Nutella and Banana Toastie

By toastiemaker.com · Updated 16 Oct 2026

A Nutella and banana toastie needs less heat time than a savoury one: about 2½–3 minutes in a standard toastie maker. Hazelnut chocolate spread is around half sugar and scorches fast, so spread it only in the centre with a 2cm clean border, put the banana on top of it, and butter the outside thinly. You get a crisp shell with a molten middle and nothing welded to the plates.

Why sweet toasties need different rules

Savoury fillings are mostly protein, fat and water. Sweet ones are mostly sugar, and sugar behaves very differently on hot plates. Toastie maker plates run at roughly 200–230°C once preheated, well above the point where sugar caramelises (around 160–180°C) and then burns. Any chocolate spread that reaches the crimped edge caramelises within a minute and then turns to bitter, black carbon that bonds to the non-stick coating.

The 2cm border is wider than the 1cm used for cheese because chocolate spread loosens and flows as it warms. Spreading it on only one slice keeps the total amount sensible, and the banana on top acts as a cap that slows it spreading outwards. The shorter cook time works because there's no cheese to melt: the spread only needs to soften, and the banana to warm through.

Thin butter on the outside matters too. Brioche and enriched breads already contain sugar and butter and brown quickly; adding a thick butter layer makes them catch. Plain white bread is the safest choice for first attempts. See best bread for toasties for how enriched loaves behave.

If sugar does stick to the plates

Unplug the machine, open it and let it cool for 5 minutes until warm rather than hot. Lay a damp, folded piece of kitchen paper over the residue, close the lid and leave it 5 minutes: the steam softens the caramel so it wipes away. Never scrape with metal. Our guide on why your toastie is sticking explains how repeated sugar burns damage coatings, and the cleaning guide covers removable plates.

Other machines and methods

In a deep fill toastie maker, use a whole small banana and 30g spread; cook for 3–3½ minutes. A panini press isn't ideal for this, since the open sides let the spread escape; if you use one, cook 2½–3 minutes and keep the border at 2cm. In a frying pan, use low-medium heat for 1½–2 minutes a side. In the air fryer, 170°C for 5–6 minutes.

Variations

• Peanut butter and banana: 20g smooth peanut butter instead of the chocolate spread. It burns slightly less readily but still needs the border.
• Strawberry: 3 sliced strawberries instead of banana, patted dry.
• Banana and biscoff: spiced biscuit spread instead of chocolate. It's very sugary, so check at 2 minutes.
• Chocolate and marshmallow: see our s'mores toastie for how to stop marshmallows escaping.
• Warm and spiced: try the apple pie toastie for a cinnamon version.

Mistakes to avoid

• Spreading to the edges: guaranteed to burn and stick.
• Using the full savoury cook time: 4–5 minutes will over-brown the bread and scorch any escaping spread.
• Overripe, mushy banana: lovely flavour but releases liquid. Use ripe but firm.
• Sugar on the outside: a sprinkle of sugar on the butter caramelises straight onto the plates. Leave it off.
