This recipe is inspired by the coffee, cardamom and walnut cake in Fiona Cairn’s beautiful book Seasonal Baking (which I wholeheartedly recommend). I love baking with seasonal ingredients and the caramel and walnut decoration reminds me of golden autumn leaves. This is the perfect cake to have with a warming coffee after a brisk walk in the park on a Sunday afternoon!
In addition to making it dairy-free (of course!) I substituted the buttercream with a soya-based coffee and cardamom cream, which is lighter and less sugar-heavy.
The round and warm scent of cardamom makes a good addition to autumn and winter bakes (have a look at my Swedish cardamom and cinnamon buns). For this recipe you will need the dark brown seeds inside the cardamom pods. Although supermarkets generally sells the green pods, rather than the seeds, there is no need to go through the fastidious process of de-seeding the pods, as the seeds are easily available online, including via Amazon. It is important to ground the seeds immediately before use, to keep their flavour intact.
Ingredients (for 6-8 people)
275g caster sugar
275g icing sugar
175g margarine, plus more for the tin
100g walnuts halves
100g ground almonds
6 tsp (about 30 g) freshly ground cardamom
4 tbsp (about 50ml) decaf coffee
3 tbsp (about 40ml) whipped soy single cream
1tsp vanilla extract
1 bag (7gr) baking powder
How to make it
1. Prepare the ingredients: cut 175g margarine in pieces and leave it out to soften; roughly chop 50g walnuts; sieve together 125g flour and 1 bag (7gr) baking powder. Grease a 20cm round cake tin and line with baking parchment.
2. Preheat the oven to 180°C / fan 160°C / gas mark 4. Keeping them separate, place both the 50g walnut halves and the 50g chopped walnuts on baking trays and roast for six minutes. Cool.
3. Using a food mixed or an electric whisk, cream together 175g margarine, 175g caster sugar and 1 tablespoon decaf coffee until very light and fluffy. Lightly beat 3 eggs, then add them to the mixture. Gradually add 50g ground almonds and 3 teaspoons freshly ground cardamom. Gently fold in the flour-baking powder mix and 50g chopped walnuts; don’t over-mix.
4. Pour into the tin and bake at 160°C (fan) for 60 min, or until a skewer comes out clean. Cool on a wire rack.
5. Prepare the caramelised walnuts: lay 50g walnut halves on a baking tray lined with baking parchment. Put 100g of caster sugar and 100ml of cold water in a saucepan and dissolve the sugar over a gentle heat, stirring with a metal spoon. Increase the heat to a boil, stop stirring and occasionally brush the sides of the pan with a pastry brush dipped in cold water, to prevent crystals forming. Boil until the mixture turns a beautiful caramel gold and has thickened.
6. Have a sink or washing-up bowl of cold water to hand. Plunge the base of the pan into the cold water, then, using a teaspoon, drizzle the caramel over the walnuts on the tray and leave to set.
7. For the coffee and cardamom cream, mix 275g icing sugar (sifted), 50g ground almonds and 3 teaspoons ground cardamom. Using a food mixed or an electric whisk, add 3 tablespoons decaf coffee and 3 tablespoons whipped soy cream. If it is too runny, add more icing sugar. If it is too stiff, add more whipped soy cream, until it reaches the desired texture.
8. When the cake is completely cool, cut it in half horizontally. Spread half of the coffee and cardamom cream over the bottom half, then place one half over the other. Spread the other half of the coffee and cardamom cream on top.
9. Decorate with the caramelised walnuts and the caramel shards. Enjoy!
