Portion: Serves 8
3 large cinnamon bun, icing removed
4 cups milk
1 tbsp vanilla extract
1/4 cup sugar, + 2 tbsp for sprinkling
1/4 cup brown sugar
Let cinnamon buns dry overnight (or if in a hurry, chill in the fridge).
Preheat oven to 350 F.
Slice cinnamon buns across, creating 2 spiral-looking halves.
Butter a 9-by-13 inch baking pan and arrange slices into pan.
Heat milk and vanilla just to a simmer.
In a bowl whisk together sugars and eggs. Adding a little at a time, whisk milk into eggs until all is incorporated.
Pour over buns and press down to let mixture soak in. Sprinkle top of pudding with sugar.
Bake for 35-45 minutes, until centre of pudding springs back when pressed.
