I have to tell you the twists and turns it took to arrive at this recipe... haha. So, as you may know, I have a shop where I offer cakes made to order! Since I'm always short on time and need to optimize my work, I have a rule: each baking preparation (a dough, a cream...) must be used for at least 2 different things! And I had a problem when someone ordered a lemon tart. The biscuit underneath was only used for that tart. So I started making lemon and thyme biscuits at my shop using this biscuit dough. They were very popular and became one of the permanent pastries in our display. But then I had to start making these biscuits all the time, even when I didn't have a lemon tart order haha... So the problem arose again, as it only served one single preparation! So I began dividing the dough in half to make, on one hand, lemon-thyme biscuits and, on the other hand, these chocolate biscuits that I vary with caramel, coconut, hazelnuts...

As for the electric whisk technique, it came about because coconut oil is incredibly hard in winter in my kitchen, too hard to be worked by hand. So it's much more practical this way!

It's always like this with my recipes, they start from something else and then, through modifications and new ideas, they turn into something else!
