I am searching for a tried and tested Thai Tea recipe. Would anyone have a recipe that they would be willing to share? TIA

Do you mean Chai Tea?

No I do mean Thai Tea. I have seen one on chockylit blog but this uses thai tea syrup, I was actually looking for something different

Here have the Thai tea recipe http://www.thaiteaset.com/
This is not a Chai Tea, this thai tea is called Cha Yen.

What is the difference between Chai Tea and Cha Yen? Chai Tea and Cha Yen are the Thai Tea isn't it?

Chai tea is black tea with spices and milk.

Cha Yen (Thai tea) is black or red tea with milk, no spices, served cold. Yen means cold in Thai. Cha means tea.

Cha Yen is made with strong black, red or a combination of red and black tea sweetened with condensed milk. The milk is what gives it it's characteristic look and flavor.

Are you asking about a cake recipe? They sell instant thai tea. I assume you could add it to the batter as flavoring. The instant (bought at an asian grocery) is the only kind I've found to taste like thai tea at thai restaurants. Most recipes I've tried just don't taste right.
