Preheat oven to 400ºF. Line a 12-cup muffin tin with paper liners and set aside.
Whisk together the 2 C flour, baking powder, baking soda, and salt in a bowl. In a separate bowl, mix together the bananas, olive oil, maple syrup, almond milk, and vanilla.
Next, thoroughly combine the dry and wet ingredients. Toss and coat the dates with 1 tbsp flour. Roughly chop the pepitas. Gently fold the dates and pepitas into the batter. Evenly divide the batter among the muffin tin cups and sprinkle each one with a few pepitas. Bake for 20-25 minutes, until muffins are brown and a toothpick comes out clean.
