Ingredients and Preparation
Essential Ingredients and Possible Substitutions
To create the magic of Old-Fashioned Rhubarb Custard Bars, you will need some key ingredients. Here’s a breakdown:

- Eggs: Essential for the custard, giving it that silky texture.
- Milk: Whole milk is best, but you can substitute with almond or oat milk for a dairy-free option.
- Butter: Unsalted butter is ideal, but coconut oil can work if you’re aiming for a dairy-free version.

Step-by-Step Recipe Instructions with Tips
Here’s how to bake your very own Old-Fashioned Rhubarb Custard Bars:
- Prepare your rhubarb: Start by washing and chopping about 4 cups of fresh rhubarb into bite-sized pieces.
- Preheat your oven: Set it to 350°F (175°C) so it’s ready to go when your bars are assembled.
- Make the crust: In a mixing bowl, cream together 1 cup of granulated sugar and 1/2 cup of softened butter until fluffy. Add 1 egg and mix well. Gradually incorporate 1 1/2 cups of flour and a pinch of salt until dough forms. Press this mixture into the bottom of a greased 9×13-inch baking pan.
- Prepare the custard filling: In another bowl, whisk together 2 eggs, 1 cup of milk, 1 cup of sugar, and 1/4 cup of flour until smooth. Fold in the chopped rhubarb gently.
- Assemble: Pour the custard filling over the crust, spreading it evenly.
- Bake: Slide the bars into the oven and let them bake for about 45-50 minutes, or until the custard is set and the top is slightly golden.
- Cool and cut: Allow the bars to cool completely before cutting them into squares.
- Serve: Enjoy them as is or top them with whipped cream for an extra indulgence.
Whether it’s the gentle folding of the rhubarb into the custard or the anticipation as your kitchen fills with a warm, inviting aroma, remember to savor each step of the process.
