Combine the yeast, warm water and sugar/honey in a bowl. You want the water to be warm but not hot because it will kill the yeast. About 110 degrees Fahrenheit is ideal.
Stir and let sit.
Combine the rice flour, tapioca corn starch, baking powder, salt, psyllium husk powder and garlic powder in a large mixing bowl. Be sure to spoon and level the flours into the measuring cups, don't scoop right from the bag.
Pour in the water/yeast mixture, oil and apple cider vinegar.
Use a wooden spoon to mix until combined. If it seems dry at all, just add 1-2 tbsp more warm water as needed. it should resemble a standard pizza dough. If it cracks too much when you press down for kneading (a little cracking is ok) add a smidge more water.
Transfer to a clean surface and knead with your hands for 90 seconds. I suggest setting a timer because if you knead for too long it can make the dough gummy, but too little and it won't rise properly.
Transfer back to the bowl, cover with plastic wrap and let sit in a warm and dark environment for 90 minutes to 2 hours. If it's a cold day, preheat the oven to 110 Fahrenheit, turn it off and then the dough sit in the off oven. Otherwise, in a regular off oven or the warming drawer below the oven is perfect.
After about 90 minutes, the dough should roughly double in size.
Preheat the oven to 400 degrees Fahrenheit.
Transfer the dough to a piece of parchment paper and roll into about ¼-1/2 inch thick, creating a slight lip with the edge of the crust if desired. You can make it as thick or as thin as you like, just depends on your preference.
Brush lightly with olive oil and bake for 5 minutes once the oven has heated.
Remove from the oven, add sauce and desired toppings and bake for an additional 10-15 minutes. I topped mine with my homemade pesto, Miyokos Mozzarella, and then arugula, basil and parmesan after baking.
Remove from the oven, slice and serve warm. Enjoy!
