Sadly you will have to wait till Veliousbefore you can get to 200 baking.
If you search there were a good number of threads about both this and breweing.
Don't quote me on this but I think you should be able to get to around 154:
Birthday cake:
Winter Chocolate, Frosting, Clump of Dough. cake round, spit/oven 2 >154
Wedding cake:
white chocolate, frosting, clump of dough cake round, spit/oven 2 >154
Once Velious is released you can make dragon steaks or pixie powder cinnesticks to get to 200.
