Easiest and cheapest way to level up baking skill is Jord Meat Pies. Usually jord meats are pretty reasonable and you don't need to get other ingredients that must be bought or foraged. Another cheap option is to make cheesy casseroles. Go to Jaggedpine and go crazy killing anacondas or griffons, or just buy vegetables and use them for Cheesy Veg. casserole. Got my cleric to grandmaster for very little money.
