Coffee, walnut, and cardamom cake

Coffee and walnut cake

Macmillan Cancer Support have supplied this delicious recipe to get us excited for their flagship event, World’s Biggest Coffee Morning later this month.

This year, World’s Biggest Coffee Morning takes place on Friday 27th September (but you can host it whenever you want).

Every Coffee Morning comes in different shapes, sizes and slices! From good old coffee and cake, to a posh prosecco tea-party and everything in-between. However you host it, your Coffee Morning is a fun way to get your friends and loved ones together to support a great cause. Each pound donated means Macmillan can be there for more people affected by cancer.


Make the cake

  1. Preheat oven to 160C Fan /180C/350F/GM4
  2. Combine flour, ground walnuts, ground coffee and salt in a bowl.
  3. In a large bowl or food mixer, cream butter and sugar until pale and fluffy.
  4. On medium speed, add eggs a tablespoon at a time, mixing well between each addition. Add a teaspoon of milk if the cake batter looks like curdling.
  5. On the lowest speed, add the flour mixture until just combined (10 secs).
  6. Evenly fill the tins (weigh each tin if you want to be precise) and smooth the surface with palette knife or back of a spoon.
  7. Bake in the centre of the oven for 30 until a skewer comes out cleanly and top springy to touch.
  8. Remove cakes from the oven, leave the cakes in the tins for a couple of minutes turn out on to a wire rack to cool completely.
  9. Wrap the cakes in cling film and rest overnight at room temperature before icing.

Prepare the cardamom syrup

  1. Place the caster sugar and water in a small saucepan and over a low heat, dissolve the sugar completely. Then bring to the boil for a couple of minutes.
  2. Remove from the heat, add the ground cardamom and set aside.

Make the buttercream

  1. Place the unsalted butter in bowl or food mixer and beat until pale and light in texture.
  2. Add the sifted icing sugar in 3 batches, beating well between each addition, until the buttercream has increased in volume and is very pale and fluffy.
  3. Add the coffee mixture and beat again to mix.

Combine everything

  1. Place one cake half upper side down on a serving plate, generously brush with the syrup.
  2. Sandwich the cakes together using half the buttercream.
  3. Place on the top layer, brush again with syrup and decorate with the remaining buttercream and walnut pieces.
