Ingredients to make peanut butter baked oatmeal

All the ingredients on a countertop 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

How to make peanut butter baked oats

Step 1: Preheat oven to 350 degrees. Spray a baking dish with cooking spray.

Step 2: In a large mixing bowl, combine mashed bananas, milk, egg, maple syrup, peanut butter, baking powder, cinnamon, salt, and half of the chopped peanuts.

Step 3: Mix the rolled oats with the wet ingredients. Pour the oats into the prepared baking dish and let them sit for 10 minutes. Top the mixture with the rest of the peanuts, and bake for 40 -50 minutes. The edges of the oatmeal will start to turn golden brown.

Storage

Fridge: Cool leftover oatmeal to room temperature before storing it in an airtight container in the fridge for up to 3-4 days. Or cover the baking dish with plastic wrap and place it in the fridge. If the oats are too thick the next day, add a splash of milk to the top of the oats after warming.

Freezer: Overnight oats can be frozen for up to 3 months. Thaw in the fridge overnight and reheat the next day.

Rewarm: Rewarm leftover oats in the microwave in 30-second increments.
