Add the cottage cheese, pumpkin puree, maple syrup, pumpkin pie spice, vanilla and salt to a blender.
Blend on high for 1 to 2 minutes, scraping down once, until completely smooth with no curds left. Taste and add a little more maple or spice if you like.
Pour into a loaf pan lined with parchment and spread it flat.
Freeze for 2 1/2 to 3 hours, stirring well every 45 minutes for the first 2 hours so it stays creamy.
Meanwhile, toast the pecans in the butter in a small skillet over medium-low heat for 3 to 4 minutes until fragrant. Sprinkle with cinnamon and let cool.
Scoop into bowls and top with the pecans. If frozen solid, let it sit on the counter for 15 to 20 minutes first.
