Ingredients

For the Crust:
- 1 3/4 cups all-purpose gluten-free flour blend (I used Better Batter)
- 1 teaspoon xanthan gum (omit if your blend already contains it)
- 1/4 cup cornstarch
- 3/4 cup granulated sugar
- 1/4 teaspoon kosher salt
- 12 tablespoons unsalted butter (at room temperature)
- 1 egg yolk (at room temperature)
For the Topping:
- 1/4 cup all-purpose gluten-free flour blend (I used Better Batter)
- 1/8 teaspoon xanthan gum (omit if your blend already contains it)
- 1/2 cup packed light brown sugar
- 1 teaspoon ground cinnamon
- 3 tablespoons unsalted butter (melted and cooled)
- 2 teaspoons pure vanilla extract
For the Filling:
- 8 ounces rhubarb stalks (cleaned and roughly chopped)
- 8 ounces fresh strawberries (cleaned, hulled, and roughly chopped)

Step-by-Step Instructions

Preheat your oven to 350°F. Line an 8-inch square pan with crisscrossed sheets of unbleached parchment paper, each overhanging two opposite sides. Set the pan aside.
Make the Crust. In a large bowl, whisk together the gluten-free flour, xanthan gum (if using), cornstarch, granulated sugar, and kosher salt. Add the softened butter and egg yolk. Mix until the dough holds together and is crumbly but slightly sticky. Press the mixture into the bottom of the prepared pan evenly.
Make the Topping. In another bowl, combine the gluten-free flour, xanthan gum (if using), light brown sugar, and cinnamon. Stir in the melted butter and vanilla extract until mixed but still crumbly.
Assemble the Bars. In a mixing bowl, toss the chopped rhubarb and strawberries together. Spread the rhubarb-strawberry mixture evenly over the crust. Top with the crumble topping, spreading it as evenly as possible.
Bake and Serve the Bars. Bake in the preheated oven for 30-35 minutes or until the topping is golden brown and the filling is bubbling. Allow the bars to cool in the pan. Remove them using the overhanging parchment paper and cut them into squares for serving.

How to Serve Gluten Free Rhubarb Crisp Bars

For an extra touch of indulgence, serve them with a scoop of vanilla ice cream or a dollop of whipped cream. Don’t forget to pair them with your favorite herbal tea or a refreshing drink to complement the tartness of the rhubarb and strawberries.

How to Store Gluten Free Rhubarb Crisp Bars

To keep your Gluten Free Rhubarb Crisp Bars fresh, store them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate the bars for up to a week. For longer storage, these bars freeze well. Wrap them tightly in plastic wrap and place them in a freezer-safe container for up to 3 months. When ready to enjoy, thaw at room temperature or reheat in a microwave for a warm treat.

Tips to Make Gluten Free Rhubarb Crisp Bars Perfect

Choose Fresh Ingredients. Use fresh rhubarb and strawberries for the best flavor. If rhubarb is not in season, frozen rhubarb can also work but may need extra cooking time to remove excess moisture.
Measure Correctly. When using gluten-free flour, be sure to measure by weight for more accurate results, as gluten-free flours can vary in density.
Let Cool Before Cutting. Allow the bars to cool completely in the pan before slicing. This helps the filling set and makes it easier to cut clean bars.

Flavor Variations

Get creative with your Gluten Free Rhubarb Crisp Bars by trying different fillings or toppings:

Berry Medley: Mix in blueberries or raspberries for a berry medley twist.
Coconut Crisp: Add unsweetened shredded coconut to the topping for added texture and flavor.
Nuts: Incorporate chopped nuts, such as walnuts or almonds, into the topping for a nutty crunch.

Pro Tips for Success

Room Temperature Ingredients: Ensure butter and egg yolk are at room temperature for easy mixing.
Chill the Dough: If the dough is too soft to press into the pan, chill it for 15-30 minutes.
Bake Evenly: Rotate the pan halfway through the baking time for even browning.

FAQs About Gluten Free Rhubarb Crisp Bars
