Spray a 12-cup nonstick muffin pan with cooking spray.
Whisk eggs until frothy in a medium bowl. Whisk in buttermilk, vanilla, sugar, and salt.
Whisk flour into batter. Gently fold in blackberries.
Divide batter evenly among muffin cups. Bake for 30 to 35 minutes, or until popovers are golden. Remove pan from oven, and immediately poke a small hole or cut a small slit in the center of each popover to release steam.
Serve popovers fresh and warm.
*If you don’t have buttermilk on hand, you can easily make your own:
Add 1 tablespoon of lemon juice to 1 cup of whole milk.
Let mixture stand for 10 minutes and use as directed.
