Here’s a healthy version for a timeless cake from New Zealand – Sugar-Free Gluten-Free Louise Slice!
This recipe is very easy to make and even easier to enjoy with family and friends. Read on to find out how I made this timeless favourite deliciously sugar-free and low-carb.
Sugar-Free Gluten-Free Louise Slice – An Upgrade from an Old-time Classic
Louise cakes were rumoured to have been named after the daughter of Queen Victoria in the 1800s – Princess Louise of England. Others think it may have been named after Princess Louise's wedding cake.
Brought to New Zealand by British settlers, the recipe has been used throughout the centuries and is still being made in today’s kitchens – like mine!
It is typically made with a thin base layer of cake or biscuit crumbs topped with raspberry or plum jam, coconut meringue; then baked in a rectangular pan in the oven and cut into squares (hence why it’s called a “slice” rather than cake).
Families across New Zealand will have made their own family recipe for years, and all these different versions in the long span of time makes the cake slices all the more special.
You can enjoy this sugar-free gluten-free Louise slice for any occasion like anniversaries and parties – and you can even pack a square or two in your lunchboxes for school and work!
And of course, Louise slice is always to be found at a school bake sale - so bring a healthy sugar-free gluten-free Louise slice instead.
Share a Piece of History with Sugar-Free Louise Slice
Making a healthier version of a recipe that can be dated back to the 1800's shows that we don’t have to deprive ourselves of old-time favourites. This recipe has been long-engrained in New Zealand’s culinary history that it must be made available to all Kiwis living around the world who want to stay healthy, sugar-free and gluten free.
Making a sugar-free gluten-free Louise slice – or of any dish, for that matter – was far from the imaginations of its originators, but I bet that they would enjoy this healthier version nonetheless.
Like my other desserts such as no-bake lemon cheesecake and low-carb carrot cake, this healthy low-carb Louise Slice has no added sugar – without having to skimp on taste! Just because a cake is sugar-free doesn’t mean that it takes excitement and taste from it.
Going on a sugar-free diet benefits our bodies by lowering the risks of illness and disease; keeping the cravings at bay; making you feel more energetic and so much more.
Gluten-Free Louise Slice is a Pleasant Blast from the Past
As well as being sugar-free, this delicious Louise slice recipe is also gluten-free! Gluten is a type of protein that can be found in many grains and flours – which is a big no-no if you’re going on low-carb. Although gluten aids in maintaining the elasticity of the food it’s in and makes them chewier, it is worth giving it up entirely. Click here to read my article on Gluten free vs Grain Free.
Giving up on grains (and therefore gluten) greatly improves your digestive health and helps with healthy weight-loss and appetite control, for starters.
And because grains (and gluten) can be found in so many ultra-processed and unhealthy junk food, you’ll be sure to eventually eliminate these nasty products from your kitchens when living low-carb. And again, you can still enjoy food that is made gluten-free like my low-carb lemon cupcakes and my flourless berry sponge.

Gluten-Free Pastry Base
Sugar-Free Chia Jam
I would suggest making the sugar-free chia jam the night before, or at the beginning of this recipe, so it has time to swell and thicken.
Gluten-Free Pastry Base
- Mix all the ingredients together. Press into a square baking dish (20x20cm, 8x8inch) that has been lined with baking parchment.
- Bake at 180C/350F for 10 minutes, or until golden. Remove from the oven and allow to cool completely.
Sugar-Free Chia Jam
- Place all the ingredients in a bowl and mix well. Allow to set for 20-30 minutes. Chia seems to vary considerably so it may take a little longer to set, or may require an extra tablespoon of chia seeds.
- Gently spread the sugar-free chia jam over the cooled cooked base. Place in the fridge to set further.
Sugar-Free Coconut Topping
- Mix the coconut, sweetener and melted coconut oil together in a bowl. NOTE: Depending on how much moisture is in your shredded/desiccated coconut, you may require an extra tablespoon of coconut oil to ensure the coconut layer sets. To test, squeeze a little handful together. It just needs to hold together for a second, it will set hard in the fridge. But if it is completely crumbly, add extra coconut oil which is the binding agent.
- Spread gently the coconut layer on top of the chia jam layer. Place in the fridge to set completely.
- Store in the fridge for up to 4 days.
- May be frozen as individual squares in an airtight container which has been lined with baking paper.
