Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 375°F (190°C). Line a 9-inch square baking pan with parchment paper, leaving an overhang on the sides. This will make it easy to lift the bars out later.
- Make the Crumb Mixture: In a large bowl, whisk together the gluten-free all-purpose flour, granulated sugar, packed light brown sugar, baking powder, and salt.
- Cut in the Butter: Add the cold, cubed butter to the dry ingredients. Use a pastry blender, your fingertips, or a food processor to cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces of butter remaining. This is crucial for that signature crumbly texture.
- Form the Base: Take about two-thirds of the crumb mixture and press it evenly into the bottom of the prepared baking pan to form the base layer.
- Prepare the Blueberry Filling: In a separate medium bowl, gently toss together the blueberries, granulated sugar, cornstarch (or tapioca starch), lemon juice, lemon zest (if using), and cinnamon (if using). Ensure the blueberries are evenly coated.
- Add the Filling: Pour the blueberry filling evenly over the pressed crumb base in the baking pan.
- Top with Crumble: Sprinkle the remaining one-third of the crumb mixture evenly over the blueberry filling.
- Bake to Perfection: Place the pan in the preheated oven and bake for 35-45 minutes, or until the topping is golden brown and the blueberry filling is bubbling around the edges.
- Cool Completely: Remove the pan from the oven and let the bars cool completely on a wire rack. This is important for the bars to set properly and makes them easier to cut. For best results, allow them to cool for at least 2-3 hours, or even refrigerate them for easier slicing.
- Slice and Serve: Once completely cooled, use the parchment paper overhang to lift the entire slab out of the pan. Cut into squares or rectangles to serve.

Storing and Reheating Tips
Proper storage is key to ensuring your Sweet Gluten-Free Blueberry Crumb Bars remain delicious.
- Refrigeration: Once cooled completely, store the bars in an airtight container in the refrigerator for up to 3-4 days. This helps maintain the freshness of both the crumb and the blueberry filling.
- Freezing: For longer storage, you can freeze the cooled bars. Wrap individual bars tightly in plastic wrap, then place them in a freezer-safe bag or container. They will keep well in the freezer for up to 2-3 months.
- Reheating: If you prefer to enjoy them warm, you can reheat individual bars gently.
- Oven: Place a bar on a baking sheet and warm in a preheated oven at 300°F (150°C) for 5-10 minutes, or until heated through.
- Microwave: Alternatively, microwave a bar on medium power for 15-30 seconds, being careful not to overcook as they can become soft.
- Thawing Frozen Bars: To thaw frozen bars, transfer them from the freezer to the refrigerator overnight, or microwave them on a defrost setting until thawed. Allow them to come to room temperature or reheat as desired before serving.
