Preheat the oven to 350°F.
Spray a 9x13 inch metal pan with cooking spray and set aside.
In a blender, add the carrots, eggs, and oil. Blend until smooth.
Add the sugar and vanilla to the blender and blend until combined.
In a separate bowl, mix the flour, baking powder, and salt. Stir the dry ingredients into the wet mixture until evenly combined.
Pour the batter into the greased baking dish. Bake for about 40 minutes or until the top is golden and a toothpick inserted into the center comes out clean.
Remove from the oven and let cool to room temperature before adding the chocolate glaze.
