To a large mixing bowl or stand mixer bowl, add the flour, brown sugar, yeast, cinnamon, ginger, cloves, allspice, nutmeg, and salt. Mix that together.
Add in the warm milk, pumpkin puree, softened vegan butter and vanilla. Combine with a spatula or turn on the mixer until a dough forms.
Remove the dough ball from bowl. Grease the bowl well and then place the dough back into the bowl.
Cover and let rise for 45-60 minutes or until doubled in size.
Once doubled, punch down dough and then pull off pieces (about 2.5 to 3oz- use a scale if you want, but it's not needed).
Roll into balls.
Place each ball, seam side down, into a greased 9x13 baking pan.
Cover pan and let rise for another 30 minutes. *After this rise, you want the dough balls to slightly be touching each other. If they are not touching, give them a little bit longer. Preheat the oven to 375 degrees while rising this second time.
Using ⅓ cup of melted butter, brush each roll liberally.
Toss in oven 375 degrees for 18-20 minutes or until golden brown.
Remove from oven. Right before serving brush with remaining ⅓ cup melted butter again.
Best served warmed. Makes 16 dinner rolls.
