Preheat your oven to 350 degrees.
Melt your ½ cup of butter.
Rinse and dry off your cherries.
In a large mixing bowl combine the cake mix, chopped cherries, melted butter, 3 eggs, ½ cup milk and ½ cup cherry juice.
Spray two 8 or 9 inch cake pans with non-stick spray.
Divide the cake batter between the 2 pans.
Bake the cakes for 22-25 minutes or until a toothpick inserted in the middle comes out clean.
Let the cakes cool slightly and then remove from the pans onto a wire rack to cool completely.
Once the cakes are completely cooled you can make your frosting.
In a large bowl combine your softened butter, powdered sugar, 6 tablespoons milk and 2 tablespoons of maraschino cherry juice.
Place one cake on your cake plate and top with a good amount of the frosting and spread out.
Top with the other cake.
Frost the cake completely.
Using a piping bag with a star tip pipe frosting around the top and bottom edge of the cake.
Garnish with reserved cherries.
Slice and serve!
