🛒 Ingredient notes

Ingredients for banana oat cookies.

Bananas — Use two small overripe bananas, mashed until smooth.

Oats — Porridge or rolled oats work best. Avoid instant or jumbo oats for texture reasons.

Butter — Unsalted, softened so it creams easily with the sugar.

Sugar — Light brown sugar gives moistness and a gentle caramel note.

Egg — One large egg, at room temperature.

Vanilla extract — Adds warmth; vanilla bean paste can be substituted.

Honey — Clear runny honey helps bind and sweeten; golden syrup is an alternative.

Flour — Plain (all-purpose) flour to give structure.

Bicarbonate of soda — For lightness and lift.

Salt — Just a pinch to balance the sweetness.

Chocolate chips — Milk or white chocolate chips, or chopped chocolate if preferred.
