Whisk together milk and white vinegar. Set aside and allow to sit for about 10 minutes so it can “sour” the milk.
Whisk together flour, sweetener/sugar, baking powder, baking soda and salt.
In a separate bowl, whisk together egg, butter, and soured milk.
Combine the wet into the dry, and whisk to remove clumps.
Heat a skillet over medium high heat and spray it down with cooking spray. Add about ¼ cup of batter onto the skillet and allow to cook until bubbles appear on the edges. Flip with a spatula and cook until both sides are browned. Repeat for all pancakes!
