This delicious blackberry and apple crumble is one of those desserts that you can throw together in a flash.
You make it with fresh or frozen fruit, and I’ve even thrown in some make-ahead tips because life is busy, but dessert should never be an afterthought.
Pro Tips/Recipe Notes
- Spoon the flour into the measuring cup instead of the ol’ “scoop and dump” method. That will pack the cup too full and will produce a dry crumble topping.
- Sustainability tip: to save money and resources, use the leftover butter wrapper to grease the baking dish.
- If you leave the peel on the apples, consider selecting apples with thinner skin such as Fuji or Braeburn. Granny Smith apple peels can be somewhat thick when baked.
- If your apples are extra sweet, you can leave out the 1/4 cup of sugar altogether. If they are extra tart, increase the sugar to 1/3 cup.
