Step 1: Preheat the oven

• Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease the cups well.

Step 2: Mix the dry ingredients

• In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking soda, cinnamon, and salt.

Step 3: Combine wet ingredients

• In a separate bowl, whisk together the vegetable oil, eggs, and vanilla extract until well combined.

Step 4: Mix the batter

• Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Do not overmix.

Step 5: Fold in the mix-ins

• Gently fold in the grated carrots, grated apple, shredded coconut, chopped nuts, and raisins (if using).

Step 6: Fill the muffin tin

• Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full.

Step 7: Bake the muffins

• Bake for 25–30 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Step 8: Cool and serve

• Allow the muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely. Serve warm or at room temperature.
