Low Carb No Bake Lemon Slice

You are going to love this recipe for a Low Carb No Bake Lemon Slice. The traditional recipe uses sweetened condensed milk as a binder in the recipe. I have recreated a low carb version of sweetened condensed milk and it is what helps to hold this recipe together. The flavors are just like the traditional recipe but without the carbs and added sugar. The fresh lemon juice and zest add a lovely lemony tang to the recipe. Feel free to alter the amount if you don’t want it so lemony.

Topping Options

I’ve given you the option of either icing/frosting the slice or you can simply sprinkle some coconut on top to serve. Either way, it tastes delicious. The end result is a simple to make but reasonably healthy snack. It is ideal for diabetics, celiacs or any one with a gluten intolerance. It’s also perfect for anyone following a low carb or sugar free diet.

Lemon Bliss Balls

This recipe is suitable for making into bliss balls as well. Just follow the recipe and shape into balls instead of pressing into a slice pan. Roll the balls in coconut and store in the fridge or freezer.Low Carb No Bake Lemon Slice

Storing Low Carb No Bake Lemon Slice

I love to slice this up and freeze it in portions so it’s easy to grab one if ever I feel like a healthy treat. You do need to store this slice in the fridge if you aren’t freezing it, as it will soften at room temperature.

No Bake Slices

If you enjoy making no bake slices, make sure you check out this recipe for a Sugar Free No Bake Chocolate Slice.  It’s a bit reminiscent of a Hedgehog slice, which is a slice made with sweet biscuits, butter, coconut and chocolate. It’s also really easy to make and is perfect for a healthy sugar free and low carb treat.

Recipe Notes

This recipe needs to be refrigerated. Because butter and coconut oil are used in it, it will soften at room temperature.
Feel free to omit the sunflower seeds or pistachio, and add macadamia or almonds in their place.
If you don't like your slice too lemony, adjust the amount of lemon juice to taste.

    This recipe tastes very similar to the condensed milk version I used to make! It is easy to make and tastes amazing. Even without the icing it tastes great.

    1. Thanks Natalie.
      I’m so glad you enjoyed the recipe. My intention was to recreate the condensed milk version, so I’m really happy with your feedback.
      This recipe is definitely a keeper.

    I love the taste and easy to make. Just wondering approximately how much lemon juice do you use? I used the whole lemon but I think it was too much

    1. Thanks Roz. Whenever lemon juice is used in recipes like this, it’s probably best to adjust recipes like this to suit your taste as some love lemon flavors while others like it to be more subtle. There can also be a difference with the taste of different lemons, and if you have a bitter batch it definitely can impact on the taste of recipes. I would say it is probably the latter that impacted on your recipe. Another way to combat the lemon flavor is to taste the mixture once it has been mixed together and if you find it too lemony, counterbalance the flavor by adding a small amount of additional powdered sweetener. Hope this helps. Kx

      1. Thanks for the reply. I was more referring to the amount of juice affecting the texture. I added more almond meal as it seemed way too soft and once set in the fridge is still quite soft.
        Oh wait you know what, I just realised I didn’t add the coconut flour. My bad. I’ll just have to make it again!

            Feel free to delete my 4 star rating cos clearly I’m an idiot lol.
            We’ve nearly eaten the whole thing though so still tastes great.
            But I will definitely be making it again. We have 2 lemon trees and my hubby loves lemon slice.
