Ingredients
Topping
- 3 cups gluten free flour (360 grams)
- 1 teaspoon baking powder
- ¼ teaspoon fine sea salt
- ⅓ cup granulated sugar
- ⅓ cup brown sugar
- 1 lemon , zested
- ½ cup unsalted butter , melted
Filling
- 5 cups chopped rhubarb , trimmed and chopped into ½-inch pieces
- 1 tablespoon fresh lemon juice
- 1 cup granulated sugar
- ⅓ cup arrowroot , or cornstarch
Instructions
- Preheat the oven to 375℉ and have a 9x13-inch pan ready.
- Make topping: In a medium bowl, whisk together the oat flour, baking powder, salt, granulated sugar, brown sugar, and lemon zest. Add the melted butter and stir until the mixture forms pea-size and slightly larger clumps. Refrigerate while making the filling.
- Make filling: In a large bowl, combine the rhubarb, strawberries, lemon juice, sugar, arrowroot, and salt. Let it stand for 15 minutes.
- Spread the fruit filling evenly in the pan. Take the topping out of the fridge, crumbling it up if it's hard, and spread it evenly over the fruit filling.
- Place in the oven and bake for 45-50 minutes until the fruit is bubbling and the topping is a light golden brown.
- Remove from the oven and let rest for at least 15 minutes to solidify the filling before serving.
Notes
- Chill the topping - Even 15 minutes in the fridge will help the gluten-free flour to hydrate and the butter to firm, which will make the topping even more tender and buttery after it's baked.
- Make topping in advance - Also consider making the topping in advance and freezing it in an airtight container for up to 2 months. Thaw the topping in the fridge before using.
- Other fruit - Use the topping recipe and general method with any kind of summer fruit you like, from cherries, to peaches, to plums.
- Add vanilla - Stir in 1-2 teaspoons of pure vanilla extract or vanilla bean paste to the filling.
- Make it dairy-free - Use melted coconut oil or non-dairy butter instead of the butter.
- Serving options: With vanilla ice cream, lightly sweetened whipped cream, or a drizzle of caramel sauce!
