What to serve it with

This cake can be enjoyed on its own, but for an exquisite experience, consider serving it with a dollop of whipped cream or a scoop of vanilla ice cream. Fresh lemon slices can add a bright touch for presentation and enhance the citrus notes. Pair it with a refreshing herbal tea or a light sparkling beverage for a delightful afternoon snack or dessert.

How to store and freeze

To keep your cake fresh, store any leftovers in an airtight container in the refrigerator for up to 5 days. If you want to enjoy this treat later, you can freeze it for up to two months. Just make sure to wrap it tightly in plastic wrap and then in aluminum foil. When ready to eat, thaw it in the refrigerator overnight and reheat in the oven at a low temperature if desired. Remember to follow the 2-hour rule for any perishable item left at room temperature.

Tips for best results

  • Make sure to squeeze excess moisture from the grated zucchini to avoid a soggy cake.
  • Feel free to adjust sweetness by modifying the amount of honey based on your taste preference.
  • For added texture, try mixing in chopped nuts or coconut flakes.
  • Be gentle when folding in the blueberries to prevent them from breaking apart.
  • Allow the cake to cool completely before frosting to ensure the buttercream doesn’t melt.

Creative twists

  • Swap out the blueberries for raspberries or strawberries for a different fruity flavor.
  • Add a pinch of cinnamon or nutmeg for a warm, spiced twist.
  • Use a gluten-free flour blend if you’re looking for a gluten-free option.
  • Experiment with different citrus by adding orange zest or juice into the batter.
  • Top the cake with a cream cheese frosting instead of buttercream for a tart alternative.
