Preheat oven to 350°. In a large bowl, cream first four ingredients until light and fluffy. Mix juice and champagne. Add flour to creamed mixture alternately with juice mixture, beating well after each addition.
Cut a small hole in the tip of a pastry bag or in a corner of a food-safe plastic bag; insert a #1M star tip. Transfer dough to bag; pipe 2-in. circles 2 in. apart onto parchment paper-lined baking sheets.
Bake until edges are set, 10-12 minutes. Cool on pan 5 minutes. Remove to wire racks to cool.
Preheat oven to 325°. In a large ovenproof skillet over medium high heat, heat olive oil. Add chicken skin side-down and cook until the skin is golden and crispy, about 4 minutes. Remove chicken from heat and place on plate, skin side-up.
Melt butter in the same skillet then add cranberries, vinegar, garlic, brown sugar, and orange zest. Return chicken to skillet and scatter herbs all around. Simmer until the liquid begins to thicken and the cranberries start to soften, 5 to 10 minutes.
Transfer to oven and cook until the chicken thighs are cooked through, 18 to 25 minutes more.
Preheat oven to 350°. In a large bowl, whisk flour, sugar, orange zest and baking powder. In another bowl, whisk eggs, milk and oil until blended. Add to flour mixture; stir just until moistened.
Shape into a 6-in. round loaf on a greased baking sheet. Brush top with egg yolk; sprinkle with coarse sugar. Bake 45-50 minutes or until a toothpick inserted in center comes out clean. Cover top loosely with foil during the last 10 minutes if needed to prevent overbrowning. Remove from pan to a wire rack; serve warm.
