A delightful dessert combining the tartness of rhubarb with a sweet custard filling on a buttery crust.
Preheat your oven to 350°F (175°C).
Ensure your oven is fully preheated before baking for even cooking.
In a mixing bowl, combine the flour, melted butter, and powdered sugar until a dough forms.
Mix until the dough is just combined to avoid overworking it.
Press the dough evenly into a 9x13 inch baking pan.
Use the back of a spoon or your hands to spread the dough evenly.
Bake the crust in the preheated oven for 15 minutes, then remove and let it cool slightly.
Allow the crust to cool slightly before adding the filling to prevent it from becoming soggy.
In another bowl, whisk together the eggs, sugar, flour, and salt until smooth.
Whisk thoroughly to ensure the filling is well combined and smooth.
Fold in the rhubarb pieces into the filling mixture.
Ensure the rhubarb is evenly distributed for consistent flavor in every bite.
Pour the filling over the baked crust and spread evenly.
Use a spatula to spread the filling evenly over the crust.
Bake in the oven for 45 minutes or until the filling is set and slightly golden.
Check for doneness by gently shaking the pan; the filling should not jiggle.
Let the bars cool completely before slicing and serving.
Cooling completely ensures clean slices and better flavor.
