This recipe is a keeper. And one I would categorize as a dessert. It’s sweet and delicious and utilized fresh fruit. Fresh blackberries to be exact. We have so many that grow wild out back on our property. So during peak season I make a point to go out every day and pick. They are covered in thorns and located in the brush so I have to wear long pants, boots and gloves. But it’s worth it because I put away 30+ jars of fresh black raspberry jam and made countless of these fresh black raspberry crumbles.
We prefer to bake in cast iron. You don’t have to, you could use a regular baking dish. But cast iron is what we use 80% of the time and my 13” was the perfect size for this blackberry crumble. I’m not even sure you’d categorize this as crumble but I’m also not sure what else to call it.

You could easily swap the fruit in this recipe for anything you want. I’ve done it with blueberries, blackberries, and red raspberries. We also have blackberries that grow wild but by the time that season comes on in Michigan, black raspberry season is ending. I am exhausted by then and don’t really bother too much with the blackberries. They’re at the back of the property and they take FOREVER to ripen. But we did save some and turned those into jam.
Speaking of jam, you can find my black raspberry jam recipe here!
