  • 1 cup (240 g) Greek yogurt
  • ½ cup (120 g) milk
  • ¼ cup (85 g) honey
  • 1 large egg
  • ¼ cup (30 g) walnuts chopped
  • 1 teaspoon (4 g) baking powder
  • 1 teaspoon cinnamon

  • Preheat the oven to 375°F (190°C). Lightly grease an 8 x 8 inch or similar baking dish.
    Step 1 Baking dish brushed with oil.

    Step 2 Greek yogurt, milk, honey, vanilla, and egg whisked into banana mixture.
  • Stir in 1½ cups rolled oats, 1 teaspoon cinnamon, 1 teaspoon baking powder, and 1 pinch salt. Mix well so no dry oats remain. Gently fold 1 cups blueberries.
    Step 3 Oats and blueberries folded into creamy batter in mixing bowl.
  • Pour into the baking dish. Top with the remaining 1 cups blueberries and ¼ cup walnuts (chopped).
    Step 4 Oat mixture spread in baking dish topped with blueberries and walnuts.

    Let cool 5 to 10 minutes before serving.
    Step 5 Blueberry baked oats with Greek yogurt cooling down on a sun-lit marble table.
Substitutions
  • Ripe bananas → ¾ cup unsweetened applesauce, 1 cup mashed pear, or 1 cup mashed sweet potato. These are less sweet, so add about 2 tablespoons more honey to balance the flavor.
  • Rolled oats → Certified gluten free oats, or quick oats for a softer texture
  • Blueberries → Raspberries, chopped strawberries, blackberries, or mixed berries
  • Greek yogurt → Low fat Greek yogurt, Skyr for extra protein, or plain regular yogurt
  • Milk → Almond milk, soy milk, oat milk, or any dairy milk
  • Honey → Maple syrup or mashed soft dates
  • Egg → Chia egg made with 1 tablespoon chia seeds mixed with 2 ½ tablespoons water
  • Walnuts → Pecans, sliced almonds, pistachios, or pumpkin seeds
  • Baking powder → No direct substitute, do not skip
  • Cinnamon and vanilla → Pumpkin pie spice, cardamom, almond extract, or lemon zest
 
Tips
  • Use very ripe bananas for natural sweetness and a softer texture
  • Stir thoroughly so no dry oats stay at the bottom
  • Add frozen blueberries straight from the freezer
  • Let it rest 5 minutes before slicing so it sets properly
  • Taste the berries and adjust sweetness if needed
  • Store covered in the fridge up to 4 days
  • Reheat 20 to 30 seconds in the microwave for a warm, soft texture
