Preheat your oven to 350°F (175°C) and grease a standard loaf pan.

In a large mixing bowl, blend the cottage cheese until smooth. Add in the eggs and maple syrup, mixing until creamy.

Gradually add oat flour, baking powder, cinnamon, and optional vanilla extract to the wet mixture. Stir gently until just combined.

Pour half of the batter into the prepared loaf pan. Sprinkle a layer of cinnamon sugar over it and then pour the remaining batter on top.

Gently swirl through the batter with a knife or skewer to create a marbled effect.

Bake for 45-50 minutes or until a toothpick inserted in the center comes out clean.

Let the bread cool in the pan for 10-15 minutes, then transfer to a cooling rack to cool completely before slicing.

Slice and serve your Cottage Cheese Cinnamon Roll Bread warm or with your favorite toppings.
