Preheat oven to 350 degrees Fahrenheit. Line 2 baking sheets with parchment paper.
In a medium bowl, combine cane sugar and egg. Using an electric mixer on medium speed, mix to incorporate. Add melted butter, followed by honey and vanilla. Mix for about a minute until well incorporated.
Add almond flour, baking soda, cream of tartar, and salt. Mix again until dough forms. Chill for 20-30 minutes in refrigerator.
Place coating ingredients in a shallow bowl or plate. Use a fork or whisk to combine sugar and cinnamon.
Use a tablespoon to scoop out dough, then roll into a ball. (Dough is slightly sticky, use cooking spray on hands if needed). Place dough ball on plate with cinnamon-sugar, roll to coat, then place on prepared baking sheet.
Bake for 10-12 minutes. Bottom and tops should start to turn golden. Use a spatula to transfer cookies to a wire rack to cool.
Notes
The dough is sticky, so dipping your hands in water or spraying with cooking spray will help when rolling the balls.
Make it vegan: Sub 1 tablespoon of tapioca starch mixed with 3 tablespoons of cold water as an egg replacer. Replace the honey with maple syrup or agave syrup.
To store: Store cookies in an airtight container at room temperature for 3-5 days.
