Every keto diet needs a sweet thing you can trust, and this is ours. It is soft, rich chocolate fudge made with tahini instead of sugar and cream, it takes ten minutes to mix, and it needs no oven. One piece is enough to end a meal or fix an afternoon craving, without touching your carbs for the day.
One piece gives 128 kcal, 5 g of protein, 11.4 g of fat and 2.2 g of net carbs (4.1 g of total carbs minus 1.9 g of fibre). The tin makes 12 pieces, and the numbers come from the DietSync app, where every ingredient is weighed in grams.
Tahini is the sesame paste every Greek and Cypriot kitchen already has, the base of halva and of tahini spreads. It is rich and creamy, low in net carbs and mostly healthy fat, which makes it a perfect keto base for sweets. Mixed with cocoa it tastes a little like halva and a little like a chocolate truffle. And since sesame is a seed, not a nut, the fudge is nut-free.
Most of the calories in the tin come from the 150 g of tahini, about 890 kcal, and the 50 g of coconut oil, about 430 kcal. That fat is what makes it feel like real fudge. The 40 g of chocolate whey adds about 30 g of protein to the tin and the tahini about 25 g, which is why each piece has 5 g. The net carbs come mainly from the tahini and the cocoa, and the fibre in both keeps them at 2.2 g a piece.

The chocolate whey does three jobs. It adds protein, so a sweet snack also counts towards your daily target. It thickens the mix, so the fudge sets firm without condensed milk or sugar syrup. And it brings extra chocolate flavour and a little sweetness, which means you need less sweetener. Without it, the fudge would be softer, oilier and closer to a tahini spread.
Start by stirring the tahini well in its jar, because the oil separates on top. Then melt the coconut oil gently, just until it turns liquid, and whisk it into the tahini until smooth. If the oil is too hot, the whey can turn grainy when it goes in. Add the cocoa, whey, sweetener and salt and mix until the mixture is glossy and thick, like a soft dough. If it's too stiff to spread, add a teaspoon of melted coconut oil; if it's too runny, a little more cocoa.
This recipe uses a no-calorie liquid sweetener, which mixes in evenly without any grittiness. Stevia or sucralose drops both work; start with less and taste, since brands differ in strength. Avoid honey, maple syrup and agave: they are sugar, and even a spoonful would multiply the carbs of every piece. Granulated sweeteners work too, but they can leave the fudge slightly gritty.
Coconut oil melts at about 24°C, so the fudge softens quickly in a warm kitchen or a bag. Store it in an airtight box in the fridge, where it keeps for a week, or in the freezer for up to 2 months. Straight from the freezer it is firm and chewy; after 5 minutes on the counter it turns soft and creamy. Both are good, so try it both ways.
The base takes flavours well. Sprinkle a few flakes of sea salt on top before it sets, stir in a pinch of cinnamon or a little grated orange zest, or add a drop of vanilla or a spoon of instant coffee for a mocha fudge. All of these add almost nothing to the numbers. Chopped pistachios or almonds on top look great, but they add carbs and the fudge is no longer nut-free, so log them.
Fudge is easy to overeat, keto or not. At 128 kcal a piece, three pieces add up to almost 400 kcal, more than a protein smoothie. Cut the whole tin into 12 as soon as it sets, and log the piece before you eat it. If you want smaller treats, cut it into 16 pieces of about 96 kcal each.
At 2.2 g of net carbs, one piece fits easily into a strict 25 g keto day. Have it after one of the dinners in our 7-day keto meal plan, or as a snack with coffee. For a bigger sweet fix, try the chocolate avocado protein smoothie or the keto pistachio protein bars.
The fudge is in the DietSync app, in the Keto Snacks book. Log a piece in one tap and the app keeps count of your net carbs, protein and fat for the day.
Tahini separates in the jar. Stir it well before weighing, or the fudge comes out oily on top and dry underneath.
Melt the coconut oil just until liquid. Too hot, and the whey can turn grainy when it goes in.
Dip the knife in hot water and wipe it dry between cuts for neat squares.
2.2 g: 4.1 g of total carbs minus 1.9 g of fibre. Most of them come from the tahini and the cocoa.
Yes. Tahini is made from sesame seeds, not nuts, so this fudge suits people who avoid nuts. Sesame is a common allergen itself, though, so check before you share it.
A chocolate whey. We use FuelSync Chocolate. Any chocolate whey with few carbs works; vanilla works too, with a slightly milder chocolate taste.
Coconut oil melts at about 24°C, so the fudge softens in a warm room. Keep it in the fridge and take out only the piece you are about to eat.
