First, use CFPARAM tag to set a default value:

<cfparam default="" name="FORM.SomeDateField">

Then use the CFQUERYPARAM tag and the NULL attribute on the date field:

<cfquery ...>
INSERT INTO SomeTable (SomeDateField)
        (<cfqueryparam cfsqltype="cf_sql_timestamp" null="#YesNoFormat(Trim(FORM.SomeDateField) EQ "")#" value="#FORM.SomeDateField#">)
</cfquery>

The cfqueryparam tags null attribute can be used to send a NULL value to the database, which is essentially a blank value as long as the field accepts null values.  The YesNoFormat function returns back a yes if the FORM.SomeDateField is blank and no if it contains data.
