Preheat oven to 350 degrees. Grease a 9×5 loaf pan and cut a piece of parchment paper to fit inside the pan (for easy clean up and to help remove the bread from pan).
Place almond butter, pumpkin, banana, maple syrup, eggs pumpkin pie spice, coconut flour, baking soda, baking powder and salt in a food processor and puree until smooth. Wipe down sides of food processor if needed and puree once more.
Pour mixture into bread pan and smooth out.
In a small bowl, add butter, coconut sugar, almond flour, pumpkin pie spice, and walnuts. Use your hands to mix the toppings together until combined.
Place chunks of the toppings all around the top of the pumpkin bread mixture.
Bake in oven for 1 hour.
Mix together coconut milk, coconut sugar, and maple syrup. I heated mine up in the microwave but feel free to heat over a stove top.
