In a large pot over medium high heat add the beer, 1 cup sugar, vanilla, cloves. Bring to a simmer. Add the pears and enough hot water so that pears float. Cook until the pears are fork tender, 15-20 minutes.
In a separate pot add the chocolate stout, corn syrup, remaining 1/3 cup sugar and cocoa powder, bring to a simmer. Cook, stirring occasionally, until thickened, about 8 minutes.
Drain the pears and add to small bowls. Drizzle with chocolate sauce, sprinkle with chopped Moose Munch.
Notes
*For the poaching liquid you want a malty beer, but not a dark beer (dark beers may change the color of the pears). Look for a Belgian ale, brown ale or amber ale.
*You can also use regular caramel corn in place of Moose Munch.
