Santiago Cake

A few months ago, I had a moment when I wanted to make a quick tart for some guests and realized, just when I was about to start, that I didn’t have any almonds. I was craving something sweet and crunchy with a hint of lemon flavor. Instead of stressing out, I directly replaced them with walnuts since that’s what I had, and it turned out to be the best decision; it came out even better than I expected. The funny thing is that everyone asked for the recipe, and since then, I make it quite often, sometimes with almonds when I feel like sticking to the "original," but I admit, with walnuts it has that homey taste. By the way, the first time I forgot the tart in the oven and burnt the edges a bit, so don’t panic if it smells a bit stronger at some point. I can’t remember who, but someone always eats it with whipped cream, as if the filling isn't rich enough. Anyway, everyone has their quirks.

To keep it brief:
Total time – about 1 hour, including the laziness between steps. Actual working time, 20-25 minutes.
Servings – if you cut it somewhat evenly, you’ll get 10-12 slices, but honestly, it disappears in 8 at our place.
Level – very easy, even if you’re not great with dough or lack patience for complicated sweets.

Why do I keep coming back to this recipe? Because it’s one of the few desserts that turns out just as good with walnuts or almonds, and even if you’re not in the mood for complicated cooking, it comes together quickly. Plus, if you have guests, it rarely fails; it works for coffee, as a dessert after a meal, or for taking away. It’s one of those things you can leave to cool in the kitchen, and you find it getting thinner by the evening, as someone “accidentally” nibbles at it. When I don’t have apricot jam, I use whatever I have in a jar, but I admit, apricots match best; that slight tartness ties everything together in the end.

Ingredients:
- 1 package of puff pastry (400-450g, that’s what I found in stores, and I prefer the butter version if I can find it, it tastes better)
- 3 medium-sized eggs – I whisk them by hand, it’s not rocket science
- 175g granulated sugar (sometimes I use 150g if I want it less sweet, it doesn’t hurt)
- grated zest of one lemon, preferably untreated or well washed; I love that fresh aroma, not chemicals
- 200g ground walnuts (or almonds, if you have them, but as I said, I use whatever I have at home; it should be coarsely ground, so you still feel some crumbs)
- 1/2 teaspoon of cinnamon, but I never measure to the milligram – if you’re a fan, you can add more, but it shouldn’t overpower the other flavors
- 3-4 generous tablespoons of apricot jam (maybe even more, depending on how thick it is)
- powdered sugar for the finish, don’t be stingy
- optional: a little water if the jam is very thick or dry

The puff pastry is the base that holds the tart, giving it that nice crunch. The eggs and sugar create a fluffy filling; I don’t think I need to explain much here. The lemon zest changes everything; without it, the filling feels too heavy, and the cinnamon adds a touch of mystery (sounds cliché, but it’s true; without cinnamon, it lacks character). The walnuts or almonds provide texture and a distinct flavor, so don’t skimp. The apricot jam caps it all off, bringing together the story and giving that sweet-tart contrast, and the powdered sugar… I don’t even need to say, it’s for decoration, but it just doesn’t feel the same without it.

1. First, I take the puff pastry out of the freezer and let it thaw, but not too long, so it doesn’t get soggy and hard to roll out. It should be slightly cold; then it fits well in the pan. I set the oven to 180°C, medium heat, not too hot, not too soft.

2. I line the tart pan (or whatever pan you have; shape doesn’t matter, but it’s important that the edges are a bit higher, about 3-4 cm). If I have it, I grease it with a little butter, which never hurts. I place the puff pastry in the pan, gently press it on the edges, and trim the excess. Then I put the pan with the dough in the fridge for about 30 minutes. I don’t know why, but it turns out crispier this way, probably because the butter in the dough doesn’t melt before it goes into the oven.

3. In the meantime, I whisk the eggs with the sugar until they lighten in color, about 3-5 minutes with a whisk or mixer, depending on how much energy I have. It doesn’t need to be foamy, just homogeneous.

4. I grate the lemon zest and add it to the mixture, stirring it in. I add the cinnamon and ground walnuts, incorporating them with a wooden spoon or spatula; it doesn’t matter how, the idea is not to mix too hard, just enough to combine everything. The mixture will be quite dense; don’t be alarmed, that’s how it should be.

5. I take the pan out of the fridge, pour in the filling, and level it gently. I put everything in the oven at 180°C, on the middle rack, without a fan. It usually takes 30-40 minutes, depending on the oven, but I check from time to time – it should be lightly browned on top and not jiggle when I move the pan.

6. I take it out and let it cool. Very important, don’t take it out of the pan while it’s warm, or it will break. I’ve had that happen a few times; the base cracked, and I had to improvise when serving, but no one died.

7. When it’s completely cool, I carefully remove the tart from the pan. If you have a removable ring, it’s even easier. If not, I run a knife along the edges and “help” it out gently, being careful not to crumble it.

8. I warm the jam a bit with 1-2 tablespoons of water if it’s too thick or hard. I put it on low heat until it becomes more liquid; if there are large pieces, I strain it to make it smooth. I spread the warm jam over the tart, making a thin but even layer.

9. I generously dust with powdered sugar, using a fine sieve; I like it to be thick because otherwise, it doesn’t look nice when cut.

10. I let it sit for 10 minutes to settle, then cut it into somewhat equal slices. It goes wonderfully with a spoonful of natural whipped cream on the side or with vanilla ice cream, but at my place, it’s always requested with whipped cream.

