Preheat oven to 350°F. Grease bundt came molds with neutral oil.
Pour almond milk into a measuring cup and add in the apple cider vinegar and mix. Let stand for 2 minutes to create vegan buttermilk
Add in the vanilla extract and applesauce. Set this mixture aside
In a large bowl add the almond flour, potato starch, arrowroot starch, baking soda, baking powder, and date sugar. Mix well, make sure date sugar is broken up well, it tends to have large lumps of sugar.
Add the Milk mixture and blend well.
Fold in the dates and walnuts and mix well. Do not over-mix.
Add mixture to bundt cake molds and distribute evenly. It will be overfilled since I want to create a seal at the bottom of the bundt cake.
Place bundt cakes in the oven and bake for 18 - 20 minutes or until toothpick comes out with a few crumbs. Do not overbake or the cake will come out dry.
Let cool for 15 - 20 minutes
Gently insert a knife into the sides of the bundt cake molds to loosen the cake from the mold. Place a wire rack on top and flip mold to remove cakes.
Let cool for 20 - 30 minutes.
