How to prepare

1
Heat the oven to 180°C. Grease a 23 cm square baking pan and line the base with parchment, leaving two edges overhanging for lifting.
2
Whisk 120 g of the flour, 50 g of the granulated sugar, the baking powder, and half of the salt in a bowl. Mix in 75 g of the softened butter, the beaten egg, and vanilla until a soft, sticky dough forms. Press it evenly into the prepared pan.
3
Toss the rhubarb with the remaining 100 g of granulated sugar, cornstarch, and remaining salt. Spread it evenly over the dough, keeping the fruit layer level from corner to corner.
4
Mix the remaining 60 g of flour with the oats, brown sugar, and cinnamon. Rub in the remaining 40 g of softened butter with your fingertips until coarse, moist crumbs form, then scatter them over the rhubarb.
5
Bake on the center rack for 40 to 45 minutes, until the streusel is deeply golden and the rhubarb juices bubble visibly around the edges. The center should feel set when the pan is gently nudged.

Cool in the pan for at least 30 minutes, then lift it out by the parchment and cut into eight squares. Serve warm or at room temperature.

Why this recipe works

A thin layer of cornstarch keeps the juicy rhubarb from overwhelming the tender base, while oats and brown sugar give the streusel a toasty, gently chewy contrast.
