In a blender or food processor, blend 1 cup cottage cheese, 2 teaspoons vanilla extract, and 2 teaspoons apple cider vinegar until smooth.
In a large bowl, combine 1-1/4 cups oat flour, 1 cup almond flour, 1/2 cup tapioca flour, 1 tablespoon baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt, and 2 tablespoons cane sugar. Add the blended cottage cheese mixture and mix with a hand mixer or sturdy spatula until a slightly sticky dough forms.
Spray a sheet of parchment paper and your hands with non-stick spray. Spread the dough into a rectangle about 1/4-inch thick. Spread 1/4 cup softened butter evenly across the dough.
In a small bowl, stir together 1/3 cup coconut sugar, 2 teaspoons cinnamon, and 1/4 teaspoon salt. Sprinkle over the buttered dough and press gently to adhere.
Slowly roll the dough using the parchment paper to guide it. Gently peel the dough from the paper as you go. Slice into 12 rolls using dental floss or a sharp knife.
Place rolls in a greased baking dish. Bake at 350°F for 22–25 minutes, or until lightly golden.
