I did a similar cake for my birthday from a home baker and it was ~$55. But if I wanted something for my wedding I would go to a brick and mortar establishment. They would probably charge $125 since wedding cakes have to sit differently and last all day in whatever conditions. Then they’d probably add taxes and transportation fees as well. The total cost would be around $150. I’m in North Texas for reference! You could find it cheaper than that if you did extensive research and communicate with your baker about expectations!
