In a large bowl combine maple syrup, melted vegan butter, and vanilla. Next, add rice flour, buckwheat flour, cacao powder, baking powder, and salt. Create a smooth dough and put it into the fridge for about 30 minutes.
After 30 minutes add the dough to the cookie maker or piping bag with a star nozzle.
Create a round shape and use fingers to smooth the cookie from the sides, so you can have a perfect circle.
Put the cookie wreaths onto the baking paper and bake at 400F (200°C) for 12 minutes.
When the cookies are baked, let them cool down and decorate with melted vegan chocolate and sprinkles. Enjoy!
