This is a miniature dollhouse, probably 1/6 scale (I didn't take accurate measurements for this) wedding cake. This was originally made years ago in a YouTube tutorial based on a real cake I saw online. Originally the flowers were, of course, beautiful and in perfect shape, but over the years they have broken off. I have taken detailed pictures of the broken flowers which are aligned on the sides of the cake and the one that is pretty much crumbled off the top. It is also glued down to this misshapen blue wooden board. Years back when I made this, I didn't have a proper round wooden board and had to craft this out of something else, I believe. I have discounted it by $20 since the flowers are now damaged in case someone wants to buy it still. It would also make a cute cake topper.

Perhaps your doll is a baker or maybe likes to bake but isn't super good at it and his/her cake came out pretty good but his/her decorating skills is lacking because they are clumsy. If you would like more accurate measurements besides my fingers in the video and photos just message me and I will take them for you.
