Ingredients

Dry Ingredients

2 cups old-fashioned rolled oats
1 tsp baking powder
1 tsp ground cinnamon
¼ tsp salt
½ cup chopped pecans

Wet Ingredients

2 large eggs
1¾ cups milk
⅓ cup maple syrup or honey
2 tsp vanilla extract
2 tbsp melted butter or coconut oil

Fruit

2 cups fresh or frozen blueberries

Optional Toppings

Extra blueberries
Chopped pecans
Maple syrup for serving
Greek yogurt

Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C).
Lightly grease a 9×9-inch baking dish.

Step 2: Mix the Dry Ingredients

In a large bowl, combine rolled oats, baking powder, cinnamon, salt, and chopped pecans.
Stir well to evenly distribute the ingredients.

Step 3: Mix the Wet Ingredients

In a separate bowl, whisk together eggs, milk, maple syrup, vanilla extract, and melted butter.
Mix until smooth and fully combined.

Step 4: Combine Everything

Pour the wet mixture into the bowl of dry ingredients.
Stir until the oats are fully coated.
Gently fold in the blueberries, being careful not to crush them.

Step 5: Fill the Baking Dish

Transfer the mixture to the prepared baking dish.
Spread evenly with a spoon.
Sprinkle extra blueberries and pecans on top for a beautiful finish.

Step 6: Bake

Bake for 35–40 minutes.
The top should be golden brown and the center set.
A knife inserted into the center should come out mostly clean.

Step 7: Cool Slightly

Remove from the oven and let rest for 5–10 minutes.
This allows the oatmeal to firm up and makes serving easier.

Step 8: Serve

Spoon into bowls or cut into squares.
Serve warm with maple syrup, yogurt, or fresh fruit if desired.

Tips & Notes

Frozen blueberries can be used without thawing.
Pecans add crunch, but walnuts or almonds work well too.
For extra sweetness, add a sliced banana to the mixture.
Use almond milk or oat milk for a dairy-free version.
This recipe reheats beautifully for meal prep breakfasts.
