Grease a small springform pan (20 cm Ø) and sprinkle with coconut flakes. Sort blueberries, wash and dab dry. Stir the fat, diabetic sweetener, salt and lemon peel for about 5 minutes until creamy. Stir in eggs one after the other. Mix flour and baking powder and sieve. Alternate briefly with the mineral water. Stir in 75 g blueberries.
Fill the dough into the springform pan. Spread the remaining 50 g blueberries on the dough. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 30-35 minutes. Sprinkle coconut chips onto the cake about 5 minutes before the end of the baking time. Remove the cake from the oven, let it cool in the mould for about 10 minutes, then remove from the mould. Let it cool down
