Ingredients
  

  • For the Baked Oatmeal
  • 2 cups gluten-free quick oats
  • 1 ripe banana
  • 1 cup unsweetened plant milk
  • ¼ cup dairy-free yogurt
  • 2 tablespoons pure maple syrup
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon baking powder
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • Cinnamon Swirl
  • 2 tablespoons vegan butter melted
  • 3 tablespoons coconut sugar
  • 1 tablespoon ground cinnamon
  • 1 tablespoon oat flour
  • Simple Vanilla Glaze
  • ½ cup powdered sugar
  • 1 –2 tablespoons unsweetened plant milk
  • ¼ teaspoon pure vanilla extract

Instructions
 

  • Step 1: Preheat the oven
  • Preheat your oven to 350°F (175°C).
  • Lightly grease a 6×9-inch baking dish or a shallow 8×8-inch baking dish.
  • A smaller baking dish will produce thicker baked oatmeal, while a larger dish will create slightly thinner portions.
  • Step 2: Prepare the oats
  • Add the gluten-free quick oats to a large mixing bowl.
  • Set aside while preparing the banana mixture.
  • Step 3: Blend the wet ingredients
  • Add the ripe banana, plant milk, dairy-free yogurt, maple syrup, vanilla extract, baking powder, cinnamon, and salt to a blender.
  • Blend until smooth and creamy.
  • Step 4: Combine the oatmeal mixture
  • Pour the blended banana mixture into the bowl containing the oats.
  • Stir until the oats are evenly coated and all ingredients are well combined.
  • Step 5: Make the cinnamon swirl
  • In a small bowl, combine the melted vegan butter, coconut sugar, cinnamon, and oat flour.
  • Stir until the mixture forms a thick, spoonable cinnamon paste.
  • Step 6: Assemble the baked oatmeal
  • Transfer the oatmeal mixture to the prepared baking dish.
  • Spread it evenly using a spoon or spatula.
  • Drizzle or spoon the cinnamon mixture over the surface.
  • Step 7: Create the cinnamon swirl
  • Use a butter knife to gently swirl the cinnamon mixture through the oatmeal.
  • Avoid mixing it completely into the oats. Keeping visible swirls creates the cinnamon roll-inspired appearance.
  • Step 8: Bake
  • Bake the Cinnamon Roll Baked Oatmeal for 35–40 minutes, or until the center is set and the edges are lightly golden.
  • Remove the dish from the oven and allow it to cool for approximately 15–20 minutes.
  • Step 9: Prepare the vanilla glaze
  • While the oatmeal cools, combine the powdered sugar, 1 tablespoon of plant milk, and vanilla extract in a small bowl.
  • Whisk until smooth.
  • Add the remaining plant milk gradually if needed to reach a thick but pourable consistency.
  • Step 10: Glaze and serve
  • Spread or drizzle the vanilla glaze over the slightly cooled oatmeal.
  • Allow the glaze to set for approximately 15 minutes for a classic glazed cinnamon roll appearance.
  • Slice into portions and serve.

Notes

For a slightly richer cinnamon flavor, add an extra pinch of cinnamon to the oatmeal mixture.
You can replace coconut sugar with light brown sugar if preferred.
If you do not have oat flour, blend a small amount of oats into a fine powder.
For a sweeter breakfast, drizzle a little additional maple syrup over individual portions before serving.
The glaze can be prepared ahead of time and stored separately until the oatmeal is ready to serve.
