Ingredients
 

Blueberry Apple Filling

  • 5 apples of choice about 5.5 - 6 cups
  • 1 ½ cups blueberries fresh or frozen (thaw first)
  • 2 tablespoons coconut sugar or another granulated
  • 2 teaspoons ground cinnamon
  • 1 tablespoon lemon juice
  • 2 tablespoons all-purpose flour use gluten-free if needed

Oat Crumble Topping

  • cup old fashioned rolled oats use gluten-free if needed
  • cup all-purpose flour use gluten-free if needed
  • ½ cup brown sugar
  • 6 tablespoons room temperature butter dairy-free or regular
  • ¼ teaspoon kosher salt reduce to ⅛ if using another type

Instructions

  • Preheat the oven to 350°F.
  • Prepare the fruit filling. Peel, core, and cut the apple into thin slices (roughly ¼-inch thick). Add the sliced apples to a large bowl along with the blueberries, coconut sugar, ground cinnamon, lemon juice, and flour.
  • Transfer the apple mixture to your baking dish or skillet and spread it into a somewhat even layer.
  • In a medium bowl, prepare the dry ingredients. Combine the rolled oats, flour, brown sugar, and salt. Add in the softened butter, squeezing it through the mixture with your hands until you have a crumbly texture. 
  • Spoon the oat crumble topping over the filling. Bake uncovered for 45 minutes. Allow it to cool down for a few minutes before digging in. Serve with a scoop of vanilla ice cream.

Notes

How to store

Fridge: allow it cool completely and then cover with plastic wrap or aluminum foil and store it in the fridge for up to 5 days. To prevent the topping from getting soggy in this time frame, I recommend not transferring it to an airtight container and just keeping it in the dish you cooked it in.
Freezer: allow it to cool completely, and then cover it tightly with plastic wrap and foil. Place it inside a freezer-safe bag where it'll keep for up to 3 months.

Make It Your Way: Substitutions & Variations

No butter? - use refined coconut oil for no coconut taste.
No blueberries? – you can also use cherries, cranberries, raspberries, or pears.
No coconut sugar? - sub white sugar, cane sugar, or maple syrup instead.
Add chopped nuts - a handful of chopped pistachios, almonds, walnuts, or pecans would add a nice nuttiness.
