Ingredients You Need for Homemade Lemon Rhubarb Bars

For the crust:

• 1 cup all-purpose flour
• 1/4 cup powdered sugar
• 1/2 cup unsalted butter (cold and cubed)
• 1/4 teaspoon salt

For the filling:

• 1 cup chopped fresh rhubarb
• 2 large eggs
• 3/4 cup granulated sugar
• 2 tablespoons all-purpose flour
• 1/4 cup fresh lemon juice
• 1 tablespoon lemon zest
• 1/2 teaspoon vanilla extract

For topping:

• Powdered sugar for dusting

Step-by-Step Guide

1. Prepare the baking pan

Start by preheating your oven to 350°F or 175°C. Line your baking pan with parchment paper for easy removal. Leave some paper hanging on the sides. This helps lift the bars out later without breaking them. Lightly grease the paper for extra safety.

2. Make the buttery crust

In a bowl, mix flour, powdered sugar and salt. Add cold butter cubes and rub with fingers. Keep mixing until it looks like soft crumbs. Press this mixture firmly into the pan base. Bake for 15 minutes until slightly golden and set.

3. Prepare the rhubarb filling

Wash and chop rhubarb into small pieces. Set aside in a bowl. In another bowl, whisk eggs and sugar until smooth. Add flour, lemon juice, lemon zest and vanilla extract. Mix gently until everything becomes creamy and well combined.

4. Add rhubarb into filling

Now fold chopped rhubarb into the lemon mixture. Stir slowly so rhubarb spreads evenly. The filling should look slightly thick and creamy. This step is important because it ensures every bite has balanced sweet and tart flavors throughout the bars.

5. Pour and bake the bars

Pour the filling over the warm crust. Spread it evenly with a spatula. Place the pan back into the oven. Bake for 25 to 30 minutes until the center is set. The top should look lightly golden and slightly firm when touched.

6. Cool and slice carefully

Remove the pan from the oven and let it cool completely. This step is very important for clean slices. Once cooled, lift the bars using parchment paper. Cut into squares or rectangles. Dust with powdered sugar for a soft finishing touch before serving.
