⏲ How to make homemade keto lemon bars

This is an overview of the recipe’s instructions. The full instructions can be found in the recipe card at the bottom of this post.

• Mix together sunflower seed meal, shredded coconut, powdered monk fruit sweetener, and salt, then mix in add melted butter, egg, and vanilla extract.
• Transfer that mixture to a baking pan and press into an even layer before transferring the pan to the oven and baking until the edges of the crust are golden brown.
• Mix together powdered monk fruit sweetener, sunflower seed meal, eggs, lemon, juice, and lemon zest and. Allow the bowl to sit for a minute to see if any egg floats to the top and appears to be un-mixed. If so, mix again until eggs are fully mixed and incorporated.
• Remove the pan with the crust from the oven and place it in the center of a large baking sheet. Then, pour the lemon filling atop the crust, then pour enough water into the baking sheet to fill it up ~1/2 inch.

• Transfer the baking sheet to the oven to bake until the filling has set.
• Turn the oven off and, using a wooden spoon, crack the oven door open just slightly. Allow the pan to sit in the cooling oven for 1 hour.
• Remove the baking sheet from the oven, remove the pan from the water bath, then transfer the pan to the refrigerator to chill uncovered for 2 hours before slicing into 16 bars and serving.

👉 Ingredient substitution suggestions

• Ground Sunflower Seed Meal: If you can eat nuts, you can substitute almond flour at a 1:1 ratio substitution. Alternatively, make ground sunflower seed meal by pulsing raw sunflower seeds in a blender or food processor until they turn into flour. Be careful not to over-blend, as doing this will make sunflower seed butter, which has a consistency similar to that of peanut butter or almond butter.
• Unsweetened Shredded Coconut: Unsweetened coconut flakes can be used in place of shredded coconut in this recipe, but you will need to pulse them in a food processor to get the right consistency for the crust.
• Powdered Monk Fruit Sweetener in Crust: Classic Monk Fruit Sweetener, Golden Monk Fruit Sweetener, Swerve, or erythritol can be used here at a 1:1 substitution ratio by cups, not by weight (meaning, for example, use ¼ cup (48g) of Classic Monk Fruit Sweetener, rather than the 30g of Powdered Monk Fruit Sweetener that is listed in the Ingredients list). I would not use powdered stevia or liquid stevia. Allulose will work at a 1:1 sub here.
• Butter: Coconut oil can be subbed in for melted butter at a 1:1 ratio, which would make these lemon bars dairy-free. If you use oil in place of butter, the crust may be denser than the original recipe intended.
• Powdered Monk Fruit Sweetener in Lemon Filling: Pulse ½ cup of Classic Monk Fruit Sweetener, Golden Monk Fruit Sweetener, or erythritol in a food processor to yield a substitution for powdered sweetener. Allulose should work at a 1:1 sub here, too!
• Lemon Juice: Lime juice can be substituted for lemon juice at a 1:1 ratio. However, if you opt for this trade, you will end up with keto lime bars.
• Lemon Zest: Lime zest could be substituted for lemon here as well but would change the flavor profile.

Keep in mind that any changes you make to this recipe will modify the total net carbs.
