Mix almond flour, walnut butter, sugar, and milk together until smooth
Once mixed, let the dough rest for 5 minutes. The dough will be sticky at first but it just needs some time for the almond flour to absorb the liquids.
Divide dough into 6 equal pieces
Flatten each piece of dough into a disk, then wrap the prepared brownie square with the dough
Use a ligtly greased*** mold to press the dough into mooncake shapes and set onto a clean parchment paper. I used a 75g mooncake mold, but you can use any mold size you have at home - just be sure to adjust the filling size!
Bake in a preheated 340F / 170C oven for 11-13 minutes, or until the tops are lightly browned.
For the best texture, store these mooncakes inside an airtight container and chill overnight in the fridge. The mooncakes actually taste better the day after.
Enjoy!
