Ingredients
All ingredients are commonly available at most grocery stores.
¼ cup coconut oil – use cold-pressed, virgin coconut oil for best flavor.
3 tablespoons unsweetened cocoa powder – unsweetened cocoa keeps these bars sugar-free and intensely chocolatey.
2 tablespoons sugar-free maple syrup – choose a keto-friendly, monk fruit–based syrup for the best taste.
½ cup finely chopped walnuts – use unsalted walnuts and chop them finely for the ideal crunch.
2–3 drops pure vanilla extract – enhances the chocolate flavor.
1–2 dashes pink salt (or regular coarse salt) – balances sweetness with a touch of salt.
How to make them
Follow these four simple steps to make the best no-sugar keto bars.
(1) Line a standard loaf pan with parchment paper and set aside. Place the walnuts in a zip-top bag and crush them into small pieces using a rolling pin or a heavy pan.
(2) Melt the coconut oil in a large glass measuring cup or small saucepan. Whisk in the cocoa powder, sugar-free maple syrup, vanilla extract, and a dash of salt. Taste and adjust salt or syrup if needed. Stir the chopped walnuts into the chocolate mixture until evenly coated.
(3) Pour the mixture into the prepared loaf pan and spread it into an even layer using a spatula. Transfer the pan to the freezer and chill until the chocolate hardens, about 30 minutes.
(4) Remove from the freezer, lift the parchment out of the pan, slice into six bars, and serve. Store leftovers in the refrigerator to keep them crisp.
