Preheat oven to 350F.
In a mixing bowl, whisk together your dry ingredients (flour, baking powder and salt).
Add in your wet ingredients (both sugars, flax egg, non-dairy milk, oil and vanilla). Mix until just combined.
Gently fold in your toppings of choice, if any. Be careful not to overmix here.
Grease your muffin tins with baking spray, non-dairy butter or just use muffin liners!
Fill your muffin tins about 3/4 full. An ice cream or cookie scoop will help make them all even.
Bake for 10 minutes, rotating your pan halfway through baking.
Allow to cool for a few minutes in the pan. Then, carefully remove onto a cooling rack and enjoy!
