Preheat the oven to 425°F (220°C) and place a cast-iron skillet inside to heat.

In a bowl, whisk together eggs, flour, milk, melted butter, salt, and black pepper until smooth. Let the batter rest for 5 minutes.

Remove the hot skillet, add melted butter, and swirl to coat.

Pour in the batter, then top with cheddar cheese and crumbled bacon.

Bake for 20-25 minutes until puffed and golden brown.

Let cool slightly, garnish with chopped herbs, and optionally drizzle with honey before serving.
