Step 1

Preheat oven to 400°F. Grease a 6-cup popover pan or standard muffin tin with cooking spray.

Step 2

In a blender, combine the eggs, milk, butter, and salt in a blender until totally smooth. Add the flour and pulse several times, until just combined and just a few small lumps remain. Scrape down the sides of the jar if necessary.

Step 3

Pour the batter into the prepared pan, filling each cup about 2/3 way full.

Step 4

Bake for 25 minutes, then reduce the oven to 350°F for 10-15 more minutes, until the popovers are golden brown and crisp on the exterior and puffy.

Step 5

Remove from the oven and use a sharp knife to poke a small hole in each popover to let steam release. Cool in the pan for 5 minutes, then serve immediately.
