Gluten-Free Lemon Blueberry Bars Ingredients
For the Crust
- Butter – Provides richness and moisture; substitute with dairy-free/vegan butter for a non-dairy version.
- Sugar – Adds sweetness; organic cane sugar, coconut sugar, or monkfruit can make healthier alternatives.
- Flour – The base for your crust; Cloud9 gluten-free all-purpose flour is ideal, or use regular flour for traditional versions.
- Cornstarch – Thickens your blueberry layer; opt for arrowroot powder as a great alternative.
For the Blueberry Filling
- Blueberries – The star component; fresh or frozen blueberries work beautifully.
- Lemon – Provides fresh zest and juice; fresh lemons elevate flavor, but bottled juice is a suitable substitute.

Step‑by‑Step Instructions for Gluten-Free Lemon Blueberry Bars
Step 1: Prepare the Crust
Begin by preheating your oven to 350°F (175°C) and lining an 8×8-inch baking pan with parchment paper for easy removal. In a mixing bowl, cream together 1/2 cup of butter and 1/2 cup of sugar until light and fluffy, which takes about 3 minutes. Gradually add 1 1/2 cups of gluten-free flour and 2 tablespoons of cornstarch until the mixture resembles a crumbly dough.
Step 2: Bake the Base
Transfer the crust mixture into the prepared pan, pressing it evenly across the bottom using your hands or a spatula. Pre-bake the crust for 15-20 minutes, until it turns slightly golden around the edges. Once baked, remove from the oven and set aside to cool slightly while you prepare the blueberry filling.
Step 3: Make the Blueberry Filling
In a medium saucepan, combine 2 cups of fresh or frozen blueberries, the zest and juice of 1 large lemon, 1/4 cup of sugar, and 1 tablespoon of cornstarch. Cook over medium heat for about 5-7 minutes, stirring gently until the blueberries start to burst and the mixture thickens slightly, becoming bubbly and vibrant.
Step 4: Assemble the Bars
Once the filling is ready, pour it over the pre-baked crust, spreading it evenly with a spatula. Then, crumble the remaining crust mixture on top of the blueberries to create a streusel-like layer. This will add a lovely texture to your Gluten-Free Lemon Blueberry Bars.
Step 5: Final Bake
Return the assembled dessert to the oven and bake for an additional 25-30 minutes, or until the top is golden brown and the filling is bubbling slightly. You’ll know it’s ready when the edges start pulling away from the sides of the pan.
Step 6: Cool and Slice
Allow your bars to cool completely in the pan for at least 1 hour. For quicker cooling, place them in the refrigerator for about 30 minutes. Once cooled, lift the bars out using the parchment paper and slice into squares for clean cuts. Best served chilled!
