Step 1: Make the Crust
Preheat oven to 350°F (175°C) and grease a 9x9-inch baking pan (or line with parchment paper).
In a bowl, mix flour, sugar, and salt. Cut in the cold butter until crumbly.
Press the mixture firmly into the pan. Bake for 15 minutes until lightly golden.
Step 2: Prepare the Rhubarb Custard Filling
In a bowl, whisk eggs, sugar, flour, vanilla, and salt until smooth.
Stir in the chopped rhubarb and pour over the pre-baked crust.
Step 3: Bake to Perfection
Bake for 35-40 minutes until the custard is set and the edges are golden.
Let it cool completely before slicing into squares.
Step 4: Serve & Enjoy!
Dust with powdered sugar for a pretty finish.
Serve with whipped cream or vanilla ice cream for extra decadence!
Pro Tips for the Best Rhubarb Custard Bars

🔹 Don’t overbake—the custard should be set but still slightly jiggly in the center.
🔹 Chill before cutting for cleaner slices.
🔹 Store in the fridge for up to 4 days (if they last that long!).
