The Blueberry Crumble Dessert is a delightful treat that combines the tartness of fresh blueberries with a buttery, crunchy topping. Perfect for any occasion, the dessert will have your friends and family coming back for seconds as they savor each warm bite topped with a scoop of ice cream.

If you’re caught without fresh blueberries, frozen ones work just as well, and might even save you a trip to the store. The recipe calls for light brown sugar, but feel free to use dark brown sugar for a deeper flavor. For those watching their sugar intake, substituting a sugar alternative should work, but the taste may vary. Always check for allergies when serving, especially with butter and oats included.
