Chilli and chocolate were meant for each other. The Aztecs would mix cocoa beans and chilli peppers to make a spiced cocoa drink and we all know how prosperous the Aztecs are today so no reason not to carry on the tradition! Umm, yes.

This is a classic chocolate cake spiced up with fresh and dried chilli peppers. This isn’t a cake with the tiniest hint of chilli, this is a chilli chocolate cake. It’s not hot, it doesn’t burn but it has a distinct chilli flavour and mild heat mixed with the richness of dark chocolate.
Ingredients
The Sponge:
175g wholemeal self raising flour
175g soft light brown sugar
175g soft unsalted butter
3 large eggs, beaten
1 heaped tablespoon of cocoa powder
1 teaspoon of baking powder
1 red chilli pepper, very finely chopped (sweet, mild chillis will work better than fiery ones)
1/2 teaspoon of dried chilli flakes
The Filling & Frosting:
250g dark chocolate (use chilli chocolate if you can find it, e.g. Montezuma’s Chilli Chocolate or Lindt Chilli Chocolate)
250ml double cream
1 small knob of butter (roughly the size of a large heaped tablespoon)
1 red chilli pepper, very finely chopped
1/2 teaspoon of hot chilli powder
1/2 teaspoon of dried chilli flakes
To decorate I used a handful of crushed pistachio nuts and half a finely chopped red chilli
The baking tins I used were two 7 inch round sandwich tins, lined with greaseproof paper.

Method
The cake itself is a basic sponge recipe, with chilli.
Sift the flour, cocoa powder and baking powder into a mixing bowl.
Add the sugar, butter, eggs, fresh chilli and dried chilli. Beat this together until you end up with a soft mixture that falls off a spoon when you hit it against the bowl. Add a drop or two of water if you think your mixture is too stiff.
Divide the mixture into two baking tins (I recommend 7 inch diameter) and bake at 170 degrees C (325F) for 30 minutes, or until springy in the centre and a knife inserted into the sponge comes out clear. Don’t worry if the mixture looks like it isn’t enough. Remember that this is made with self-raising flour and baking powder. It will rise and expand to fill the tins.
When the cakes are done take them out of the baking tins and allow to cool before decorating.
To make your filling for the middle and frosting for the top melt the chocolate over a medium heat. My method of doing this is to boil a pan of water and put a heat proof bowl on top of the pan, drop the chocolate in the bowl and stir until melted.

Once melted take the chocolate off the heat. Stir in the chillis, butter and cream. Cover with cling film and allow it to cool. When cooled, put the mixture in to the fridge for around an hour or until thickened enough to easily spread (but not set hard).
When thickened, spread the chocolate mixture as a filling and topping for your cake. Decorate with crushed pistachios and finely chopped fresh red chillis. Enjoy!

How Spicy Will This Be?
The recipe above is what I would call a mild to medium chilli spice. It’s doesn’t burn and isn’t as strong as chilli can be in savoury dishes. If you don’t like spicy food you probably won’t like this, but at the same time it won’t blow your head off.
Also remember that depending on how much of a chilli fiend you are, you can alter the amount of chilli you add to the cake. For the less fiendish among you, just using melted chilli chocolate for the filling & topping might be enough or if you’re a hardcore chilli fan you might want to experiment with more chilli powder in the sponge.
What Kind of Chillis Should I Use?
I recommend using sweet chilli peppers with a medium heat. The real heat will come from the chilli flakes and powder and the fresh chillis will add both texture and sweetness to the sponge and frosting.
I actually tried an experiment by putting popping candy in the middle of the sponge with the chocolate filling, but it failed to have any effect whatsoever so I’ve left this out of the recipe and have eaten the remaining popping candy. It was great.
