Melt ½ cup of unsalted butter and 1 cup of semi-sweet chocolate chips in a medium saucepan over low heat. Stir frequently until smooth, about 5 minutes. Remove from heat and cool slightly.

In a large mixing bowl, combine the cooled chocolate mixture with 1 cup of granulated sugar. Whisk in 2 large eggs, one at a time, and stir in 1 teaspoon of vanilla extract until glossy and blended.

In a separate bowl, sift together 1 cup of all-purpose flour, ⅓ cup of unsweetened cocoa powder, and ¼ teaspoon of salt. Gently fold dry ingredients into the wet ingredients until just combined.

Grease an 8x8-inch baking dish. Pour in brownie batter and smooth the top. Preheat oven to 350°F (175°C).

Bake in the preheated oven for 20 to 25 minutes or until a toothpick comes out with a few moist crumbs. Allow cooling for 10–15 minutes in the dish before transferring to a wire rack.

Once cooled, spread a smooth layer of chocolate frosting over the brownies. Use chocolate chips and candies to decorate Chewbacca's features.

Slice brownies into squares or rectangles to serve, making about 12 servings. Enjoy!
