Preparation

  1. In a food processor, process the butter, sugar, cocoa powder and salt until smooth, about 30 seconds, scraping the sides of the bowl as needed. 2. Add the corn syrup and vanilla extract and process until just combined, 5 to 10 seconds. 3. Scrape the sides of the bowl, then add the chocolate and pulse until smooth and creamy, 10 to 15 one-second pulses.
