Classic popovers are moist on the inside, crispy on the outside. We've added a crunchy top layer of Parmesan. If you don't have the cheese on hand, simply omit it for a more traditional version.
1 cup 2% reduced-fat milk
2 large egg whites
1 large egg
2.75 ounces all-purpose flour (about 2/3 cup)
1.5 ounces whole wheat flour (about 1/3 cup)
1/4 teaspoon salt
2 teaspoons butter, melted
1/4 cup (1 ounce) grated fresh Parmesan cheese
How to Make It
Combine first 3 ingredients in a medium bowl, stirring with a whisk until blended. Let stand 30 minutes.
Preheat oven to 375°.
Weigh or lightly spoon flours into dry measuring cups; level with a knife. Combine flours and salt, stirring with a whisk. Gradually add flour mixture to milk mixture, stirring well with a whisk.
Coat 6 popover cups with cooking spray; brush butter evenly among cups to coat. Place popover cups in a 375° oven for 5 minutes. Divide batter evenly among prepared popover cups. Sprinkle evenly with cheese. Bake at 375° for 40 minutes or until golden. Serve immediately.
