These peanut butter oat breakfast bars are an easy, healthy treat that can be prepped ahead of time for when you need breakfast on the go! The bars are loaded with mashed banana, peanut butter, and chocolate chips but you can customize them with your favorite fruit or nuts if you prefer!
In a large bowl, mash the banana then add in the peanut butter, egg, and vanilla and whisk until fully combined. Then stir in the milk.
Gently fold in the oats, brown sugar, baking powder, cinnamon, and salt until combined.
Then stir in the chocolate chips.
Let the mixture sit for 15-20 minutes so that the oats can absorbs the moisture. This will give the oatmeal bars a better texture once baked!
Cut a parchment paper sling slightly smaller than the width of the cake pan and make sure it fits flatly in the bottom. Then lightly spray the bottom and sides of the pan with a vegetable oil based spray. Place the parchment paper sling in the bottom of the pan and smooth it out so that it sticks to the pan spray (you can use metal binder clips to secure it to the pan).
Pour the mixture into your lined pan and smooth into an even layer.
Bake at 350°F for 25-35 minutes or until the center is fully set.
Remove from the oven and let cool to room temperature.
Cut into bars and store in an airtight container in the fridge for up to 5 days! You can serve them cold or warm!
Notes
For best results, use processed peanut butter like Jif or Skippy that doesn't separate. Natural peanut butter has too much oil and will negatively affect the recipe.
