I was unable to find anything resembling this quote in either German or English.
The closest quote is one from the Nurenberg rally in 1934:
> The cleverest trick used in propaganda against Germany during the war was to accuse Germany of what our enemies themselves were doing.
While this isn't proof that Goebbels didn't also say the quote in question, a complete lack of any sources at least indicates that someone may have loosely paraphrased him to get a more fitting quote.
The earliest date that the quote appeared on the internet seems to be in this relatively recent tweet from May 2015.
