Heat your oven to 425°F (220°C). Toss your butter into a 9×13-inch pan and place it in the oven to melt while it preheats. This step sets up a crisp and buttery foundation.

Pop eggs, milk, flour, vanilla, and salt into a blender. Run it until the mix is smooth, with no lumps hanging around. This is key to making a puffy result.

When the butter in your pan is hot and bubbling, pull it out of the oven. Quickly pour in your blended batter. The edges will start setting up right away!

Slide the pan back into the hot oven. Let it bake for 22-27 minutes. The edges will creep up and turn a golden brown shade, while the middle puffs up.

Serve it immediately while the towering puff is fresh and dramatic. Top with sugar, maple syrup, or pile on berries and whipped cream—whatever excites you most.
