01 - Preheat oven to 375°F. Line a standard 12-cup muffin tin with paper liners or lightly grease with oil.
02 - In a large mixing bowl, whisk together pumpkin purée, eggs, maple syrup, and olive oil until smooth.
03 - Add whole wheat flour, pumpkin pie spice, baking soda, and salt to the wet mixture. Stir gently until just combined; do not overmix.
04 - Evenly distribute the batter into prepared muffin cups, filling each about two-thirds full. Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.
05 - Allow muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely before serving.
