Ingredients

Scale

2 cups old-fashioned rolled oats
1 teaspoon baking powder
1 teaspoon ground cinnamon
1/2 teaspoon fine sea salt
2 large eggs, lightly beaten
1 3/4 cups milk

Cook Mode Prevent your screen from going dark

Instructions

Preheat oven to 375°F (190°C). Grease an 8×8-inch or similar 2-quart baking dish.
In a large bowl, whisk together the oats, baking powder, cinnamon, and salt.
In a separate medium bowl, whisk the eggs, milk, maple syrup, melted butter (or oil), and vanilla until smooth.
Pour the wet ingredients into the dry ingredients. Gently fold with a spatula until just combined.
Gently fold in the blueberries (and most of the nuts, if using).
Pour the batter into the prepared dish, spreading evenly. Top with reserved nuts or a sprinkle of brown sugar, if desired.
Bake for 35-40 minutes, until the top is golden brown, edges pull away, and a toothpick inserted in the center comes out clean.
Let the baked oatmeal rest in the pan for 10 minutes before slicing and serving.

Notes

For best texture, use old-fashioned rolled oats, not quick oats. Let the oatmeal rest after baking for clean slices. To prevent fresh blueberries from sinking, toss them in a tablespoon of flour or oats before folding in. The dish can be assembled the night before and baked in the morning.
