I add the sugars, flour, cinnamon, vanilla and water into a small saucepan and bring it to a gentle boil, stirring the whole time so nothing sticks or burns. Once it starts bubbling, I slowly mix in black food coloring until the syrup turns fully black. I let it simmer for a couple more minutes so it thickens up properly before taking it off the heat.
In a large bowl, I whisk together the pancake mix, milk, eggs, pumpkin puree, sugar, cinnamon and nutmeg until it is smooth. Then I add my food coloring a little at a time until I get that bright pumpkin-orange shade I am going for. I try not to overmix, since a few small lumps are totally fine and actually keep the pancakes tender.
I heat my griddle or skillet over medium heat and lightly grease it before pouring the batter in quarter-cup portions. Each pancake takes about 2 to 3 minutes per side, and I know it is time to flip once I see little bubbles forming on top. I keep the heat steady so they cook through without burning on the outside.
Once all the pancakes are done, I stack them up on a plate while they are still warm. Then comes my favorite part, pouring that spooky black syrup generously over the top. I serve them right away so everyone gets to enjoy the pancakes while they are fluffy and hot.
