Instructions

Preheat oven to 400°F (200°C)
Grease a 9×13″ baking dish
Whisk 2 cups flour, 1 tbsp baking powder, and 1/2 tsp salt in a bowl
Blend in 2/3 cup cold butter until crumbly with a crumb-like texture
Stir in 1 egg and 1/2 cup sugar until just combined
Press mixture into baking dish using a measuring cup handle for even thickness
Combine rhubarb slices, 1/2 cup sugar, lemon zest and juice in a saucepan
Simmer over medium heat for 3-4 minutes
Add 2 1/2 tsp cornstarch, stir until filling becomes glossy (total 5 minutes cooking)
Let rhubarb filling cool for 5 minutes
Spread filling over the chilled shortbread base
Mix 1 cup oats, 1/2 cup sugar, 1 tsp vanilla, 1/2 tsp cinnamon, and 1/2 cup melted butter until crumbly
Sprinkle topping over filling
Optionally press topping into filling for better adhesion
Bake for 20-25 minutes until golden-brown and bubbly
Cool for 15-20 minutes before slicing into bars

Notes

No-stick pan or parchment paper helps prevent browning under the bars
Adjust rhubarb to 1:/2-inch thicker slices for higher-tart contrast
Swap 1/2 cup rolled oats + 1 tbsp coconut oil for a nut-free version
Add 1 tbsp extra lemon zest if using the base mixture dry for more citrus flavor
Store in an airtight container at room temperature for 3-4 days
