Avocado Lime Cake – it is totally a thing!

avocado-lime-cake-1-webAvocado Lime Cake, sounds weird, tastes delicious.  It really does.  I know, as Kermit the Frog said,  “it’s not easy being green” but this is well worth broadening your views on cake colours for.  I will admit that my first attempt at the icing was a bit too green and didn’t look particularly appetising on day 2 when the avocado “tinged” a bit but it still tasted great  (the tiny food critics didn’t agree even though they loved it the day before). This photo was of my second and much better attempt which everyone scoffed down at a ladies “high tea”.  Want to give it a go?

The original recipe can be found here.  I have adapted the recipe to make it gluten free (just changed the flour), refined sugar free (although I did use some icing sugar in the icing which is optional, the cake itself is refined sugar free) and Thermomixed it up.  See below plus some step by step pics in case you were wondering.

Avocado Lime Cake


  • 1 lime
  • 85 g butter, softened
  • 200 g Rice Malt Syrup (or 200 g sugar)
  • 1 large avocado
  • 2 eggs
  • 1 tsp vanilla extract
  • pinch sea salt
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 200 g Sorghum flour (or any GF Flour mix or plain flour)
  • 100 g butter milk (if you don't have any butter milk just squeeze a bit of lemon into normal milk and let it sit for 5 minutes and then you will have buttermilk!)
  • For the Icing (optional)
  • ½ very ripe avocado, pitted, peeled
  • Zest of 1 lime
  • Juice of ½ lime
  • 35g unsalted butter
  • 100g icing sugar


  1. Preheat the oven to 180 C and line a large loaf tin with baking paper
  2. Peel the lime and then grate it in the TM bowl 15 seconds / speed 7. Set aside
  3. Cream the butter and Rice Malt Syrup speed 5 / 40 seconds
  4. Add the lime juice, zest and peeled and stoned avocado mix together Speed 4 / 5 seconds
  5. Add the eggs and vanilla extract and beat Speed 4 / 5 seconds, scrape sides
  6. Add a pinch of salt, baking soda, baking powder and flour and mix Speed 4 / reverse / 8 seconds, scrape sides
  7. Add buttermilk Speed 2 / reverse / 10 seconds
  8. Pour into prepared tin and bake in the oven for 55 minutes to an hour or until an inserted skewer comes out clean
  9. Leave to cool in the tin for about 15 minutes and turn out onto a wire cooling rack to cool completely
  10. For the Icing
  11. zest the lime peel 20 seconds / speed 7
  12. Add all the other ingredients and combine speed 4 / 20 seconds
  13. You may want to leave the avocado until the end and add slowly just to test what colour it will be
  14. Once the cake has cooled completely ice it and sprinkle some extra lime zest on the top and enjoy!

OK so this is what it looks like when you have creamed the butter & RM Syrup and added the lime and avocadoavocado-lime-cake-step-1-web

Next photo – this was when everything but the buttermilk had been added (not quite so green now)


This is when it’s ready to go in the oven.

avocado-lime-cake-step-3-webI actually used a mid sized tin for the main “loaf” and then 3 muffin cases as I needed to give the girls and a friend something for afternoon tea but wanted to use the big cake the next day.  I cooked the cupcakes first for 20 minutes and then the bigger cake for 55.  I didn’t do the icing until just before I needed it (second time round!).

Do you want to see the mistake green icing?


A bit too green to be seen (but didn’t bother GT!).

This one below was the one I served up for the “high tea” and got positive feedback!


How does avocado cake sound to you?  Will you try it?  It really is yummy!
