Preheat your oven to 350°F (175°C). This ensures that your cake bakes evenly.
Grease your 9x13 inch baking pan with butter or non-stick spray. This will help the cake come out easily once baked.
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, ground cinnamon, baking powder, and baking soda until well combined.
In another bowl, combine the vegetable oil and eggs. Whisk until the mixture is smooth and fully blended.
Gradually add the wet ingredients to the dry ingredients, stirring gently. Be careful not to overmix! Fold in the finely shredded carrots and chopped pecans until just combined.
Pour the batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a cooling rack to cool completely.
While the cake cools, beat together the softened cream cheese and salted sweet cream butter in a mixing bowl until creamy. Gradually add the powdered sugar and clear vanilla flavoring, mixing until smooth and fluffy.
Once the cake is completely cooled, spread the cream cheese frosting evenly over the top. For an optional touch, sprinkle additional chopped pecans on top for garnish.
