Preheat your oven to 350°F (175°C). Line a muffin tin with liners or lightly grease it.
In a large bowl, combine the coconut sugar and oil and whisk to combine
Add in the pumpkin puree, eggs, vanilla extract, and cottage cheese and mix until well combined
In another bowl, whisk together the flour, baking soda, baking powder, pumpkin pie spice, and a pinch of salt
Gently add the dry ingredients to the wet mixture, stirring until just combined (be careful not to overmix)
Fold in the chocolate chips
Scoop the batter into the prepared muffin tin with a 3 inch cookie scoop, filling each cup about 2/3 full
Sprinkle the streusel topping on each muffin
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean
Allow to cool in the muffin tin for a few minutes before transferring to a wire rack to cool completely
