Preheat oven to 350º.
Mix all streusel ingredients well and set aside.
Beat eggs, then add pumpkin, coconut milk and melted coconut oil. Beat again.
Mix dry ingredients in a separate bowl, then add to wet ingredients and stir until well combined.
Pour batter into a greased loaf pan. Spread evenly with a rubber spatula, then add streusel topping.
Bake for 55-60 minutes, or until a toothpick inserted in the center of the loaf comes out clean.
