Back in September and for the whole school year, I ran a series I loved putting together: "Tour of Italy," one region per month. When in March we landed on Campania, I made a Caprese al Limone, not really knowing how it would go over — and the response surprised me. So many of you asked for the recipe afterward that I knew I couldn't just let it disappear after one month. So here it is, finally written down.
The cake that started with a mistake.
I just discovered that there is a particular story behind this cake: torta caprese was born on the island of Capri, almost a hundred years ago, completely by accident. The story goes that a pastry chef was making a chocolate almond cake and simply forgot to add the flour. What came out of the oven wasn't a failure — it was something better: dense, moist, almost fudgy in the middle, with a thin crust on top. It became one of the most famous desserts in Southern Italy, and it's stayed essentially unchanged for decades: almonds, butter, eggs, sugar, no flour, ever.
The lemon version is newer — it's a riff on that original recipe, swapping the dark chocolate for white chocolate and bringing in lemon, which is how Campania's coastline really tastes to me. I based my version on a traditional recipe from a famous Italian Blog “Giallo Zafferano”, and then made a few adjustments of my own along the way.
Why white chocolate and lemon works.
This isn't a pairing people think about much, but it's quietly one of the best combinations I know. White chocolate brings richness and a little bit of weight — it can be almost too much on its own. Lemon cuts straight through that, brightens everything up, and keeps the cake from feeling heavy. The almond base ties it all together and keeps the texture moist and a little dense, the way a good caprese should be.
A note before you bake.
Because this cake is made with almond flour instead of wheat flour, it's naturally gluten-free in its ingredients. I want to be upfront with you, though: my kitchen is not a dedicated gluten-free or nut-free space, so if you or someone you're baking for has a serious allergy or celiac disease, please keep that in mind — there's always a chance of cross-contact with other ingredients we use day to day. If that's a concern, this is one to make carefully at home with your own gluten-free certified ingredients, rather than relying on anyone else's kitchen, including mine.
Caprese al Limone
Makes one 9-inch cake
Ingredients:
- Almond flour — 250g / 8.8 oz (gluten-free certified, if needed)
- White melted chocolate — 200g / 7 oz
- Granulated sugar — 200g / 7 oz
- Unsalted butter, softened — 120g / 4.2 oz
- Potato starch — 50g / 1.8 oz
- 5 large eggs, separated
- Baking powder — 5g / about 1 tsp
- Zest of 3 unwaxed lemons
- ½ vanilla bean (or 1 tsp vanilla extract)
- Powdered sugar, for dusting
Method:
1. Zest the lemons, squeeze the lemons, and set both aside — you'll want both ready before you start mixing.
2. In a bowl, beat the softened butter with half the sugar until light and fluffy.
3. Add the egg yolks one at a time, beating well after each addition. Then add the lemon zest, vanilla and mix well.
4. Add the melted chocolate, mix and the lemon juice and mix.
5. Gather in a bowl almond flour, potato starch and baking powder.
5. In a separate bowl, whip the egg whites with the remaining sugar and stop just before you get stiff, glossy peaks.
6. Fold into the batter the egg whites alternated with the dry ingredients in two or three additions, working from the bottom up with a spatula so you don't knock the air out. The batter will be fairly thick — that's normal.
7. Pour into a buttered and floured (or potato-starch-dusted) 9-inch round pan and level the top.
8. Bake at 340°F (170°C) for about 45 minutes, until a toothpick comes out with just a few moist crumbs — this cake stays a little fudgy inside, so don't expect it to come out completely clean.
9. Let it cool completely, then turn it out onto a plate and dust with powdered sugar.
Notes:
- Store at room temperature under a cake dome for 3–4 days, or in the fridge if your kitchen runs warm.
- It also freezes well — slice it first, then wrap individual pieces so you can pull out just what you need.
- Recipe adapted from a traditional Caprese al Limone method, similar to the version associated to the famous Italian Blog Giallo Zafferano.
If you make it, I'd love to hear how it turns out. And if you'd rather skip the baking altogether, you know where to find a slice — it's back on the menu this month.
Talk soon,
