I've been given a recipe for a confection called "Mounds Cake" and I need your advice. It seems to me that it could be cloyingly sweet as written. Take a look at the recipe below and see if you would use sweetened coconut or switch to unsweetened. Also, it calls for chocolate chips and I wonder if I should substitute an equal measurement of chopped, semi-sweet or bittersweet chocolate. I'd like to make this something adults wouldn't mind eating.
1 White Cake with Pudding cake mix
2 cups sugar, divided
1½ cups milk, divided
1 14-oz. bag of shredded coconut
5 tablespoons unsalted butter
1 12-ounce bag of chocolate chips
1. Using a single 9 x 13 pan, bake cake mix according to package directions.
2. Ten minutes before the cake is ready to come out of the oven, heat the marshmallows, 1 cup of sugar and 1 cup of milk, stirring, until melted together. Stir in the shredded coconut.
3. As soon as the cake comes out of the oven, spread the marshmallow/coconut mixture on top and let cool for ½ hour.
4. Meanwhile, heat the remaining 1 cup of sugar, ½ cup of milk and the butter to a simmer; remove from heat and add the chocolate. Stir until melted. Top the cooled cake with chocolate mixture and let cool completely.
