Ingredients

2 cups (180g) old fashioned rolled oats
1 teaspoons baking powder
¼ teaspoon salt
1 large egg
1½ cups (360ml) milk dairy or plant based
⅓ cup (80ml) pure maple syrup
1½ teaspoons pure vanilla extract
1 tablespoon melted butter or coconut oil
1 scoop (30g) vanilla protein powder optional
2 generous cups (11oz) fresh berries larger berries chopped or sliced (see note for frozen berries)

Instructions

Preheat oven to 350°F. Grease an 8x8 square baking dish and set aside.
Combine oats, baking powder, and salt. Place half the oat mixture in the baking dish, top with half the berries, and then top with the remaining oat mixture.
Whisk the egg, milk, maple syrup, vanilla, melted butter, and protein powder. Pour over the oats. Top the oats with the remaining berries. Gently shake the baking dish back and forth from side to side to allow the wet mixture to get down into the oats.
Bake uncovered for about 25-30 minutes, until the mixture is set. It will firm up as it cools.
Serve warm with milk, maple syrup, and/or yogurt.

Notes

FROZEN BERRIES:

If using frozen berries, keep them frozen and halve larger berries (like strawberries). Bake time might be a few minutes longer.

LARGER RECIPE:

You can double this recipe and bake it in a 9x13 baking pan. Bake time will likely need to be increased by a few minutes.

STORAGE:

Leftovers can be stored in the fridge for up to 4 days. Reheat individual servings in the microwave as needed. I like to add a splash of milk when reheating to make it creamy.

Recipe updated August 2025. I changed the pan size and included an option for adding protein powder. Original recipe is here.
