Easy Rhubarb Berry Sourdough Discard Crumble

Summer Sourdough Discard Rhubarb Berry Crumble

It’s rhubarb season, and this easy sourdough discard rhubarb crumble is one of our favorite summer desserts! This recipe has a sweet, buttery crumble topping made with sourdough discard and a gooey fruit filling that can be made with rhubarb, plums, berries, peaches, apples, or any mix of fruit you love. The best part? You don’t need active, bubbly starter for this recipe. Cold sourdough discard works beautifully in the crumble topping and gives it the most delicious texture.

Come bake with me, we’ll make the crumble topping, prep the rhubarb and fruit filling, mix in that cornstarch and bake it to a perfect bubbly crumble topping.

Rhubarb Sourdough Crumble Recipe:

Topping:

200 g (1 1/4 cups) all purpose flour

160 g (2/3 cup) brown sugar

90 g (6 Tb) granulated white sugar

6 g (2 tsp) cinnamon

2 g (1/4 tsp) salt or 16 cracks

113 g (1/2 cup) room temperature salted butter

130 g (1/2 cup) cold discard

Filling:

1100-1200 g (8 cups) rhubarb, berry mix

160 g (3/4 cup) granulated white sugar

36 g (3 Tb) corn starch

1.5 g (1/8 tsp) salt or 10 cracks

Instructions:

Preheat oven to 375 degrees. Coat a 9×13 baking dish with nonstick cooking spray.

In a large bowl, mix the sugar, cornstarch and salt, then gently toss the strawberries and rhubarb until coated. Pour into your prepared baking dish.

In a separate medium sized bowl, mix the flour, brown sugar, granulated sugar, cinnamon, and salt. Use a pastry blender to work the butter and sourdough discard in until the mixture is sticking together in coarse crumbles. Sprinkle the topping over the rhubarb mixture.

Bake for 50 minutes or until the topping is browned in the middle and the sauce from the rhubarb mixture is bubbling.

Let cool until the filling is no longer bubbling and it has set a bit. The longer it rests the thicker the filling will get. Top with whipping cream or ice cream and enjoy.

It's true, years ago we decided to use our everyday life as a way to fight against slavery and trafficking. Since then we started hosting the Freedom Dinners and when our business started, we knew we wanted it to give back too. We donate 10% of all of our profits to AtlasFree⁩ to fight for those that cannot stand up for themselves.
