Summer time has me craving all of the fruity desserts. I absolutely love making desserts, especially when they are as easy as this one. This blueberry crumble is bursting with fresh berries and topped with a simple oat flour crumble.
This recipe was inspired by an old family recipe for apple crisp. It required a few adaptations to make it suitable for blueberries, such as adding a bit of lemon juice/zest to complement the berry flavor. In addition, I also reduced the sugar content quite a bit and exchanged the sugar in the filling for maple syrup.
For this recipe, I chose to use blueberries because, apart from being one of my favorite fruits, they don’t require any peeling or chopping. All you have to do is measure them out and place them in the pan. So quick!
Aside from blueberries, the filling consists of maple syrup, cornstarch or arrowroot starch, lemon zest, lemon juice, cinnamon, and salt. No need to dirty an extra bowl to mix these together. Simply place them together in the baking dish and gently stir to combine.
Up next is the crumble topping. Oat flour, vegan butter, brown sugar, and salt are combined to make the topping. I decided to go with oat flour to make this dessert gluten-free. If you don’t have any brown sugar on hand (which I never do), you can make your own by mixing together 1 tablespoon of molasses with ½ cup of sugar. I also tried making this with coconut oil instead of the vegan butter. It worked using the same ratio, however the flavor was not as good in my opinion, so I decided to stick with the vegan butter (I use Earth Balance).
I highly recommend serving with a scoop or two of non-dairy vanilla ice cream or a spoonful of the coconut whipped cream from my berry trifle recipe. Also, sometimes I like to sprinkle a little bit of flavored salt on top. I ordered a sampler kit from Saltopia a while ago that contains tons of infused salts, and I really love putting some of the blueberry or vanilla bean flavored salt on this crumble.
