Combine the sugar, eggs, bananas, and oil in the base of a stand mixer and mix on medium until well combined. Add the vanilla and quinoa and mix for 10 seconds.
Combine the remaining dry ingredients in a small bowl and stir to combine, then add to the mixer on low just until incorporated; do not overmix.
Line a muffin tin with liners and portion batter into 18 muffins. Bake at 375 degrees until lightly browned a toothpick inserted into the center comes out clean, about 13-15 minutes. Let cool before storing in a covered container; freeze well!
