Scale

Main Ingredients

  • 2 ripe bananas (mashed; 227g)
  • 2 cups rolled oats (old-fashioned or quick oats; 178g)
  • 1 scoop vanilla protein powder (60g; I use Ora Organic)
  • 1¾ cups plant-based milk (any variety; 414ml)
  • 1 tablespoon lemon juice (freshly squeezed; 14g)
  • ½ teaspoon lemon zest (1g)
  • 1 tablespoon chia seeds (10g)
  • 1 teaspoon baking powder (10g)
  • 1 cup frozen blueberries (140g)
  • 1 teaspoon maple syrup (7g)
  • 6 tablespoons thick natural yogurt (85g)

Optional Toppings

  • Extra yogurt (as desired)
  • Peanut butter (drizzle, as desired)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (180°C) to ensure it is ready to bake the oats evenly.
  2. Mash Bananas: Using a fork, mash the ripe bananas directly in a medium baking dish until mostly smooth, creating a natural sweet base.
  3. Combine Ingredients: Add rolled oats, vanilla protein powder, plant-based milk, lemon juice, lemon zest, chia seeds, and baking powder to the baking dish. Stir thoroughly until all ingredients are fully combined, forming the oat mixture.
  4. Prepare Blueberries: Microwave the frozen blueberries with maple syrup for 1–2 minutes until they become soft and juicy, enhancing their flavor and juiciness.
  5. Add Blueberry Mixture: Spoon the warmed blueberry mixture evenly over the oat mixture in the baking dish.
  6. Swirl Yogurt: Dollop the thick natural yogurt over the top and gently swirl it into the oat and blueberry layers using a spoon for added creaminess.
  7. Bake: Place the baking dish in the oven and bake for 35–40 minutes, or until the top is golden brown and the center is just set, ensuring a warm, firm texture.
  8. Cool and Serve: Allow the baked oats to cool for at least 10 minutes before serving. Enjoy warm, optionally topped with a drizzle of peanut butter or extra yogurt for added flavor and richness.

Notes

  • Feel free to substitute plant-based milk with any milk of your choice.
  • Old-fashioned rolled oats provide a chewier texture; quick oats will yield a softer bake.
  • Letting the baked oats cool slightly helps it set better and makes it easier to slice or scoop.
  • Adding peanut butter as a topping boosts protein and adds a nutty richness.
  • This recipe can be doubled to bake in a larger dish or as meal prep for multiple servings.
