Transmogrified: Mother’s Day Lemon Cake with Kombucha Icing

Words, pictures, and recipe by Surya.

No matter the occasion, it’s hard to go wrong with cake. Mother’s Day? Obviously. Going on a picnic? Bring some cake. Got extra Kombucha? Make a cake!

Or make frosting for said cake, to be specific. For this version of Transmogrified, we bring you your new go-to sugar fix: Kombucha frosting.

This sweet, slightly tangy glaze only has four ingredients. You start with coconut oil and cocoa butter, melting them together to create a chocolatey-smelling “butter” (it’s vegan too, for all you dairy-free people out there). Add in some powdered sugar and the magic ingredient — Hibiscus Ginger Lime Kombucha — and that’s it!

The result is a frosting that’s got more depth than the typical butter-sugar mix. I paired it with a lemon poundcake (recipe here) to compliment the lime in the Kombucha, but I imagine the frosting would go well with almost anything.

We enjoyed it in the Aqua ViTea office on a sunny Friday afternoon — a perfect start to the weekend.

A tip: the frosting is a little more liquidy than other recipes, so refrigerate it for a few minutes before frosting if you want a more traditional consistency. Alternatively, if you refrigerate the cake after decorating the frosting will harden on the cake.



  1. Melt the cocoa butter and the coconut oil together in a double boiler or microwaved. Make sure it’s all mixed together, and then refrigerate until solid (this can be done in advance).
  2. When ready to make the frosting, thaw the “butter” at room temperature till it’s softened. Cream the butter with an electric mixer till it’s fluffy.
  3. Add in 1 cup of powdered sugar and 2 tablespoons of Kombucha at a time, mixing thoroughly. Add a final tablespoon of Kombucha at the end to get that extra tang.
  4. Decorate your cake! If you’re feeling fancy, add some chopped nuts or decorative petals on top.
