Preheat the oven to 350°F (175°C).
In a mixing bowl, thoroughly mash the bananas with a fork until smooth.
Use very ripe bananas for natural sweetness. No added sugar is needed.
Add the eggs, skyr, cooked quinoa, olive oil, baking powder, vanilla extract, cinnamon, and salt. Mix until fully combined.
Gently fold in the blueberries.
Frozen blueberries work just as well; no need to thaw.
Line a 9.5 x 8.5-inch (24 x 21 cm) baking tray with parchment paper or lightly grease it. Pour the mixture into the tray and spread evenly.
Bake for 40–45 minutes, until the top is golden and the center is set.
Remove from the oven and let cool for at least 10–15 minutes before slicing.
Slice and enjoy!
Enjoy as is, or serve warm with a drizzle of honey, a dollop of yogurt, or a spoonful of blueberry jam for extra flavor.
Store in an airtight container in the fridge for up to 4 days. It's perfect for meal prep.
