Preheat oven to 375°F. Line a 12-cup muffin tin with muffin liners and set aside.
In a large bowl, combine granulated sugar, eggs, dairy-free sour cream, vegetable oil, orange zest and vanilla extract. Beat until combined and smooth. In a seperate bowl, combine flour, baking soda and salt. Whisk to combine.
Add flour mixture to the liquid mixture and stir or blend until just combined. Fold in blueberries.
Fill lined muffin cups with batter ¾ full (a little more is ok) and sprinkle with the cane sugar. If you find you have extra batter, make 1-2 additional muffins rather than over-filling the cups. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the muffin tin for 10 minutes, then transfer to a cooling rack to cool completely.
