Key Ingredients and Their Benefits
Peanut Butter
Peanut butter is the star of this recipe. It’s rich in healthy fats and protein, which are essential for maintaining energy levels and supporting muscle recovery. Additionally, peanut butter is a good source of antioxidants and has heart-healthy properties. The fats in peanut butter are mostly monounsaturated and polyunsaturated fats, which can help reduce bad cholesterol.
Bananas
Bananas are a great addition to these bars because they provide natural sweetness and moisture. They’re high in potassium, which helps regulate blood pressure, and they’re also a good source of vitamin B6, which supports brain health. Bananas contain soluble fiber, which aids in digestion and helps keep you feeling full for longer periods.
Oats or Ground Almonds
Oats are an excellent source of fiber, which is essential for digestive health. They also help stabilize blood sugar levels, providing you with a sustained source of energy throughout the day. Oats are rich in important nutrients such as magnesium, iron, and B-vitamins, which are all important for maintaining a healthy metabolism.
Honey
Honey is the natural sweetener in this recipe. It’s packed with antioxidants and has antibacterial properties that can help improve digestion. Honey provides quick energy, and since it’s a natural sweetener, it’s a healthier alternative to refined sugar. It also helps bind the ingredients together, giving the bars the right consistency.
How to Make 4 Ingredient Peanut Butter Banana Bars
These bars are incredibly simple to make, and the best part is they don’t require baking. Let me walk you through the process step by step.
Step-1: Prepare the Bananas

Start by peeling two ripe bananas and placing them in a medium-sized bowl. Use a fork or potato masher to mash the bananas until they reach a smooth consistency. Leave a little texture for a more satisfying bite, but ensure there are no large chunks. The riper the bananas, the sweeter your bars will be, so make sure they’re soft and speckled with brown spots.
Step-2: Mix Peanut Butter, Honey and Oats


Combine 1 cup of peanut butter and 2 tablespoons of honey. Then, Stir everything together until the bananas are fully incorporated. Then, add 1 cup of rolled oats to the mixture and mix until the oats are evenly distributed. The oats will help give the bars texture and keep you feeling full.
Step-3: Line a Baking Dish

To make removing the bars easier, line a square or rectangular baking dish with parchment paper. This will prevent the bars from sticking to the pan and make cleanup a breeze. You can also lightly grease the pan with a small amount of coconut oil or butter if you prefer.
Step-4: Press the Mixture Into the Dish

Transfer the mixture into the prepared dish and use a spatula or the back of a spoon to press it down evenly. Make sure the mixture is compact, as this will help the bars hold together once they’ve set. Press the mixture down firmly to ensure everything sticks together.
Step-5: Chill or Bake the Mixture

Place the dish in the refrigerator for at least one hour to allow the bars to set or bake the mixture at 325F (160C) for 20-25 minutes. The chilling or baking process is crucial for the bars to hold their shape when cut.
Step-6: Cut and Serve


Once the bars have firmed up, remove them from the fridge or freezer. Carefully cut them into squares or rectangles, depending on your desired serving size. These bars are now ready to be enjoyed!
