With baking dish in the oven preheat to 400 F (I used a square 8×8 pyrex)
Blend eggs, milk, flour, and salt until smooth.
Place butter into hot dish and swirl around so it’s melted and sizzling.
Pour in blended batter.
Bake uncovered for 20 minutes at 400F.
Pull out of the oven, squeal with delight, post picture bedhead and all on instagram ;) oh I mean eat it and enjoy the deliciousness that was so ridiculously easy you have no idea why you didn’t try to make them sooner. Try it with a squeeze of lemon and some powdered sugar yum!
