In a large mixing bowl, sift together flour, cocoa powder, sugar, baking powder, and salt. Create a well in the center and pour in milk, egg, and melted butter. Mix gently until just combined, then add red food coloring to achieve desired hue.

Preheat a non-stick griddle or skillet over medium heat. Grease lightly. Pour ¼ cup of batter for each pancake. Cook for about 2 minutes or until edges look set and bubbles form, then flip and cook for an additional minute.

In a medium bowl, combine powdered sugar and milk. Whisk until smooth and creamy, adjusting consistency with more milk if necessary.

Stack the warm pancakes on a plate and drizzle the glaze generously over the top. Garnish with fresh berries or whipped cream and serve immediately.
