Check your THEME.LIQUID for multiple places where the <TITLE></TITLE> tag appears. From looking at a page source, I would guess the SECOND instance is from Utra SEO.
First:
<title>Big Chocolate Cookies with White, Milk & Dark Chocolate</title>
Second:
<title>Big Chocolate Cookies with White, Milk & Dark Chocolate | Big Cookie | Homemade Cookies for Sale, Cookies For Delivery</title>
The Ultra SEO tag might actually get inserted via a {% include %}.
