If we've learnt anything, it's that everyone can bake if they put their mind to it. Don't fear the soggy bottom!In fact, ring-shaped cakes are a symbol in many cultures of coming full circle, which make them timely for Twixmas. Many hide a coin or candy within the cake, as a symbol of good luck for whoever finds it! 3. Do a massive puzzle.

And equally fun to do with friends and family too! 4. Swap roles for a day.

But it could be a fun project to help them "cook" a meal for the full family. (With your guidance, of course.) 5. Do something retro...like go to the library. Michael D Beckwith / Public Domain / Via flic.kr Remember libraries? We jest – of course you do! But we're willing to bet that's a been a while since you've visited. They're a wonderful day out and much better than whatever's on the TV, that's for sure. 6. Find the positives in 2016.

So why not spend a few hours with the kids going through photos and picking out your highlights?(It's a good way to prepare yourself for the next one!) 7. Have an afternoon tea party.

It's about time you treated yourself to tea like the Queen takes it! You could bake scones, make finger sandwiches, and even break out the fine china! 8. Find a way to give back.

Or even just donate your time. Massonstock / Getty Images A good place to start is here! A few hours here and there can go a long way. 12. Make up for the lack of snow by going skiing! View this photo on Instagram instagram.com There's a surprising amount of dry ski slopes all around Britain, as well as a few snow centres, and they all cost significantly less than it would to get over to the French Alps. 13. Find out if it really will blend. Retales Botijero / Getty Images - NEEDS DOWNLOADING / Via gettyimages.co.uk Kids love to make a racket. Meanwhile, odds are that the blender in the cupboard doesn't get nearly as much use as you'd like. (They never do!)So one idea is to spend an afternoon bringing those two things together. The children get to experiment, while you get to slip in some of their five-a-day for good measure! 14. Go and check out your nearest National Trust site.

That includes historic houses, castles, ancient monuments, gardens, parks, nature reserves, pubs, inns, villages, and lots of things we're likely forgetting. 15. Make a dish that'll bring you some luck in the New Year. Bhofack2 / Getty Images All around the world, people have various traditions and superstitions designed to bring them prosperity and joy in the year ahead. For example, in the souther states of America, they eat a dish called Hoppin' John, made of pork, rice, and peas, to ensure good fortune in the upcoming year. They also have a saying: "Peas for pennies, greens for dollars, and cornbread for gold". In fact, collard greens are supposed to be worth $1,000 per bite, so maybe run that one by the kids!
