Preheat the oven to 375 degrees and grease a standard 12 muffin pan.
In a medium bowl, whisk together the gluten free four, baking soda, cinnamon, and salt.
In a large bowl, mix eggs, maple syrup, vanilla extract, coconut oil, and oat milk. Add they dry ingredients, and stir to combine. Stir in the crushed pineapple, carrots, apples, and raisins.
Transfer the batter to the muffin pan, filling to the top of each muffin cup. Bake for 20 to 22 minutes, or until golden on top and a toothpick inserted in a muffin comes out clean.
Cool on a wire rack in the pan for 15 minutes, then remove the muffins from the pan to cool completely. Store these muffins in an airtight container at room temperature for up to 3 days, or freeze for later.
