Jalapeno Cheddar Popovers



3 large eggs, at room temperature
1 cup all-purpose flour
1 cup milk, at room temperature
3 tablespoons butter, melted
1/2 teaspoon kosher salt
1/4 cup (1 oz.) shredded sharp Cheddar cheese
1 tablespoon minced seeded jalapeno pepper (about 1 pepper)
Vegetable cooking spray

Preheat oven to 450. Process first 5 ingredients in a blender 15 seconds or until smooth. Stir in cheese and jalapeno, and let stand 30 minutes. Lightly grease a 12-cup muffin pan with cooking spray; place in a jelly-roll pan, and heat in oven 2 minutes. Spoon batter into prepared muffin pan, filling halfway. Bake 15 minutes. Reduce oven temperature to 375, and bake 8 to 12 minutes or until puffed and golden brown.
