Peel the sweet potatoes and dice them into bite-sized cubes, place them into a large pot and cover them with water. Alternatively, you can steam them in a basket steamer.
Once the sweet potatoes are fork-tender, drain and transfer them to a large bowl. Then, use a fork, potato masher, or hand blender to mash the potatoes.
Start by adding 1 cup of flour to the sweet potatoes, mixing until all the flour is absorbed. Continue adding flour until you can form a ball of dough. The dough will be sticky but should have enough flour that you can handle it. As a guide, use equal amounts of sweet potatoes to flour.
Place the dough on a lightly floured surface. Add more dough if necessary until you can roll and handle it. Roll the pizza crust to about ¼ of an inch.
Preheat the oven to 400 F (200 C). Line a pizza pan or pizza stone with parchment paper and lay the pizza crust over it. You can adjust the shape as needed.
Bake the first side of the pizza crust for 10 -15 minutes until it is lightly browned.
Remove the pizza pan from the oven. Gently slide the pizza crust and the parchment paper onto a flat surface like a cutting board. Lay the pizza pan over the top and then flip everything over. Peel away the top layer of parchment paper.
Place the crust back into the oven and bake for another 5-10 minutes until it is crispy and brown.
Add sauce and toppings to your pizza and bake at 400 F (200 C) until the toppings are as done as desired. Cut the pizza into slices and enjoy!
