What is an impossible tart?
An impossible tart is so named because it seems impossible that one bowl of batter baked in the oven can separate into three distinct layers.
But it’s true. You just mix all the ingredients in one bowl and pop it in the oven. And what you end up with is a tart with a layer of soft pastry at the bottom, followed by a layer of custard, and topped off with a thin cake-type layer.
Some people call impossible tarts magic cakes. And with the magic season (aka Christmas) fast approaching, I thought it appropriate to share my impossible Christmas tart with you.
If this isn’t quite what you are looking for, why not give this easy coconut tart a try. It’s based on the same principle – a one dish mixture that separates into three layers as it bakes.
A great alternative to traditional Christmas pudding
If you are anything like me, then you will always stuff yourself to bursting point at the Christmas dinner table and then not have room left for any Christmas pudding.
This impossible Christmas tart get round that problem nicely. It’s not at all stodgy, and served ice cold from the refrigerator, it makes a light an refreshing alternative to the traditional heavy puddings that are served at Christmas.
The custard is soft and creamy, and the pastry layer is filled with just enough fruit mincemeat to give this tart enough of a Christmas taste without being too stodgy.
What’s more, it only takes a few minutes to mix before it goes into the oven. And because it’s best served ice cold, you can make it the day before and just store it in the refrigerator until you are ready to eat it.
If you want to go all out you could serve it covered with custard or brandy sauce, or even top it with a scoop of icecream. To be perfectly honest though, I think it’s fine just served by itself.
And of course, this impossible Christmas tart isn’t just a Christmas pudding. A slice of this tart makes a great tea-time treat instead of the normal Christmas mince pies.
How to make an impossible Christmas tart
***You can print off the complete recipe for this impossible Christmas tart from the recipe card at the end of this post***
You will need a few simple ingredients:
- Flour – this should be plain all-purpose flour not self-raising flour. There’s no baking powder in this recipe.
- Fruit mincemeat – I used the supermarket own brand because this particular one doesn’t have mixed peel in it (I’m not a love of mixed peel). Use your own favourite brand.
- Milk – either full fat or semi-skinned is fine.
- Sugar – this recipe calls for less sugar than a normal cake to compensate for the sweetness of the fruit mincemeat. For this recipe I’ve allowed half a cup of sugar (that’s 100 grams). If you would prefer it a bit sweeter add a little extra sugar, but I wouldn’t go above three-quarters of a cup in total (150 grams).
- Eggs – I used 4 medium-sized eggs
- Butter – if you use salted butter then don’t add any salt to the mixture. If you have unsalted butter then you might like to add half a teaspoon of salt.
- Vanilla essence – for extra flavour – you can leave it out if you don’t have any in your pantry.
If you want to turn this into a boozy version, you could swap out some of the milk as follows:
- 50 ml of milk for 50 ml Baileys Original Cream Liqueur; or
- 1 tablespoon of milk for 1 tablespoon of brandy
What to do
Start off by mixing the flour, sugar, milk, eggs and vanilla essence in a mixing bowl.
The next step is to melt the butter either in the microwave or in a pan on the stove.
Finally stir in the fruit mincemeat. You will find that the mincemeat changes the colour of the batter slightly, but don’t let this worry you. It will still taste delicious.
Grease a 10-inch round baking dish with a little melted butter.
Pour the mixture into the greased baking dish.
If you are worried about the tart overflowing in the oven, just place the baking dish on a baking sheet before placing in the oven.
Bake in a medium oven (175C / 350F) for 1 hour.
Ovens can vary so keep your eye on it. You may find that your tart is cooked after 50 minutes.
Don’t expect the entire tart to puff up. It will only puff around the edges.
The tart will be cooked when it feels firm to the touch and no longer ‘jiggles’ if you shake the dish. If your tart starts to brown too much before the centre has set properly, just cover the edges with a strip of tinfoil.
This is a close up of the finished tart.
The top of the tart will be quite moist and sticky. This is due to the sugar in the fruit mincemeat rising to the top and forming a slight syrupy texture on the top.
Remove it from the oven and allow to cool completely before covering with tinfoil or plastic wrap and storing in the refrigerator.
The final photo shows the texture of the underside of the tart.
Even though there is a layer of custard in this impossible tart, the texture is quite firm. Once the tart has cooled in the refrigerator you will be able to cut it into slices and pick it up in your fingers. It will hold its shape nicely.
When you are ready to serve, dust the tart with icing sugar. Don’t do this too far in advance because the top of the tart is quite moist and the icing sugar will just dissolve.
Unfortunately this tart is not suitable for freezing.
However you can make it up to three days in advance and store it in the refrigerator covered in tinfoil or plastic wrap.

If you live at a high altitude you may find you need to adjust your baking recipes to compensate for this. You can read all about it in this post on baking at high altitudes.
