Description
A cozy, 5-ingredient crowd-pleaser that combines creamy baked oats with tart apples and a warm, crumbly cinnamon streusel topping. Perfect for weekend brunches or make-ahead weekday mornings.
Ingredients
Scale
- 3 cups old-fashioned rolled oats
- 2 cups milk (whole milk recommended)
- 2 large eggs
- 1/2 cup brown sugar (divided)
- 3 medium apples, peeled and diced (Granny Smith and Honeycrisp mix)
- 1 teaspoon cinnamon (divided)
- 1/4 teaspoon nutmeg
- 1/2 cup all-purpose flour (for streusel)
- 1/4 cup cold butter, cubed (for streusel)
- 1/2 teaspoon cinnamon (for streusel)
- Pinch of salt
- Optional: 1/4 cup chopped pecans or walnuts
Instructions
- Preheat oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or non-stick spray.
- In a small bowl, combine flour, 1/4 cup brown sugar, 1/2 teaspoon cinnamon, and a pinch of salt for the streusel. Add cold cubed butter and rub in with fingers or a pastry cutter until coarse crumbs form. Set aside.
- In a large mixing bowl, whisk together eggs, milk, 1/2 cup brown sugar, and vanilla extract (if using) until well combined.
- Add rolled oats, diced apples, 1 teaspoon cinnamon, and nutmeg to the wet mixture. Stir to coat. Let sit for 5-10 minutes to allow oats to absorb liquid.
- Pour the oat mixture into the prepared baking dish and spread evenly. Sprinkle the streusel topping generously over the top.
- Bake for 40-45 minutes until the top is golden brown and crisp, and the center is set. If browning too quickly, cover loosely with foil for the last 10 minutes.
- Let cool for at least 10 minutes before serving to allow the custard to set.
Notes
Letting the oat mixture rest for 5-10 minutes before baking is crucial for tender texture. Use firm baking apples like Granny Smith to avoid mushiness. The recipe can be made ahead by assembling the night before and refrigerating; add 5-10 minutes to baking time if baking from cold. Stores in the fridge for up to 5 days or freezes for up to 2 months.
