In a large bowl, blend the pancake mix, water, red food coloring, cocoa powder, hot chocolate mix, vanilla extract, and vinegar. Stir until just combined.

Heat a skillet over medium heat and lightly grease it with oil or butter.

Pour generous spoonfuls of batter onto the skillet, leaving space between each pancake. Cook until bubbles appear and edges look set, about 2-3 minutes.

Gently flip each pancake with a spatula and continue cooking for another 2-3 minutes until fluffy and cooked through.

Once all the batter is used, stack pancakes on a plate and serve warm with your favorite toppings.
