Preheat the cooking oil between 150 °C (302 °F) and 160 °C (320 °F). Sift 70 g dark brown sugar into a large mixing bowl using a sieve, use a spatula to help work the lumps through. If your sugar is especially lumpy, place it in a sealable freezer bag and break the clumps with a rolling pin. Alternatively, cut it with a knife on a cutting board until fine.
Crack 1 egg into the bowl of sugar and add ½ tbsp cooking oil. Whisk thoroughly until smooth and well incorporated.
In a separate bowl, mix 125 g unbleached cake flour and 1 tsp baking powder together until well distributed.
Sift the dry ingredients into the wet ingredients and add 1 pinch salt. Mix everything together using a spatula until a dough is formed. It should have the consistency of soft cookie dough.
Divide the dough into equal pieces (I make twelve) and lay them on a silicone baking mat or greaseproof paper.
Once the oil is ready, lightly grease your hands with oil and roll each piece into a ball before carefully placing it in the oil.
Deep fry until golden and cracked. This will take about 4-5 minutes. When they are ready, they should float and roll around in the oil. If you are unsure, take one out and pierce with a skewer, it should come out clean.
Transfer to a wire rack to drain any excess oil.
Serve and enjoy!
