1. Start this Grenoblois coffee cake recipe by blending the walnut kernels. Combine the sugar and egg yolks in a bowl, then whisk them with an electric mixer until the mixture becomes pale. Add the black coffee, blended walnuts, and cornstarch, then mix.
2. Preheat the oven to 180 °C (350 °F). Whisk the egg whites with a pinch of salt in another bowl. Gently fold them into the previous mixture. Grease a round cake pan and pour the batter into it. Bake for about 40 minutes, keeping an eye on the browning.
3. Remove the cake from the oven, let it cool slightly, then unmold it onto a cooling rack to cool completely.
