Equipment

Ingredients

Chocolate Nougat

Caramel

Coating

I used a silicone bar mould that is now discontinued. A silicone large icecube tray would be perfect for 32 x 4cm mars bites.

    Instructions

    Nougat

    • Place the syrup and chocolate into a large heat-safe bowl and microwave for 1 minute. Stir to combine and melt chocolate.
    • Combine chocolate mix with WPI and MCT oil and mix until combined. With a gloved hand massage mix until it is no longer grainy.
    • Spoon or break off pieces and push into moulds (will make 32 x 4cm moulds). Set aside.

    Caramel

    • Place all caramel ingredients into a large heat-safe bowl. Heat on high for 3 minutes. Carefully remove from microwave stir mixture and return to microwave. Continue to heat at 1-2 minute intervals until mixture looks very bubbly when you take out and when stir becomes thicker and more viscose. At this point, you will definitely smell a caramel scent.
    • Carefully spoon the hot caramel into your moulds. Refrigerate until set.
    • Melt chocolate and thinly coat each mars bar.

    Notes

    1. Any keto syrup sweetener used must have the main ingredients as a syrup (non-GMO corn or tapioca syrup). Allulose syrup is also a good alternative. There are some low carb syrups on the market that have the first ingredient listed under ingredients as water. Those products are not suited to this recipe.
    2. Chocolate, for the Milk Chocolate you can use any of the following zero sugar varieties, Vitawerx, or Well Naturally. Each of these brands offers a low carbohydrate, no sugar at all, and low-calorie option.
    3. The bars are best stored in an airtight container in a cool dry place. If refrigerated you will find that they are a lot harder, just like the real thing if stored in a fridge or freezer.
    4. All keto sweets should be a sometime food. This recipe could easily be made into smaller portions or drops similar to a Rolo.
    5. Please use caution when making the caramel. The instructions for the microwave are open in time as many microwaves have different wattage. In mine at 750W I find the caramel takes around 8-10 minutes. As it starts to get a little thicker you will notice if you check your spoon after 30 seconds you can gauge what "ball" or setting stage your caramel is at. For your convenience, I have included a video to show you the look and feel the caramel has when it is ready to pour.
