Preheat the oven to 175°C.
Prepare a loaf pan to bake the pumpkin bread in. Either grease the pan or line with parchment paper.
Combine all of the ingredients for the streusel in a small mixing bowl and set aside. This will allow the flour to absorb the other ingredients.
Mix all of the dry ingredients for the loaf in a medium mixing bowl. Set aside.
Mix the wet ingredients in a smaller mixing bowl. Make sure they are all room temperature because they combine best that way. When the wet mixture is combined properly, pour the wet into the dry ingredients and mix until just combined. Be careful not to overmix because then you make the loaf much more dense! :) You can do a taste test at this point and add in any more spice/sweetness if you wish!
Pour the batter in the loaf pan and sprinkle the streusel evenly over the whole loaf. Bake for 55 minutes to 1 hour, depending on your oven. You can check the loaf at about 35-40 minutes theorugh the oven window to see if it's getting too much colour. If it is, you can cover it with aluminum foil.
When a testing knife comes out almost clean, the loaf is done! Remove from oven and let the loaf cool in the pan for about 5 minutes but then let it cool the rest on a cooling rack.
Enjoy!!! :)
