Chocolate crackle cookies - the science
Why do these cookies crinkle when baking? That's the question we need to ask in order to understand how to make them well. The first thing I'll explain is the double action of the baking soda and baking powder in the cookie. In a way, it's much similar to making pancakes or any pound cake. The baking soda, which is an alkaline powder, reacts with any acidic agent (the butter) and creates carbon dioxide, which resolves into gas bubbles that make the dough expand — breaking the icing (confectioners' sugar) and creating the crinkles.Can we control the crinkles?
Nobody can predict how many crinkles there'll be, or how wide or deep they'll go, but we can do our best to create an environment ideal for our style of cookie.The fissures on top of the cookie are created because the coated sugar absorbs all the humidity from the baking, drying out the top surface. The sugar starts to crystallize and draws even more moisture from the cookie.
The secret is coating the cookie in a heavy layer of powdered sugar to create a thick crust that results in multiple crackles.
I've noticed in many recipes that the cookies are rolled first in granulated sugar and then in confectioners' sugar to maximize the cracks.
The logic behind this is that granulated sugar can absorb more humidity and crystallizes better in the oven — it doesn't turn into a syrup texture as easily as confectioners' sugar does.
I tried both methods and didn't find any improvement with the granulated sugar coating. Just roll the dough in a generous amount of powdered sugar and the cookies will be just fine.
Texture and baking
The dough needs to rest in the fridge for a minimum of 1 hour. Some say overnight — too long, if you ask me. The scientific explanation is simple: letting the dough rest wakes up the enzymes that feed on the sugar and break large sugar molecules into smaller ones. Smaller sugar molecules need a shorter baking time. The baking is very fast — 8 to 10 minutes, depending on the size of the chocolate crackle cookies and the resting time. One thing is certain: these cookies will disappear faster than you think, so go ahead and hide some for the next day's coffee.Method
- 1
Making the batter· 15 minutes
Set a bain-marie and melt the chocolate and butter into a smooth ganache, set aside to cool. In a bowl, mix the dry ingredients; the flour, cocoa powder, baking soda, baking powder and salt. In a separate bowl whisk the sugar, eggs and espresso powder. Pour the chocolate ganache in a steady stream into the egg mix bowl and whisk constantly until combined. Fold in the flour mixture and mix until a dough is formed. cover with a plastic wrap and put in a fridge for 1 hour.

forming the cookies· 10 minutes
Preheat the oven to 165°c/ 330°F. Set a confectioner’s sugar bowl and line up 2 baking pans with parchment paper. Take the cooled cookie dough out of the fridge and form into small ball shapes. Drop the chocolate balls into the Icing sugar bowl, cover in a thick layer of powder sugar and place on the baking pan.

Baking time· 8-10 minutes
Place one baking pan in the oven and bake one sheet at a time for 8-10 minutes, until the cookies are puffed and cracked. Cool for 10 minutes before serving.
