Preheat oven to 350°F and line a 12-cup muffin tin.
In a large bowl, whisk together oat flour, baking powder, baking soda, cinnamon, ginger, nutmeg, cloves, and salt.
In another bowl, whisk eggs, maple syrup, molasses, blended cottage cheese, butter, and vanilla until smooth.
Gently fold wet ingredients into dry until just combined. Batter will be thick but spoonable.
In a small bowl, combine streusel ingredients with your fingers until crumbly.
Divide muffin batter evenly among cups, then sprinkle each with streusel.
Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
Cool slightly before serving.
