This delightful anytime recipe is "crunchy" in two ways: it has a crispy oat topping, and it's the perfect way to use up any fruit—fresh or frozen—before it goes to waste. Whole grain oats are mixed with our premium Unbleached White All-Purpose Flour, butter and sugar to create a top with the perfect texture. We used a mixture of peaches, plums and blueberries, but apples, pears and berries also work well. Serve this whole grain treat with a scoop of ice cream!
Using either a stand mixer with the paddle attachment or your fingers, work the butter into the dry ingredients until there are no dry dusty bits and a chunky streusel forms.
Break up any large pieces and place topping in the fridge while you make the fruit filling.
Alternatively, you can make the crumble up to one month in advance and store it in the freezer. You can use it right out of the freezer, just follow the baking instructions as follows.
Make the Fruit Filling
Preheat oven to 375°F. Lightly butter or grease a 2-quart baking dish (such as a 9 x 13-inch dish).
Add prepared fruit to a large bowl. Mix together cornstarch, sugar and nutmeg and evenly sprinkle it over the fruit.
Zest lemon directly into the bowl and add vanilla extract and a pinch of salt. Using a spoon or spatula, mix thoroughly so that there are no dry pockets of cornstarch.
To Assemble
Add the fruit filling to the baking dish and spread it out. Sprinkle crumble topping in an even layer over the top.
Place on a baking sheet. This will make getting it out of the oven easier and catch any potential juices that could bubble over.
Bake for 40–50 minutes, or until the crumble is nicely browned and the fruit filling is bubbling
Let cool slightly and serve warm with ice cream! Cover and store leftovers in the fridge for up to 3 days.
