“I’ve been making it for my son for 20 years”: the simple orange cake French families swear by

Father and son cutting a cake together in a kitchen with baking ingredients on the counter.

In a French home kitchen, a television chef has been quietly keeping the same sweet routine going for 20 years, relying on little more than oranges, butter and affection.

This is neither a showstopping dessert nor a viral “hack”. It’s a soft orange cake-an easy, family bake-that a familiar presenter says he has made for his son for two decades. The recipe is almost laughably straightforward, based on everyday cupboard staples plus a handful of juicy oranges, and yet it has outlasted every passing food craze while still underpinning their weekend snacking.

The aim: a soft, citrus-scented cake anyone can bake

The cake sits firmly in the “soft and moist” category: gently rich, but never heavy. Its character comes mainly from fresh oranges, using both zest and juice. There’s no elaborate icing, no syrup that needs constant attention on the hob, and no lengthy resting period.

"This is the kind of recipe you can throw together while the kettle boils, and still feel like you’ve made something special."

Rather than demanding ultra-precise baking, it follows a memorable framework: equal weights of butter, sugar and flour, plus three eggs. That simple structure is easy to retain, which helps explain how it has stayed in one family’s regular rotation for so long.

Laurent Mariotte’s cake that grew up with his son

French food commentator and TV host Laurent Mariotte spends a large part of his working life in professional kitchens. Even so, the recipe he speaks about with the most warmth is a home one-baked for his wife and his son, Léonard: a delicate orange sponge he has been making since his child was little.

"I’ve been making it for my son for 20 years," he says, as if he’s talking about a family photo album rather than a cake.

In France, the mid-afternoon snack between school and dinner is close to a childhood institution. Instead of opening a packet of shop-bought biscuits, Mariotte turns to this one-bowl orange cake. It’s quick, aromatic, and uses ingredients many households already keep to hand.

Ingredients: the 125–125–125 rule

The foundation is so simple you can learn it in moments. Below is Mariotte’s version, measured for a standard round tin:

  • 125 g plain flour
  • 125 g caster sugar
  • 125 g unsalted butter, softened
  • 3 eggs
  • 3 to 4 oranges
  • 1 packet baking powder (about 10–11 g)

He suggests Washington oranges for their size and juiciness, although most sweet eating oranges will do the job. Since the peel is used for zest, he leans towards organic fruit to reduce wax and pesticide residues on the skin.

Why equal weights work

Using matching weights of sugar, butter and flour is a classic European method. It helps the sponge rise without becoming heavy, while the butter and sugar help retain moisture-one reason the cake keeps its hallmark softness even the next day.

Ingredient Role in the cake
Butter Adds richness, tenderness and flavour
Sugar Sweetens and helps keep the crumb moist
Flour Provides structure so the cake holds together
Eggs Bind the batter and help with rising
Orange juice Brings acidity and aroma, softens the crumb
Orange zest Concentrated citrus flavour and perfume

Step-by-step: from bowl to plate in under an hour

This approach is built for busy parents and impatient children. You won’t need a stand mixer or any specialist kit-just a bowl, a whisk and a cake tin.

1. Heat the oven first

Put the oven on at 180°C (fan). If you’re using a conventional (non-fan) oven, aim for about 160–170°C; if you’re working in Fahrenheit, use 350°F. Preheating matters because the baking powder starts working properly as soon as the batter hits the heat.

2. Cream butter and sugar

In a large bowl, beat the softened butter and sugar together until pale and creamy. This stage helps hold tiny pockets of air that support the rise.

3. Add eggs and citrus

Mix in the eggs one by one, beating well after each addition to prevent the mixture from splitting. Next, add roughly 100 ml (10 cl) of freshly squeezed orange juice, plus the finely grated zest of two oranges.

"The zest is where most of the floral, almost perfumed orange notes live – you miss that if you only use juice."

4. Fold in dry ingredients

Sift the flour and baking powder together, then add to the bowl. Stir until you can’t see any floury streaks, but stop before the batter becomes stretchy-too much mixing can make the cake firm.

5. Prepare the tin and bake

Grease and flour a 20–24 cm round tin, or line it with baking paper. Spoon in the batter, smooth the top, then bake for 25 to 30 minutes. It’s ready when the surface is golden and a skewer inserted into the centre comes out clean, or with just a few moist crumbs.

The clever extra step: soaking with more orange juice

Once the cake is baked, Mariotte doesn’t treat the sponge as the finish line. Around five minutes after it comes out of the oven, he advises soaking it with a further 100 ml of orange juice.

At that moment the cake is still warm and open-textured, so it takes in the juice without collapsing. You end up with a cake that’s intensely fragrant and lightly tangy-somewhere between a classic sponge and a syrup cake, only without a heavy sugar syrup.

"That final pour of juice turns a simple family cake into something you might quietly serve at a dinner party."

Most often it’s eaten plain, occasionally finished with a delicate dusting of icing sugar. It works well alongside coffee, black tea, or a citrus-led herbal infusion, which helps balance the buttery crumb.

How to adapt it to your own kitchen

If you’re cooking outside France, Washington oranges may be hard to come by, but other types fit in easily. Blood oranges bring a deeper colour and a more layered flavour with a faint berry note. Navel oranges are dependable and easy to find. Steer clear of very sharp, juicing-only varieties unless you slightly increase the sugar.

If you’re avoiding dairy, you can replace the butter with a neutral vegetable oil. The crumb will shift a little-closer to a soft pound cake-but it will remain moist. Gluten-free flour blends can also work; adding an extra spoonful of juice helps keep the batter loose enough.

Keeping the ritual, changing the flavour

Because the structure is so reliable, it also works as a base for other variations:

  • Swap the oranges for lemons for a brighter, sharper, tea-time style loaf.
  • Add a handful of dark chocolate chips to the orange version for a Terry’s-like twist.
  • Mix in a spoonful of ground almonds (and reduce the flour slightly) for a nuttier crumb.
  • Lay thin orange slices in the bottom of the tin to create an upside-down effect.

What doesn’t change is the emotional core: a repeatable, low-effort bake that marks time through a child’s life. It’s easy to imagine the stages-from a toddler licking the bowl, to a teenager cutting a thick slice before homework, to an adult later baking the same cake for someone else.

A few handy notes for new bakers

If baking makes you nervous, this recipe is on your side. The baking powder provides dependable lift even if you’re not measuring to the gram. Citrus is forgiving too: the juice added at the end helps soften the crumb, which can disguise slight overbaking.

A few small details do make a noticeable difference. Butter at room temperature blends far more smoothly with sugar than a cold block straight from the fridge. Organic or unwaxed oranges lower the risk of zest tasting bitter or waxy. And allowing the cake to stand for 10–15 minutes before slicing helps prevent it from breaking apart.

"This is less about patisserie perfection and more about creating a repeatable comfort that fits around modern family life."

For families hoping to improve snack habits, this orange cake can be a sensible middle ground between industrial biscuits and fully elaborate “showstopper” bakes. It only asks for one bowl, a whisk, and about half an hour of slightly sticky, slightly chaotic calm-the sort of moment that often stays in the memory longer than the recipe itself.
