Fold in the flour. Bring the dough together, wrap in plastic wrap, then roll into a log.
Slice the log into your desired thickness and arrange the slices on a baking sheet. Bake in an oven preheated to 150°C for 15 minutes, then at 160°C for 2 minutes.
Story Behind this Recipe
I wanted a delicious way to use up egg yolks!
The dough is soft, so the cookies naturally take on the shape that's shown in the picture! They'd be good with some matcha green tea!!!! If you want crispy cookies, just fold the dry ingredients without kneading the dough!
