These red velvet cake waffles are a delicious and unique breakfast or brunch option. To make the waffles, start by mixing together flour, sugar, baking powder, and cocoa powder in a bowl. In a separate bowl, mix together buttermilk, eggs, red food coloring, and vanilla extract. Add the wet ingredients to the dry ingredients and mix until well combined. Pour the batter onto a hot waffle iron and cook until golden brown. Serve the waffles with cream cheese frosting and fresh berries.
