Easy summer fruit tart- this tart balances the ripe juicy sweetness and bright acidity of plums and apricots in a soft, and sweet sponge cake filling. All of this is encased in a buttery, crumbly tart shell! This is a perfect summer dessert to celebrate seasonal fruits!
Combine the flour and sugar in a large bowl. Rub the chilled butter in the mixture, using your fingertips. When it resembles coarse breadcrumbs, add iced cold water, 1 Tbsp at a time, just enough to bind the dough. It can be a bit scraggy at this point but don’t worry, it will come together. Using the palm of your hand, push the dough away from you 4-5 times until its smooth.
Roll into a ball and flatten it into a disk. Wrap in clingwrap and refrigerate for 15-20 minutes.
Sponge filling
Beat together the butter and sugar in a bowl.
Add the egg and vanilla extract, mix well.
Fold in the flour and baking powder.
Assembly
Preheat your oven to 180C.
On a lightly floured surface, roll out the dough to about a 10"/11" circle.
Place the dough gently into an 8" pie pan. Trim the edges of the pastry to fit the sides of the pan.
Spoon the sponge filling into the pie, spread evenly.
Place the cut fruits on top and sprinkle with a tablespoon of caster sugar (optional).
Bake for 45-50 minutes at 170 C, until the sponge and pastry is golden.
Let the tart rest for 15-20 minutes before taking it out of the pan.
