Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish and set aside.
In a medium mixing bowl, combine 1.5 cups of all-purpose flour and 0.5 cups of powdered sugar. Stir to combine.
Add 0.75 cups of melted unsalted butter to the flour mixture. Mix with a fork until the dough comes together and resembles coarse crumbs.
Press the mixture evenly into the bottom of the prepared baking dish to form the cookie crust.
Bake the crust in the preheated oven for 15 minutes, or until lightly golden. Remove from the oven and set aside to cool slightly.
While the crust is baking, prepare the topping. In a large bowl, combine 3.5 cups of diced fresh rhubarb, 1.5 cups of granulated sugar, and 0.25 cups of all-purpose flour. Stir to coat the rhubarb evenly.
Pour the rhubarb mixture evenly over the baked crust.
In a separate bowl, whisk together 3 beaten eggs, 1 cup of heavy whipping cream, and 1 teaspoon of vanilla extract until smooth.
Pour the custard mixture evenly over the rhubarb layer.
Bake in the preheated oven for 35-40 minutes, or until the custard is set and the edges are slightly golden.
Remove from the oven and allow the dessert to cool completely to room temperature. For best results, chill in the refrigerator for at least 1 hour before serving.
Cut into squares and serve cold as a refreshing summertime dessert!
