1st Birthday Sugar-Free Smash Cake

When my cousin Becki’s little girl Mia turned one, I was given the huge honour of baking her 1st birthday cake! My cousin wanted a cute cake for her party, but wanted Mia to be able to enjoy it, so wanted a recipe that wasn’t full of sugar. I set about researching online and came across a sugar free banana and sultana cake recipe that seemed to be perfect. The recipe didn’t include any icing though, so I ended up going with a traditional butter cream, sugar and all! This is the rather cute outcome my experimental  baking…


Fast forward 4 years to her little boy Alfie’s 1st birthday. I text Becki a few days before the party asking how the plans were going, and she said great, apart from not having a cake! I hadn’t previously offered as Becki has starting baking more since Mia was little and I didn’t want to tread on her toes. But poor Alfie couldn’t be cakeless at his own party! Becki felt bad and said she hadn’t been hinting, but I really do feel like its a special honour to bake someone’s first ever birthday cake! I was in much more of a rush this time, so wasn’t able to come up with a design and a theme, but I actually like how this simple cake turned out. It wasn’t technically a smash cake, as no smashing occurred, but Alfie and his baby friends loved it, and actually so did the adults that tried it too!


After some research and tweaking of lots of different recipes and ideas, I ended up with this recipe, including sugar free icing!


For the cake

  • 4 bananas, mashed but still lumpy
  • 2 beaten eggs
  • 4 big handfuls of sultanas
  • 75g of butter
  • 115g of self-raising flour

For the icing

  • Tub of cream cheese
  • Handful of blueberries
  • Agarve nectar to taste, I used 1tbsp
  • Natural food colouring (optional – the blended blueberries give a lovely pale pink colour!)


  1. Mix together the mashed bananas and eggs
  2. Add the rest of the cake ingredients and mix well
  3. Pour into a greased and lined cake tin
  4. Bake at 180c for about 40 minutes, until a skewer inserted into the middle comes out clean. Leave to cool
  5. For the icing, simply blend together all of the ingredients, it became quite runny so I left it in the fridge for about half an hour before pouring over the cake

  1. what a cute little pink cake, but I have to say the blue one looks amazing too and sounds really yummy, so glad you have shared the recipe #sharingthebloglove

  2. A sugar free first birthday cake is a great idea! I remember the one we made was a full on chocolate cake so I was quite funny about my son having any – of course he did anyway, and loved it – but this sounds like a perfect compromise. I love the pretty blue icing! Thanks so much for joining us at #SharingtheBlogLove

  3. Oooh I love a good cake recipe, and what a fab idea to make it sugar-free. I’m afraid this never even crossed my mind, even though I’m usually really careful about what my little ones eat. I really like the hedgehog one – very effective #SharingTheBlogLove

  4. Both my daughters 1st birthday cakes were either sponge or chocolate cake and to be honest they weren’t fans of them. Of course that has now changed and they love cake! I never knew you could make a sugar-free one, I should have researched better. I love a nice simple design, they look the best. Thank you for sharing with us at #SharingtheBlogLove x

  5. you’ve not only created some amazing cakes, but some beautiful memories for that family to treasure forever. We did a cake smash for our daughter’s first birthday and it was such a wonderful day. Seeing them taste cake and icing for the first time, is the best thing ever! You’re very talented! #sharingthebloglove
