Ingredients

Scale

3 cups old-fashioned rolled oats
1 teaspoon baking powder
1/2 teaspoon fine sea salt
1 teaspoon ground cinnamon

Cook Mode Prevent your screen from going dark

Instructions

Preheat oven to 350°F (175°C). Grease a 9×13 inch baking dish.
In a large bowl, whisk together the oats, baking powder, salt, and cinnamon.
In a medium bowl, whisk the eggs. Then whisk in the maple syrup, milk, melted butter, and vanilla until smooth.
Pour the wet ingredients over the dry oat mixture. Gently fold together until just combined.
Fold in 1 1/2 cups of the blueberries, reserving the remaining 1/2 cup.
Pour the mixture into the prepared baking dish and spread evenly. Scatter the reserved blueberries on top.
Bake for 40-50 minutes, until the center is set, edges are golden brown, and a toothpick inserted comes out clean.
Let cool in the pan for 10 minutes before slicing and serving.

Notes

For best texture, use old-fashioned rolled oats, not quick oats. Let the baked oatmeal rest before slicing to allow it to set. For a dairy-free version, use plant-based milk and coconut oil. Add a scoop of protein powder to the dry ingredients for a higher-protein option.
