  • In a separate bowl, whisk together the baking powder and baking soda. Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined. Be careful not to overmix.
  • Grease an oven-safe dish. Pour the batter into the prepared dish and bake at 325°F (160°C) for 35 minutes, or until a toothpick inserted into the center comes out clean.

  • Let the cake cool completely on a wire rack before frosting.
  • To make the frosting, microwave the heavy cream in 30-second intervals until hot. Pour the hot cream over the chopped white chocolate and let it sit for a few minutes. Whisk until smooth and glossy.
  • Divide the frosting into two portions. Leave one portion white. Divide the second portion in half again, tinting one half blue with gel food coloring.

  • Using a round cookie cutter or bowl, cut out a circle from the center of the cooled cake, creating a ring. Crumble the removed cake and set aside for another use (like cake pops!).

Recipe Notes

Good To Know

  • For extra visual flair, consider swirling a few drops of natural blue or purple food coloring into the batter before baking to mimic a "mermaid tail" effect—just drag a toothpick gently through the colors for a magical marbled look.
  • If you’d like a gluten-free version, substitute the regular flour with a 1:1 gluten-free baking blend; the moisture from the potatoes will help maintain a tender crumb even without gluten.
  • To intensify the date flavor, soak the dates in warm vanilla-infused milk for 10-15 minutes before chopping and adding them to the batter. This softens the dates and distributes their sweetness more evenly.

Expert Tips

  • Don't overmix the batter. Overmixing can develop the gluten in the flour and lead to a tougher cake. Mix until just combined.
  • For a richer flavor, use Medjool dates. They are softer and have a more caramel-like flavor compared to other date varieties.
  • If you don't have vanilla-infused milk, you can use regular milk and add a teaspoon of vanilla extract to the batter.

Storage Instructions

  • Store leftover cake in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days; the potato base helps the cake stay moist and fresh longer than typical cakes.
