Ingredients Method Notes

Ingredients
  

For the crust
  • 1 cup flour All-purpose flour works best.
  • 1/4 cup sugar
  • 1/2 cup butter, softened Ensure it's at room temperature for easier mixing.
For the filling
  • 1/2 cup brown sugar
  • 2 cups rhubarb, chopped Fresh rhubarb is preferred.
  • 1 cup sugar
  • 3 large eggs
  • 1/4 cup milk Any type of milk can be used.
  • 1/4 cup cornstarch
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking powder

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C) and lightly grease a 9×13 inch baking pan.
  2. In a mixing bowl, combine 1 cup of flour, 1/4 cup of sugar, and 1/2 cup of softened butter until crumbly. Press this mixture evenly into the bottom of the prepared baking pan.
Filling
  1. In a separate bowl, mix together 1/2 cup of brown sugar, 2 cups of chopped rhubarb, 3 eggs, 1/4 cup of milk, 1/4 cup of cornstarch, 1 teaspoon of vanilla extract, and 1/2 teaspoon of baking powder.
  2. Pour the rhubarb and custard mixture over the crust in the pan, ensuring even distribution.
Baking
  1. Bake for 30-35 minutes until the custard is set and has a light golden color. A toothpick inserted in the center should come out clean.
  2. Allow the dessert to cool in the pan before cutting into bars. For best texture, let them cool completely.

Notes

Serve chilled or at room temperature. Pair with whipped cream or vanilla ice cream for added richness. Garnish with fresh mint or powdered sugar if desired.
