First time cooking gluten free: Please send your favourite Christmas cookie recipes!

Hello! I’m baking Christmas cookies for my boyfriend’s grandparents and they are gluten intolerant (not completely gluten free). I’ve never baked anything gluten free before so I’d love any tried-and-true cookie recipes that you enjoy! I’d love to make a large assortment of cookies any additional tips and tricks you have will be greatly appreciated! ❤️
