Scale

Dry Ingredients

  • 2 cups old fashioned rolled oats
  • 1 teaspoon baking powder
  • ½ teaspoon sea salt
  • 2 Tablespoons poppy seeds
  • 1 Tablespoon ground flaxseed

Wet Ingredients

  • 2 cups plant-based milk (such as almond, soy, or oat milk)
  • ¼ cup lemon juice (freshly squeezed)
  • Zest from 1 lemon
  • ⅓ cup maple syrup
  • 2 Tablespoons plain Greek yogurt or vegan yogurt
  • 1 Tablespoon melted coconut oil
  • 1 teaspoon vanilla extract

Fruit

  • 1 ½ cups blueberries (fresh or frozen; 1 cup for mixing into the batter and ½ cup for topping)

Other

  • cooking spray for greasing the baking dish
  • Optional toppings: extra blueberries, fresh lemon zest, yogurt, and/or maple syrup

Instructions

  1. Prep: Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch square baking dish with cooking spray to prevent sticking.
  2. Combine Dry Ingredients: In a large mixing bowl, whisk together the rolled oats, poppy seeds, baking powder, and sea salt until well blended.
  3. Mix Wet Ingredients: Add the plant-based milk, plain Greek or vegan yogurt, fresh lemon juice, lemon zest, maple syrup, ground flaxseed, melted coconut oil, and vanilla extract to the bowl with the dry ingredients. Stir until the mixture is uniform.
  4. Incorporate Blueberries: Gently fold in 1 cup of fresh or frozen blueberries into the oatmeal mixture, distributing them evenly.
  5. Pour Into Dish: Transfer the oatmeal mixture into the prepared baking dish, spreading it out evenly with a spatula.
  6. Add Topping: Scatter the remaining ½ cup of blueberries evenly over the top of the batter for a fresh burst of flavor and attractive appearance.
  7. Bake: Place the baking dish in the preheated oven and bake for 40 to 50 minutes, or until the top is golden brown and the oatmeal is set.
  8. Cool and Serve: Remove the baked oatmeal from the oven and allow it to cool for a few minutes. Portion into servings and serve warm. Garnish with additional blueberries, fresh lemon zest, yogurt, and/or a drizzle of maple syrup if desired.

Notes

  • Use fresh lemon juice and zest for the best bright citrus flavor.
  • You can substitute the plant-based milk with dairy milk if preferred.
  • Ground flaxseed adds nutrition and helps bind the oats; make sure it’s fresh for better flavor.
  • For a vegan version, use vegan yogurt and ensure your maple syrup is pure.
  • To prepare ahead, bake and refrigerate leftovers; reheat portions in the microwave or oven.
  • Frozen blueberries can be used directly without thawing to prevent the batter from turning purple.
