Preheat oven to 425ºF (218ºC).

Grease a pizza pan well with oil or butter.

In a large bowl, whisk together oats, flour, baking powder, and sea salt until well blended.

Pour in water and melted butter and mix with a sturdy mixing spoon.

The dough should be thick and form a ball in the middle of the bowl.

With greased hands, pick up the dough and form it into a ball.

Place the ball of dough on the pizza pan and flatten it out using your palms. Add more oil to your hands as needed to prevent sticking.

Once you have a nice even layer, bake the crust on the middle rack for 12-13 minutes.

Remove the crust when it's lightly browned. It's always right at 12 minutes for me.

Add toppings and return to the oven for another 12-13 minutes.

Remove and add any remaining toppings (if using prosciutto and/or fresh herbs add them after baking).

Let it sit in the pan for about a minute, then either cut in the pan with a pizza slicer or remove to a cutting board to cut it with a knife.

Enjoy!
