Preheat oven to 425° F.

In a blender, blend the eggs until bubbly. Next, add the flour, milk, sugar, and vanilla. Blend again until smooth.

Let sit for 15 minutes while you prepare your cast iron pan.

Add the butter to a 10-inch cast-iron pan and place it in the oven to let the butter melt. Keep a close eye on this so the butter does not burn.

Once the butter is melted, remove the pan and twirl it around so that the butter coats the side of the pan.

Add the batter to the preheated pan and place in the oven to bake for 15 minutes.

After 15 minutes, reduce the heat to 350° F and bake for another 15-18 minutes or until the sides are golden brown and the center is cooked through.

Remove and let cool for 5 minutes before adding any toppings. Topping options include fruit, nuts, syrup, whipped cream, powdered sugar, etc.
