Optional Toppings: Powdered sugarberries, maple syrup, fresh squeezed lemon juice, etc.
Preheat oven to 450 degrees.
In a medium bowl, add the eggs, milk, sugar, salt & vanilla.Whisk to fully combine. Add the flour, and stir with the whisk to just combine. Be sure not to overmix the batter.
Place the butter in a 10-inch oven safe skillet or cast iron skillet. Put the skillet in the oven to melt the butter. Once the butter is melted, remove from the oven. Pour the batter over the melted butter. Place the skillet back in the oven for 12-15 minutes or until the edges are brown. (The pancake will puff up in the oven, but it will fall when it is removed from the oven.)
Sprinkle your favorite toppings over the top & enjoy!
