Cooking Method for Keto Lemon Bars

Making these Keto Lemon Bars is a straightforward process that anyone can follow. With just a few simple steps, you’ll have a deliciously sweet and tangy treat ready to enjoy. Let’s dive into the cooking method!
- Preheat your oven to 175 degrees Celsius (350 degrees Fahrenheit). This step is crucial as it ensures that the Keto Lemon Bars bake evenly and thoroughly.
- In a mixing bowl, beat the eggs until frothy. This process incorporates air, which will help your bars become light and fluffy.
- Next, add in the sour cream and softened butter. Using a food processor or electric mixer, blend these ingredients until they are well combined and the mixture is smooth.
- Add the lemon juice, the grated zest of the lemon, and the powdered erythritol. Blend again until everything is evenly mixed. You should see a lovely yellow batter developing!
- At this point, gradually incorporate the almond flour and baking powder. Mix until you have a smooth batter; there should be no lumps left.
- Prepare a 9×6 inch pan by lining it with parchment paper. This will make it easier to remove the bars once they’ve cooled.
- Pour the batter into the prepared pan, spreading it evenly. It should fill the pan nicely.
- Place the pan in the middle shelf of the preheated oven and bake for 35 to 40 minutes. You’ll know they’re done when the top is lightly browned and a skewer inserted comes out clean.
- Once baked, remove the bars from the oven and let them cool completely in the pan. It’s important to be patient here, as cutting them while warm can cause them to fall apart.
- After the bars have cooled, carefully lift them out of the pan using the parchment paper. Cut into squares and enjoy your delicious Keto Lemon Bars!
Things Worth Knowing
- Eggs are vital: Ensure your eggs are at room temperature for better emulsification.
- Almond flour nuances: Different brands have varying textures; adjust baking time if using super-fine flour.
- Baking tips: If your bars look too brown on top, consider covering them with foil during the last 10 minutes of baking.
- Cooling is key: Allow the bars to cool completely to avoid a crumbly texture, which almond flour tends to do when warm.
