Spray the pan you are using for brownies.
Prepare brownies as directed on the package.
Make Coconut Filling by combining 2 1/2 cups sweetened coconut with 1/2 cup heavy cream, mixing until coconut is completely moistened.
Make Ganache by chopping up semisweet chocolate and putting it into a medium bowl. Heat heavy cream to a soft boil and pour onto chocolate, mixing together until smooth and creamy.
Bake brownies and let cool.
Once brownies are cool, press coconut filling on top of them, distributing it evenly.
Put pan in freezer to set the coconut.
Remove brownies from pan, cutting if necessary.
Drizzle chocolate ganache on brownies.
Decorate with coconut sprinkles and almond slivers.
Chill before serving.
Serve and Enjoy!
