Let’s get started!
HOW TO MAKE KETO LEMON BARS
For the crust:
Let’s started off by preheating your oven to 350F and grease a 9×9 baking dish.
Combine the almond flour, butter and 3 tablespoons of powdered lakanto Sweetener in a large bowl.
Pour the crust mixture into the casserole dish and flatten with a flat bottom cup.
Bake in the pre-heated oven for 25 minutes or until golden brown.
Remove from the oven and set aside.
For the filling:
Combine the eggs, powered sweetener, xanthan gum, lemon juice and salt.
You will want the mixture to be completely smooth so you can blend it in a blender or use an immersion blender.
Pour this mixture on top of the crust and cook in the oven for 15 minutes more.
Remove from the oven to cool for 10 minutes.
Sift a little extra powdered sweetener over the top and cut into 9 squares.
Serve and enjoy the perfect balance of sweet and tangy in every keto bite! Absolutely delicious!

These were so good. And easy Definitely one of my new favorites. Thanks for sharing.
Debra says
I have made this recipe three times. The first time I missed the word “melted” butter so I just naturally cut the butter into the almond flour as I would in normal baking and it turned out amazing. The next time I added melted butter to the almond flour and I didn’t like it as much. Third time I went back to cutting in the butter and the crust comes out nice and flaky.
Linda says
