Combine dry ingredients: flour, sugar, baking powder, baking soda, and salt. Mix them together using a whisk to break up any clumps. Set aside.
Melt butter in the microwave -approximately 30 seconds. Set aside and allow to cool. When butter is cooled, combine with other wet ingredients: egg, milk, and vanilla bean paste. Combine until well mixed.
Mix dry ingredients with wet ingredients. Combine with a whisk, but do not overmix. If the batter is too dry, add extra milk. Set aside at least 30 minutes.
Heat a skillet on medium. Add in oil. When the oil becomes somewhat shimmery and loose, use a clean paper towel to wipe off excess oil. Then turn heat to low. Add in a ladle or 1/4 cup of pancake batter into the pan. After about 1 minute, when the surface of the batter begins to bubble, flip your pancake onto the other side. Allow to cook another 10 seconds, and then remove from the pan. Repeat until you have finished the batter.
