1. Talk to the Cook on the first floor of the Lumbridge Castle and ask him what is wrong. He will explain to you about how he forgot to buy the ingredients for a cake he needs to make for Duke Horacio's birthday. He asks if you could help fetch the items for him. Agree to help him. There are three ingredients you have to find: Extra fine flour, Top-quality milk, and a Super large egg.
   
   
   
   
2. Pick up the Pot from the table in the room of with the Cook. Leave Lumbridge Castle and head northwest following the path until you come to a field full of wheat with a windmill next to it. Go into the field and click on one of the wheat stalk to pick some Grain.
   
   
   
   
3. Grind up the Grain into flour. Go inside windmill and talk to Millie Miller. Take the stairs up to the top floor. Once there use your grain with the hopper and operate the controls. Head back down to the first floor and use your Pot with the freshly ground Extra fine flour.
   
   
   
   
4. Now it is time to obtain the Super large egg. These eggs can be picked up at Fred the Farmer's farm to the south of the mill and the farm to the east across the bridge OR follow the path south east until you come across a chicken coop If there isn't one, you will have to wait for a little while for it to respawn.
   
   
   
   
5. Head east along the path and across the bridge to the other side of the river, and continue north on the path until you come to a large, fenced-off enclosure with many cows inside. Open the gate and find a Dairy cow. Right click on the Prized dairy cow and select 'Milk' to obtain some Top-quality milk.
   
   
   
   
6. Now that you have gathered all three ingredients needed, head back to the Cook in Lumbridge Castle and talk to him to get your reward.
