To make this pumpkin streusel loaf, start by preheating your oven to 350F. Line a 9x5-inch loaf pan with parchment paper and set it aside.
In a large mixing bow, whisk together the maple syrup, melted coconut oil, pumpkin puree, eggs, and vanilla extract until smooth.
In a separate bowl, combine the gluten-free flour, baking soda, salt, and pumpkin pie spice.
Pour the wet mixture into the dry ingredients and use a spatula to gently fold until you no longer see streaks of flour. Transfer the batter into the prepared loaf pan and spread it evenly.
Next, make the streusel topping. Add the flour, coconut oil, pumpkin pie spice, and coconut sugar to a small bowl and use your hands to mix. You want it to be clumpy; if it's too dry, add a bit more coconut oil.
Spread the streusel evenly over the batter, covering the top completely.
Bake for 50-52 minutes, or until a toothpick inserted in the center comes out clean.
Make the glaze by whisking together powdered sugar, pumpkin spice, and water in a small bowl until smooth. Drizzle it generously over the top of the loaf once it's completely cooled.
Slice into 12 pieces and enjoy!
