Preheat the oven to 350F. Line a standard muffin tin with parchment muffin cups.
In a large bowl, whisk together the almond butter, olive oil, maple syrup, eggs, and vanilla until totally smooth (this will take about 30 seconds, get an arm workout in!).
Add the walnuts, hemp seeds (if using), spices, salt, and baking powder and mix until well combined. Stir in the apples.
Scoop the batter into the muffin cups, filling them just below the brim. Bake for 15-20 minutes (18 minutes was my sweet pot) or until no longer doughy. Don’t overbake!
Transfer to a cooling rack and let cool for at least 10 minutes.
