Blueberry Oven Pancake

As a young child, every year, my family would travel to San Diego to visit Grandma and Grandpa. Every year we would see the same sites (I can't tell you how many times I've been to the zoo, Sea World, and Balboa Park) and eat at the same restaurants. One of these restaurants was the T-Bird Diner, an old-school replication of a 1950s Diner, complete with servers in poodle skirts and paper hats. I loved that place, if even just for the thick shakes.
Another of these over-visited restaurants was what I think is part of a California chain, called Pancake House (which is, somehow, different than IHOP). I remember always being intrigued by their giant pancakes that were not flat and floppy but puffy and light. This style of pancake, my brother informed me, is very popular in the Netherlands--it's actually known as a dutch baby, but my have more German roots, and be a descendant of Yorkshire pudding.
Anyway, I really like the recipe I made, which was super simple, faster than making batches upon batches of griddle cakes, and super tasty! For some reason, I always have a thing for casseroles, or just dishes that are baked, all at once, all servings originating from the same vessel. I really don't know why- I am just drawn to these meant-to-be communal dishes! This blueberry oven pancakes makes the cut as such. I hope you do enjoy! And serve with maple syrup or powdered sugar, if you've got it on hand.

Blueberry Oven Pancake

1 T butter
4 eggs
1 c milk
1 c flour of your choice (unbleached or wheat)
1 t vanilla
pinch salt
1 1/2 c blueberries (frozen will do just fine)

1. Preheat oven to 450 with cast-iron skillet in oven.
2. Mix eggs, milk, vanilla with a whisk.
3. Add flour, salt, mix well.
4. Remove skillet from oven, and spread your butter all over it, bottom and sides, before it all melts!
5. Pour in batter.
6. Sprinkle blueberries on top.
7. Bake at 450 for 15 minutes, then lower heat without opening oven, to 350, for 8 minutes.
Be sure to use oven mitts to remove this bad boy- I've had nasty skillet handle burns before. That thing gets HOTT!
