Ingredients

½ cup (113 g) unsalted butter, melted and slightly cooled

1 cup (200 g) granulated sugar

2 large eggs, room temperature

1 tsp pure vanilla extract

½ cup (63 g) all-purpose flour, spooned and leveled

⅓ cup (30 g) unsweetened natural cocoa powder (not Dutch-processed—its slight acidity enhances fudginess)

¼ tsp baking powder

¼ tsp fine sea salt

Optional flourish: Flaky sea salt for sprinkling before baking
