Meanwhile, combine the remaining beer, the brown sugar, corn syrup, cream and butter in a large saucepan. Bring to a boil over medium-high heat and cook, stirring occasionally, until a candy thermometer registers 235, 10 to 12 minutes. Remove from the heat and stir in the beer syrup and pretzels. Spread in the prepared dish and chill until firm, 45 minutes to 1 hour. Cut into pieces.
