Place a cast-iron skillet (10–12 inch) in the oven. Preheat to 425°F (220°C).
In a blender, combine eggs, flour, milk, melted butter, salt, and pepper. Blend until smooth and slightly frothy. Let rest 5 minutes.
Carefully remove hot skillet from oven, add 1 tbsp butter, and swirl to coat. Immediately pour batter into skillet.
Sprinkle evenly with cheddar cheese and bacon pieces.
Bake for 20–25 minutes until puffed and golden brown at the edges.
Sprinkle with parsley and chives. Optionally drizzle with honey or hot honey for a sweet-savory kick.
Slice and serve warm straight from the skillet.
