These delicious keto lemon bars bring the perfect balance of sweet and tangy flavors to your kitchen!
Made with simple ingredients like almond flour and fresh lemon, they’re a wonderful treat that fits perfectly into your low carb lifestyle.
When you’re following a keto diet, finding desserts that actually taste good can be challenging.
Many store bought options are either too expensive or filled with artificial ingredients that don’t quite hit the spot.
That’s why I love making these lemon bars at home. The combination of real butter, fresh lemon zest, and almond flour creates a texture that’s very similar to traditional lemon bars.
You won’t believe these are low carb when you taste them. The sour cream adds moisture and richness, while the erythritol provides just the right amount of sweetness without any strange aftertaste.

✨ Recipe Ingredients
👨🍳 How To Make
Follow this easy recipe:
Step 1
Start by preheating the oven to 350°F and lining a pan (I used a 9×6 one) with parchment paper.
Step 2
Add the eggs to a medium bowl. Beat them until frothy. Then, add the softened butter and sour cream and blend using an electric mixer (or food processor) until well combined.
Step 3
Add the grated zest, lemon juice, and powdered erythritol. Blend well.
Step 4
Add in the almond flour and baking powder and mix until the batter is smooth. Then, transfer the batter to the prepared pan.
Step 5
Bake in the center of the oven for 37-40 minutes until the top is lightly browned. You can insert a toothpick in the center – if it comes out clean, you know it’s ready.
Step 6
Remove from the oven and let it cool for 20 minutes. You can sprinkle more powdered sweetener on top. Enjoy!
💡Tips
1. Don’t Skip the Parchment Paper
Line your baking pan with parchment paper, leaving some hanging over the sides. These bars can stick to the pan, even with butter or cooking spray.
The parchment paper helps you lift the entire batch out easily once they’re cooled, making it much simpler to cut clean, even squares.
Make sure the paper goes up all sides of the pan – this prevents any batter from seeping underneath and sticking.
2. Cooling Is Important
Don’t rush the cooling process. These bars need the full 20 minutes of cooling time to set properly. If you try to cut them too soon, they’ll be too soft and messy.
After the initial cooling period, you can speed up the process by placing them in the fridge, but don’t skip the room emperature cooling step entirely. The gradual cooling helps develop the proper texture.
When you do cut them, use a sharp knife and clean it between cuts for the neatest squares.

FAQ
1. My bars cracked on top – what did I do wrong?
Sometimes it’s from the oven temperature being slightly too high, or from opening the oven door too often while baking. A sudden temperature change can cause cracks.
However, small cracks don’t affect the taste at all, and you can easily hide them with a dusting of powdered erythritol.
2. How do I know when they’re completely done baking?
Besides the toothpick test (inserting a toothpick in the center should come out clean), look for these signs: the top should be light golden brown, not dark.
The edges should be set and slightly pulled away from the sides of the pan; and there should be no jiggling in the center when you gently shake the pan.
