Preheat the oven to 350°F. Line a cupcake tin with 12 parchment paper cupcake wrappers.
In a large mixing bowl, combine the tapioca flour, cassava flour, coconut flour, cane sugar, salt, and baking powder. Whisk until combined.
Add the avocado oil, eggs, vanilla, and yogurt. Stir until a smooth batter forms.
Working quickly, use a 1/3 cup measure to scoop the batter into the cupcake liners. Fill the liners about 3/4 full, you should be able to fill 12 cupcake liners. Let the cupcakes rest for 5-10 minutes before putting them in the oven.
Bake for 22-25 minutes. The cupcakes should bounce back when gently pressed on top.
Remove from the oven and allow the cupcakes to cool for 5 minutes before removing them from the cupcake tin onto a cooling rack. Let them cool completely before frosting them.
