Preheat oven to 375 degrees F. Prepare an 8-inch square baking dish with nonstick baking spray.

Combine oats, almonds, sugar, baking powder, cinnamon, and sea salt in a bowl. In a separate bowl, whisk almond milk, egg, butter, and vanilla extract.

Transfer oat mixture to prepared baking dish; layer the almond milk mixture on top of oats. Scatter blueberries and strawberries on top.

Bake for 45 minutes or until golden brown and the oat mixture has set. Remove from oven; set aside to cool for 5 minutes before serving with a drizzle of honey.
