Method

You’ll need: oven · springform tin · chopping board · knife

1. Preheat the oven to 175 °C (155 °C fan) and line the base of a 26 cm springform tin with baking paper.
2. Quickly knead the ingredients for the base into a smooth dough. Press it into the tin and push it 3 cm up the sides.
3. Stir the low-fat quark, eggs, honey, cornflour and vanilla powder until smooth and spread the quark cream over the base.
4. Halve and stone the plums and lay them close together on the cream, cut side up.
5. Rub the oats, wholemeal spelt flour, cold butter, coconut sugar and cinnamon together with your fingers into a crumble and scatter it over the plums.
6. Bake the cake in the oven at 175 °C for 50 min, until the crumble is golden brown. Leave it to cool completely in the tin and cut it into twelve slices.

Swaps

Plums → apples, or frozen plums (out of season). Low-fat quark → skyr (firmer). Honey → maple syrup. Wholemeal spelt flour → white spelt flour (paler, fluffier).

Cooking tips

Lay the plums cut side up, so the juice stays in the fruit and the base doesn't go soggy. Only cut the cake once it's cold, otherwise the quark cream is too soft.
