When it is freezing outside in Canada or the northern United States, there is nothing more comforting than a big mug of thick, creamy hot chocolate. This banana hot chocolate takes the idea of classic hot cocoa and turns it into a rich drinking chocolate, with caramelized bananas, a hint of rum if you like, and deep dark chocolate. It is inspired by my original “chocolat chaud costaud” video, but I adjusted the proportions so the recipe is smoother, easier to drink, and more reliable.

The banana is first caramelized in cane syrup, then deglazed with a splash of rum. Everything is blended with hot milk and folded into a dark chocolate ganache. The result is a hot chocolate that feels halfway between a classic European-style drinking chocolate and a dessert cream, with a strong banana flavor and a silky finish. There is also an option to make it extra thick, closer to the version in my video, for anyone who loves a spoonable hot chocolate.

You can serve this cozy drink after a winter dinner like creamy Roquefort sauce chicken tenderloin, with a dessert such as ultra rich chocolate mousse, or as a sweet treat on its own while your homemade Korean fried chicken or authentic Belgian fries are crisping in the kitchen.

Why this banana hot chocolate works

Balanced thickness – The original video version was very “costaud” and could become almost like a pudding. Here the ratio of bananas to milk and cream is adjusted so it stays drinkable, while you still have an option for an ultra-thick version.
Caramelized banana flavor – Cooking the banana in cane syrup and deglazing with rum concentrates the flavor instead of just blending raw banana into milk.
Real chocolate – This recipe uses dark chocolate, not just cocoa powder, for a deep flavor and a naturally thick texture similar to European drinking chocolate.
Silky texture – The banana mixture is blended and strained, then folded into the ganache so you do not end up with fibrous bits.
Perfect for cold weather – This drink pairs naturally with cozy recipes like classic French onion soup, Welsh rarebit, or a slice of moist apple cake.

Ingredients for banana hot chocolate

For 2 generous mugs.

For the banana base

1 large ripe banana (about 120 g peeled)
15 ml (1 tbsp) cane syrup or maple syrup
30 ml (2 tbsp) dark rum, optional
240 ml (1 cup) whole milk, divided

For the chocolate ganache

120 g (4.2 oz) dark chocolate (around 60–70%), chopped
180 ml (¾ cup) heavy cream 35%
240 ml (1 cup) whole milk
1 ml (¼ tsp) fine salt
5 ml (1 tsp) pure vanilla extract
1 ml (¼ tsp) ground cinnamon, optional

To serve

Whipped cream (homemade or from your siphon)
Shaved chocolate or cocoa powder
Banana slices, caramelized in a dry pan if you like

For a dessert night, this drink sits perfectly alongside a dish of no churn dark chocolate ice cream or a piece of foolproof lemon meringue pie.

Step-by-step: how to make banana hot chocolate

1. Caramelize the banana

Peel the banana and slice it into thick rounds. In a medium skillet, add the cane syrup and warm it over medium-low heat. When the syrup starts to bubble, add the banana slices in a single layer. Cook for 30–40 seconds per side, until lightly golden and fragrant.

Pour in the dark rum, if using, and let it bubble for a few seconds so the alcohol evaporates. You should smell the aroma of rum without a strong alcoholic bite. Add about 120 ml (½ cup) of the milk, let it warm up, then remove from the heat.

Use an immersion blender directly in the pan, or transfer everything to a blender. Blend until completely smooth. For an ultra silky texture, pass the mixture through a fine sieve into a bowl or jug, pressing with a spatula to extract all the banana cream.

2. Prepare the chocolate ganache

In a saucepan, combine the chopped dark chocolate, heavy cream, and the remaining 240 ml (1 cup) of milk. Heat on low, whisking constantly, until the chocolate is fully melted and the mixture is smooth. Do not let it boil; keep the heat gentle.

Add the salt, vanilla extract, and cinnamon if using. The ganache should be glossy, thick, and pourable, similar to the base of a classic hot chocolate but richer. If you like recipes like creamy mozzarella parmesan pasta, you will recognize this idea of a smooth, emulsified base.

3. Combine banana and chocolate

Pour the warm banana mixture into the saucepan with the ganache, whisking constantly. Keep the heat on low and let everything come together. The hot chocolate will thicken slightly as the banana starch blends with the melted chocolate.

If the mixture seems too thick for your taste, add a splash of extra milk until you reach the consistency you like. If it is too thin, simmer gently for 1–2 minutes, whisking, but do not boil.

4. Serve

Preheat your mugs with hot water, then pour in the banana hot chocolate. Add whipped cream, shaved chocolate, or a few caramelized banana slices on top. Serve immediately while warm and silky.

This drink is a beautiful finish after hearty mains such as spaghetti with meat sauce or maple chicken with creamy mashed potatoes.

Substitutions and variations

Extra thick hot chocolate, “costaud” style
For a very thick drinking chocolate closer to the original video, use 2 bananas instead of 1 and reduce the total milk in the ganache by 60 ml (¼ cup). Keep an eye on the texture and thin with a little hot milk at the end if needed.
No rum version
Simply omit the rum and use extra milk or a little orange juice to deglaze the pan. The banana will still caramelize nicely.
Dairy-free banana hot chocolate
Replace milk and cream with a mix of almond milk and coconut milk. Full-fat coconut milk will give a texture similar to heavy cream. This version is excellent with a side of homemade crispy waffles.
Cocoa powder instead of chocolate
In a pinch, use 30 g (⅓ cup) unsweetened cocoa powder and 60 g (⅓ cup) dark chocolate chips instead of the full 120 g chocolate bar. The bar gives the best result, but the mix still works.
Spiced banana hot chocolate
Add ground nutmeg, cardamom, or a tiny pinch of cayenne. These warm spices pair beautifully with hot drinks and with recipes like spicy baked chicken wings.

FAQ – Banana hot chocolate

Can I make this banana hot chocolate ahead of time?
Yes. Prepare the banana-chocolate mixture, let it cool, then refrigerate for up to 2 days. Reheat gently on low heat, adding a splash of milk if it thickens too much.

Can I freeze leftover hot chocolate?
For the best texture, it is better not to freeze the drink as-is. However, you can freeze it in ice cube trays and use the cubes later to blend into a banana chocolate frappé with cold milk.

What type of chocolate is best?
Use a dark chocolate between 60% and 70%. A bar that you would enjoy eating on its own gives the best result. Very bitter chocolate (over 80%) will need extra sweetener.

Can I reduce the sugar?
Yes. Use just half a tablespoon of cane syrup, or replace it with a small splash of maple syrup. The banana already brings a lot of natural sweetness, especially if it is very ripe.

How do I make it kid-friendly?
Simply remove the rum completely. Caramelize the banana in syrup alone, then proceed with the recipe. Serve without alcohol alongside kid-friendly dishes like crispy homemade chicken tenders.
