Instructions

Step 1: Preheat and prepare the pan

Preheat the oven to 350°F and prepare a loaf pan by greasing it lightly or lining it with a strip of parchment paper that hangs over the edges for easy removal. Doing this first makes the later transfer effortless and keeps the loaf pan clean and tidy; set the pan on the painted pine wood surface so it’s ready and within reach.

Step 2: Mash the bananas and build the wet base

Place the very ripe bananas in a large mixing bowl and mash them until they are almost smooth with a few small, yielding lumps remaining. Stir in the smooth natural peanut butter and the vanilla extract until they form a glossy, slightly elastic wet base — thick, cohesive, and scented with warm banana and peanut butter.

Step 3: Combine dry ingredients and fold in chips

Add the instant oats, salt, and baking powder to the wet mixture and stir just until everything is evenly combined; the batter should be dense, speckled with oats, and hold together when scooped. Gently fold in one third of the chocolate chips so pockets of chocolate are visible inside the batter, leaving the remaining chips set aside to press on top before baking.

Step 4: Transfer, top, and bake

Spoon the batter into the prepared loaf pan and use a spatula to smooth the top into an even, rectangular surface. Scatter the reserved chocolate chips across the top so they sit visibly on the batter’s surface. Bake until the top is golden brown and a knife inserted into the center comes out clean, about 25–30 minutes; the edges should be slightly firmer while the interior stays soft and tender.

Step 5: Cool, slice, and serve

Allow the baked loaf to cool in the pan until it firms up, then lift it out using the parchment overhang and cut into 6 to 8 generous rectangular bars. Arrange the bars in a neat rectangular cluster on fresh parchment — the interior should look moist and slightly crumbly, studded with melted chocolate chips and finished with an optional light sprinkle of coarse salt.
