Add the softened cream cheese, whole eggs, almond milk, sugar-free sweetener, and vanilla extract directly into a high-speed blender or food processor. Blend on medium speed for 30 seconds until the liquid baseline is completely smooth, pale, and free of cheese lumps.
Pour the blanched almond flour, baking powder, and salt into the blender. Secure the lid and pulse on high for 30 to 45 seconds just until a thick, uniform pancake batter forms. Let the batter rest undisturbed inside the blender jar for 2 to 3 minutes; this pause allows the leavening agents to activate and puff up the mixture.
Melt a tiny pat of unsalted butter in a large non-stick skillet or flat griddle set over medium-low heat.
Pour the batter onto the hot surface in small 4-inch rounds (about 3 to 4 tablespoons per pancake). Keeping keto pancakes relatively small ensures they are stable and easy to flip without tearing.
Cook undisturbed for 3 to 4 minutes over a steady, low flame. Because almond flour lacks gluten, you won't see as many surface bubbles as traditional batter; look instead for the outer borders to turn matte and look slightly dry.
Slide a thin, wide spatula completely beneath the pancake and flip it over in one quick motion. Cook the second side for an additional 2 minutes until both surfaces are a beautiful golden brown and the center feels springy to the touch.
Transfer the hot pancakes to a plate and repeat the cooking process with the remaining batter, adding a tiny smear of fresh butter to the pan between batches. Serve immediately while warm with sugar-free maple syrup or fresh berries.
