2 Tbsp butter
1 cup milk
1 cup all-purpose flour
1 tsp vanilla extract
Preheat the oven to 400 degrees Fahrenheit, or 375 if you are using a glass pan. Place the butter in a 13"x 9" pan and put it in the oven to melt the butter and warm the pan. Remove from the oven when the butter is melted and tilt the pan to cover the bottom with the melted butter. While the butter is melting, place the flour in a medium bowl and add the milk, whisking it together until smooth. Whisk in the vanilla, and then the eggs, one at a time, blending completely after each addition.
Carefully remove the pan from the oven if you haven't already, and pour the batter into the pan. Place it in the oven and bake for 20 minutes.
The kids love to see the weird proportions this thing takes on as it puffs up.
Even more fun is watching it deflate. Anyway, cut it into squares and serve with powdered sugar, syrup, fruit or whatever pleases you. And there you have it.
