Prep
- Preheat oven to 350F. Line an 8x8-inch pan with parchment, leaving overhang on two sides for easy removal. Lightly butter the exposed sides.
- In a medium saucepan over low heat, melt butter with 3/4 cup chocolate chips and cocoa powder, stirring constantly until smooth and glossy, about 3-4 minutes. Remove from heat and let cool slightly, 2-3 minutes.
- Whisk sugar into the warm chocolate mixture until combined. Add eggs one at a time, whisking well after each. Stir in vanilla and mashed banana - the batter will look slightly curdled but smooths out.
- Switch to a rubber spatula. Fold in flour and salt until just combined with no streaks remaining. Fold in remaining 1/4 cup chocolate chips. The batter will be thick and glossy.
- Spread batter evenly in prepared pan. Bake 32-36 minutes until a toothpick inserted in the center comes out with moist crumbs but no wet batter. The top will look matte and slightly crackled. Do not overbake.
- Cool completely in pan on a wire rack, at least 1 hour. Use parchment overhang to lift out, then cut into 16 squares. For cleanest cuts, wipe your knife between slices.
Notes
Use very ripe bananas with black spots for maximum moisture and sweetness - they should mash almost to a liquid. For extra fudgy brownies, err on the side of underbaking; the center will set as they cool. These keep well at room temperature for 3 days or frozen for up to 2 months - wrap individual squares in plastic wrap, then foil.
