I did a chocolate cake made from scratch, and a homemade orange frosting/ cake filling. For the hearts I just purchased some of the Wilton Melting Wafers in Light Cocoa and piped out hearts with different designs in the middle.
Orange Frosting Recipe
4 T Softened Butter
1/2-1 t Vanilla
3 cups Powdered Sugar
3-4 T Fresh Orange Juice
Zest of 1 Orange
Mix it all together with an electric mixer. you may have to add more or less juice to get the desired consistency. I had to make two batches of frosting to cover two- nine inch cake rounds, and fill in between. I wouldn't suggest automatically doubling the recipe as it may dilute the intensity of the orange flavor. 6-8 T of orange juice may be too much in one batch, and by scaling it back you would lose some of that orange-y goodness. Maybe it wouldn't, I don't know.
