Preheat oven to 356F (180C) and prepare a 9.5-in bundt cake pan (grease and dust flour through it, making sure to remove excess flour or use a thin layer of cooking spray).
Add the sugar, oil, carrots (peeled /diced) and eggs to a blender and blend until very smooth. Scrape down the sides as needed(no pieces of carrot should remain).
In a large bowl, add the sifted flour and pour the blended wet ingredients and whisk until fully incorporated.
Add the baking powder and gently whisk (do not overmix!).
Pour the batter into the prepared pan and bake for about 45-50 minutes, until a cake tester/toothpick comes out lightly crumbly to clean.
Remove the cake from oven, let it cool 15 minutes and unmold.
While the cake cools, choose the chocolate frosting from the options below!
