Start by preheating your oven to 350 degrees. Grease a bundt pan with cooking spray and set it aside.
Get a gallon zip lop bag or medium bowl and place ½ cup white sugar, ¼ cup brown sugar, cinnamon, ginger, and nutmeg, close the bag and shake to combine, and set aside.
Take your biscuits out and cut each biscuit into 4 even pieces, when they are all cut throw all the pieces into the sugar mixture zip lock bag and shake away. Try to separate pieces if you need to, to fully coat each piece.
Once everything is coated go ahead and pour the bag evenly in the prepared bundt pan.
Take a medium liquid measuring cup and melt your vegan butter then add your brown sugar, and milk if using and stir until combined.
Pour this mixture evenly over into the bundt pan. Bake in the preheated oven for 30-45 minutes until the biscuits are done, make sure to dig a toothpick in there to make sure it's actually cooked. If it starts browning too soon for your taste you can throw some foil for it.
Once it's cooked let it sit in the pan for about 15- 20 minutes before flipping it onto a plate.
Make your cinnamon icing by combining your icing ingredients and stirring until combined. Drizzle this over the monkey bread, you can save some and drizzle it over each serving.
