How To Make Rhubarb Custard Bars
Making these rhubarb custard bars is simple; if you don’t have a food processor, use a mixing bowl.
The ingredients will come together nicely for the base if you mix them with a wooden spoon.
I used the bright red juice from my pickled beets to colour the rhubarb as the natural colour fades whenever baked.
I added a few tablespoons of the juice to a bowl and mixed it with the sliced rhubarb.
Any excess juice in the bowl was discarded as I didn’t want it added to the custard.
You do not have to do this step as it is purely for aesthetic reasons.
Easy Rhubarb Custard Bars
The base is similar to a butter cookie or shortbread, and I could eat it alone; it’s good.
Once the base is in the oven baking for 12 minutes, I prepare the custard filling mixture.
You don’t have to wait until the base is cooled before pouring the creamy custard layer.
Pull the base from the oven, and evenly pour the egg custard mixture over the top.
I sprinkled unsweetened coconut and sliced almonds on top, but that’s optional.
You can leave it as is or add any topping you’d like.
Put the rhubarb custard bars back in the oven to bake until golden, 45 minutes.
We had to go to a picnic so it was easy to transport this way and I could leave it there.
Once we arrived, I cut the bars, but you can also cut them ahead of time.
Cover with tin foil only after the rhubarb custard bars are cooled, then refrigerate, freeze, or transport them.
