A dessert under 5g net carbs per serving keeps your daily total under 20g and keeps you in ketosis. Above 5g, a dessert becomes a "weekly treat" rather than a regular option. Every recipe below clocks under that line, most under 4g.
The trick isn't avoiding sugar (everyone knows that). It's the base ingredients. Almond flour adds up faster than you'd think (about 3g per quarter cup), so portion control matters even when the ingredient list looks clean.
Sweeteners that won't kick you out of ketosis
Allulose: 0 glycemic index, tastes closest to sugar, bakes well, no aftertaste
Erythritol: 0 GI, can crystallize when cold (cooling effect), blends well with monk fruit
Monk fruit: 0 GI, very sweet (use sparingly), often blended with erythritol
Stevia: 0 GI, intensely sweet, can have a bitter aftertaste in baked goods, best in liquids
Sweeteners to avoid (even with a "keto" label)
Maltitol: GI of 36, will spike blood sugar and kick you out of ketosis. Hides in many "sugar-free" chocolates and candies.
Sorbitol, mannitol: similar issues, plus digestive distress in many people
Agave or honey: hidden in some "keto" granola bars and protein bars. Always read the ingredient list, not just the front of the package.
Coconut sugar / date sugar: marketed as "natural" but functionally identical to table sugar for ketosis

Storage tips
Most cream-based desserts last 3 to 5 days in the fridge in a sealed container.
Fat bombs and chocolate bark freeze beautifully for up to 2 months.
Custards and panna cottas are best within 48 hours.
Cookies and mug cakes are best fresh; almond flour bakes don't reheat well.
3 common dessert mistakes on keto
Daily dessert habit stalls weight loss. Even at 3g net carbs, daily 200 to 400 calorie desserts add up. Treat them as 2 to 3 times per week.
Hidden almond flour carbs. A quarter cup of almond flour is 3g net carbs. A serving of mug brownie that uses half a cup is 6g, before the chocolate. Measure, don't eyeball.
Not measuring sweeteners. Too little = bland; too much = artificial-sweetener aftertaste that ruins the dessert. Start with the recipe's specified amount, then adjust to your tolerance.
