Prepare the Coffee: Brew strong coffee and let it cool to warm or room temperature before using. This gives the pancakes a delicious coffee flavor without making the batter too hot.
Combine the Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, granulated sugar, and salt until everything is evenly distributed.
Mix the Wet Ingredients: In a separate bowl, whisk together the cooled brewed coffee, whole milk, egg, melted butter, and vanilla extract until smooth and well combined.
Make the Batter: Pour the wet ingredients into the bowl with the dry ingredients. Gently whisk until just combined. Do not overmix—the batter can have a few small lumps.
Let the Batter Rest: Allow the pancake batter to rest for a few minutes while you heat the skillet. This gives the flour time to hydrate and helps create a tender texture.
Heat the Skillet: Place a nonstick skillet or griddle over medium-low to medium heat. Lightly grease the surface with butter and allow it to heat evenly.
Cook the Pancakes: Pour portions of batter onto the hot skillet, leaving space between each pancake. Cook until bubbles appear on the surface and the edges look set. Carefully flip and cook the other side until golden brown and cooked through.
Serve Warm: Transfer the cooked pancakes to a serving plate and continue with the remaining batter. Serve warm with butter and maple syrup, or add whipped cream, berries, chocolate chips, bananas, or powdered sugar.
