Delicious and easy to make baked oatmeal packed with juicy blackberries and refreshing lemon. Maple syrup and vanilla add a hint of sweetness while cinnamon adds warmth. This comforting baked oatmeal is perfect for breakfast meal prep.
Add the oats, cinnamon, baking powder, and salt to a 9x9 baking dish and whisk.
Combine the chia seeds with 2 tablespoons of water and set aside for a few minutes to thicken until jelly-like.
Whisk the oat milk, maple syrup, vanilla extract, lemon juice, lemon zest, and chia egg in a bowl, then add to the baking dish. Whisk together.
Scatter the blackberries on top of the oatmeal mixture, submerging them slightly. Bake for 30-35 minutes, or until the oatmeal is fully cooked, slightly fluffy, and not at all jiggly.
Serve as is, with milk, or with a quick lemon glaze. To make the glaze, combine the above ingredients and drizzle over the baked oatmeal.
