(If you'll be using an electric griddle to cook the pancakes, start preheating it now to medium heat. I set mine to 325°F.)
In a medium mixing bowl, whisk together the flour and baking powder. Set aside.
1 cup (120g) all-purpose flour, 2 teaspoons baking powder
To a blender, add the cottage cheese, eggs, maple syrup and vanilla. Blend until smooth.
1 ½ cups (339g) cottage cheese, 4 large eggs, 2 tablespoons pure maple syrup, 1 teaspoon vanilla extract
Pour the wet ingredients from the blender into the dry, scraping out as much as you can from the blender. Use a rubber spatula to gently mix the batter together until just combined. Do not over-mix. (The batter will be thick and airy.)
Heat a skillet or electric griddle over medium heat. Add a pat of butter to the pan. Once melted, spread the butter around the skillet.
Scoop the pancake batter onto the griddle, using about 1/4 cup of batter per pancake. Let pancakes cook on the first side until bubbles form and the pancake bottoms are golden, about 3 minutes. Flip the pancakes and cook them on the second side until golden, about 2 minutes. Repeat with remaining batter, adding more butter to the skillet to cook each batch of pancakes.
Serve pancakes with butter and maple syrup, if desired.
