I am going to Ascot this week and need to take a dessert. I am driving there and live 90 mins away. I will arrive at about 11am and we will eat at about 12.30pm so it needs to be something that will be easy to transport and will still look and taste great after 3 hours wait, but can use a cool box. I need to make it the day before as I'm working late and first thing on the day of the picnic.
No allergies to be mindful of.
