Enjoy these tasty & simple keto lemon bars when you’re looking for a sweet treat that’s easy to make & low in carbs.
If you love the bright, refreshing flavor of lemon, these Keto Lemon Bars are a delicious treat to keep in your recipe rotation! They’re tangy, lightly sweet, and have a buttery almond flour crust that pairs beautifully with the creamy lemon filling.
With just 3.2 grams of net carbs per serving, these lemon bars can be a nice option when you’re looking for a lower-carb dessert or snack without giving up that classic sweet-tart flavor.
The recipe comes together with simple ingredients like fresh lemons, eggs, almond flour, coconut flour, butter, and monk fruit sweetener or erythritol. Fresh lemon zest and juice provide plenty of natural citrus flavor, so you don’t need a long list of ingredients.
A Bright, Lower-Carb Treat
Lemon is one of those flavors that can make a dessert feel especially fresh and satisfying. The combination of tart lemon filling and a rich, slightly nutty almond flour crust makes these bars a great choice for an afternoon treat, dessert, or something special to enjoy with a cup of tea!
And because they’re made with almond and coconut flour rather than traditional wheat flour, they’re naturally grain-free as well.
Keto Lemon Bars Recipe
Prep Time: 20 minutes
Cook Time: 30 minutes
Serves: 9
Ingredients:
For the Lemon Filling:
- 3 large eggs
- 2 lemons, zested and squeezed to yield ¼ cup lemon juice
- ¾ cup + 1 tablespoon monk fruit sweetener or erythritol, divided
- ¼ cup coconut flour
For the Crust:
- 8 tablespoons unsalted butter, melted
- 1 cup + 5 tablespoons almond flour
Directions:
- Add the eggs, lemon juice, 1 tablespoon lemon zest, ¾ cup monk fruit sweetener, and coconut flour to a blender. Blend until smooth and creamy. Place the mixture in the refrigerator for 15–20 minutes, or until slightly thickened.
- When you’re ready to bake, preheat the oven to 350°F. Line an 8×8-inch square baking pan with parchment paper.
- In a medium mixing bowl, combine the melted butter, almond flour, and remaining 1 tablespoon of monk fruit sweetener. Mix until a smooth dough forms.
- Press the almond flour mixture evenly into the prepared baking pan. Par-bake the crust for 7 minutes.
- Remove the crust from the oven and set it aside to cool slightly while the lemon filling continues to thicken in the refrigerator.
- Pour the lemon filling over the crust. Return the pan to the oven and bake for 18–20 minutes, or until the center is set.
- Remove the pan from the oven and place it on a cooling rack. Allow the lemon bars to cool completely before slicing and serving.
A Few Simple Tips
Use fresh lemons. Freshly squeezed lemon juice and freshly grated zest give these bars their best flavor. Since the lemon is the star of the recipe, bottled juice won’t quite provide the same brightness.
Let them cool completely. It may be tempting to cut into the bars while they’re still warm, but allowing them to cool fully helps the filling firm up and makes cleaner slices.
Chill for an extra-fresh treat. For an especially refreshing dessert, refrigerate the finished bars before serving. They’re wonderful cold and can be a great make-ahead option for potlucks or dinner parties!
Choose your sweetener thoughtfully. Monk fruit sweeteners and erythritol can vary in sweetness and texture depending on the brand, so results may differ slightly.
A Simple Lemon Dessert to Enjoy
