Preheat oven to 350°. Spray a 2-quart baking dish or 8x8 pan with cooking spray.
To make the topping, mix the almonds, oats, brown sugar, flour, cinnamon, and salt in a small bowl with a fork. Pour in the melted butter and mix until clumps form. Set aside.
If using an egg replacer, make your “egg” and set aside.
Whisk almond milk, egg replacer, brown sugar, salt, vanilla, and almond extract until well combined. Stir in oats and stir well.
Pour oatmeal mixture into prepared pan. Add berries and arrange over oatmeal. Sprinkle evenly with topping.
Bake for 50 minutes, or until set and golden brown. Serve with a sprinkle of powdered sugar if you like and some non-dairy yogurt.
