Ingredients

  • 1 Tablespoon coconut oil for greasing the pan or butter
  • 2 cups (160g) old-fashioned rolled oats
  • 1 Teaspoon baking powder
  • 2 Tablespoons chia seeds
  • 1/2 Teaspoon cinnamon
  • 2 scoops vanilla protein powder
  • a pinch of salt
  • 2 cups (480ml) milk of choice
  • 2 large eggs beaten
  • 1/4 cup real maple syrup
  • 1 cup frozen or fresh blueberries

For serving (optional):

  • a dollop of yogurt, a drizzle of nut butter, or maple syrup.

Instructions

  • Preheat your oven to 350°F (175°C). Lightly grease a 7x11-inch (18 cm x 28 cm) baking dish with coconut oil or butter.
  • In the same baking dish, add the oats, baking powder, chia seeds, cinnamon, protein powder, and salt. Stir gently to combine the dry ingredients right in the dish.
  • Pour in the milk, beaten eggs, and maple syrup. Stir everything together until well combined. Let it sit for 5 minutes, and the oats will start to soak up some of the liquid. This is good!
  • Gently stir in the blueberries, spreading them out evenly throughout the mixture.
  • Bake uncovered for 35–40 minutes, or until the center is set and the edges are golden brown.
  • Let it cool slightly before slicing. Serve warm with your favorite toppings (optional).
  • Store leftovers in the fridge for up to 5 days. It’s great cold or reheated!

Notes

How do you serve baked oatmeal?
Serve it warm, straight from the oven. Slice it into squares and enjoy it as-is or dress it up with a spoonful of yogurt, nut butter, fresh fruit, or an extra drizzle of maple syrup.
Can I eat it cold?
Yes! It’s delicious cold, kind of like a soft breakfast bar. Perfect for grab-and-go mornings.
 How long does it keep?
Store leftovers in an airtight container in the fridge for up to 5 days.
Can I freeze baked oatmeal?
Definitely. Let it cool completely, slice into portions, and freeze in airtight containers or zip-top bags for up to 3 months. Reheat in the microwave or oven.
How do I reheat it?
Microwave a slice for about 30–60 seconds, or pop it in a 350°F (175°C) oven for 10–15 minutes until warmed through.
