A nostalgic dessert from the Great Depression era, water pie transforms simple pantry staples into a surprisingly creamy, custard-like treat with a delicate vanilla flavor and crisp, sugary crust.

I first learned about water pie from my grandmother, who often made it when ingredients were scarce but comfort was needed at the table.

Ingredients

  • Unbaked 9-inch pie crust: Store-bought or homemade
  • Water: 1 1/2 cups
  • Unsalted butter: 4 tablespoons
  • Granulated sugar: 3/4 cup
  • All-purpose flour: 3 tablespoons
  • Vanilla extract: 1 teaspoon
  • Salt: Pinch

Instructions

Prepare oven:
Preheat your oven to 400°F (200°C).
Shape crust:
Place the unbaked pie crust into a 9-inch pie pan, crimping the edges as desired.
Add water:
Pour the water directly into the pie crust.
Mix dry ingredients:
In a small bowl, mix together the sugar and flour until thoroughly combined. Sprinkle this mixture evenly over the water in the crust.
Add flavor:
Drizzle the vanilla extract over the top and add a pinch of salt.
Distribute butter:
Slice the butter into thin pats and distribute them evenly over the surface.
Bake:
Carefully transfer the pie to the lower rack of the oven. Bake for 30 minutes at 400°F (200°C).
Finish baking:
Reduce oven temperature to 375°F (190°C) and bake for an additional 20 minutes, until the crust is golden and the filling is set with a slight jiggle in the center.
Cool:
Remove from the oven and allow to cool completely to room temperature. Refrigerate for at least 2 hours before slicing for best texture.
