A wholesome breakfast combining hearty oats, fresh blueberries, and bright lemon flavors. Easy to make and perfect for feeding a crowd.

# What goes in:

→ Dry Ingredients

01 - 2 cups old-fashioned rolled oats
02 - 1/2 cup chopped walnuts or almonds
03 - 1 teaspoon baking powder
04 - 1/2 teaspoon ground cinnamon
05 - 1/2 teaspoon salt

→ Wet Ingredients

06 - 2 cups milk
07 - 1/4 cup maple syrup or honey
08 - 2 large eggs
09 - 1/4 cup unsalted butter, melted
10 - 1 tablespoon lemon zest
11 - 1 teaspoon pure vanilla extract
12 - 2 tablespoons fresh lemon juice

→ Add-ins

13 - 1 1/2 cups fresh or frozen blueberries

→ Topping

14 - 2 tablespoons coconut sugar or brown sugar

# Directions:

01 - Preheat the oven to 350°F. Lightly grease a 9x9-inch baking dish with cooking spray or butter.
02 - In a large bowl, combine rolled oats, nuts (if using), baking powder, cinnamon, and salt. Mix thoroughly to distribute the baking powder and spices evenly.
03 - In a separate bowl, whisk together milk, maple syrup, eggs, melted butter, lemon zest, vanilla extract, and lemon juice until completely blended and smooth.
04 - Pour the wet ingredients into the dry ingredients. Stir gently with a spatula until just combined, being careful not to overmix.
05 - Gently fold in the blueberries, taking care to distribute them evenly without crushing them.
06 - Transfer the mixture to the prepared baking dish and spread evenly with a spatula. Sprinkle with coconut sugar or brown sugar if using.
07 - Bake for 35 minutes, or until the top is golden brown and the oatmeal is set. A toothpick inserted in the center should come out clean.
08 - Allow to cool for 5 minutes before serving. Serve warm, with extra milk or yogurt if desired.
