How to grant execute on stored procedure?

 Normally when I create a stored procedure I use the following as a template of sort

Create procedure 
<@param1 , @param2 , etc..> 
as begin
 

end

Is there a way to include granting execute permission on only that stored procedure while I'm at it?

For instance like ...

Grant execute [User_Execute] 
... but only for this stored procedure?

I've seen some other similar questions but they seem to all refer to ALL of the stored procedures and not just one, nor have I seen one where you can specify permissions inside of the create procedure script. Even answers about how I can set permissions without the GUI for specific stored procedures would be welcome.
