Bring milk to a boil together with seeded vanilla pod. Melt butter in this mix and reserve.

Mix sugar, flour and eggs in a large mixing bowl. Add warm milk little by little. You will get a dough looking a bit like a pancake dough. Add green matcha tea.

Refrigerate at least one hour and up to 12 hours.

Preheat oven to 250°C. Butter molds with the melted butter using a kitchen brush.

Fill molds no more than 3/4 because your canneles will rise.

Bake for 10 minutes. Low temperature to 180°C and bake for another 50 minutes.
