Are keto no bake lemon bars really low in carbs?

Yes, absolutely. Each bar contains only 2 to 3 grams of net carbs , depending on how you calculate the allulose (a sweetener that doesn’t impact blood sugar and is often subtracted like fiber). That makes these lemon bars a perfect fit for most ketogenic diets, even the stricter versions that cap net carbs around 20g per day. The use of almond flour , eggs , and allulose keeps the ingredient list clean and low-carb, with no grains, starches, or sugar to spike your glucose levels. Just be sure to check your lemon juice source if you're using bottled—some brands add sugar.

What sweeteners work best for keto no bake lemon bars?

The top choice is allulose . It blends smoothly, mimics real sugar’s taste and texture, and doesn’t leave a cooling or bitter aftertaste like some erythritol-based sweeteners. If you can’t find allulose, a monk fruit–erythritol blend is a second-best option, though you might notice a slight graininess in the filling or crust. Avoid pure stevia or liquid drops—they're too concentrated and can throw off the flavor balance. Quick Tip : Powdered sweeteners work best in the filling to keep the texture creamy.

Can I make keto lemon bars without using cream cheese?

Yes—and this recipe is proof! Unlike many keto dessert recipes, these keto no bake lemon bars skip cream cheese entirely. The filling uses eggs, lemon juice, zest, and sweetener , resulting in a soft, custard-like texture that holds up beautifully once chilled. If you prefer a dairy-free dessert or simply don’t like the heaviness of cream cheese, this version is lighter, brighter, and just as satisfying. You can also use coconut cream or mascarpone as optional swaps, but you honestly don’t need them.

How do you store keto no bake lemon bars for freshness?

These bars store exceptionally well. Here’s how: In the fridge : Keep them in an airtight container for up to 2 weeks . Use parchment between layers to prevent sticking. In the freezer : Wrap each bar individually in plastic wrap, then freeze in a sealed container or freezer bag. They'll stay fresh for up to 6 months . Thaw in the refrigerator overnight for the best texture. Make sure the bars are fully chilled before storing to help them hold their shape and avoid moisture buildup. Avoid leaving them at room temperature for long—since they’re no bake, they soften quickly.
