Water Pie: The Great Depression Dessert Made From Almost Nothing

During the Great Depression, families made pie out of almost nothing. No fruit, no eggs, no cream. Just water, a little flour and sugar, and a few dots of butter.

It sounds like a joke. It is not. As it bakes and cools, that thin watery filling sets into a soft, sweet custard that tastes like a vanilla pudding pie.

I made one expecting sweetened dishwater. What came out of the oven was a genuinely good pie, and it cost pennies.

The Story of Water Pie

Water pie belongs to a whole family of “desperation” desserts that came out of the 1930s. When the pantry was bare, cooks reached for what was left: flour, sugar, and whatever fat they had.

The same hard years gave us vinegar pie, mock apple pie made from crackers, and sugar cream pie. Each one turned a nearly empty kitchen into something sweet for the table.

What makes water pie remarkable is how little it asks for. There is no fruit to buy, no eggs to spare, and no milk to pour. The water does the work that a custard base normally would.

Why Water Pie Actually Works

The trick is the flour and sugar. As the pie bakes, the flour thickens the water while the sugar dissolves into a syrup.

The butter melts through it and the vanilla flavors the whole thing. When the pie cools, that mixture firms up into a wobbly custard, soft in the center and just set at the edges.

It will look alarmingly liquid when it comes out of the oven. Do not panic and do not slice it. The magic happens entirely during cooling.

Ingredients

• 1 unbaked 9-inch pie crust
• 1 1/2 cups water
• 1 cup granulated sugar
• 4 tablespoons all-purpose flour
• 5 tablespoons butter, cut into small pieces (margarine works too)
• 1 1/2 teaspoons vanilla extract

Instructions

Step 1: Prepare the Crust

Preheat the oven to 400°F (200°C). Fit the unbaked pie crust into a 9-inch pie dish (this OXO ceramic dish is my reach-for) and crimp the edges. Set it on a baking sheet (Nordic Ware aluminum is the only one that does not warp), because the filling starts out very liquid and can slosh.

Step 2: Add the Water

Pour the water straight into the crust. Yes, plain water. This is the whole secret of the pie.

Step 3: Add the Sugar and Flour

Stir the sugar and flour together in a small bowl, then sprinkle the mixture evenly over the water. Do not stir it into the water. Let it settle on the surface on its own.

Step 4: Dot With Butter and Vanilla

Scatter the pieces of butter across the top, spacing them out. Drizzle the vanilla over everything. The filling will look like a strange puddle, and that is exactly right.

Step 5: Bake

Bake at 400°F for 30 minutes, then lower the heat to 375°F (190°C) and bake for another 30 minutes. The top should be golden and the filling will still wobble like water.

Step 6: Cool Completely

This is the step that matters most. Cool the pie fully at room temperature, then chill it for a few hours or overnight. It sets into a soft custard as it cools. Slice it too soon and you get soup.

Tips for a Better Water Pie

• Patience is the ingredient. An overnight chill gives the cleanest slices. A warm pie will never firm up.
• Do not stir the filling. The layers set better when the sugar and flour float on top rather than being mixed in.
• Use a baking sheet underneath. The liquid filling can bubble over, and it is far easier to clean a tray than the oven floor.
• Add a little nutmeg or cinnamon if you want it closer to an old-fashioned custard pie.

Water Pie FAQ

What is water pie?

Water pie is a Great Depression dessert made from water, flour, sugar, butter, and vanilla baked in a pie crust. As it cools, the filling sets into a soft, sweet custard.

Does water pie actually taste good?

Surprisingly, yes. It tastes like a light vanilla custard or sugar-cream pie. It is simple and mild, not rich, which is exactly why Depression families loved it.

Why is it called water pie?

Because water is the main ingredient in the filling. When milk, eggs, and fruit were too expensive, water stood in for the custard base and still produced a pie worth eating.

Can I make water pie with margarine?

Yes. Margarine was the common choice during the Depression because butter was a luxury. Either one works, and the pie sets the same way.

Water pie is one of the most extreme examples of Depression baking, but it is far from the only one. For more of the same clever, penny-pinching spirit, browse our full collection of Great Depression recipes, or try its close cousin, the eggless Great Depression cake.
