Juicy, tender apples topped with crunchy, cinnamon streusel make the perfect holiday dessert! Substitute with oat flour for a gluten-free treat!
Preheat oven to 350°F/180°C. Lightly grease a 9-inch round or an 8-inch square baking dish. Set aside.
Make the apple filling:
In a medium bowl, toss apples with lemon juice. Add all other ingredients and toss evenly to coat. Transfer mixture to prepared baking dish and spread evenly. Set aside.
Bake for 30-40 minutes, until topping is golden brown and juices are bubbling. The apples should be tender when a toothpick is inserted, but not mushy. If the top is browning too fast, cover loosely with aluminum foil. Allow to cool for a few minutes on a wire rack until warm. Serve warm and, if you like, add ice cream, vanilla brown sugar frozen custard, or whipped cream.
