Note: If you’re concerned about it tasting too ‘sugar-free’, then simply substitute half of the Splenda with real powdered sugar.

  • Powdered Sugar Topping – This trick works as a great way to cover up any flaws of your cake and allows the full-flavor of your cake to come through. Try using a stencil to create a beautiful design that will make your guests forget that you opted to go low calorie and go without any frosting. A light powdering may just be all that you need.
  • Low Calorie Fruit Glaze – If you’re really trying to cut calories, opt for a fruit glaze such as pureed pineapple mixed with a bit of Splenda. It won’t harden,  but goes great on top of white cakes. You can also use sugar-free jams; they make phenomenal low calorie glazes.

  • Hi Sarah –

    So sorry I am just seeing this now! I see you are from the UK…cornflour is equivalent to what we call ‘corn starch’ in the US.

    Hi, for the low calorie powered sugar icing, I was just wondering whether corn starch is the same as cornflour? As I can’t seem to find cornstarch in my local supermarket? Thanks

  • Anna – eating low calorie almost always requires omitting unhealthy fats such as butter or full fat sour cream. The frostings still taste great and are simply a different kind than higher calorie and unhealthy versions. If you can find a low calorie frosting recipe with butter, then please do share with us! 🙂

  • I just made the low calorie cream cheese frosting again this evening but since I only had about 2 oz of cream cheese, I used that 2 oz with about 2 oz of cool whip and it still tasted pretty “cream cheesey”. So, you can cut back on FF cream cheese even more, if you’d like!

    I LOVE the low calorie peanut butter frosting with cool whip and low-fat peanut butter. It’s a light, yet rich tasting frosting. Really good. It goes really good on top of ‘No Pudge’ brownies (you can buy the mix at the grocery store). This is my new favorite dessert
