Stir flour, baking soda, cinnamon, and salt together in a large bowl.
Whisk cottage cheese, milk, eggs, and oil together in a separate bowl. Pour into the flour mixture; whisk until batter is just combined; it will be thick.
Heat an oiled griddle over medium-high heat; when a water drop on the surface dances and sizzles, it's ready. Drop 1/4 cup batter onto the griddle. Cook until golden brown and bubbles break the surface, 1 to 2 minutes. Turn and cook until set, about 1 minute more. Repeat with remaining batter.
