Rinse the uncooked quinoa under cold water in a fine-mesh strainer to remove any bitterness.
In a medium saucepan, combine rinsed quinoa and 1 cup water. Bring to a boil, then reduce heat to low, cover and simmer for about 15 minutes until quinoa is fluffy and water is absorbed.
In a large mixing bowl, whisk together unsweetened vanilla almond milk, unsweetened regular almond milk, honey, beaten eggs, and melted coconut oil until well combined.
In another bowl, mix almond flour, slivered almonds, 1/2 teaspoon cinnamon, and salt to combine flavors and texture.
Once cooled slightly, add cooked quinoa to the wet mixture, then fold in dry ingredients, chopped dates, and thick banana slices gently to maintain shape.
Preheat oven to 350°F (175°C). Grease a 9x9 inch baking dish with coconut oil. Pour quinoa mixture into dish and spread evenly. Sprinkle 2 tablespoons coconut sugar on top.
Bake for 30-35 minutes until top is golden brown and set in center; a toothpick inserted should come out clean.
Allow to cool for a few minutes before slicing. Serve warm or at room temperature and enjoy.
