Preheat the oven to 350 F and line a muffin pan with 12 parchment liners.
Add the oats to a high speed blender and pulse until it turns into a 'flour.' Add in the eggs, pumpkin puree, cottage cheese, protein powder, baking powder, baking soda and spices (and sugar, if using!) and blend until creamy and smooth. You may need to use a spatula to scrape the sides to ensure the batter has fully mixed.
Use a spatula to stir in the chocolate chunks, then pour evenly into the 12 parchment-lined muffin tins. Option to top each with 2-3 chocolate chunks.
Bake for 20 minutes, until the tops are golden brown and a toothpick comes out clean.
Option to top with flaky sea salt and enjoy!
