Combine cottage cheese, eggs, almond flour, baking powder, vanilla extract, sweetener, and cinnamon in a high-speed blender.
Process the mixture for 30 to 45 seconds until the batter is completely smooth and homogeneous.
Heat a non-stick skillet or griddle over medium-low heat and coat with a thin layer of butter.
Pour approximately 1/4 cup of batter onto the skillet for each pancake, leaving space for flipping.
Cook for 2 to 3 minutes until small bubbles form on the surface and the edges are firm.
Carefully flip each pancake using a thin spatula and cook for an additional 1 to 2 minutes until golden brown.
Serve immediately with sugar-free syrup or fresh berries.
