Preheat oven to 350°F (175°C).
In a mixing bowl, combine cooked quinoa, grated carrots, almond flour, maple syrup, eggs, vanilla extract, cinnamon, baking powder, and salt. Mix well.
Pour the mixture into a greased baking pan and spread evenly.
Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
While the bars are baking, prepare the frosting by mixing the cream cheese, powdered sugar, and vanilla extract until smooth.
Once the bars are cool, spread the frosting evenly over the top.
Cut into bars and serve.
