Slow Cooker Peanut Butter Banana Oatmeal Bars combine all the goodness of wholesome oats, ripe bananas, and creamy peanut butter into a convenient breakfast that's perfect for on-the-go!
Heat up peanut butter in a medium/large glass mixing bowl in the microwave until soft. This will make it easier to incorporate into the other ingredients.
Add bananas to the peanut butter and mash them. Add the oats, honey, and vanilla to the bowl with the mashed banana/peanut butter. Stir to combine, then fold in the peanut butter chips.
Line the slow cooker with parchment paper, then pour the oatmeal mixture into the slow cooker. I like to push a couple extra peanut butter chips in the top because it looks nice.
Place the lid on the slow cooker and cook for approximately 2 1/2 hours on low. Check them at 2 hours and 15 minutes, as some slow cookers run hotter than others and we don't want to burn them. They should be soft, yet firm enough to stay together and golden brown.
To remove from slow cooker, pull the parchment paper out and carefully set it down on a flat surface. Cut bars and store in an air-tight container. Bars are best when warm. For the best texture, I like to warm up the leftovers in the microwave before serving. Enjoy!
Notes
I tested this recipe with Skippy Natural Peanut Butter. It contains peanuts, sugar, oil, and salt. If your peanut butter doesn't contain sugar, your bars will be less sweet.
Feel free to use creamy or chunky peanut butter for this recipe. I have made it with both types, and it comes out great either way.
Store the cooked oatmeal bars in an air-tight container in the refrigerator for up to 4 days.
If not eating fresh, I recommend popping them in the microwave to soften them.
