Creating Gruyère and Chive Savory Madeleines is a straightforward process. Follow these steps to bake your own batch of these delectable mini cakes:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C). Grease your madeleine pan with butter or non-stick spray to ensure easy release.
2. Prepare the Dry Ingredients: In a medium-sized bowl, whisk together the flour, baking powder, salt, and black pepper until well combined.
3. Beat the Eggs: In a separate large bowl, beat the eggs until they are pale and frothy. This should take about 3-4 minutes of mixing.
4. Incorporate the Butter and Milk: Gradually add the melted butter and milk to the beaten eggs, mixing continuously to achieve a smooth and consistent batter.
5. Combine with Dry Ingredients: Carefully fold the dry ingredients into the wet mixture, ensuring no lumps remain. Be cautious not to overmix.
6. Add Cheese and Chives: Gently fold in the grated Gruyère cheese and chopped chives, distributing them evenly throughout the batter.
7. Fill the Molds: Using a spoon or piping bag, fill each cavity of the madeleine pan with batter, leaving a small space at the top to allow for expansion.
8. Bake: Place the pan in the preheated oven and bake for 10-12 minutes, or until the madeleines are golden brown and spring back when lightly touched.
9. Cool and Serve: Once baked, remove the madeleines from the oven and allow them to cool in the pan for a few minutes before transferring to a wire rack to cool completely.
