Easy Apple Oat Crisp Recipe (old-fashioned)
Homemade apple crisp with cinnamon and a buttery crumb topping with oats. A fall dessert ready in 1 hour using basic pantry ingredients.
Servings 6 servings
Ingredients
For the apple filling:
- 6 medium apples Granny Smith or Honeycrisp are my favorites, peeled and sliced, about 6 cups
- 2-3 tablespoons sugar depending on how tart the apples are
- 1 teaspoon ground cinnamon
- 1 tablespoon lemon juice
- ½ teaspoon vanilla extract
For the oat crumble topping:
- ¾ cup old-fashioned rolled oats also called traditional oats
- ½ cup all-purpose flour
- ½ cup brown sugar
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup unsalted butter melted
Instructions
- Preheat the oven to 350°F (175°C). Lightly grease an 8x8-inch baking dish.
Make the apple mixture:
- In a bowl, toss 6 medium apples, peeled, cored and sliced with 2-3 tablespoons sugar, 1 teaspoon ground cinnamon, 1 tablespoon lemon juice, and ½ teaspoon vanilla extract.
- Pour into the prepared baking dish.
Prepare the crumble with oats:
- In another bowl, mix ¾ cup old-fashioned rolled oats, ½ cup all-purpose flour, ½ cup brown sugar, ½ teaspoon ground cinnamon, and ¼ teaspoon salt. Stir in ½ cup unsalted butter, melted until crumbly and clumpy.
- Sprinkle topping evenly over the apples.
- Bake for 40–45 minutes until the topping is golden and bubbly and the apples are soft when pierced.
- Let cool for 10 minutes on a wire rack. Serve warm on its own, with the classic vanilla ice cream and/or caramel sauce. Or with cinnamon ice cream.
Notes
Apples: I like tart apples, but you can use any variety. Adjust the sugar in the filling if using sweet baking apples, unless you like quite sweet desserts.
The topping can be chunky and rustic (mix it with your hands or a fork) or finer and more even (use the food processor), depending on how you mix the butter with the oats.
You can refrigerate leftovers in an airtight container for a few days or freeze them for a month or so. Thaw at room temperature. I also recommend warming the dessert briefly before eating so the topping crisps up again.
