Blend The Oats. Start by blending the oats into an oatmeal flour. Put oats into your blender and puree until a fine powder.
Combine The Rest of The Ingredients. Scrape down the sides of the blender and add milk, pumpkin puree, eggs, syrup, butter or oil, apple cider vinegar, vanilla, baking powder, baking soda, salt, cinnamon. and nutmeg. Puree 20-30 seconds, or until fully combined and evenly blended. Pause to scrape down the sides of the blender, as needed.
Let mixture rest for about 5 minutes while you heat a large skillet over medium-low heat. Grease the skillet with a little extra butter, ghee, oil, or cooking spray.
Cook The Pancakes. Scoop or pour the batter into skillet (I use a 1/4 cup measuring cup for this). Cook pancakes 3-5 minutes, or until bubbles form on the surface. Flip pancakes and cook another 1-2 minutes or until deep golden brown on the outside and cooked through on the inside. Repeat with remaining batter. If your pancakes are having a tough time cooking through or are coming out too thick, add an additional splash of milk to the batter.
Serve & Store. Enjoy pancakes warm with syrup, toasted pecans, a dollop of yogurt, or your favorite toppings. Store leftover pancakes in an airtight container in the fridge 2-3 days.
