In a mixing bowl or stand mixer, whisk the butter until it becomes smooth.
Add the chopped parsley, minced garlic, salt, black pepper, and red pepper flakes to the butter mixture and blend well.
Take a toothpick, skewer, or large needle and insert it into the center of the bottom of a paper cup.
Feed the 4" wick through the hole created in the cup.
Using a small rubber spatula or spreader, press the butter mixture into the paper cup around the wick until it is full.
Gently tug on both the top and bottom of the wick to ensure it is centered.
Place the filled cups in the refrigerator for about 30 minutes or until the butter is solid.
Once solid, gently tear away the paper cup to remove the butter candle.
To serve, bake or warm some bread, then cut a round loaf into quarters or eighths and insert the candle before lighting it.
As the candle burns, the melted butter will seep into the loaf.
