Ingredients

Scale

Dry Ingredients

  • 2 cups old-fashioned rolled oats
  • 1 tablespoon chia seeds
  • 1 teaspoon baking powder
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt

Wet Ingredients

  • 1 cup unsweetened almond milk (or any plant-based milk)
  • ¼ cup pure maple syrup
  • ¼ cup unsweetened applesauce
  • 1 teaspoon vanilla extract
  • Zest of 1 lemon
  • Juice of 1 lemon

Fruit

  • 1 cup fresh or frozen blueberries

Instructions

  1. Preheat and prepare baking dish: Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish and set aside.
  2. Mix dry ingredients: In a large bowl, combine the rolled oats, chia seeds, baking powder, cinnamon, and salt. Stir these dry ingredients together until evenly mixed.
  3. Add wet ingredients: Pour in the almond milk, maple syrup, applesauce, vanilla extract, lemon zest, and lemon juice to the dry ingredients. Stir well until the mixture is fully combined and uniform.
  4. Fold in blueberries: Gently fold in the blueberries, making sure they are evenly distributed throughout the oatmeal mixture without breaking them up too much.
  5. Transfer to baking dish: Pour the batter into the prepared baking dish and spread it out evenly using a spatula or the back of a spoon.
  6. Bake the oatmeal: Place the dish in the preheated oven and bake for 35-40 minutes, or until the top is lightly golden and the oatmeal has set firmly.
  7. Cool and serve: Remove from the oven and let it cool slightly before slicing. Serve warm, optionally topped with extra blueberries or a drizzle of maple syrup for added sweetness.

Notes

  • Use either fresh or frozen blueberries based on availability; frozen blueberries do not need to be thawed before adding.
  • For a nut-free version, ensure your plant-based milk choice is also nut-free.
  • Maple syrup provides natural sweetness, but you may adjust the amount or substitute with honey if not strictly vegan.
  • Letting the baked oatmeal cool slightly helps it to set and slice neatly.
  • This oatmeal can be refrigerated for up to 5 days and reheated in the microwave or oven.
