Sweet and Tangy Mini Rhubarb Custard Bars Ingredients
For the Crust

How to Make Sweet and Tangy Mini Rhubarb Custard Bars
-
Prepare Crust: In a mixing bowl, combine cold butter, flour, sugar, and salt. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs. Press this mixture firmly into a greased baking dish and refrigerate for about 30 minutes to firm up.

Bake Crust: Preheat your oven to 350°F (175°C). Bake the chilled crust for about 15 minutes, or until it turns lightly golden at the edges. Allow it to cool while you prepare the filling.

Make Custard Filling: In a separate bowl, whisk together the eggs, sugar, heavy cream, vanilla extract, lemon zest, and chopped rhubarb until everything is smoothly blended and well-combined.
