Add the oats, egg whites, cottage cheese, pumpkin puree, maple syrup, and pumpkin pie spice straight into your blender. Blend on high until the mixture turns smooth and slightly thick, with no visible oat chunks left behind. It should look like a traditional pancake batter, just a bit heartier.
Place a nonstick skillet over medium heat and let it warm up for a minute or two before you start cooking. Lightly coat the surface with a little coconut oil or cooking spray so nothing sticks. A properly heated pan makes a huge difference in how evenly these cook.
Pour small, round scoops of batter onto the hot skillet, leaving a little space between each one. Let them cook undisturbed until you see bubbles forming around the edges, which usually takes about two to three minutes.
Once the edges look set and slightly golden, gently flip each pancake with your spatula. Cook the other side for another two minutes or so, until both sides are golden brown and the center is fully cooked through.
Stack your finished pancakes on a plate while they're still warm. Top them with whatever you're in the mood for, whether that's a drizzle of maple syrup, a spoonful of nut butter, or a handful of chopped walnuts.
