Follow these steps to create your delicious Carrot Cake Cupcakes:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with paper cupcake liners.
2. Mix Dry Ingredients: In a large bowl, combine the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg. Whisk together until well blended.
3. Combine Wet Ingredients: In another bowl, whisk together the vegetable oil, eggs, and vanilla extract until fully combined.
4. Add Carrots: Stir the grated carrots into the wet ingredients until they are evenly coated.
5. Combine Mixtures: Gradually add the wet mixture to the dry ingredients. Stir gently until just combined. Be careful not to overmix.
6. Add Nuts and Raisins: If desired, fold in the chopped walnuts or pecans and raisins until evenly distributed.
7. Fill Cupcake Liners: Using a scoop or spoon, fill each cupcake liner about 2/3 full with the batter.
8. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Remove the cupcakes from the oven and allow them to cool in the tin for about 10-15 minutes. Then, transfer them to a wire rack to cool completely.
10. Frost: Once cooled, frost the cupcakes with cream cheese frosting or your favorite topping.
