This keto lemon bar is tangy, sweet, and super easy to make. This refreshing little treat has only 65 calories and 3 grams of carbs per serving. I love dessert with lemons! Especially lemon bars are so refreshing to enjoy. This is a keto and also low-calorie version in case someone is watching his/her diet.
These keto lemon bars are mainly made with almond flour, freshly squeezed lemon juice, and Greek yogurt. I knew we could eat butter on the keto diet, but I chose to omit it to make it lower in calories. If higher calories don’t bother you, feel free to swap unsweetened apple sauce for unsalted butter.
