Preheat oven to 350 degrees Fahrenheit and line a 1 lb loaf pan with parchment paper.
Add the coconut sugar, maple syrup, coconut oil (or apple sauce), soy milk, apple cider vinegar, vanilla and pumpkin to a bowl and whisk to combine.
Add the remaining dry ingredients and use a fork or whisk to combine, being sure not to overmix.
Transfer the mixture to the baking pan.
In a separate bowl, combine the ingredients for the crumb topping using a fork until it's crumbly. Sprinkle on top of the loaf and gently pat down.
Transfer to the oven and bake for 50-55 minutes until an inserted toothpick comes out fairly clean.
Let cool for at least 15 minutes before slicing into 1" thick pieces. Serve warm, topped with vegan butter.
