Place Brie in a greased 9-in. square baking pan. Top and surround Brie with peaches. Bake at 350° for 10 minutes. Drizzle with 2 tablespoons honey. Broil 3-4 in. from the heat for 4-6 minutes or until edges of Brie are lightly browned.
Transfer Brie to a serving plate and spoon peaches over top. Drizzle with remaining honey and sprinkle with basil if desired. Serve with crackers.
