Peanut Butter Banana Oatmeal Bars

Like your mom always told you, breakfast is the most important meal of the day. But if you’re like me, sometimes eating breakfast is the last thing you actually want to do when waking up in the morning. As soon as my feet hit the floor I’m in super speed mode and stopping to eat just isn’t in the itinerary.

But I know how important breakfast is, so no matter how I actually feel, I always try to eat something. Whether it’s a sausage, egg and potato breakfast wrap, a Mini Berry Breakfast Parfait, Pineapple Banana Orange Breakfast Smoothie, or a boring bowl of egg whites, I try to make sure it has some protein to give me a good jump start on the day.

These easy Peanut Butter Banana Oatmeal Bars are a fun and easy way to get in your breakfast each morning.

What is there not to love about these Peanut Butter Banana Oatmeal Bars? They’re not only perfect for an easy-to-grab-quick breakfast, they’re also a perfect after school snack! All that learning at school makes my children come home ravenously hungry.

      I definitely do not get enough protein in my diet, so this is a great way to sneak some in there 🙂 I can’t wait to try these!

      Those look delicious! With those oats and banana, this is a much healthier alternative to brownies.

      My daughter would love this before soccer, it would give her “power” as she calls it. Once the season starts I’ll make them for her.

    4. 4

      I would love to make things. My husband and my son both hate peanut butter so I would be the only one eating them so I could be a problem for me LOL. Maybe I’ll make them the next time we have friends over.
