    🛒 Ingredient notes

    Ingredients for the banana and honey flapjacks.

    Oats - use ordinary rolled porridge oats. Don't use jumbo oats as they don't absorb the melted butter mixture very well. Quick cook oats can also be used, but the texture of the flapjacks will be very soft.

    Bananas - 3 medium over rips bananas, mashed.

    Peanut Butter - smooth peanut butter for creaminess. For extra texture use crunchy peanut butter.

    Butter - unsalted butter is best.

    Honey - clear runny honey or swap for golden syrup.

    Sugar - light brown sugar gives the flapjacks a lovely squidgy texture or use demerara instead.

    Vanilla Extract - use a good quality extract and not essence for extra flavour.

    🔪 Instructions

    The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post

    Prep: Grease and line a 20cm (8 inch) square baking tin with nonstick baking paper and preheat the oven to 180°C (160°C fan/ Gas 4/ 350°F).

    1. Place the butter, peanut butter, honey, and sugar in a saucepan and melt them together on the hob over low heat. Stir continuously to prevent the mixture from burning.
    1. Remove the pan from the hob and mix in the oats, mashed bananas, and vanilla extract. Stir until combined.
    1. Press the mixture into the prepared tin.
    1. Bake in the oven for 22 minutes. Remove from the oven, score the top of the flapjack into bars with a sharp knife, and leave to cool completely.

    Top Tips

    • Grease and line your baking tin with nonstick baking paper (parchment) to ensure the flapjacks don't stick to the sides of the tin.
    • The riper the bananas, the sweeter your flapjacks will be.
    • Melt the butter, peanut butter, honey, and sugar over low heat to prevent burning and ensure a smooth mixture.
    • Firmly pack down the flapjack mixture into the tin to ensure the bars stick together and don't crumble when cut.

    🍴 Serving suggestions

    Enjoy the banana and peanut butter flapjacks as a quick and energising breakfast with a cup of coffee or tea.

    They also make a convenient on-the-go snack, a sweet addition to lunchboxes or picnics, or served as a simple dessert with vanilla ice cream!

    3. Incorporate dried fruits like raisins, cranberries, or apricots.

    5. Sprinkle in chia seeds, flaxseeds, or sunflower seeds for added texture and nutrition.
