Make the Pumpkin Spice Streusel:

1. In a small bowl, mix together the streusel ingredients and refrigerate while preparing the pumpkin bread.

Make the Pumpkin Bread:

1. Preheat the oven to 325°F (or 350°F depending on your oven calibration—see notes). Grease a 9×5-inch loaf pan and line with parchment paper for easy removal.
2. In a medium bowl, whisk together the dry ingredients: flour, baking soda, cinnamon, pumpkin pie spice, and salt. Set aside.
3. Using an electric mixer (or whisk), combine the granulated sugar, brown sugar, pumpkin puree, and oil until fully incorporated. Add in the eggs and vanilla extract, mixing until smooth.
4. Gradually mix in half of the dry ingredients, followed by the milk, and then the remaining dry ingredients. Mix until the batter is smooth.
5. Pour the batter into the prepared loaf pan and smooth the top.

Add the Streusel:

1. Remove the streusel from the fridge and break it into small crumbles with a knife or fork. Sprinkle it evenly over the top of the batter.
2. Bake the bread for 1 hour and 20 minutes or until a toothpick inserted in the center comes out clean. If needed, continue baking in 5-minute increments.

Make the Maple Glaze:

1. While the bread bakes, whisk together the powdered sugar and maple syrup until smooth.

Glaze the Bread:

1. As soon as the bread is out of the oven, drizzle the maple glaze over the hot loaf. Let the bread cool for 20 minutes in the pan before lifting it out using the parchment paper.
2. Slice and enjoy warm or store in an airtight container in the fridge.
