Step‑by‑Step Instructions for Raspberry Crumble Bars

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your oven is hot and ready for baking, providing the perfect environment for achieving that golden crust on your Gluten-Free Raspberry Crumble Bars. While the oven is warming up, gather all your ingredients and equipment, including an 8-inch square baking pan.

Step 2: Prep Pan
Line the 8-inch square baking pan with parchment paper, allowing some overhang for easy removal later. This step prevents sticking and helps achieve a beautifully shaped bar. Make sure the parchment covers the bottom and sides well, as this will make transferring the Raspberry Crumble Bars a breeze once they’re baked.

Step 3: Make Cookie Base
In a mixing bowl, combine gluten-free all-purpose flour, cane sugar, and salt. Mix them thoroughly before gradually adding the dairy-free butter, using a fork or your hands to blend until the dough forms a crumbly texture. Reserve one-third of the dough for the crumble topping to ensure a delicious layered effect in your bars.

Step 4: Bake Base
Evenly press the remaining dough into the lined baking pan, creating a solid base. Bake in the preheated oven for 14–16 minutes, or until the edges start to turn slightly golden. The aroma wafting from the oven will be enticing! Keep an eye on it to achieve that perfect slight browning, setting the stage for the other layers.

Step 5: Prepare Raspberry Filling
In a medium bowl, mash together the raspberry preserves, fresh raspberries, and a drizzle of fresh lemon juice until well combined. This filling should be fruity and slightly chunky, bursting with tangy flavor. Make sure to mix it thoroughly so each bite of the Raspberry Crumble Bars will be filled with that delightful raspberry goodness.

Step 6: Make Crumble Topping
In a separate bowl, combine the reserved dough with brown sugar, chopped pecans, and gluten-free rolled oats. Use your fingers to mix until the mixture becomes crumbly, with pea-sized clumps forming. The topping should have a nice texture that will bake to a crunchy finish, enhancing the overall experience of these Raspberry Crumble Bars.

Step 7: Assemble Bars
Once the base has finished baking, remove it from the oven and pour the raspberry filling over the top, spreading it evenly. Sprinkle the crumble topping generously over the filling, ensuring all the raspberry goodness is covered. Return the pan to the oven and bake for an additional 22–25 minutes until the topping is golden and the filling is bubbly.

Step 8: Cool and Serve
After baking, allow the Raspberry Crumble Bars to cool completely in the pan. This will help them set properly. Once cooled, use the parchment overhang to lift them out of the pan and cut into squares. A perfect balance of softness and crunch awaits you in every bite of these delightful bars!
