Blend the cottage cheese, eggs, milk, vanilla extract, and cookie butter until smooth.
Whisk the oat flour, protein powder, baking powder, cinnamon, ginger, and salt in a large bowl.
Stir the blended cottage cheese mixture into the dry ingredients until just combined. Let the batter rest for 5 minutes.
Heat a lightly buttered nonstick skillet over medium-low heat. Cook the pancakes in 1/4 cup portions until bubbles form and the edges look dry.
Flip the pancakes and cook for 1 to 2 minutes more, then repeat with the remaining batter.
Whisk the Greek yogurt, cookie butter, and milk together until creamy and smooth.
Spread the cookie butter cream over the pancake stack, then add the crushed cookies and melted cookie butter.
