Unlocking the secret to glossy, crackly brownie tops

A crackly brownie top is a desired characteristic for many brownie lovers. Here's a recipe to make brownies with a deliciously crackly top:

Ingredients:

• 1 cup unsalted butter, melted
• 2 cups granulated sugar
• 1 1/4 cups unsweetened cocoa powder
• 1 teaspoon vanilla extract
• 1/2 teaspoon salt
• 4 large eggs
• 1 cup all-purpose flour

Instructions:

1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
2. In a large mixing bowl, whisk together the melted butter, granulated sugar, cocoa powder, vanilla extract, and salt until well combined.
3. Add the eggs to the bowl and whisk again until the mixture is smooth and glossy.
4. Gradually add the all-purpose flour to the bowl, whisking until just combined.
5. Pour the batter into the greased baking pan and spread it out evenly.
6. Bake the brownies for 25-30 minutes, or until the top is shiny and crackly and a toothpick inserted into the center of the brownies comes out with a few moist crumbs attached.
7. Remove the pan from the oven and let the brownies cool for at least 10-15 minutes before slicing and serving.
8. Store any leftover brownies in an airtight container at room temperature for up to 3-4 days.
