Preheat oven to 375°F. Spray an 8x8 square baking pan with nonstick spray. Set aside.
In a large bowl, stir the oats, ⅓ cup brown sugar, baking powder, cinnamon, salt, strawberries, and almost all of the chocolate chips together. Pour the mixture into the baking dish and smooth out completely. Sprinkle with the remaining chocolate chips.
2 cups old-fashioned rolled oats, 7⅓ tablespoons brown sugar, 1 teaspoon baking powder, 1 teaspoon ground cinnamon, ½ teaspoon kosher salt, 1½ cups sliced strawberries, ½ cup milk chocolate chips
Using the same bowl, whisk together the milk, egg, butter, and vanilla. Pour the milk mixture over the oat mixture, making sure to cover the entire mixture. Tap the dish on the counter lightly to make sure its evenly distributed.
2 cups whole milk, 1 large egg, 3 tablespoons unsalted butter, 2 teaspoons pure vanilla extract
Bake for 40 minutes, or until the edges are bubbly and the top is golden. The center should not jiggle.
Remove from the oven and sprinkle with the remaining 2 tablespoons brown sugar. Switch the oven to high broil and allow the oatmeal to toast for approximately 2-3 minutes. Watch it closely to make sure it doesn't burn.
Remove from the oven and serve topped with fresh whipped cream, sliced strawberries, extra chocolate chips, or chocolate syrup. Toasted walnuts would also be tasty!
