Preheat the oven to 350 degrees F. Grease a 9-by-12-inch baking pan with butter.
Combine the oats and sugar in a medium bowl, then pour in the milk.
Add the vanilla seeds, cinnamon, nutmeg, salt and baking powder.
Next comes the melted butter and the egg.
Then just stir it all together into a big delicious oaty mess of wonder.
Plop the mixture into the prepared pan and spread it out.
Bake for 30 minutes, until set.
Cut into squares while still warm. Serve with cream, brown sugar and berries.
To scrape the vanilla bean, split the pod lengthwise with a small paring knife and use the back of the knife to scrape out all the vanilla caviar (the seeds). (Tip: Put the empty pod in a container of sugar. It will infuse the sugar and make it a miracle!)
