Ingredients
  

Banana base
  • 3 bananas Ripe bananas, mashed until completely smooth.
  • 2 cup rolled oats Rolled oats for the chewy, dense oat interior.
  • 3 tbsp honey or maple syrup Choose honey for a classic sweetness, or maple syrup for a plant-forward option.
  • 0.25 cup almond butter or peanut butter Helps bind and adds a soft-center richness.
  • 1 tsp vanilla extract Adds warmth and depth.
  • 1 tsp cinnamon For cozy flavor.
  • 0.25 tsp salt Balances sweetness.
  • 0.5 cup chocolate chips, dried cranberries, or raisins Use one mix-in option; fold in at the end.

Equipment

  • 1 sheet pan

Method
 

Prep and bake
  1. Preheat the oven to 350°F and line an 8x8 pan with parchment paper, leaving overhang for easy lifting.
  2. Mash the bananas until completely smooth, then stir in almond butter or peanut butter, honey or maple syrup, vanilla extract, cinnamon, and salt.
  3. Fold in the rolled oats until fully combined, then fold in your chosen mix-ins (chocolate chips, dried cranberries, or raisins).
  4. Press the mixture firmly and evenly into the prepared pan to help the center set.
  5. Bake for 22–25 minutes until the edges are golden and the center is set with no wet batter.
Cool and slice
  1. Cool completely before slicing into bars to prevent crumbling and help the texture firm up.
  2. Refrigerate after cooling for cleaner cuts and neatly shaped rectangles.

Notes

Pro tip: press the mixture down firmly—this is what gives the bars their dense, chewy oat interior and helps them slice cleanly. Store airtight in the refrigerator for up to 5 days; freeze up to 2 months (thaw in the fridge overnight). For a dietary swap, use almond butter and opt for chocolate chips that are dairy-free or skip chips for a dairy-free bar version.
