Before beginning to make the cake, preheat your oven to a temperature of 375 degrees Fahrenheit, which is equivalent to 190 degrees Celsius. After that, take a 9-inch circular cake pan and make sure to grease and flour it so that the cake doesn't stick to the pan.
Next, put some carrots, sugar, oil, and eggs into a blender and blend the ingredients together until the mixture is smooth. While still blending, gradually add some flour to the mixture until it's well blended. Once that is done, turn off the blender and stir in some baking powder using a wooden spoon. Take the cake pan you prepared earlier and pour the cake batter into it.
Put the cake pan with the batter into the preheated oven and bake until the center is fully cooked. You can check if the cake is done by inserting a toothpick into the center, and if it comes out clean, the cake is ready. The baking process should take around 30 to 40 minutes. Once done, remove the cake from the oven and place it on a wire rack to cool. After it has cooled completely, use a table knife to loosen the edges of the cake, and then carefully invert it onto a serving plate.
