For extra fluffy pancakes, make sure your baking powder is fresh and avoid overmixing once the batter has thickened. Keep the heat at medium-low so the pancakes cook through without burning on the outside, and resist flipping them too early so they hold their shape. To make savory pancakes, omit the sweetener and vanilla, add an extra 1/4 teaspoon of salt and some chopped fresh herbs, and serve with smoked salmon or bacon. Cooled pancakes can be stored in an airtight container in the refrigerator for up to 4 days or frozen in a single layer, then transferred to a freezer bag for up to 1 month. Reheat gently in a skillet or toaster oven for the best texture.
