Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.

In another bowl, beat the eggs and sugars until well combined. Gradually add the oil and vanilla extract, mixing continuously.

Step 4

Stir in the grated carrots and apples to the wet mixture.

Step 5

Gradually add the dry ingredients to the wet mixture, stirring until just combined. If using, fold in the walnuts and raisins.

Step 6

Pour the batter into the prepared baking pan and spread evenly.

Step 7

Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.

Step 8

Let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
