Do following steps:

• Create new workflow using SharePoint designer & add Send an Email activity
• Specify values in To & Cc fields of Email compose box & save the worlkflow
  
• Open .xoml file of workflow & find BCC & CC values(BCC value should be null)
  
• Swap the values to CC & BCC & save the .xoml file
  
• Again open the Workflow with wizard, you will see CC value of Email activity is empty(null).
• Compile the rest of email body & finish the workflow compilation wizard.

Now email will be sent as BCC.
