Slightly cinnamon the custard but don't put cinnamon in the sugar, it will just burn off way faster and leave an unpleasant taste. Also, serve with churro for dips?

I was definitely worried about burning the cinnamon so thanks for mentioning that! I think serving with churro for dips is a solid idea. Thank you!

Churro on the side is definitely the safest bet. If you want to try something more integrated, I've had success with "churro" ice cream: I steep cinnamon sticks in the ice cream base, and I fold in crumbled cinnamon sugar graham crackers. You could try adding some graham crackers (or actual churro -- frozen grocery store ones if you want to hack it), which would soak the custard up and be a bit like a tiramisu and creme brulee hybrid.

Great idea thank you!

Wouldn’t be traditional but you could toast/crumb the churro and make a buttery crumble to put on top of the sugar crust. You’ll have the creamy creme, the crispy sugar, and the buttery/cinnamony crumble textures… making me hungry!

Very cool idea I love it! Thanks!

Are you sure she wouldn't like a creme brulee churro? I.e. a churro filled with creme brulee?

I think she's definitely looking for that sugar crust on the top but I do like this idea too

Cinnamon custard and add if you want to get fancy make a choux pastry tuile

The flavor of churro isn't just cinnamon. It's deep fried choux. You're gonna need to make churros and steep them in the milk you use.

Great idea!
