Step 1: Prepare the Coffee

1. Brew a strong cup of coffee using your preferred method (drip, French press, or espresso). Allow the coffee to cool to room temperature before using it in the batter.

Step 2: Mix the Dry Ingredients

1. In a large mixing bowl, whisk together the flour, cocoa powder (if using), baking powder, baking soda, salt, and sugar. Ensure the dry ingredients are evenly combined to prevent clumps.

Step 3: Combine the Wet Ingredients

1. In a separate bowl, whisk together the cooled coffee, milk, egg, melted butter, and vanilla extract. Mix until smooth.

Step 4: Create the Batter

1. Gradually pour the wet ingredients into the dry ingredients, stirring gently with a whisk or spatula. Mix until just combined; it’s okay if the batter is slightly lumpy. Overmixing can result in dense pancakes.

Step 5: Preheat the Pan

1. Heat a non-stick skillet or griddle over medium heat. Add a small amount of butter and spread it evenly across the surface.

Step 6: Cook the Pancakes

1. Using a ladle or ¼-cup measuring cup, pour batter onto the skillet to form pancakes.
2. Cook for 2-3 minutes, or until bubbles form on the surface and the edges look set.
3. Flip the pancakes and cook for another 1-2 minutes, until golden brown and cooked through.
4. Repeat with the remaining batter, adding more butter to the skillet as needed.

Step 7: Serve and Enjoy

1. Stack the pancakes on a plate and top with your favorite toppings, such as whipped cream, maple syrup, or fresh berries. Serve immediately for the best texture and flavor.
