Everything You Need To Make This Recipe Without Stress

Gathering your ingredients before you start is key to a smooth baking experience. This recipe uses common keto-friendly staples, making it easy to whip up these delicious bars whenever the craving strikes.

INGREDIENTS:

• 1 cup almond flour, superfine
• 1/4 cup erythritol or monk fruit sweetener, granulated, for the crust
• 1/4 cup unsalted butter, melted
• 16 ounces cream cheese, softened
• 1/2 cup erythritol or monk fruit sweetener, granulated, for the filling
• 2 large eggs
• 1/4 cup heavy cream
• 1 tablespoon lemon zest
• 2 tablespoons fresh lemon juice
• 1 teaspoon vanilla extract
• 1/2 cup fresh blueberries, or frozen (do not thaw)

For the sweeteners, feel free to use your preferred granulated erythritol or monk fruit blend. Swerve and Lakanto are popular brands that work well. If you don’t have fresh blueberries, frozen ones are a great substitute; just be sure not to thaw them before adding them to the batter to prevent them from bleeding too much color into the cream cheese layer.

Time Needed From Start To Finish

This recipe is designed for efficiency, allowing you to enjoy these delicious bars without spending hours in the kitchen.

• Preparation time: 15 minutes
• Baking time: 30-35 minutes
• Chilling time: 2-3 hours (minimum)
• Total time: Approximately 3 hours 45 minutes (including chilling)

While the active prep and bake time is under an hour, the chilling time is crucial for the bars to set properly and achieve their best texture, so plan accordingly.

How To Make It Step By Step With Visual Cues

Creating these keto blueberry lemon bars is a straightforward process. Follow these steps for a perfect outcome every time.

1. Prepare the Crust: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the bars out later. In a medium bowl, combine the almond flour and 1/4 cup granulated sweetener for the crust. Pour in the melted butter and mix until well combined and crumbly. Press this mixture evenly into the bottom of the prepared baking pan. Bake for 10-12 minutes, or until lightly golden brown. Remove from the oven and let cool slightly while you prepare the filling.

1. Make the Cream Cheese Filling: In a large mixing bowl, using an electric mixer, beat the softened cream cheese until smooth and creamy, about 2-3 minutes. Make sure there are no lumps.

1. Add Sweetener and Eggs: Gradually add the remaining 1/2 cup granulated sweetener to the cream cheese, beating until fully incorporated. Beat in the eggs one at a time, mixing well after each addition until just combined. Be careful not to overmix the eggs.

1. Incorporate Flavorings: Stir in the heavy cream, lemon zest, fresh lemon juice, and vanilla extract until the mixture is smooth and evenly flavored. The mixture should be thick and pourable.

1. Assemble the Bars: Pour the cream cheese filling evenly over the cooled crust in the baking pan. Gently sprinkle the fresh or frozen blueberries over the top of the cream cheese layer. You can gently press some of them down slightly if you wish, but don’t submerge them completely.

1. Bake the Bars: Return the pan to the oven and bake for 30-35 minutes, or until the edges are set and the center is mostly firm with a slight jiggle. The top might be lightly golden.

1. Cool and Chill: Remove the pan from the oven and let the bars cool completely at room temperature on a wire rack. Once cooled, transfer the pan to the refrigerator and chill for at least 2-3 hours, or preferably overnight, until thoroughly set. This chilling step is essential for firm, sliceable bars.

1. Slice and Serve: Once chilled, use the parchment paper overhang to lift the entire slab of bars out of the pan. Place on a cutting board and slice into 9 or 16 squares, depending on your desired serving size. Serve cold.

Easy Variations And Serving Ideas That Fit Real Life

These keto blueberry lemon bars are wonderfully versatile. For a fun twist, you could swirl in a tablespoon of sugar-free lemon curd into the cream cheese mixture before baking for an extra punch of lemon flavor. If blueberries aren’t your favorite, try swapping them for raspberries or blackberries, which are also low in carbs. For a decorative touch, a light dusting of powdered erythritol (sifted through a fine-mesh sieve) just before serving adds an elegant finish. These bars are perfect for a casual family dessert, a sophisticated addition to a brunch spread, or a delicious contribution to a potluck. They hold up well, making them excellent for meal prepping your weekly keto treats.

Common Slip-Ups And How To Avoid Them

Even simple recipes can have common pitfalls. Here are a few to watch out for to ensure your blueberry lemon bars turn out perfectly.

• Overmixing the Filling: When adding the eggs to the cream cheese mixture, mix just until they are incorporated. Overmixing can introduce too much air, leading to cracks in the top of your bars as they cool.
• Not Softening Cream Cheese: If your cream cheese isn’t at room temperature, it will be lumpy and difficult to beat smooth, resulting in a grainy texture in your filling. Plan ahead and let it sit out for at least an hour.
• Skipping the Chilling Time: This is perhaps the most crucial step for bars. If you try to slice them before they are fully chilled, they will be too soft and messy. Patience is key here for clean, firm slices.
• Overbaking the Crust: Keep an eye on the almond flour crust during its initial bake. Almond flour can brown quickly, and an overbaked crust will be dry and crumbly.
• Thawing Frozen Blueberries: If using frozen blueberries, add them directly to the filling without thawing. Thawed blueberries release too much moisture and can make your bars watery or cause the color to bleed excessively.

How To Store It And Make It Ahead Without Ruining Texture

Proper storage is essential to keep your keto blueberry lemon bars fresh and delicious. Once cooled and sliced, store the bars in an airtight container in the refrigerator. They will maintain their best texture and flavor for up to 5-7 days. For longer storage, you can freeze them. Place the sliced bars on a baking sheet lined with parchment paper and freeze until solid, about 1-2 hours. Once frozen, transfer them to a freezer-safe bag or container, separating layers with parchment paper to prevent sticking. They can be stored in the freezer for up to 2-3 months. Thaw individual bars in the refrigerator overnight or at room temperature for about 30 minutes before enjoying. These bars are excellent for making ahead for parties or for having a ready-to-eat keto treat on hand.

Questions People Always Ask Before Making This Recipe

Can I use a different type of flour for the crust?

No, for this specific keto recipe, almond flour is essential. Other flours like coconut flour have different absorption rates and would require significant adjustments to the recipe. Regular flour is not low-carb.

Can I use sugar instead of erythritol/monk fruit?

While you technically could, this would no longer be a keto-friendly recipe. To keep it low-carb, stick to the recommended sugar substitutes.

My bars cracked on top, what happened?

Cracks usually occur from overmixing the filling (introducing too much air) or overbaking. Ensure you mix just until combined and don’t bake longer than necessary.

Can I make these dairy-free?

You could experiment with dairy-free cream cheese and heavy cream alternatives, but the texture and flavor might vary. I haven’t tested this version myself.

Why do I need to chill the bars for so long?
