Some yogurts are more watery than others and cause the 2 Ingredient Dough to be a little sticky. If your 2 Ingredient Dough is sticky as you're rolling it, here's a helpful tip: You can add extra flour until the dough isn't sticky. If you're using a rolling pin on the dough (to use it for something like homemade pizza dough), you'll want to add a little extra flour to the rolling pin before rolling. If not, the dough can stick to the rolling pin. Add a little at a time. You can add up to 1/4 cup of extra self-rising flour without changing how it bakes. Any more than that might make the dough too dry.
