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

It’s also really easy to make and is perfect for a healthy sugar free and low carb treat.
