Melt the vegan butter for 30 seconds in the microwave. Let it cool down. Take the applesauce out of the refrigerator (if it's refrigerated) so it can start to come to room temperature.
Make the vegan buttermilk by stirring the apple cider vinegar into the soy milk. Let it sit for 3-4 minutes so it can curdle.
In a large bowl, whisk the flour, cane sugar, baking powder, baking soda, and salt together really well.
Pour the melted vegan butter, applesauce, and vanilla into the vegan buttermilk. Stir them together, then pour this into the dry-ingredient bowl.
Very gently, stir them together just until you don't see any streaks of flour. Try not to overmix the batter. It's okay to see lumps here.
Let the batter sit for a few minutes so it can come together. Meanwhile, heat your pan or griddle up to medium heat. I find the sweet spot to be just below medium.
Once heated, coat the pans with a small amount of vegan butter or oil. Pour ⅓ cup portions of batter starting from the center to form a circle. Be sure to leave yourself enough room to flip them.
Cook them for 2-3 min on each side or until they're golden brown. Flip them when bubbles rise to the top of the batter and pop. Try to flip them just once to keep them fluffy. Tip: use a very thin, wide spatula. It's okay to peak underneath so you don't over-flip them.
Add more vegan butter to the pan and repeat these steps until you're out of batter. You should have 10 pancakes. Enjoy with your favorite toppings such as maple syrup and fresh fruit!
