Preheat the oven to 350°F (180°C). Line an 8x4-inch (20x10 cm) loaf pan with parchment paper.
In a large bowl, whisk together the pumpkin puree, applesauce, eggs and almond butter until smooth.
½ cup pumpkin puree, 1 cup unsweetened applesauce, 2 eggs, ¾ cup almond butter
Add the diced apple, baking powder, cinnamon or pumpkin pie spice and flour. Stir with a spatula just until no dry flour remains.
1 apple, 1 tsp baking powder, 1 tsp cinnamon or pumpkin pie spice, ½ cup + 2 tablespoons all-purpose flour
Pour the batter into the prepared pan and smooth the top.
Bake for about 40 minutes, until a toothpick inserted in the center comes out clean.
Let the bread cool in the pan for about 10 minutes, then lift it out and let it cool completely before slicing.
