Ingredients

Cake:

  • 170g (6 oz) self-raising flour
  • 170g (6 oz) margarine (or butter), softened
  • 170g (6 oz) caster sugar
  • 3 medium eggs
  • 2 tsp instant coffee, dissolved in a small amount of boiling water (allow to cool)

Butter Icing:

  • 100g (3.5 oz) butter, softened
  • 200g (7 oz) icing sugar
  • 1-2 tsp instant coffee, dissolved in boiling water (cooled)

Decoration:

  • Walnut halves, for garnish

Instructions

1. Prepare the Cake Batter

  1. In a large mixing bowl, combine self-raising flour, margarine, caster sugar, and eggs. Mix until smooth.
  2. Add the cooled coffee mixture and blend thoroughly until the batter is uniform.

2. Prepare the Air Fryer

  1. Preheat your air fryer to 140°C (284°F) for about 3-5 minutes.
  2. Line the bottom of two 6-inch cake tins with baking parchment to prevent sticking. Grease the sides lightly with margarine or butter.

3. Bake the Cake

  1. Divide the batter evenly between the two prepared tins.
  2. Place the tins in the air fryer (you may need to bake them one at a time depending on the size of your air fryer).
  3. Bake at 140°C (284°F) for 45 minutes, or until a skewer inserted into the center comes out clean.

4. Cool the Cakes

  1. Remove the cakes from the air fryer and let them cool in the tins for 10 minutes.
  2. Transfer to a wire rack and allow to cool completely before frosting.

5. Make the Coffee Butter Icing

  1. In a bowl, beat the softened butter until creamy. Gradually add the icing sugar, mixing well after each addition.
  2. Stir in the cooled coffee mixture to achieve the desired flavor and consistency.

6. Assemble the Cake

  1. Spread half of the coffee butter icing on one layer of the cake.
  2. Place the second layer on top and spread the remaining icing over the top.
  3. Decorate with walnut halves for a classic finish.

Tips for Success

  • Adjust baking time as needed depending on your air fryer model. Check for doneness at 40 minutes to avoid overbaking.
  • For an extra nutty flavor, fold a handful of chopped walnuts into the batter.
