How do you make angel delight?

I tried making the strawberry one the other day but it was like yogurt, I thought it's supposed to be a mousse. Its probably because I only added a cup of milk not 300ml and whisked it for too long and left in fridge over night because I checked it after 5 mins but it didn't look any different so I left over night, next day there was no change it turned out like creamy yogurt not a mousse although it tasted good I was disappointed with the texture. I brought the chocolate one too but I don't want to mess it up. I don't want to have a creamy chocolate yogurt I want a chocolate mousse 😤

i usually put a bit less milk than they say because i want it thicker. also whisk it so its airy/moussey

Less milk

Caramel is my favourite

Thanks, I'll add less milk next time!

I think it is called butterscotch
