Ingredients
Scale
2 cups rolled oats
1 teaspoon baking powder
1 teaspoon ground cinnamon
1/4 teaspoon salt
1/4 cup packed brown sugar
1 large egg, lightly beaten
1 1/2 cups milk (dairy or non-dairy)
1/4 cup melted butter or coconut oil
1 teaspoon vanilla extract
2 medium apples, peeled and diced
1/4 cup chopped pecans (optional, for topping)
2 tablespoons brown sugar (for topping)
1 tablespoon all-purpose flour (for topping)
1 tablespoon cold butter (for topping)
Instructions
Preheat your oven to 375 degrees F (190 degrees C). Grease an 8×8 inch baking dish.
In a large bowl, mix the rolled oats, baking powder, cinnamon, and salt.
In a separate bowl, whisk together the 1/4 cup brown sugar, egg, milk, melted butter, and vanilla extract.
Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix.
Fold in the diced apples. Pour the mixture into the prepared baking dish.
Prepare the streusel topping: In a small bowl, combine the 2 tablespoons brown sugar, flour, and pecans if using. Cut in the 1 tablespoon cold butter using your fingers or a pastry blender until coarse crumbs form.
Sprinkle the streusel topping evenly over the oatmeal mixture.
Bake for 35 to 40 minutes, or until the top is golden brown and the center is set.
Let the baked oatmeal cool for 5 to 10 minutes before cutting into squares and serving warm.
Notes
For freezer-friendly portions, cool completely, cut into squares, and freeze them individually on a baking sheet before transferring to a freezer bag. Reheat from frozen in the microwave or oven.
You can substitute blueberries or dried cranberries for the apples if you prefer a different fruit flavor.
Use quick oats for a slightly softer texture, or steel-cut oats for a chewier result (adjust cook time if using steel-cut).
