If you love lemony, tangy desserts then this recipe is for you. Not only is this one of the best tasting keto desserts you can make but it’s so easy to prepare too. 

The creamy lemon filling and buttery shortcrust melt in your mouth and will leave you wondering how on earth something that tastes so rich and indulgent could possibly be low-carb! 

How to make keto lemon bars

Step 1: Measure out all the ingredients and preheat your oven to 325 ° F (160 ° C).

Step 2: Grease a 9”x 9” (23cm x 23cm) baking pan and line it with a strip of parchment paper (you don’t need to use the parchment strip if your pan has a removable base.)

Step 3: Add the unsalted butter and pulse to combine, until it reaches a sandy consistency.

Step 4: Add the egg and vanilla extract to the food processor. Pulse to combine until the dough is well mixed and forms pea-sized pieces. There should be no dry areas in the dough. 

Step 5: Press the shortbread dough firmly into the prepared pan using the back of a glass or your hands.

Step 6: Bake for 12-15 minutes, until the outer edges of the crust have just begun to brown. It should not be fully cooked at this stage as it will cook further once the filling has been added. Remove and leave the oven on.

Step 7: Mix together all the ingredients for the filling until completely smooth and pour over the baked crust.

Step 8: Bake for 30 – 35 min. The lemon bars are done cooking once the filling stops moving if shaken slightly. Remove from the oven and allow the lemon bars to cool completely for at least an hour. Cut and serve when desired.

Tips for making the perfect lemon bars

Before you start preparing the shortcrust base of the lemon bars, remove the cream cheese from the refrigerator and let it sit out for at least 30 minutes before using it the filling. This makes sure that the cream cheese is easy to beat and won’t leave any lumps in your filling. 

One of the keys to getting perfect lemon bars is to make sure they cool completely before you decide to gobble them up. Let them cool enough that they are completely firm before eating. 

Storing the bars

Once the lemon bars have completely cooled, wrap them gently in plastic wrap so that they don’t dry out. They can be stored like this in the refrigerator for up to 4 days.
