Ingredients

  • 200 g soft light brown sugar
  • 200 g unsalted butter room temperature
  • 4 eggs medium - 60g each with shell
  • 125 g teff flour
  • 100 g walnuts plus extra to decorate
  • 50 g tapioca flour
  • teaspoons baking powder
  • ¼ teaspoon salt
  • 2 tablespoons instant coffee powder

Icing

  • 300 g unsalted butter room temperature
  • 300 g icing sugar
  • 1 tablespoon instant coffee powder
  • teaspoon salt

Instructions

  • Pre-heat the oven to 180°C/ 160°C fan and line and grease 2 x 20cm round cake tins.
  • Beat the sugar and butter together until light and fluffy.
  • Add the eggs one at a time until combined.
  • Place the walnuts in the food processor and grind them until they form fine crumbles.
  • Pour the ground walnuts into a large bowl then whisk to mix with the teff flour, tapioca flour, baking powder, salt and coffee powder.
  • Add the flour mix to the batter and mix until completely combined.
  • Divide the batter between the cake tins and bake for 20-25 minutes until an inserted toothpick comes out clean.
  • Remove from the oven and leave the cake layers to cool completely before icing.

Icing

  • Beat the butter together with the icing sugar and mix until incredibly light and fluffy.
  • Mix in the espresso powder and salt.
  • To assemble, divide the icing between the middle and the top of the cake and decorate with walnut halves.

Notes

  • WALNUTS: If your walnuts start to turn to butter in the corners of the food processor then you have taken them too far.
  • The instant coffee powder I use is Nescafe Azera.
  • This cake will keep for up to 3 days in an airtight container.
  • You can freeze this cake for up to 2 months.

Ingredient measurements

  • Please note when you see ‘grams’ listed as opposed to ‘millilitres,’ or any other term of measurement, that is not incorrect. I weigh all of my ingredients, including liquids, for accuracy.
  • US customary measurements for the ingredients provided are based on a conversion calculator. This recipe was tested with metric measurements and I recommend using a digital scale to weigh ingredients for the most accurate results.
