What You’ll Need
- 2 cups Almond Flour
- 1/4 cup Granulated Sweetener
- 2 tablespoons Melted Butter (or melted coconut oil)
- 1 large Egg
- 1/4 teaspoon Salt
- 1 teaspoon Vanilla Extract
- 4 large Eggs
- 1/2 cup Lemon Juice
- 1/4 cup Melted Butter
- 1 tablespoon Lemon Zest
- 1/4 cup Almond Flour
- 1/3 cup Granulated Sweetener
- 3 tablespoons Powdered Erythritol (like powdered erythritol)
- 1 tablespoon Lemon Zest
Feel free to substitute ingredients based on what you have at hand. For instance, you can use coconut oil instead of butter for a dairy-free option.
Directions to Follow
Preheat the oven to 350°F (180°C). Line a 9-inch square pan with parchment paper, leaving some paper hanging over the sides. Lightly grease the paper with butter or coconut oil and set aside.
Prepare the shortbread crust: In a mixing bowl, combine almond flour, salt, granulated sweetener, beaten egg, vanilla extract, and melted butter. The mixture should be crumbly, yet hold together when pressed. If it’s too dry, add an extra tablespoon of melted butter.
Press the crumbly shortbread mixture into the prepared pan evenly and firmly. Prick the crust with a fork.
Pre-bake the crust for 15 minutes until golden brown and crispy around the edges.
While the crust is baking, prepare the lemon filling: In a mixing bowl, whisk together the eggs, lemon juice, melted butter, granulated sweetener, and lemon zest. Finally, incorporate the almond flour for a smooth consistency.
As soon as the crust comes out of the oven, pour the lemon filling on top.
Return the pan to the oven for another 15-18 minutes, or until the filling is set on top but still soft and jiggly in the center. Keep a close eye to avoid overbaking, which can dry out the filling.
Allow the bars to cool in the pan for 1 hour before transferring them to the fridge to chill for 3 hours or overnight for easier slicing.
Serve chilled, optionally dusted with powdered erythritol and extra lemon zest for an added burst of flavor.
How to Serve Keto Lemon Bars
These Keto Lemon Bars are best served chilled, making them a refreshing option for warm weather. You can plate them elegantly with a dusting of powdered erythritol and a sprinkle of lemon zest on top. For added flair, consider pairing them with whipped cream (sugar-free, of course!) or some fresh berries for a delightful contrast. They make an excellent compliment to a cup of afternoon tea or coffee, brightening up any dull moment.
Storage and Reheating Tips
To keep your Keto Lemon Bars fresh, store them in an airtight container in the refrigerator for up to a week. If you want to enjoy them later, you can also freeze the bars. Simply wrap them tightly in plastic wrap and then in foil before placing them in a freezer-safe container. They can be frozen for up to two months. To defrost, just take them out of the freezer and let them sit at room temperature. For best results, consume the bars within a month for optimal flavor and texture.
Helpful Cooking Tips
- Ensure that you only beat the filling until combined; over-mixing can lead to a fluffy texture instead of a creamy, smooth filling.
- Add more lemon zest for an extra punch of citrus flavor.
- If you’re looking to make these bars vegan, try replacing the eggs with a flaxseed meal substitute or a commercial egg replacer.
Creative Twists
Feeling adventurous? Try incorporating additional flavors into your Keto Lemon Bars! You can add a hint of lavender for a floral note, or mix in some fresh herbs like basil or mint to provide an unexpected twist. If you enjoy berries, try a layer of raspberries or blueberries on top of the filling before baking for a fruity surprise!
