Making Your Gluten Free Rhubarb Bars: A Step-by-Step Guide

Now for the fun part! Let’s walk through the steps of creating these delicious gluten free rhubarb bars. Remember, baking is a journey, not a race. Take your time, enjoy the process, and don’t be afraid to experiment.

Preheat and Prep: Preheat your oven to 375°F (190°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang for easy removal. This is important for preventing the bars from sticking. The parchment paper will also help you lift the bars out easily once they’re cooled.
Make the Crust: In a large bowl, combine the gluten-free oats, oat flour, brown sugar, tapioca starch, baking powder, sea salt, and cinnamon. Add the melted vegetable shortening and mix until the mixture resembles coarse crumbs. If you are using your hands, gently rub the shortening into the dry ingredients.
Press the Crust: Press about two-thirds of the crumb mixture into the prepared baking pan to form the crust. You can use the back of a spoon or your fingers to create an even layer. Make sure the crust is firmly packed. For about half the baking time, the crust will be blind-baked. This helps it crisp up and prevents it from becoming soggy. Bake the crust for about 10 minutes, or until lightly golden.
Prepare the Rhubarb Filling: While the crust is baking, prepare the rhubarb filling. In a medium bowl, combine the chopped rhubarb, raspberries, raw cane sugar, lemon zest, lemon juice, cornstarch or tapioca starch, and vanilla essence. Mix well to ensure the rhubarb and raspberries are evenly coated. The cornstarch or tapioca starch will help thicken the filling as it bakes.
Assemble and Bake: Pour the rhubarb filling over the pre-baked crust. Sprinkle the remaining crumb mixture evenly over the filling. Bake for about 30-35 minutes, or until the topping is golden brown and the filling is bubbly. The baking time may vary depending on your oven, so keep an eye on it.
Cool and Cut: Let the bars cool completely in the pan before cutting. This will allow the filling to set and prevent the bars from falling apart. Once cooled, lift the bars out of the pan using the parchment paper overhang and cut into squares. These bars are best enjoyed at room temperature or chilled.

Pro Tips for Perfect Gluten Free Rhubarb Bars

Here are a few extra tips to ensure your gluten free rhubarb bars turn out perfectly every time:

Use High-Quality Ingredients: The better the ingredients, the better the bars will taste. Choose fresh, ripe rhubarb and raspberries for the best flavor.
Don’t Overmix the Crust: Overmixing can result in a tough crust. Mix until just combined.
Adjust Sweetness to Taste: If you prefer a sweeter bar, add a little more sugar to the filling. If you like it tart, reduce the sugar slightly.
Use Frozen Fruit: If you’re using frozen rhubarb or raspberries, there’s no need to thaw them first. Just add them directly to the filling.
Let Them Cool Completely: This is crucial for preventing the bars from falling apart. Be patient and let them cool completely before cutting.

Common Mistakes to Avoid

Even the simplest recipes can have a few pitfalls. Here are some common mistakes to avoid when making these gluten free rhubarb bars:

Not Measuring Ingredients Accurately: Baking is a science, so accurate measurements are essential. Use measuring cups and spoons, and level them off carefully.
Overbaking the Bars: Overbaking can result in a dry, tough crust. Keep an eye on the bars and remove them from the oven when the topping is golden brown and the filling is bubbly.
Cutting the Bars Too Soon: Cutting the bars while they’re still warm can cause them to fall apart. Let them cool completely before cutting.
Skipping the Parchment Paper: Parchment paper makes it much easier to remove the bars from the pan. Don’t skip this step!

Variations to Try

Want to add your own personal touch to these gluten free rhubarb bars? Here are a few variations to try:

Strawberry Rhubarb Bars: Replace half of the raspberries with sliced strawberries for a classic combination.
Ginger Rhubarb Bars: Add 1 teaspoon of ground ginger to the crust mixture for a warm, spicy twist.
Almond Rhubarb Bars: Add 1/4 cup of sliced almonds to the topping for added crunch and flavor.
Lemon Rhubarb Bars: Increase the lemon zest to 1 tablespoon for an extra burst of citrus flavor.

Storing Your Gluten Free Rhubarb Bars

These gluten free rhubarb bars are best enjoyed fresh, but they can also be stored for later. Here’s how:

Room Temperature: Store the bars in an airtight container at room temperature for up to 2 days.
Refrigerator: Store the bars in an airtight container in the refrigerator for up to 5 days.
Freezer: For longer storage, wrap the bars individually in plastic wrap and store them in a freezer-safe bag or container for up to 2 months. Let them thaw completely before serving.

Frequently Asked Questions (FAQ)

My crust is too crumbly. What did I do wrong? The crust may be too crumbly if you added too much dry ingredients or not enough melted shortening. Make sure to measure accurately and adjust as needed.
