Preheat your oven to 350°F (175°C) and prepare a 9x9-inch baking pan by greasing it or lining it with parchment paper.

In a medium saucepan, combine the unsalted butter, granulated sugar, and unsweetened cocoa powder over low heat, stirring until melted together smoothly, about 5 minutes.

Remove from heat and let the mixture cool slightly, then whisk in the eggs one at a time until fully incorporated.

In a separate bowl, sift together the all-purpose flour and a pinch of salt. Gradually fold this mixture into the wet batter until just combined.

Pour the brownie batter into the prepared baking pan and bake for 25-30 minutes until a toothpick inserted comes out with moist crumbs.

Let the brownies cool in the pan for 10-15 minutes, then melt the white chocolate chips and drizzle over the brownies in a spider web pattern.
