    Serves: 24 

    • 125g butter, softened
    • 1 cup (220g) white sugar
    • 1 egg
    • 1 teaspoon vanilla essence
    • 1 1/2 cups mashed bananas
    • 1 1/2 cups (185g) plain flour
    • 1 teaspoon bicarbonate of soda
    • 1 teaspoon baking powder
    • 1/2 teaspoon salt
    • 1/4 cup (30g) cocoa powder

    Preparation:15min  ›  Cook:25min  ›  Ready in:40min 

    1. Preheat an oven to 180 degrees C. Grease a 20x30cm baking dish.
    2. Beat the butter and sugar with an electric mixer in a large bowl until light and fluffy. Add the egg and the vanilla and beat until well combined. Stir in the mashed banana, set aside.
    3. Stir together the flour, bicarb soda, baking powder and salt in a separate large bowl and make a well in the centre. Pour the banana mixture into the well and stir just until combined.
    4. Remove half of the batter from the bowl. Mix the cocoa powder into the batter remaining in the bowl and stir well. Spread the cocoa batter in the bottom of the prepared tin. Spoon the remaining batter on top and use a knife to swirl the batter into a marbled design.
    5. Bake in the preheated oven until the edges are golden, about 25 minutes. Allow to cool before cutting into 24 pieces.

    I make these all the time for Potluck...the only bad thing about them is keeping DH from devouring them all before-hand! I usually put the chocolate layer on top so I only have to use one bowl. I also sometimes add walnuts and/or chocolate chips. Yummy!  -  26 Jan 2009  (Review from Allrecipes USA and Canada)


    This is a great recipe! Don't change anything! Too many people add and/or change recipes - this is great as shown!!  -  26 Jan 2009  (Review from Allrecipes USA and Canada)


    Wow!!! This really is "the Best!" I followed the recipe with amazing results. The only minor problem I had was that the batter was slightly dry. I used two large bananas and I didn't really measure it out to 1 1/2 cups. Next time I would add 4 bananas to make it more moist. I had to add some milk to the cocoa mixture to thin it out, but otherwise it was fabulous.  -  28 Jan 2009  (Review from Allrecipes USA and Canada)
