. Decorate with the lime wedges, lime zest and mint leaves. Will keep in the fridge for up to three days.

I ended up with a lovely, moist, zingy cake! Slight error in that I added the rum to the pan and cooked it.......but still tasted delicious. Definitely going to make again

Ok, I have now made the cake, putting the zest of the limes in where it said “grated”. I figured that using literally the whole lime would make it very bitter and probably inedible, but the recipe is very poorly written and not at all clear - it’s the fact that the methodology says to “add the grated limes” which really does imply that the whole lime goes in but this is surely not the plan? It was ok. I used all the syrup which made the cake rather stodgy and very sweet. And you couldn’t really taste the rum. I ran out of icing sugar so halved all the quantities for the icing and this was perfect for sandwiching the cakes and icing the top. However, I also added a bit more cream cheese I prefer a more savoury/salty taste and there really wasn’t much in it in the first place - you can do all that to taste though. Personally, I love a Cream cheese icing! I don’t think i’d Do the cake again as it is. I’m not generally very adventurous with tweaking recipes but if I had to, I think I’d make a lime curd for the middle, a cheesier icing for the top, and I wouldn’t bother with the syrup - although a bit of rum (neat) sprinkled over might create more of the mojito taste if that’s what you’re after.

A really lovely cake, I did add 1tsp of baking powder as I usually use this. Didn't need all the syrup, will only make half quantity of it next time.

For the first part of the recipe it says "grate the limes" I may be stupid but is that the whole lime or the flesh of the lime or the just the skin (which would be zesting and that is mentioned later on so I suppose not) I am confused.

I’d like to reiterate the question already posed - what does it mean by “grated limes”? Not only in the list of ingredients, but also in the method - add the grated limes, which suggests that the whole limes have been grated. Really not sure about this as I fear it would ruin the cake if wrong. Please can someone clarify?!!

Thanks for pointing this out. We have clarified the recipe - the zest of two limes are to be used in the cake mixture.
