  • 3 medium eggs
  • 100 g | 3.5oz Canderel Sugarly
  • 200 g | 7oz finely grated potato such as Maris Piper
  • 100 g | 3.5oz ground almonds
  • 100 g | 3.5oz plain all purpose flour
  • 2 tsp baking powder
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 200 g | 7oz blueberries tossed in 1 tbsp flour
  • 80 g | 3oz flaked almonds
  • 3 tbsp apricot jam + 1 tbsp water optional


  • Preheat the oven to 180C (350F) and line a 20cm/8in square tin with baking paper.
  • Peel and grate the potato really finely and then squeeze some of the moisture out. Set aside.
  • Whisk the eggs and Canderel Sugarly together for 3-4 minutes at maximum speed until pale and double in volume.
  • Whisk in the grated potato until well combined.
  • Add the ground almonds, flour, baking powder, vanilla and salt and whisk until incorporated.
  • Fold in half the blueberries and pour the batter into the prepared tin.
  • Dot the remaining blueberries over the top, pushing them gently halfway into the batter. Sprinkle with the flaked almonds.
  • Bake for 30 minutes. Lift the cake out of the tin and transfer to a cooling rack.
  • Warm the jam and water in the microwave for 30 seconds and stir together. Carefully brush over the cake to glaze.
  • Cut into squares and serve. Keep any leftovers in an airtight container and consume within a day.
