Preheat your griddle.
In a large mixing bowl, whisk together the dry ingredients: both flours, brown sugar, baking powder, baking soda, salt and cinnamon.
In a large measuring cup, whisk together milk, vinegar, pumpkin puree, oil and vanilla. Add to the dry ingredients and whisk until the batter is thick and light. It should look like it has air pockets.
Using 1/4 cup of batter at a time, fry pancakes on one side until bubbles form around the edges. Flip and fry 1 more minute. Repeat util you use up all of the batter.
Serve warm, with fresh berries, sliced bananas, chopped nuts, coconut flakes and a drizzle of honey or pure maple syrup.
