Easy Rhubarb Custard Bars

A shortbread crust, a layer of rhubarb and rich custard, finished with a thick, whipped, cheesecake-like topping, and these easy Rhubarb Custard Bars do not disappoint.

I have so much rhubarb coming out of my garden this spring, I’ve been searching for new ways to use it! I’ve baked up all my favorite rhubarb dessert classics, plus experimented with a few rhubarb cocktails too! These Easy Rhubarb Custard Bars are near the top of the list for my favorites so far.

How to Make Easy Rhubarb Custard Bars

Rhubarb Custard Bars start with a simple 3-ingredient shortbread base: flour, sugar, and butter. Combine it using a pastry cutter or food processor and then press into the bottom of a greased 9×13 baking pan. I use the bottom of a mixing cup to give it a firm, even press.

Bake the crust for 10 minutes at 350 degrees.

Fresh or Frozen Rhubarb?

Either one works great for these Rhubarb Custard Bars. If you do use frozen, just be sure to thaw and drain well. Scatter the rhubarb evenly across the top of the pre-baked crust.

Make the custard mixture by beating together eggs, cream, sugar and a little bit more flour to thicken it. Pour this over the rhubarb and shortbread crust.

Bake until the custard is set in the middle–about 45-50 minutes. Cool. It will be hard to wait at this point, because your whole house will smell so good, but hold yourself back please. The final topping is made from sugar, cream cheese and whipped cream, and you don’t want to spread it on an overly warm custard or sad things will happen.

Once the bars have cooled to room temperature, you can spread the thick, cheesecake-like frosting over the whole thing. Then pop it into the fridge to chill for at least 30 minutesl. These bars are best served cold.

The buttery shortbread, rich custard and decadent whipped topping layer make this a surefire crowd-pleaser. It’s an excellent choice for potlucks or family gatherings. You can easily cut the recipe in half and bake in a square baking dish to serve a smaller group, too.
