The pastry chef behind Meghan Markle and Prince Harry's elaborate wedding cake has shared her recipe for chocolate chip cookies.

While her London bakery Violet is closed, Claire Ptak decided to "join the party" on Instagram where she saw people were baking her cookies at home.

A day after sharing photos of her own batch of egg yolk chocolate chip cookies, Ptak shared a photo of the recipe with her followers who might not have "The Violet Bakery Cookbook" themselves.

And though the recipe for Markle and Harry's wedding cake — which was made by Ptak along with a team of bakers, and featured 200 Amalfi lemons and 10 bottles of Sandringham Elderflower Cordial — wasn't super do-it-at-home friendly, Ptak's chocolate chip cookies seem simple to make.

What makes this recipe a bit different from other chocolate chip cookies is that it uses only egg yolks instead of whole eggs

Ptak wrote in her book that using the yolks is a technique she learned while studying in France and it "dramatically changes the texture of a dish."

She shared both the ingredient list — which includes two types of sugar, unsalted butter, vanilla, and, of course, egg yolks — and the baking instructions page. In the photo, you can see that the recipe calls for a baking time of 18 minutes, but in her Instagram caption, Ptak corrected the written recipe and instructed her followers to bake the cookies for "12 minutes only."

The pastry chef also recently shared a recipe for hot cross buns, and has been posting other treats she has been making at home, on her Instagram account.

Representatives for Claire Ptak did not immediately respond to Insider's request for comment.
