Combine 1/4 cup of warm coconut milk (not boiling) with maple syrup in a small bowl. Add yeast and stir. Wait about 5 minutes for the mixture to start foaming and bubbling. (If the yeast doesn't foam, throw it away and start over.)
Meanwhile, combine the dry ingredients in a large bowl. Mix well with a spatula and form a well in the middle.
Add the yam, coconut oil and yeast mixture then stir with a spatula to combine.
Then make the gelatin egg by combining the water and gelatin. Whisk until frothy then carefully pour into the bowl. Continue mixing with a spatula until dough is smooth. Then form the dough into a ball.
Line a baking sheet with parchment paper. Brush the parchment with olive oil. Transfer the dough to the parchment. Flatten with your hands to form a 1-inch-thick 10-inch round pizza crust. Cover with a light, clean kitchen towel and let rest in a warm place for 30 minutes.
Place the oven rack in the middle position and preheat the oven to 375 degrees. Place the baking sheet in the oven as well.
After 30 minutes, uncover the dough, brush the crust with olive oil and add your pizza toppings.
Bake for about 12-15 minutes, until the bread is cooked through, crisp on the outside and slightly browned. Let cool slightly before eating.
