Ingredients

Main Ingredients

  • 1 cup mashed overripe bananas (240g), about 2 medium bananas
  • 1/2 cup creamy peanut butter (125g)
  • 1 teaspoon pure vanilla extract
  • 1 3/4 cups rolled oats (175g)
  • 1 tablespoon ground flaxseeds
  • 1 teaspoon cinnamon
  • 1/2 teaspoon baking powder

Optional Add-ins

  • Grated carrots
  • Chocolate chips
  • Fruit (dried or fresh)
  • Coconut flakes

Instructions

  1. Preheat and Mash Bananas: Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). In a large bowl, mash the overripe bananas using the back of a fork or a potato masher until mostly smooth with small lumps remaining. Measure out 1 cup of mashed banana and freeze any extra for later use.
  2. Combine Ingredients: Stir in the creamy peanut butter and pure vanilla extract into the mashed bananas until fully combined. Add rolled oats, ground flaxseeds, cinnamon, baking powder, and any optional add-ins such as grated carrots, chocolate chips, fruit, or coconut. Mix everything thoroughly until all ingredients are evenly distributed.
  3. Bake the Batter: Line an 8-inch square baking pan with parchment paper or lightly grease it. Pour the batter into the pan and spread evenly. Bake in the preheated oven for 20 to 22 minutes until the bars are set and lightly golden on top. Remove from the oven and let cool completely in the pan before cutting them into 16 bars.

Notes

  • Use overripe bananas for the best natural sweetness and moisture.
  • You can substitute peanut butter with almond or any other nut butter if preferred.
  • Feel free to customize with your favorite add-ins like nuts, dried fruits, or seeds.
  • Store bars in an airtight container at room temperature for up to 3 days or refrigerate for a week.
  • These bars can also be frozen for up to 2 months—just thaw before eating.
