Preheat your oven to 350°F and line a muffin tin with 10-12 muffin cups.
To a blender, add the diced apples, eggs, rolled oats, olive oil, maple syrup, baking soda, baking powder, vanilla, cinnamon, ginger, nutmeg, and kosher salt.
Blend on high for 1-2 minutes until smooth and creamy.
Let the batter sit for 5 minutes. During this time, grate your carrots if you haven't already.
Fold in the shredded carrots and raisins gently using a spatula.
Divide the batter evenly among the muffin cups, filling each nearly to the top for taller muffins.
Sprinkle a few additional oats on top for texture, if desired.
Bake for 28-30 minutes, or until a toothpick inserted in the center comes out clean.
Remove the muffins from the tin and let them cool on a wire rack for 5-10 minutes before serving.
