Peach-Vanilla Cream Pops

Place sugar and 1/2 cup water in a small saucepan. Scrape in seeds from vanilla bean; add bean. Bring to a boil over high heat, stirring until sugar dissolves. Transfer syrup to a small bowl; chill. Discard vanilla bean. Purée syrup and peaches in a food processor until smooth. Set a fine-mesh strainer over a medium pitcher; strain, pressing on solids to extract about 2 1/4 cups purée. Whisk in remaining ingredients. Divide among molds. Cover; insert ice-pop sticks. Freeze until firm. Dip bottoms of molds into hot water for 20-30 seconds to loosen pops. Remove pops from molds and serve.
