The quest start location.
(If you don't want to go through the entire process the quest intends, just bring a pot of flour, a bucket of milk and an egg with you to complete the quest in seconds.)

To begin the quest, talk to the cook in the Lumbridge Castle's kitchen, which is on the ground floor. He tells you that it is Duke Horacio's birthday, and he is supposed to prepare a cake for the celebration, but he has forgotten to bring some of the ingredients required for the cake. Thus, he requires you to bring him a bucket of milk, an egg, and a pot of flour.

Note: A pot is found on the kitchen table, and a bucket is down in the cellar on a table.
Bucket of milk
Milking the prized cow
Milking a dairy cow.
You can get a bucket from the general store for 2 coins, or you can find one at various locations, including downstairs in the castle's cellar on a table. To obtain the milk, go to the Lumbridge cow field (east of Lumbridge, north of the entrance to the desert) and use the empty bucket on a dairy cow.

Egg
Where to find egg
The location for a quick egg, just north of Lumbridge.
To obtain an egg, go west of the cow field to the chicken coop and pick one up.

Pot of flour
To obtain a pot, buy one from the general store or get one for free from the table by the Cook in Lumbridge Castle. To fill it with flour, go north of Lumbridge and follow the road until you get to the mill. Collect the grain outside and go to the top floor, put the wheat in the hopper and then pull the lever. Back on the ground floor, use your pot to collect it from the bin.

Delivery
To wrap up, take the ingredients back to the cook in the Lumbridge Castle. Speak to him one last time to give him the ingredients.
