These simple and tasty 3 ingredient peanut butter banana bars just require three basic ingredients! These delicious and chewy mini bars are prepared with natural foods to provide a balanced and nutritious snack for your children.

You’ll notice a few of things if you walk down the snack bar aisle at the shop. First and foremost, the collection is EXTREMELY LARGE. There are probably dozens of bars to select from.

Second, the bars are nearly entirely made of highly processed and overly sweetened components, which is disappointing. Even brands that advertise themselves as “health foods” are guilty of this.

Brown rice syrup, inulin, and tapioca starch are not recommended for daily snacking by children. As a result, we choose to produce our own snack bars that are simple, whole, and nutritious.

These three-ingredient bars have the sweet flavour and convenient size of a store-bought bar, but they’re made entirely with peanut butter, oats, and bananas (plus a couple of extra toppings!) We hope you’ll enjoy them if you enjoy lightly processed snacks created using common ingredients.

Why We Love These Bars

  • Making these bars is simple and quick with only three ingredients in the batter. It’s simple enough for your children to do.
  • Peanut butter, bananas, and oats have a good combination of carbohydrates, protein, and fats, so you can be sure your kids are getting a balanced snack.
  • The toppings are entirely up to you. The possibilities are endless, from nuts and seeds to sprinkles and chocolate chips.
  • They don’t have any added sugars (except for the ones in the chocolate chips), yet they taste like dessert!

How to Make 3-Ingredient Peanut Butter Banana Bars

If there’s one thing these bars’ components aren’t, it’s the instructions for making them. If you blink, you’ll miss them:

  • Combine mashed bananas, peanut butter, and oats in a bowl.
  • In a baking dish, press the batter.
  • Toppings should be sprinkled on top.
  • Bake.

It’s that simple!

Can you freeze 3 Ingredient Peanut Butter Banana Bars?

Yes! These bars keep well in the freezer. Simply place a square of parchment paper between each bar to prevent them from sticking together, and then place them in a gallon zip-top freezer bag.

- 3 medium banana
- 2 cup oats, dry
- 6 tablespoon peanut butter, all-natural

- 1/4 cup walnuts, chopped
- 2 tablespoons chocolate chips, dark
1. Preheat oven to 350°F and line the bottom of an 8 x 8 inch glass dish with parchment paper. (We also used our fingers to grease the sides of the dish with coconut oil.)
2. Mash the bananas and mix together with oats and peanut butter.
3. Spread the dough evenly in the prepared dish, then sprinkle with walnuts and chocolate chips. Lightly press the nuts and chocolate into the bars.
4. Bake for 18-20 minutes or until an inserted toothpick comes out clean. Cool for 20 minutes in the pan, then slide a spatula under the parchment paper and carefully transfer the whole uncut bar onto a rack for further cooling. (You can cut the bars at this point, and eat them warm! The more time you give them to cool, the easier it will be to cut them.)

  1. Is a banana and peanut butter healthy?

    A bedtime snack of a banana with peanut butter can actually help you sleep better. These components are not only excellent together, but they also complement each other. “Bananas are abundant in potassium and magnesium, which might help you relax your muscles,” says Beckerman.

  2. Are peanut butter and banana sandwiches good for you?

    Healthy unsaturated fats, protein, fibre, and complex carbs are all found in a peanut butter and banana sandwich. Its protein and fibre content keep you full, while the carbohydrates provide long-lasting energy.

  3. Is banana and peanut butter good before bed?

    A little piece of fruit, such as an apple or banana, covered in peanut or almond butter is a delicious way to stay healthy while feeling full. The potassium and magnesium in the fruit, combined with the protein and wonderful flavour of the nut butter, is the ideal combination for a restful night’s sleep!

  4. Can toddlers eat granola bars?

    These bars are high in carbohydrates and even protein, making them an excellent mid-meal snack. Granola bars can also be a good method to get carbohydrates into your child’s diet if they don’t like oats otherwise.
