SQL Server 2012 :: Missing Months In A GROUP BY Statement

I am trying to get a count by product, month, year even if there are is no record for that particular month.

Current outcome:
Product Month Year Count
XYZ January 2014 20
XYZ February 2014 14
XYZ April 2014 34
...

Desired outcome:
Product Month Year Count
XYZ January 2014 20
XYZ February 2014 14
XYZ March 2014 0
XYZ April 2014 34
...

The join statement is simple:
Select Product, Month, Year, Count(*) As Count
From dbo.Products
Group By Product, Month, Year

I have also tried the following code and left joining it with my main query but the product is left out as is seen:

DECLARE @Start DATETIME, @End DATETIME;
SELECT @StartDate = '20140101', @EndDate = '20141231';
WITH dt(dt) AS
(
SELECT DATEADD(MONTH, n, DATEADD(MONTH, DATEDIFF(MONTH, 0, @Start), 0))
FROM ( SELECT TOP (DATEDIFF(MONTH, @Start, @End) + 1)
n = ROW_NUMBER() OVER (ORDER BY [object_id]) - 1
FROM sys.all_objects ORDER BY [object_id] ) AS n
)

2nd attempt:
Product Month Year Count
XYZ January 2014 20
XYZ February 2014 14
NULL March 2014 0
XYZ April 2014 34
...

What I want is this (as is shown above). Is this possible?

Desired outcome:
Product Month Year Count
XYZ January 2014 20
XYZ February 2014 14
XYZ March 2014 0
XYZ April 2014 34
