As it is gluten-free (if gluten-free baking powder is used) and contains only ground almonds and polenta, the cake is very soft and falls apart easily, so needs to be handled with care.


  • 225 g butter
  • 225 g caster sugar
  • 190 g ground almonds
  • 3 medium eggs
  • 1 tsp of vanilla extract
  • Zest of two limes
  • Juice of one lime
  • 110 g polenta
  • A grinding of salt
  • 1 tsp baking powder (use gluten-free for a completely gluten-free cake)


  1. Grease an 8 inch silicone pan.
  2. Cream together the sugar and butter using an electric handmixer, until light and fluffy.
  3. Stir in the ground almonds and add the vanilla extract.
  4. Add the eggs one by one, mixing well between each one.
  5. Add the lime zest, lime juice, salt and polenta, and mix until fairly smooth.
  6. Pour the mixture into the silicone pan and place it in your slow cooker (I used a 5.7 litre one). Add some water beneath the pan if required by your slow cooker. Slow cooker lime polenta cake
  7. Replace the lid, tucking a tea towel beneath it to stop water dripping onto the cake.
  8. Cook on high for approx 2 hours or until a toothpick comes out clean.
  9. Allow to cool completely then carefully remove from the silicone pan.

Dust with icing sugar to serve, and add some mascarpone on the side for an extra treat.

I’m always in a constant look out for good gluten free cake recipe. This one sounds really good 😀


I’m yet to make a polenta cake but it looks incredible so I may have to give it a whirl. Lovely to discover your blog.x

I’ve never baked with polenta and this does look moist and light. Very intriguing on how you have baked it in a slow cooker- very clever indeed.

This sounds delicious. I bet it makes a very moist cake. The lime must add a fruity kick to it too! Yum! Thank you for linking up to #bakeoftheweek 🙂

I’m very fond of polenta cakes and the lime sounds just perfect for a summer day. The texture looks lovely.
