In a large mixing bowl, combine 3 cups of all-purpose flour, 1 cup of sugar, 2 tablespoons of baking powder, and 1 teaspoon of salt.

In a separate bowl, whisk together 1 cup of milk, 2 large eggs, and 4 tablespoons of melted butter until smooth.

Slowly pour the wet mixture into the dry ingredients, stirring gently with your spatula.

Divide the dough in half. Add a few drops of black food coloring to one half and red to the other.

Cover the colored doughs with a clean kitchen towel and let them rise for about 2 hours.

Preheat your oven to 350°F (175°C) and grease a standard loaf pan.

Transfer the colored dough into the prepared pan, swirling the red and black dough together gently.

Bake for approximately 30 minutes, until golden brown.

Once baked, let it cool in the pan for about 10 minutes before transferring to a wire rack.
