Mix all the ingredients with a fork until crumbly. Set aside.
For the Loaf
Add the pumpkin puree to a cheese cloth over a cup or bowl and squeeze to remove most of the liquid. You can also do this with paper towels or a fine mesh strainer. Save the pumpkin juice!
Preheat the oven to 350°
In a large bowl, add the strained pumpkin puree, sugar, melted butter, oil, eggs & vanilla. Whisk well.
Using a spatula, stir in the remaining dry ingredients. Fold until no pockets of flour remain. The batter will be thick.
Pour into a prepared loaf pan and top evenly with your crumb. Bake for 1 hour or until the center is set. Allow the loaf to cool before glazing. Slice and enjoy!
For the glaze
Add the sifted powdered sugar to a bowl, along with the rest of the ingredients. Whisk until smooth an no longer lumpy. Set aside until ready to use. When ready whisk again before pouring over the top of the loaf.
