For the Pie Crust

  • 1 1/4 cups all-purpose flour
  • 1 tsp sugar optional
  • 1/2 tsp salt
  • 8 tbsp butter chilled & cut into small pieces
  • 4-6 tbsp water chilled

For the Rhubarb Custard


  • In a mixing bowl, combine the 1 1/4 cups of flour, add 1/2 teaspoon of salt, and 1 teaspoon sugar. Whisk thoroughly.
  • Now, add 8 tablespoons of cut butter and mix with the flour mixture using your fingers or a pastry blender. 
  • Pour 4 tablespoons of chilled water and bring the dough together. Add more chilled water, if needed. Pat the dough with some flour and press until it is smooth. Flatten the dough and refrigerate for half an hour.
  • Heat the oven to 200ºC. Remove the dough and roll out into a circle. Line a 9-inch pie plate with the dough and crimp as desired.
  • Now, in another large bowl, combine diced rhubarb, sugar, salt, flour, and nutmeg. Mix them well.
  • Whisk eggs in a bowl with milk. Add the mixture to the rhubarb and keep stirring until it blends well.
  • Empty the rhubarb mixture into the pie-crust pan. Sprinkle butter pieces.
  • Let it bake for 45 to 55 minutes, until set or golden-brown.
  • Remove the pie pan and let it cool on a rack completely before cutting it into slices.
  • Serve quickly with a huge dollop of fresh whipped cream or a readymade whipped frosting.

  • A rhubarb custard pie can be made with a store-bought gluten-free pie crust. You can use cornstarch (tapioca or potato starch) instead of all-purpose flour.
  • To save time, you can use a store-bought pie crust for the base. 
  • As a non-dairy alternative, you can use canned coconut milk instead of heavy cream.
  • You can use either light or dark-brown sugar, or even coconut sugar if you refrain from using granulated sugar. 
  • You can also make a different variation, such as a strawberry rhubarb custard pie.


  • How do you know when a custard pie is done?

If you observe the firm edges and the custard is jiggly when you shake the pan, then the pie is ready to serve.
