These gluten free popovers are perfectly puffed, golden, and crisp on the outside with a hollow, airy center. They're a showstopper worth making for any occasion.
Preheat oven to 450F and place a 6-cup popover pan or a muffin tin in the oven while it preheats. In a blender, combine eggs, milk, gluten free flour, salt, and melted butter. Blend until completely smooth, about 30 seconds.
Let the batter rest at room temperature for 15 minutes while the oven and pan heat.
Carefully remove the hot pan from the oven and generously grease each cup with butter or cooking spray. Divide the batter evenly among the cups, filling each about two-thirds full.
Bake at 450F for 15 minutes, then without opening the oven door, reduce the temperature to 350F and bake for 15 to 18 minutes more until the popovers are deeply golden, puffed, and crisp.
Remove from oven and immediately poke a small hole in the side of each popover with a toothpick to release steam. Serve hot with softened butter and your favorite jam.
