Preheat the oven to 350°F (175°C). Grease a baking pan.

In a mixing bowl, combine melted butter and sugar. Mix well.

Add eggs and vanilla extract, whisking until smooth.

In another bowl, mix cocoa powder, flour, salt, and baking powder.

Gradually add the dry ingredients to the wet mixture, stirring until combined.

Pour the batter into the prepared baking pan and spread evenly.

Bake for 25-30 minutes or until a toothpick comes out clean.

Allow brownies to cool completely before decorating.

Melt the white chocolate chips in the microwave, stirring until smooth.

Transfer the melted chocolate to a piping bag.

Pipe the melted chocolate over the cooled brownies in a crisscross pattern to resemble mummy bandages.

Place candy eyes on each brownie to complete the mummy look.

Let the chocolate set before serving.
