Made in the slow cooker, it is ideal for warming up on chilly days when you fancy something a little more indulgent than an ordinary mug of hot chocolate.

Italian Style Thick Hot Chocolate
Have you had hot chocolate abroad that is so thick you can nearly stand your spoon up in it?
Italian style hot chocolate, or cioccolata calda, is made with chopped real dark chocolate and thickened with a little cornflour to give a lovely thick glossy drink which is almost like a dessert. It is often served in smaller cups with a spoon. Yum!
I’ve adapted this idea to a slow cooker so that you can make your own thick and creamy hot chocolate at home and serve this rich and indulgent treat whenever you want.

Ingredients
Here are the ingredients you will need (quantities are in the recipe card below):

- milk – I use semi-skimmed normally. Full fat or skimmed milk can also be used.
- whipped or spray cream – use your favourite kind of cream to top your hot chocolate.
- cocoa powder – I use standard cocoa powder for baking.
- sugar – caster or granulated sugar can be used, to sweeten.
- dark chocolate – dark chocolate brings a deep chocolate flavour. If you like you can use milk chocolate but the flavour won’t be as rich.
- cornflour (corn starch) – to thicken.
Method
Here is the method to make this thick and creamy slow cooker hot chocolate. Find the quantities in the recipe card at the end of the post.

Step 1. Pour the milk into your slow cooker pot and add the cocoa powder and sugar.

Step 2. Whisk it well so it is all combined. Heat on high for 2 hours.

Step 3. Add the chopped dark chocolate to the pot and stir with a wooden spoon until it has melted.

Step 4. Make a smooth paste in a small bowl or mug using 8 teaspoons of milk and 4 teaspoons of cornflour, mixed well.

Step 5. Pour the cornflour mixture into the hot chocolate, then whisk well.

Step 6. Heat on high for 1 hour until thickened. Whisk it occasionally to prevent lumps. Once ready, transfer the hot chocolate to a jug and serve. Top with whipped cream and chocolate shavings.

Serving
If you like, add marshmallows, use flavoured chocolate such as chocolate orange, add a dash of your favourite liqueur – Baileys would be delicious, to make this slow cooker hot chocolate your own.
Why not try white hot chocolate – use squares of white chocolate as the base instead of cocoa powder, and flavour it with vanilla extract.
A Warming Winter Treat
It is definitely the weather now for a warming mug of hot chocolate to take the chill off. What better than to make a big batch of it in your slow cooker so you can ladle it out at your winter parties.
Now, I’ve made slow cooker hot chocolate before (see my boozy salted caramel version here) but this is an extra thick and creamy version for pure indulgence!
Curling up on the sofa with a mug of this is my idea of heaven. Lashings of whipped cream and chocolate shavings take this from an everyday hot chocolate to something else completely.

Hi, I have 2 questions! How big of a crockpot did you use? I need to make a bulk amount and need to figure out if I need a second. Also, when you say corn flour do you mean the yellow ground corn flour or the white finely ground cornstarch? Thank you!
bakingqueen74 says
Hi there, I made this in my 3.5 litre slow cooker. If you are in the US this is the equivalent to 3.5 quarts. Cornflour here in the UK means the white finely powdered stuff which you call cornstarch in the US, which is used as a thickener. Hope this helps
Jan Bennett says
Oh wow! You are amazing – Who knew you could make this in a slow cooker?!!
bakingqueen74 says
ah thanks Jan, yes hot chocolate is perfect in a slow cooker as you can keep it hot till you need it.
Angela says
This looks delicious and perfect for the wintery nights ahead.
Can all ingredients be added at once? Just wondering if i can all before heading out for a walk and then come home to this warm treat.
bakingqueen74 says
Thanks Angela!
I haven’t tried it that way but i think it will work still. I might well try that out this evening before going to see a firework display, so will update here and in the recipe.
Sammie says
Wow! Fantastic recipe for a delicious looking hot chocolate that I know all of us, here at home would love. I’m hoping to get a new slow cooker for my birthday or Christmas and will definitely be making this. X
Choclette says
This looks divine Lucy and just what I need now. I’m shivering from the cold and this would warm me up very nicely. I’ve had a few of the Italian style hot chocolates and I do rather like the luxurious thickness of them. Thanks for sharing with #WeShouldCocoa.
Bronya Seifert says
This really does look yummy….and with Baileys? Now that would just finish a cold evening off.
Claire Jessiman says
This would be absoluetly perfect for a Christmas soiree. Can I just put my straw straight into the slow cooker?!
bakingqueen74 says

Jane says
Oh blimey, that looks SO good I might just have to get up from this warm comfy sofa and go make some!
