Note: This recipe requires three mixing bowls, one for the dry ingredients, one for the wet ingredients, and a third to beat the egg whites.
To begin, preheat the griddle. Then, whisk the flour, sugar, salt and baking powder together in a large mixing bowl.
Separate the eggs. Add the egg yolks into one mixing bowl and the egg whites into another.
Beat the egg whites until you have soft peaks. You can tell the egg whites are done when they hold their shape when the beaters are lifted.
Add the milk and vanilla to the wet ingredients.
Stir the pumpkin puree, ricotta and pumpkin spice into the bowl with the rest of the wet ingredients.
Add the wet ingredients to the dry ingredients and mix.
Fold in the egg whites. Be careful not to over mix, or the pancakes will lose their light, fluffy texture.
Butter the griddle.
Pour batter onto griddle and cook about two minutes, or until bubbles begin to form on the top and then flip.
Cook for another two minutes, or until golden brown and transfer to an oven safe dish.
Keep warm in the oven until ready to serve.
Stack pancakes, adding a pat of butter in between each layer. Serve with vanilla or pumpkin spiced whip cream, and a drizzle of maple syrup, and toasted pecans if you want a bit of a crunch.
