🥣 Ingredients

Dry Ingredients:

3 cups rolled oats (old-fashioned oats)
1 teaspoon baking powder
½ teaspoon salt
1 teaspoon cinnamon (optional)

Wet Ingredients:

2 cups milk (dairy or almond milk for dairy-free option)
2 large eggs
⅓ to ½ cup maple syrup or honey (adjust sweetness)
2 tablespoons melted butter or coconut oil
1 teaspoon vanilla extract

Optional Add-ins:

½ cup chopped nuts (walnuts, almonds)
½ cup raisins or dried cranberries
1 mashed banana (for natural sweetness)
¼ cup protein powder (for high-protein version)

👩‍🍳 Instructions

Step 1: Prepare the Oats

Preheat oven to 350°F (175°C).
Grease an 8×8-inch baking dish. Spread the rolled oats evenly in the dish.

Step 2: Make the Custard Mixture

In a mixing bowl, whisk together:

Milk
Eggs
Maple syrup or honey
Melted butter
Vanilla
Baking powder
Salt
Cinnamon

Whisk until fully combined and smooth.

Step 3: Combine

Pour the custard mixture evenly over the oats. If using add-ins like nuts or fruit, stir gently to distribute.

Let it sit for 5–10 minutes so the oats absorb some liquid.

Step 4: Bake

Bake for 35–40 minutes or until:

The top is golden brown
The center is set
A knife inserted comes out clean

Allow to cool for 10–15 minutes before slicing.
