Hi Prasunjeet,
I have created sample with master page. Please refer the below sample code.
Instead of Response.SetCookie use Response.Cookies.Add
SetCookie is used for Updating an existing cookie in the cookie collection.
Cookies.Add is used for Adding specific cookie to the cookie collection.
MasterPage.master

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

MasterPage.master.cs
public partial class MasterPage : System.Web.UI.MasterPage
{

{
}
protected void GetCookie(object sender, EventArgs e)
{
HttpCookie cookie = Request.Cookies["PdGuestID"];
if (cookie != null)
{
lblGetCookieValue.Text = Request.Cookies["PdGuestID"].Value;
}
}
}

{
HttpCookie cookie = new HttpCookie("PdGuestID");
cookie.Value = txtCookie.Text.Trim();
cookie.Expires = DateTime.Now.AddDays(30);
Response.Cookies.Add(cookie);
}
}
