Preheat the oven to 200C and grease a large baking dish.
Cut the panettone into slices.
Place into the greased dish and slosh over some Amaretto (how much is up to you!)
Stir a little Amaretto into the custard and then pour that over the panettone slices.
Sprinkle with flaked almonds and place in the oven to heat through and brown on the top, 20-30 minutes, but keep an eye on it - you don't want it to burn.
Enjoy the easiest, decadent dessert ever on its own, or for more indulgence, with cream!