Tips, variations, and serving ideas

Useful tips:
- Don’t take the tart out of the pan while it’s warm; it will almost certainly break if you’re too rushed.
- For extra crispiness, you can poke the puff pastry with a fork before putting in the filling. Some bake it empty for 5 minutes beforehand, but I don’t do that because it tends to separate from the edges.
- Don’t put too much jam – I did that once, and the tart got “drowned,” plus the powdered sugar wouldn’t stick.
- If you want the tart less sweet, reduce the sugar or choose a more tart jam; don’t be afraid to adjust to your taste.

Substitutions and adaptations:
- Almonds or walnuts – use whatever you have at home; I’ve tried a mix (half and half), and it was fine.
- For a gluten-free version, look for gluten-free puff pastry (it’s a bit pricey, but it works) or make a quick crust from almond flour, butter, and egg – it turns out more tender, not as crunchy as puff pastry.
- If you don’t have lemon, use orange, but reduce the sugar a bit; oranges are sweeter.
- For a diet version, you can reduce the sugar or replace it with a sweetener like erythritol (I’m not a big fan, but some say it works).

Recipe variations:
- I’ve also made it with raspberry or blueberry jam; it didn’t turn out bad, but apricots are still my favorite.
- If you want to make it fresher, add a few drops of vanilla extract to the mixture.
- For something more substantial, sprinkle some flaked almonds or walnuts on top before baking – it gives a nice appearance and a bit of texture.

Serving ideas:
- It goes great with strong coffee in the morning.
- As a Sunday dessert after a heavier lunch – it’s not too rich, but it fills you up.
- For taking to work or school, it holds up at room temperature for a day, it doesn’t spoil.
- I’ve also tried it with a scoop of vanilla ice cream – no offense, but that combination is just perfect.

Frequently asked questions

1. Can I use tart dough instead of puff pastry?
Yes, it works very well. Classic tart dough is more tender, not as airy and crispy as puff pastry, but it holds the filling perfectly. If you want to make it at home, quickly mix flour, butter, and a bit of cold water, then let it chill for about half an hour. Bake it a little before adding the filling so it doesn’t get too soggy.

2. My filling turned out a bit runny – what am I doing wrong?
It’s probably because the eggs were very large, or you didn’t measure the walnuts/almonds accurately. If you see it’s too thin, add 2-3 more tablespoons of ground walnuts and mix gently. Anyway, it sets quite well after baking, so don’t worry too much.

3. Can I freeze the tart?
Yes, but only if it’s not spread with jam. Freeze it after it has completely cooled, possibly cut into slices. Let it thaw at room temperature, then spread with jam and dust with sugar when serving. I don’t recommend freezing with jam, as it loses its texture and becomes soft.

4. Can I replace apricot jam with something else?
Absolutely. Peach, plum jam, or even berry preserves work, but they should be a bit tart, not too sweet. I once used a quick berry sauce – it worked well.

5. Can I add dried fruits or raisins to the filling?
Sure, but don’t overdo it. A handful of raisins or cranberries works, but don’t overcrowd the mixture, or it won’t rise nicely. You might want to hydrate them a bit beforehand so they don’t draw moisture from the eggs.

6. Does it turn out just as well with brown sugar?
Brown sugar is good too; it gives a slightly different, more caramelized taste. I’ve used it a few times, but it’s less sweet, so you can add a tablespoon if you want the same intensity.

Nutritional values (approximate, don’t ask me for exact numbers)

For a decent slice (about 1/10 of the tart), you have around 250-300 kcal, with variations: if you add whipped cream or ice cream, it quickly rises to 350-400 kcal. The carbohydrates mainly come from sugar and puff pastry (about 25-30g/slice), fats from nuts/walnuts, eggs, and dough (approximately 15-18g/slice), proteins 5-7g. It’s a fairly filling dessert, but it’s not a caloric bomb if you don’t overdo the portion. It also has good fats from nuts, not just sugar and flour – that’s why I like it; it’s not the kind of sweet that leaves you with guilt after one slice. It’s clearly not low carb, but it’s not at the level of bakery sweets either.

How to store and reheat

If there are leftovers (which rarely last until the next day at my place), it keeps well in the fridge, covered or in a box, for about 3-4 days. It even gets better the next day when the flavors meld, and the puff pastry isn’t as crispy, but it doesn’t become soggy. You can leave it at room temperature for a whole day; it won’t spoil.

Reheating… it’s not necessary, but if you want to eat it warm, pop a slice in the microwave for 10-15 seconds or a few minutes in the oven at 120-140°C. Be careful, if it’s already spread with jam, don’t keep it too long on heat; otherwise, the powdered sugar melts and becomes sticky. I prefer it at room temperature, as the filling doesn’t harden and stays more aromatic. If you know you want it for several days, it’s better to add the jam and powdered sugar to each slice at serving time; that way, it holds up better and doesn’t get soggy on top.

Overall, it’s the kind of dessert you can quietly grab on the go if you get a sweet craving in the evening. And although it seems simple at first glance, everyone has asked for the recipe, a sign that sometimes the simplest combinations yield the most flavor.

We line the tart pan with dough and let it rest in the refrigerator for 30 minutes. Whisk the eggs well with sugar, add lemon zest, cinnamon, ground almonds, and mix with a spoon; pour the mixture into the pan and bake in the oven at medium heat until golden brown; remove the tart and once it has cooled, take it out of the pan, spread it with jam, then a generous layer of powdered sugar. Serve the tart sliced with whipped cream (optional). If the jam is too thick, mix it with a little water, let it simmer for a few minutes, then strain.
