How to Make Tangy Lemon Rhubarb Bars (Step-by-Step)
Step 1: Prepare the Rhubarb
Wash and chop the rhubarb into small, even pieces. This helps it cook evenly and blend smoothly into the filling.
Step 2: Make the Crust
In a bowl, combine the flour, butter, and a portion of the sugar until the mixture forms a crumbly dough. Press it evenly into a lined baking pan to create the base layer.
Step 3: Pre-Bake the Base
Bake the crust in a preheated oven at 350°F (175°C) for about 12–15 minutes, or until it is lightly golden and set.
Step 4: Prepare the Filling
In another bowl, whisk together the eggs, remaining sugar, lemon juice, lemon zest, vanilla extract, and salt until smooth.
Step 5: Add the Rhubarb
Fold the chopped rhubarb into the lemon mixture, ensuring it is evenly distributed.
Step 6: Assemble and Bake
Pour the filling over the pre-baked crust and return the pan to the oven. Bake for 25–30 minutes, or until the center is set and no longer jiggly.
Step 7: Cool and Slice
Allow the bars to cool completely before slicing. This helps them firm up and makes clean cuts easier.
Tips & Variations
- Make it sweeter: Add a handful of chopped strawberries to balance the tartness of rhubarb.
- Extra citrus boost: Add a bit more lemon zest for a stronger zing.
- Gluten-free option: Use a 1:1 gluten-free flour blend for similar results.
- Dairy-free swap: Replace butter with a plant-based alternative.
- Dust with sugar: A light sprinkle of powdered sugar on top adds a pretty finish.
Serving Ideas & Storage
Serve these lemon rhubarb bars chilled or at room temperature. They pair wonderfully with a cup of tea or a refreshing glass of lemonade.
For storage, keep them in an airtight container in the refrigerator for up to 4 days. You can also freeze them for longer storage—just thaw in the fridge before serving.
