Any type of dates will work in this recipe, however, Medjool dates are typically the sweetest and most flavorful. If you’re using a different type of date, you may need to add a bit more sugar to the batter to balance out the sweetness.   If your dates are too dry or hard, soak them in hot water for 5-10 minutes before using. This will help soften them up and bring out their natural sweetness.
