Ingredients to make peanut butter baked oatmeal

• Milk – Any milk will work to help soften the oats. I used almond milk.
• Bananas– Mashed ripe bananas add a natural sweetness.
• Egg – Egg will help bind the oats and add more protein.
• Maple syrup -Use pure maple syrup to sweeten the oats. You can also use honey.
• Peanut Butter – Smooth peanut butter without added sugar is ideal; look for natural peanut butter, usually just peanuts. A drizzle of peanut butter after the oatmeal bakes is delicious!
• Baking powder – Baking powder helps the oats rise a touch.
• Cinnamon – The cinnamon adds extra flavor to the baked oatmeal.
• Salt – Add a pinch of salt to enhance the flavor.
• Rolled Oats – Stick with rolled oats for this recipe. I do not recommend making it with quick oats or steel-cut oats.
• Peanuts – Chopped peanuts, salted or unsalted, are both good options.
• Vanilla Extract
