Recipes from Pierre Hermé guarantee a success. Don’t they? :) These cookies are from his “Chocolate Desserts“. I’ll just quote Dori Greenspan in her precise description of them: “Soft and crumbly, buttery and chocolaty, these are the cookies of old-fashioned Austrian bakeries… easy to make… easy to pair with coffee, tea, or ice cream desserts”.
You won’t even need a mixer for making the dough – it’s mixed by hand.
