Originating in China over 2,000 years ago, rhubarb made its way to Europe in the 16th century, where it flourished in home gardens and began finding its way into sweet and savory dishes alike.

Growing up, I often enjoyed making these bars with my grandmother. She would tell me stories of how her grandmother made them during the harvest season, using fresh rhubarb from her garden.

Required Equipment & Tools

To prepare your Rhubarb Custard Bars, you’ll need:

• Mixing Bowls: For combining the crust and custard.
• 9×13 Inch Baking Pan: The perfect size for these bars.
• Parchment Paper: To line the pan for easy removal.
• Whisk: Useful for beating the eggs and mixing the custard.

Nice-to-Have Tools

Foolproof Step-by-Step Instructions

Step 1: Prep Your Ingredients (5 minutes)

Gather all the ingredients and ensure your rhubarb is prepped by chopping it into small pieces.

Step 2: Make the Crust (15-20 minutes)

1. Preheat your oven to 350°F (175°C).
2. Combine the 1 1/2 cups of flour and 1/2 cup of powdered sugar in a mixing bowl.
3. Add the cold, cubed butter, mixing until crumbly (you can use a pastry cutter or your fingers).
4. Press the mixture into the bottom of a lined baking pan.
5. Bake for 15-20 minutes until lightly golden. Cool slightly.

Step 3: Prepare the Filling (15 minutes)

1. Spread the rhubarb evenly over the cooled crust.
2. In a separate bowl, whisk together the 1 1/2 cups of granulated sugar, 1/4 cup all-purpose flour, eggs, salt, and vanilla extract.
3. Pour the custard mixture over the rhubarb.

Step 4: Bake the Bars (35-40 minutes)

1. Bake for 35-40 minutes, or until the custard is set and the edges are golden.
2. Allow to cool completely in the pan on a wire rack.

Step 5: Serve with Style

1. Lift the bars from the pan using the parchment paper. Cut into squares and serve!
2. Optional: Dust with powdered sugar or serve with whipped cream for an extra treat.

Pro Tip: To ensure perfect edges, avoid cutting until the bars are completely cooled.

Professional Chef Secrets

1. Temperature Control: Let your butter sit out for a bit before using—this helps you achieve that perfect crumble in your crust.
2. Eggs at Room Temperature: This tip ensures that they blend better with the rest of your custard mixture, leading to a smoother texture.
3. Cool Before Cutting: Allowing bars to cool entirely prevents the filling from running when cut.
4. Rhubarb Preparation: Rinse and dry rhubarb well to reduce excess moisture, which can make the filling watery.
5. Baking Dish Alternatives: If you don’t have a 9×13 pan, two smaller pans work just as well.

Creative Variations & Adaptations

Seasonal Variations

• In summer, try using peaches for a fresh twist.
• In autumn, substitute ripe apples for a cozy flavor.

Dietary Modifications

• Vegan: Use flax eggs in place of regular eggs and coconut oil instead of butter.
• Keto-friendly: Swap sugars for your preferred low-carb sweetener and use almond flour for the crust.
