In a large mixing bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
In a separate pitcher or medium bowl, whisk together the buttermilk, eggs, melted butter, and vanilla extract. Stir in the red food coloring until the liquid reaches a deep, uniform crimson hue.
Pour the wet mixture into the dry ingredients. Use a rubber spatula to gently fold the batter until just combined. Stop as soon as the flour streaks disappear; a few small lumps are the secret to a fluffy pancake.
Heat a non-stick griddle over medium-low heat. Scoop 1/4 cup of batter per pancake. Wait until small bubbles appear on the surface and the edges look matte (about 2-3 minutes), then flip carefully and cook for another 1-2 minutes.
Whisk the glaze ingredients together until silky. Drizzle generously over warm stacks of red velvet pancakes and top with fresh berries for a professional, celebration-ready finish.
