What Type of Sweetener is Best for Low Carb – Keto Lemon Bars?

I have used Truvia, Swerve, Erythritol, and monk fruit in this recipe. Pick what is best for your sweet tooth.

All of the options I mentioned have a low or zero glycemic impact on glucose levels.

Ironically, when I share altered recipes no one notices that I didn’t use granulated sugar or wheat in the recipe!

If you are new to lowering your sugar intake, then I suggest first trying the Truvia cane sugar blend, which contains some sugar with stevia and erythritol.

What Can I Use In Place of Coconut Oil?

I have used coconut oil in the crust as well as butter. You can also experiment with other cooking oils like vegetable oil.

The Crust For These Lemon Bars is Runny. What Happened?

The crust should firm up after about five minutes of mixing the ingredients for the crust. The coconut flour will absorb some of the moisture.

To troubleshoot, some readers have told me they put the crust in the refrigerator for about 10 minutes and it firms up.

You can also add a sprinkle of more coconut flour but don’t go overboard otherwise you will have a hard crust.

How to Make This Keto Lemon Bars Recipe

Making this homemade dessert takes two simple steps. First, you make the crust, and then you make the lemon filling. To make these soft lemon bars follow the simple step-by-step instructions below.

Step 1: Preheat the oven and prepare your baking dish

Preheat oven to 350°F. Line an 8″ x 8″ baking dish with parchment paper and set aside.

Step 2: Melt the coconut oil

For the crust melt the butter or coconut oil in the microwave until it liquefies. Add powdered sugar, and egg yolk and stir until blended.

Step 3: Mix together the crust

In a small separate bowl whisk together the almond and coconut flour with the salt. Add to liquid and mix forming a dough.

Step 4: Bake the crust

Press onto the bottom of the prepared pan and bake for 20 minutes or until lightly brown. Cool on a baking rack.

Step 5: Make the lemon filling

For the lemon filling in a medium bowl beat the eggs and Truvia with an electric hand mixer until smooth. Add the lemon juice and zest. Fold in the almond flour.

Step 6: Bake the lemon bars

Pour over the crust and bake for about 20 minutes or until the filling has set. Cool on a baking rack and refrigerate for about an hour before cutting.

Step 7: Garnish before serving

Garnish with powdered sugar and the fruit of your choice.

Sandra’s Pro Tips

Here are a few of my tips to help you make the best low-carb lemon bars:

• Make sure your ingredients are at room temperature before starting this recipe. This will ensure that the dough comes together properly.
• Be careful not to overbake so the bars don’t dry and crumble. The middle should still be slightly jiggly when you remove them from the oven.
• For a nice presentation, be sure to dust with powdered sugar or Swerve before serving.
• You can tip these bars with sliced fresh lemons, or sweet berries.
• Don’t skip the parchment paper, that helps to easily remove the bars for even cutting.
