Preheat the oven to 350F / 176 C. Line a 9”x5” inch loaf pan with parchment paper, letting the paper extend by a few inches to make it easy to remove the cake.
In a medium bowl, whisk together the applesauce, maple syrup, coconut sugar, almond butter, almond milk and vanilla extract until smooth.
In a large bowl, combine 1¾ cups of the spelt flour, the rolled oats, cinnamon, baking powder, ginger, nutmeg, allspice, baking soda and salt.
Pour the wet ingredients into the dry, stirring to combine with a wooden spoon until well incorporated.
In a small bowl, combine the blueberries with the remaining 2 tablespoons spelt flour, tossing to coat (this prevents the blueberries from sinking to the bottom of the cake). Using a rubber spatula, fold the blueberries and chopped pistachios into the cake batter. Pour the batter into the prepared loaf pan.
Bake the loaf until a toothpick inserted into the center comes out clean, 55 to 60 minutes. Allow to cool in the pan on top of a wire rack, then lift the bread out of the pan using the parchment as handles. Serve warm or at room temperature.
