Mini Chocolate, Coffee and Walnut Cakes for Mac


I've got to say these aren't my normal straight forward no nonsense kind of bake, but I've been promising Mac who helps look after everything for me along with Fiona and Ali, a coffee and walnut cake for ages, so I thought I needed to pull out all the stops, and then I started to think about how to make something special and got slightly swept away. These little treats have 2 layers of coffee and walnut cake, a layer of walnut shortbread, coffee buttercream all finished with a crisp coating of Belgium chocolate. There will be quite a lot of left over edges, and I know it's really wasteful, unless like me you eat them, but this is a special occasion bake not one for everyday.
Preheat the oven to 170

Coffee and walnut sponge
200g S/R flour
200g stork
200g caster sugar
1 shot of expresso or 2 tsp instant coffee mixed with 2 tbsp boiling water
50g finely chopped walnuts
2 eggs
Mix all of the above together, in either a free standing machine or with a hand whisk until light and fluffy, spoon into a 8 inch greased sandwich tin.
Bake @ 170 for 25 mins or until springs back in the centre when gently pushed, turn out and chill completely

Walnut shortbread
100g plain flour
100g unsalted softened butter
50g chopped walnuts
50g caster sugar
In a food processor blend all of the above ingredients together.

200g Icing sugar
100g unsalted softened butter
1 shot of expresso or 2 tsp instant mixed with 1 tbsp hot water

You will also need 50g chopped walnuts

Line a baking tray with parchment, cut the sponge into 6 circles using a 3 inch cutter, then cut the sponge circles through the middle, Spoon the buttercream into a piping bag and snip of the end,  pipe swirls onto half of the sponge circles, sprinkle with finely chopped walnuts


 Brush the shortbread with melted chocolate, this will help keep the biscuit crisp. Then place onto  the buttercream.
Pipe with another ring of buttercream and top with walnuts.

Add another disc of sponge and a swirl of buttercream, try to create a little dome shape. Place all of the stacks into the freezer and chill until solid to the touch, about 45-60 minutes










Place the sponge stacks onto wire racks with a
 baking tray placed under it, Pour melted chocolate over each cake until all enclosed, pop back onto the parchment lined trays and chill until set.
