In a small saucepan, heat the plant-based milk and dairy-free butter until warm (about 110°F). Remove from heat and sprinkle the yeast over the mixture. Let it sit for 5-10 minutes until foamy.
In a large bowl, whisk together the flour, granulated sugar, and salt.
Add the yeast mixture to the dry ingredients, mixing until a soft dough forms.
Turn the dough out onto a floured surface and knead for about 5-7 minutes, until smooth and elastic.
Place the dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for about 1-2 hours, or until doubled in size.
