Do you sell this cake? No, just for fun Share a little about the materials, processes, and techniques used to create this cake Mini Tier with surprise heart inside, thanks to Amanda Rettke's Decorating from the Inside Out tutorial. This is a "test" cake for a wedding--needed to make sure I knew what I was doing. I used cake and icing mixture for the heart. I was very happy with the outcome, so the real cake is a go. What are you most proud of? The heart turned out even better than I expected.
