Preheat your oven to 350°F (or 425°F for the first 5 minutes if you want an extra bakery-style rise).
Grease and flour your 8x4 loaf pan (or 9x5, see “Size Matters” section). Make sure the corners are fully coated so your bread doesn’t stick.
In a medium bowl, whisk together 1 cup all-purpose flour, 1/4 tsp baking soda, 3/4 tsp baking powder, 1/2 tsp salt, 1 1/2 tsp cinnamon, 1/2 tsp nutmeg, 1/4 tsp ground ginger, 2 tsp pumpkin pie spice and 1/4 tsp cloves.
In a large mixing bowl, stir together 7.5 ounces pumpkin purée, 1/3 cup vegetable oil, 1/2 cup granulated sugar, 1/2 cup brown sugar, 2 large eggs, and 1 tsp vanilla extract.
Whisk until smooth and fully combined. The sugar dissolves and the eggs incorporate, giving the bread a soft, tender crumb.
Add the dry ingredients to the wet ingredients in two additions, folding gently with a spatula after each addition.
Stop mixing as soon as the flour disappears. Overmixing will make your bread dense.. and trust me, you don’t want that.
In a small bowl, mix 1/2 cup brown sugar, 4 tbl flour, 1 tsp cinnamon, 1 cup chopped pecans, and 4 tbsp melted butter.
Use a fork or your fingers to crumble it together. It should be clumpy, not paste-like.
Pour the pumpkin batter into your prepared pan and smooth it evenly.
Sprinkle your streusel over the top.
Place in the oven. For 8x4 pan, bake 50-55 minutes. For 9x5 pan, bake 45–48 minutes (see “Size Matters” section).
Be sure to tent lightly with aluminum foil half way through baking process to ensure your praline topping doesn't brown too much.
The loaf is done when a toothpick inserted into the center comes out mostly clean with a few crumbs.
Let the bread cool in the pan for 10–15 minutes, run a knife around the inside edge of pan to release the bread, remove from baking pan and then transfer to a wire rack.
Slice once fully cooled (or sneak a slice while still warm.. I won’t tell).
