Plum Hazelnut Crumble Cake

The cake requires only half of the plum filling. The rest I used to make 4 individual ramekin crumble. So you might want to make an extra portion of streusel for the ramekins later. They're excellent with a scoop of vanilla ice cream or chantilly cream. A scrumptious single-serving dessert without the mess, perfect for portion control, satisfying, and guilt-free.

Filling	Crust and Crumble
2 tbsp Butter 300 g / about 2 cups Chopped fresh plums 2 tbsp Coconut sugar 1 tsp Vanilla paste 1/2 tsp cinnamon A large pinch nutmeg 2 Plums, stoned and chopped	150 g Refined spelt flour 30 g Hazelnut meal 2 tbsp Coconut sugar Pinch of sea salt 100 g Butter, lightly softened 1 tsp Vanilla paste 1 tbsp Chopped hazelnuts, optional

Melt the butter in a heavy-based pan and add the remaining filling ingredients, except 2 plums. Simmer for 10-15 minutes or until the plums are cooked, some of the liquid evaporates and the mixture becomes a bit jammy. Set aside to cool.
Heat oven to 190C/375F, and line a 20-22cm springform pan with parchment paper. In a mixing bowl, stir together the spelt flour, hazelnut meal, coconut sugar and sea salt. Cut in butter and vanilla paste. Rub everything together until the mixture forms streusel-like crumbs.
Press 2/3 of the crust into the bottom of the prepared pan, reserving the rest for the topping.
Spread cooled plum jam in an even layer over crust. Top with the chopped plums, then sprinkle remaining streusel mixture over top of fruit. (the cake requires only half of the plum filling. Use the rest to make individual ramekin crumbls or for breakfast) Sprinkle some chopped hazelnuts over if using.
Bake until jam bubbles at edges and topping is lightly browned, 30 to 35 minutes. Cool completely before slicing into bars or wedges.
