In a large bowl, whisk together 2 cups of flour, 2.5 tablespoons of sugar, 1 tablespoon of baking powder, 2 teaspoons pumpkin spice (or cinnamon), 1.5 teaspoons of baking soda, and 1.5 teaspoons of salt. Weigh the final dry mixture using a food scale to get a final weight on it, then divide the dry mixture in half.
In a separate mixing bowl or container, whisk together 1.5 cups of milk, 3 tablespoons of vinegar, 2 eggs, 3 tablespoons of melted butter, and 1 tablespoon of vanilla extract. Weigh the wet ingredients, and separate half of the batter into a separate container once again.
Add ½ teaspoon of orange gel food coloring to one of the wet containers until a vibrant orange color is achieved. In the other wet container, add ½ teaspoon of black food coloring to make a black base of the batter. Combine each of the bowls of dry ingredients with the wet ingredients to make one orange batter and one black batter.
Use a rubber spatula to fold the ingredients together very gently. It's okay if there are lumps in the batter! This will help us achieve a really light and airy pancake. Don't overmix! Allow the batter to rest for just a few minutes before making the pancakes.
Rub or brush a hot griddle or skillet with a small amount of butter to lightly grease the pan. Working in batches, add about ¼ cup of batter for each pancake. Don't overcrowd the skillet or griddle, give yourself room to flip the pancakes.
Cook for a few minutes until golden on the bottom and bubbles start to appear on the top, then flip over and cook an additional minute or until golden brown. Add more butter with each new batch of pancakes.
Serve hot with butter and a drizzle of maple syrup or our "bloody" raspberry syrup. You can also add food coloring to maple syrup if you prefer.
Store leftovers in an airtight container in the fridge for up to 4 days. For best results, don't put butter or syrup on the pancakes before storing or the will become soggy. Reheat in the microwave or on the stovetop.
