Looking for a cafe with “thousand-layer French butter” croissants in Hanoi

Croissant is not just “croissant-shaped bread”! Don’t let that stop you from enjoying a thousand-layer French butter croissant with natural yeast at XLIII Coffee Hanoi !

Croissant is more than just a croissant

There is no shortage of places selling croissants in Hanoi. But how many times have you bitten into one and been disappointed?

• It was soft and dense like a normal sweet bread.
• It is sweet and has a strong margarine taste.
• And worst of all, after eating, you feel full, have indigestion and are “sick” all the way down to your throat.

That’s not a Croissant. That’s just “croissant bread.”

A true French food lover will look for a different experience: the crunch of the crust, the airy honeycomb texture inside, and most importantly, a complex flavor that is not only rich but also deep.

XLIII Coffee creates that experience with a “secret weapon” called Sourdough Yeast.

Sourdough Croissant is classic technique & modern thinking

Most Croissant on the market is made with Commercial Yeast to help the bread rise quickly (takes only 1-2 hours) and optimize profits.

At XLIII Coffee’s bakery kitchen ( Hanoi, Da Nang, Saigon ), we chose a path 10 times more difficult: Slow fermentation with Sourdough Starter .

Why choose such an option?

• Multi-layered flavor : Commercial yeast has only one taste: bland. Sourdough yeast is a living microorganism. It creates tangy, fruity, and natural umami flavors. When combined with French butter, it creates the perfect balance: rich but not greasy.
• Honeycomb Structure : Natural yeast makes the gluten framework stronger yet more elastic. When you cut across the XLIII, you will see large, regular air holes and a very thin film. This will be the clearest evidence of the manual thousand-layer dough rolling technique.

“Guilt-Free”: Eating sweets without harming your body

This is for those of you who care about your health but still love sweets.

Do you know why eating bread often causes bloating? Because gluten and starch are not processed properly.

The slow fermentation process (lasting 24-48 hours) of Sourdough at XLIII Coffee acts as an “external digestive system”. The natural bacteria (Lactobacillus) have “pre-digested” a large part of the gluten and starch in the flour.

• Result : This Croissant is extremely easy to digest.
• Lower glycemic index (GI) : It doesn’t spike your blood sugar like regular white bread.

You can enjoy a fragrant French butter croissant for breakfast while still feeling light and refreshed.

The ingredients are absolute honesty.

A Croissant Sourdough cannot hide poor quality ingredients.

• Premium French Butter : XLIII Coffee uses AOP butter lines (such as Elle & Vire or Isigny) with a fat content of over 82%. Absolutely say no to Margarine or Shortening.
• Unbleached Flour : To nurture healthy Sourdough yeast, the flour must be of the highest quality, rich in protein and minerals.

When you eat it, you taste the real flavor of fermented wheat and the real flavor of evaporated milk. No artificial vanilla flavoring can imitate it.

Is a Sourdough Croissant at XLIII Coffee more expensive than the ones on the market? Of course . Because you are paying for 48 hours of yeast and baker’s labor, for imported ingredients, and for your own health. Come and enjoy a combo of a Filter Coffee (Pour-over ) and a Sourdough Croissant, to see what Patisserie meets Specialty Coffee . The bright acidity of the coffee will support the richness and light sourness of the cake, creating the pinnacle of European breakfast.

Frequently Asked Questions

1. Is sourdough bread too sour?

Not at all. With buttery breads like Croissant, the acidity of the yeast is controlled very delicately. It only appears lightly in the aftertaste, helping to cut through the richness of the butter, making the bread taste “brighter” and “deeper” rather than as sour as whole wheat Sourdough bread (Loaf).

2. How do I know if the cake is fresh?

Take a look at the open kitchen of XLIII Coffee in Hoan Kiem, or feel the crispness of the crust. Croissants left overnight will lose their crispness due to moisture absorption. At XLIII Coffee, they are baked fresh every morning. If you arrive on time, you might even find them warm.

3. Can I buy it to take away and reheat it?

Yes. But please don’t microwave (it will turn the cake rubbery). Use an oven or air fryer at 160-170 degrees Celsius for 2-3 minutes. The crust will be crispy again like it just came out of the oven.

4. Is this cake suitable for dieters?

While it still contains calories from butter and flour, the Sourdough Croissant is the “healthiest” choice in the pastry world thanks to its easy digestion and lower glycemic index. It’s perfect for a quality “Cheat Day” or a breakfast that needs clean energy.
