    How to Make Peanut Butter Banana and Chocolate Blondie Bars

    1. Preheat the oven to gas mark 4/350oF/180oC/160oC and line a rectangle baking tin which measures approximately 13 x 9 inches. In a bowl, combine all the dry ingredients (plain flour, salt, cornflour and bicarbonate soda) then set aside.

    2. In a microwavable bowl, add the butter and microwave in 40 second increments until fully melted. Remove and set aside to cool.

    3. To the butter, add the brown sugar and granulated sugar then mix until smooth. Mix in the vanilla extract then the eggs and continue to mix. Add and mix in the mashed banana and peanut butter then fold in the dry ingredients and combine well. Lastly, add and mix in the chocolate chips.

    4. Pour the batter into the prepared baking tin and bake for 35 - 40 minutes. Once baked, allow to cool completely before cutting.

    Recipe Tips

    • Once the blondies have baked, ensure they are completely cooled before you attempt to cut them.
