1. Use an electronic scale to accurately measure out the required materials, and let the butter soften at room temperature
2. Stir the egg yolk slightly with chopsticks
3. The butter is slightly fluffy, and the granulated sugar is added in three times. Note that after adding the granulated sugar, mix it with the butter slightly before beating, otherwise the solid granulated sugar will splash everywhere
4. Add egg yolk and milk, mix well, there is no milk in the dormitory, I will use the same amount of water
5. Add the coconut flour and flour, mix well
6. Roll the dough into a small ball, coat with coconut flour, preheat the oven at 180 degrees for 10 minutes, and bake the middle layer for 15-20 minutes until the surface is golden
7. Do you smell the strong coconut fragrance? Take out the baking tray and put it on the window sill to cool
8. With some fruits and tea, now you can take a break and enjoy a relaxing time
Tips:1. Don't throw away the leftover egg whites, put them in a container and keep them fresh in the refrigerator. They can be used to make cakes and meringues;
2. If the butter is beaten for a short time, the dough will be more shaped and not easy to collapse during baking. If the butter is fully beaten, it will be more crispy, but due to the ductility of the butter, the balls will flatten;
3. The shortbread biscuits can be sealed and dried at room temperature for a week. If it feels damp, take it back to the oven and bake it for a few minutes at 170 degrees and let it cool.
