Preheat oven to 350℉ and line a muffin tin with silicone muffin liners or regular muffin liners.
Combine the soy or nut milk and apple cider vinegar or lemon juice and set aside to make “buttermilk” for 10 minutes.
In a large bowl, add the avocado oil, honey, eggs and vanilla, and mix on medium using a handheld mixer or stand mixer with a paddle attachment for 1 minute until silky smooth.
Pour in the “buttermilk” and mix for another 10 seconds until well combined.
Sift in the flour, baking powder, baking soda and salt. Mix until well combined, do not overmix.
Pour or scoop the batter into lined muffin tin, filling each ½ to ⅔ of the way full. I recommend using silicone reusable baking cups or recycled paper liners. Bake for 22 to 25 minutes until tops of the cupcakes are lightly golden and a toothpick inserted in the center comes out clean. Allow to cool in the pan for about 5 minutes before removing and transferring to wire rack. Enjoy!
Store any leftover cupcakes in an airtight container in the refrigerator for up to 2 days.
