Bake up this easy, old fashioned rhubarb custard pie for the most amazing springtime dessert.

This decadent dessert is rich, creamy, and tart and yet incredibly easy to pull together for a pie that is sure to delight and make use of that ever abundant rhubarb.

Simple Ingredients

One of the best things about this pie is that it is so very basic. Once rhubarb is in season, the rest of the ingredients are likely already in your pantry.

And yet it is because of that simplicity that this pie is so very good.

Tart or Sweet?

You can adjust the sugar up or down depending on your rhubarb and desired tartness level.

Go down to 1 cup for a much more tart but still delicious and sweet enough pie.

Go up to 1 1/2 cups or even more sugar for something much sweeter and less tart.


Make it Richer

Use heavy cream or half-and-half instead of milk for an even richer custard. I tend to use whatever milk is in the fridge and don’t worry about running to the store to get heavy cream.

Pie Crust Options

Use your favorite recipe here, no need to make something special. If you don’t have a favorite, here’s an easy pie crust recipe for you to try.

You could bake it up without a top crust if desired. Just bake until the custard is set.

A lattice top crust would also work delightfully instead of the full crust as pictured.

How to Serve

Do let the pie cool about an hour at room temperature before slicing. It doesn’t have to be cold but you don’t want it to be steaming hot either.

Top slices with ice cream or whipped cream as desired. Though it is quite good plain, too.

Yield: 8 slices
