A simple apple cranberry crumble with a sweet and tart fruit filling and buttery brown sugar oat crumb topping. So easy to prepare and perfect for a crowd. Gluten free and vegan friendly.
6 Tbsp (85g) unsalted butter, melted ¹
1 cup (300g) packed brown sugar, divided
3–4 medium apples, peeled and sliced ²
2 cups (8 oz) cranberries
1 Tbsp pure vanilla extract
1 Tbsp fresh lemon juice
1–1/2 Tbsp arrowroot starch ³
3/4 cup (90g) all-purpose flour ⁴
1/2 cup (40g) rolled oats
1/2 tsp kosher salt
optional: 1/2 cup chopped nuts
Preheat the oven to 350℉. Lightly butter a 9×9-inch baking dish. Set aside.
In a medium mixing bowl, combine the fruit with 1/2 cup brown sugar. Stir in the vanilla and lemon juice, followed by the arrowroot, until evenly coated. Set aside.
In another mixing bowl, stir together the flour, oats, salt, and remaining brown sugar. Drizzle with the melted butter and stir until the mixture is crumbly and completely moistened. Stir in the nuts, if using.
Add the apple-cranberry mixture (and juices) to the prepared pan in an even layer, and top with the crumbs.
Bake for 45-55 minutes, until the fruit is tender and the topping is golden with juices bubbling up around the edges. Remove from the oven and let cool for at least 15 minutes for a saucier crisp or up to 45 mins for a more set filling. Either way is delish! Serve warm or at room-temperature.
¹ Make it vegan: substitute vegan butter such as Miyokos or Earth Balance.
² Look for a sweet, firm variety of apple such as Granny Smith or Honeycrisp.
³ Arrowroot starch is my thickener of choice for pies and fruit fillings. It’s a natural plant-based starch that creates a smooth, shiny sauce without a noticeable taste. You can also use cornstarch or tapioca flour. Make it gluten free: Use an all-purpose gluten free flour blend instead of the all-purpose flour, and be sure your oats are also certified gluten free.
⁴ Make it gluten free: Use an all-purpose gluten free flour blend instead of the all-purpose flour, and be sure your oats are also certified gluten free.
