Ingredients:

• Dark chocolate, 200g (chopped)
• Unsalted butter, 150g
• Granulated sugar, 200g
• Eggs, 3 large
• All-purpose flour, 100g
• Cocoa powder, 30g
• Orange zest, from 1 large orange
• Ground cinnamon, 1 tsp
• Ground ginger, ½ tsp
• Ground nutmeg, ¼ tsp
• Salt, a pinch
• Optional: Chopped walnuts or pecans, ½ cup; white chocolate chips for drizzling

Instructions:

1. Preheat Oven and Prepare Pan:
   • Preheat your oven to 180°C (350°F).
   • Line an 8-inch square baking pan with parchment paper.
2. Melt Chocolate and Butter:
   • In a heatproof bowl, melt the chocolate and butter together. You can do this over a pot of simmering water (double boiler) or in the microwave in short bursts, stirring frequently.
3. Mix Wet Ingredients:
   • In a separate bowl, whisk together the eggs and granulated sugar until well combined.
   • Mix in the melted chocolate and butter.
   • Stir in the orange zest.
4. Add Dry Ingredients:
   • Sift in the flour, cocoa powder, cinnamon, ginger, nutmeg, and a pinch of salt. Fold gently until just combined.
   • If using, stir in the chopped nuts.
5. Bake:
   • Pour the batter into the prepared pan and smooth the top.
   • Bake for 20-25 minutes, or until the top is set and a toothpick inserted into the center comes out with a few moist crumbs.
6. Optional White Chocolate Drizzle:
   • Once the brownies are cooled, melt white chocolate and drizzle over the top for a festive look.
