Melt-in-Your-Mouth Margaret Cookies
Discover the secret to perfectly crumbly, melt-in-your-mouth Margaret cookies. Made with a sieved hard-boiled egg yolk and cornstarch, these delicate treats are beautifully buttery and topped with toasted black sesame.
Margaret cookies, originally known as Italian hard-boiled egg yolk cookies, are beloved for their incredibly tender, crumbly texture. The secret lies in passing a cooked egg yolk through a fine sieve, which prevents gluten development and ensures the dough remains delicate. Distinctive for their thumbprint shape and crumbly edges, these cookies are a timeless favorite that require minimal ingredients and effort.
Ingredients
- 50 g unsalted butter (melted)
- 1 hard-boiled egg yolk
- 30 g sugar
- 1 pinch salt
- 50 g cornstarch
- 50 g low-gluten flour
- 1 egg yolk (for egg wash)
- to taste black sesame seeds
Instructions
- 1Pour the butter

Begin by pouring your prepared melted butter into a clean glass mixing bowl. Ensure you scrape all the butter from the pot using a spatula to get every bit.
Tip: Make sure your butter is fully melted but not boiling hot before pouring it into the bowl to avoid cooking the egg yolk prematurely later. - 2Sieve the egg yolk

Take a hard-boiled egg yolk and press it through a fine-mesh strainer directly into the bowl of melted butter. Using a spatula to push the yolk through helps achieve a perfectly smooth, fine texture.
Tip: Sieving the yolk is the secret to the signature melt-in-the-mouth texture of Margaret cookies. - 3Whisk in seasonings

Add a small amount of sugar and a pinch of salt to the bowl containing the butter and sieved egg yolk. Whisk the mixture thoroughly until the ingredients are completely combined and the texture is smooth.
Tip: Ensure the sugar is well-incorporated into the butter-yolk mixture so you dont get grainy cookies. - 4Form the dough

Add 50 grams of cornstarch and 50 grams of low-gluten flour to the mixture. Knead the ingredients by hand until they come together into a soft, non-sticky dough.
Tip: Be careful not to over-knead the dough, as this can make the cookies tough rather than crispy. - 5Shape the cookies

Take small, equal portions of the dough and roll them into uniform, smooth balls. Place the balls onto a baking sheet that has been lined with parchment paper.
Tip: Keep the balls consistent in size to ensure they bake evenly in the oven. - 6Create the signature shape

Using your thumb, press down gently into the center of each dough ball on the baking sheet. This creates the classic flattened shape and indentation characteristic of Margaret cookies.
Tip: Press firmly enough to flatten slightly, but dont press all the way through to the tray. - 7Apply egg wash

Using a pastry brush, gently apply a thin, even layer of egg yolk wash over the surface of each pressed dough ball. This will give the cookies a beautiful, glossy golden finish once baked.
Tip: Be gentle when brushing to avoid flattening the shape of the dough. - 8Garnish with black sesame seeds

While the egg wash is still wet, sprinkle a small pinch of black sesame seeds onto the center of each cookie. The seeds provide a pleasant texture and a nutty flavor that contrasts well with the buttery dough.
Tip: Use your fingers or a small spoon to distribute the seeds evenly, focusing on the center indentation. - 9Bake the cookies

Carefully place the baking sheet into a preheated oven at 150 degrees. Bake for 20 minutes until the cookies are firm and golden brown, ensuring they are crispy throughout.
Tip: Keep an eye on the cookies during the last few minutes of baking to ensure they reach the perfect golden color without burning.
