Add the lukewarm water and yeast to a mixing bowl and let sit for 5-10 minutes to activate the yeast. Then, add in the melted vegan butter, sugar, vanilla, and mix together.
Next, add the flour, cinnamon, and salt and mix together until a thick yet shaggy dough forms.
Once the dough has formed, it’s time to knead the bread. If you are using a standing mixer, use the bread hook to knead the dough until it is elastic and no longer sticking to the sides of the bowl (about 5-6 minutes). If you are kneading by hand, add the dough to a well-floured surface and knead for 8-10 minutes. The dough is done kneading when it is smooth and tacky, but not super sticky, and can be easily stretched without tearing.
When the dough is elastic and well-kneaded, form into a round ball. Place the dough into a well-oiled bowl. Then, cover the bowl with plastic wrap or a towel and it let rise for about 1 hour until the dough has doubled in size.
