Tips & Tricks

  • Use jimmies-style sprinkles (not nonpareils) to prevent color bleeding in the batter.
  • Don’t overmix the batter after adding the sprinkles to avoid dulling the colors.
  • Add a touch of almond extract for a subtle “bakery cake” flavor boost.
  • Let the cake cool fully before frosting to avoid melting the icing.
  • Decorate with extra sprinkles, piped frosting borders, or fresh fruit for added flair.
  • Store leftovers in an airtight container at room temp (up to 2 days) or refrigerate (up to 5).
  • Pair with cold milk or vanilla ice cream for a classic birthday-style combo.
  • Great for birthdays, baby showers, or casual weekend baking projects.
