Ooooo! Gorgeous! I'm a Great British Bakeoff fan too! That's a great Christmas Tear-n-Share!
Made a vegetarian loaf recipe from one contest finalist on the Bakeoff show
They had a Florentine baking episode but it wasn't gluten-free so I improvised & used Almond & Coconut flour instead. Not as attractive as the show cookies but they were crispy, chocolatey, & yummy! I love thin warm crispy cookies.
