Preheat oven to 350°F (175°C) and line a 9x13-inch pan with parchment paper.

Melt 2 cups of unsalted butter in a medium saucepan over low heat. Whisk in 2 cups of granulated sugar until shiny. Cool slightly, then add 4 large eggs and 1 tsp vanilla extract, beating until thick and glossy.

Sift together 1 cup of all-purpose flour, 1 cup of unsweetened cocoa powder, ½ tsp baking powder, and ¼ tsp salt. Fold this dry mixture into the wet batter gently.

Pour the batter into the prepared pan and bake for 30 to 35 minutes, checking for doneness with a toothpick.

Once cooled, cut brownies into squares. Melt candy melts and drizzle over brownies, mimicking ribbons. Add mini candy bows and sprinkles.

Allow decorations to set before serving or packaging in gift boxes.
