Preheat the oven to 350F. Line a 9x5 inch loaf pan with parchment paper.
In a small bowl, assemble the cinnamon swirl. Mix the almond flour, tapioca flour, walnuts, melted butter, cane sugar, salt, and cinnamon. Set it aside.
Blend the cottage cheese until smooth. In a large bowl, whisk it with the eggs, maple syrup, and vanilla.
In another bowl, stir together the almond flour, tapioca flour, baking powder, and salt. Add it to the wet ingredients and mix until you have a thick batter.
Spread half of the batter in the loaf pan and level it out. Sprinkle half of the cinnamon mixture on top and press it in.
Repeat with the rest of the batter and the rest of the cinnamon mixture.
Bake in the oven for 30 minutes. Then, cover with foil and bake for another 25-30 minutes until a toothpick comes out clean.
Let it cool down completely before slicing. It needs that time to set, and a warm loaf will fall apart on you out of spite.
