Equipment

  • 9x13 inch (23 x 33 cm) baking pan*

Ingredients

  • 1 cup unsalted butter (226 grams)
  • 2 cups white sugar (400 grams)
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup mashed bananas (240 ml) about 2-3 large, brown bananas

US Customary - Metric

Instructions

  • Preheat the oven to 350F degrees (180C or 170C fan forced). Line a 9x13 inch (23x33 cm) pan with parchment paper or aluminum foil leaving an overhang around the sides. Alternatively, lightly grease the pan.
  • Add the butter and sugar to a large bowl. Microwave for 45 seconds on medium power, then remove from the microwave and stir. Repeat the process until the butter is melted. Alternatively, melt in a double boiler.
  • Allow the mixture to cool slightly, then whisk in the eggs and vanilla extract.
  • Stir in the mashed bananas.
  • If the cocoa is lumpy, sift it first. Then gently whisk the flour, cocoa powder, and salt into the batter. Note: there will be lumps in the batter from the banana.
  • Stir in the chocolate chips.
  • Pour/spoon the batter into the prepared pan and bake for about 35 minutes, or until an inserted toothpick comes out clean or with a few damp crumbs.
  • Cool fully (about 4 hours), then slice. Store brownies in an airtight container in the fridge for up to 4 days.

Notes

  1. For a Smaller Batch: Divide the recipe in half and bake in an 8x8 inch (20x20 cm) pan. The bake time will be 30-35 minutes. You'll need:
    • ½ cup butter
    • 1 cup sugar
    • 1 large egg
    • ½ teaspoon vanilla extract
    • ½ cup mashed banana
    • ½ cup plus 2 tablespoons all-purpose flour
    • ¼ cup plus 2 tablespoons cocoa powder (6 tablespoons in total)
    • ¼ teaspoon salt
    • ¾ cup chocolate chips
  2. Bananas: You'll need about 2-3 large bananas or 3-4 smaller bananas. Make sure the bananas are brown and spotty.
  3. Nutrition: Details provided are an estimate only and based on 1 brownie, assuming the pan is sliced into 18 equal pieces. 
  4. Storage: Store cooled brownies in the fridge for up to 4 days. Because these brownies are incredibly moist, I recommend storing in the fridge or they can go bad quite quickly.
