Keto-friendly when sweetened with erythritol/stevia/monk fruit. Erythritol is a non-impact sweetener, so keto net carbs (~2.5g per 100g, ≈1g per 40g bar) come out far below the total carbs on the label. Just avoid maltitol-heavy bars.

WHY IT'S KETO-FRIENDLY
- High fat, low sugar when sweetened with non-impact polyols (erythritol) or stevia/monk fruit—erythritol isn't counted toward net carbs, so net stays low (~2.5g/100g, ≈1g per 40g bar)
HEALTH BENEFITS
- Cocoa provides polyphenols and flavanols; lower glycemic impact than regular chocolate

Bulletproof Original Milk-Style Chocolate Bars, 4 Count, Sugar-Free Keto Chocolate with MCT Oil
Healthline's keto candy roundup names Bulletproof's Original Milk-Style Chocolate Bar the "best for milk chocolate lovers" pick, delivering just 2g net carbs per 30g serving because it's sweetened with erythritol/stevia instead of sugar and is fortified with brain-octane MCT oil rather than the fillers found in typical sugar-free chocolate.

ChocZero Milk Chocolate Almond Bark, No Added Sugar, No Sugar Alcohols (4 Count, 3.2oz Boxes)
For keto shoppers who react badly to erythritol or maltitol, ChocZero skips sugar alcohols entirely and sweetens with monk fruit plus soluble corn fiber instead. Low Carb LAB and KETO-MOJO both rate it among the best-tasting sugar-free chocolates they've tried, with one reviewer calling it 'simply the best sugar-free chocolate I've ever had.' The milk chocolate almond bark delivers about 1g net carb per serving and 8g fiber per piece, positioning it as the premium, gut-friendlier alternative to erythritol-sweetened bars like the existing pick.
