How to Make 4 Ingredient Peanut Butter Banana Bars
Preheat the oven: Set your oven to 350°F (175°C). Grease a 9×5 loaf pan or line it with parchment paper for easy removal later.
Mash the bananas: In a large mixing bowl, take your very ripe bananas and mash them until they’re nearly smooth, leaving a few tiny lumps for extra texture.
Mix in peanut butter: Add the natural peanut butter to the mashed bananas and, if using, pour in the vanilla extract. Stir well until everything is thoroughly combined into a creamy mixture.
Stir in the dry ingredients: Gently fold in the instant oats, salt, and baking powder. You’ll want everything evenly mixed but be careful not to over-stir; a few lumps are perfectly fine!
Add chocolate chips: Fold in 1/3 cup of chocolate chips (remember to save some for the top!). This step adds that delectable sweetness to your bars.
Transfer to the pan: Pour the golden mixture into your prepared loaf pan. Smooth the top with a spatula and sprinkle the reserved chocolate chips over the surface for an extra touch.
Bake the bars: Place the pan in your preheated oven and bake for 25-30 minutes. Keep an eye on them, and use a knife to check for doneness; it should come out clean when they’re ready.
Cool before cutting: Once baked, remove the pan and let it cool for about 10-15 minutes before slicing into 8 delicious bars.
Optional: Drizzle with a bit of honey for extra sweetness.
