Preheat the oven to 375℉/190℃ and line a muffin tin with muffin liners. Melt the coconut oil and allow it to cool as you prep the rest of the ingredients.
In a large bowl, combine the flour, baking soda, baking powder, cornstarch, and salt. Stir to combine and set aside.
2 cups all-purpose flour, 1 tsp baking soda, 2 tsps baking powder, 1/4 tsp salt, 1 tbsp cornstarch
In another large bowl, add the white sugar, coconut oil, oil, eggs, vanilla, coconut milk, and sour cream. Whisk to combine for 1-2 minutes or until well combined.
2 large eggs, 3/4 cups white sugar, 1/2 cup extra-virgin coconut oil*, 2 tbsp oil, 1/2 cup full-fat sour cream, 1/2 cup coconut milk*, 1 tbsp vanilla
Add in the dry ingredients and combine together just until a soft muffin batter forms - don't over-mix!
Mix in the mini chocolate chips and coconut a few times just until well combined. Don't over-mix!
1 1/4 cups unsweetened shredded coconut*, 1/2 cup mini chocolate chips
Scoop and fill the liners to the top. Sprinkle extra chocolate chips on top if desired (optional).
Bake for 23-28 minutes or until a toothpick inserted in the middle comes out clean. Allow to cool, and enjoy!
