How to make
With a wire whisk, thoroughly beat the eggs in a large bowl for a few minutes. Pour the brown sugar and leave it to dissolve (if there are any lumps, crush them).
Peel and cut apples into cubes. Add them along with the cinnamon, vanilla and cardamom. If desired, you can diversify the delicious apple sponge cake with a handful of crushed nuts. Evenly mix everything with whole grain flour, until a homogeneous mixture is obtained.
Pour the mixture into a baking pan with a size of about 80°F (25 cm) in diameter, which is have smeared with sunflower oil and sprinkled with whole grain flour. Bake at 360°F (180°C) for about 30 minutes.
After it is ready, cut the cake into 6-8 pieces and serve it completely cooled and sprinkled with powdered sugar (using a sieve or a fine strainer).
It's even tastier if you serve the Sponge Cake with Whole Grain Flour and Apples with a glass of freshly made apple smoothie!
