Preheat your oven to 375°F (190°C).

Sprinkle both sides of the chicken breasts generously with salt and black pepper.

In a large oven-safe skillet, heat olive oil over medium-high heat and sear the chicken breasts for about 3–4 minutes on each side until golden-brown.

Lower the skillet's heat and add the softened unsalted butter, allowing it to melt completely.

Stir in honey, ground cinnamon, ground nutmeg, and vanilla extract into the melted butter until blended and slightly caramelized.

Return the browned chicken breasts to the skillet and drizzle the buttery mixture over them.

Transfer the skillet to the preheated oven and roast for 20–25 minutes until the chicken reaches 165°F (74°C).

Baste the chicken with the bubbling butter sauce halfway through cooking.

Once cooked, remove the skillet from the oven and let the chicken rest for a few minutes.

Sprinkle freshly chopped cilantro over the dish and serve hot.
