Glucose risk
Hot chocolate delivers 16-30g of carbohydrate per mug, mostly from added sugar and lactose. The cocoa itself is low GI, but the sugar content drives a moderate blood sugar response.
Processing level
Pure cocoa powder is NOVA 1. Drinking chocolate (cocoa + sugar) is NOVA 3. Instant hot chocolate sachets with dried milk, flavourings, and emulsifiers are NOVA 4.

What to watch for when shopping
Most instant hot chocolate powders are NOVA 4 - loaded with sugar (50-60% of the product), skimmed milk powder, and emulsifiers. A 200ml cup of instant hot chocolate has 100-150 kcal, mostly from sugar. Making your own with real cocoa powder and milk keeps it at NOVA 1-2 with more control over sweetness.
