Rhubarb Dream Cake Recipe

It’s rhubarb season which means I’m baking up all the rhubarb recipes I’ve flagged in my vintage cook books throughout the entire year.  I’ve got my trusty regulars that I make every year including Grandma’s Rhubarb Pie, Rhubarb Streusel, Rhubarb Coffee Cake and Strawberry Rhubarb Jello Jam, but I love to try new recipes too.

This year, I’ve added Rhubarb Cobbler, Rhubarb Crumble, Sour Cream Rhubarb Cake and now these amazing Rhubarb Custard Bars that I found in my Pot O’Gold Cook Book.

Let me try to explain what makes this rhubarb custard dessert so dreamy.  I think it might be the combination of three distinct layers.

Moist Rhubarb Cake Recipe

Rhubarb Dream Cake Layers:

  1. Shortbread Crust
  2. Rhubarb Custard
  3. Cool Whip Topping

I dropped off half of a pan to my sister’s house. Her husband is a rhubarb-loving fella making him one of my top taste-testers for all things rhubarb.  Turns out, my sister loved this rhubarb dream dessert as much as he did.  She claims it’s the shortbread crust that makes them so delicious.

Rhubarb Dream Cake equals a buttery shortbread crust, sweet and soft rhubarb custard topped off with a cool layer of whipped topping.
