Preheat oven to 375°F and line a baking sheet with parchment.
In a large bowl, combine flour, baking powder, salt, cinnamon, and nutmeg.
In another bowl, mix the blended cottage cheese, Greek yogurt, maple syrup, vanilla, and shredded carrot.
Add the wet mixture to the dry and mix until a dough forms. Fold in raisins or walnuts if using.
Lightly flour your surface and knead the dough until smooth. Divide into 6 to 8 portions and roll into bagel shapes.
Place on the baking sheet, brush with egg wash, and top with desired toppings.
Bake for 25–28 minutes or until golden brown. Let cool before slicing
