Ingredients for Keto Lemon Cheesecake Bars

Here’s a quick overview of the ingredients needed to make these lemon cheesecake bars. For the full, printable recipe, scroll to the end of the guide. You’ll need:

  • Almond Flour: Essential for the crust, as its absorbency and texture are perfect for this recipe. Do not substitute with coconut flour as it absorbs differently.
  • Butter: Both salted and unsalted butter work well.
  • Sweetener: Confectioners monkfruit sweetener is recommended, but Swerve can also be used. If you aren’t counting carbs, regular confectioners sugar works too.
  • Egg: Use a large egg at room temperature for the best results.
  • Sour Cream: Either full-fat or reduced-fat sour cream will work.
  • Lemon Juice and Zest: Fresh lemons are best for juice and zest to impart a vibrant flavor.
  • Vanilla Extract: Pure vanilla extract is preferred for its rich flavor that complements the lemon.
  • Pecans: These are used in the crumble topping and can be substituted with walnuts or almonds if preferred.

Tools and Equipment

In addition to the ingredients, you’ll need an 8×8 inch pan, aluminum foil or parchment paper, an electric mixer, and a few mixing bowls. It’s crucial to use the correct size pan; otherwise, the bars may turn out too thin.

How to Make Lemon Cheesecake Bars

Preparing the Crust

  1. Line the Pan: Start by lining an 8×8 inch square baking pan with aluminum foil or parchment paper. Lightly spray it with cooking oil to prevent sticking.
  2. Make the Dough: Combine almond flour, sweetener, and melted butter in a mixing bowl until a thick dough forms.
  3. Press the Dough: Evenly press the dough into the prepared pan, ensuring it covers the bottom and reaches the edges.

Creating the Lemon Cheesecake Layer

  1. Mix the Ingredients: In a mixing bowl, combine cream cheese, sour cream, egg, sweetener, lemon zest, lemon juice, and vanilla extract.
  2. Blend Until Smooth: Use an electric mixer to blend the mixture until smooth and creamy.
  3. Spread Over Crust: Spoon the cheesecake mixture over the crust and spread it evenly with an offset spatula.

Making the Pecan Crumble Topping

  1. Prepare the Crumble: For the crumble topping, combine cold butter, almond flour, pecans, and sweetener in a food processor. Pulse until the mixture resembles coarse crumbs. Alternatively, use a bowl and a pastry cutter.
  2. Sprinkle Over Cheesecake: Sprinkle the crumb mixture over the lemon cheesecake layer.

Baking the Bars

  1. Preheat the Oven: Preheat your oven to 350°F (175°C).
  2. Bake: Place the pan in the oven and bake for 25-30 minutes. Monitor the bars around the 15-20 minute mark; if the crumble topping is browning too quickly, loosely cover with foil to prevent over-browning.
  3. Cool Down: Allow the bars to cool to room temperature before placing them in the refrigerator. Chill for at least 2 hours before slicing.

Tips for the Best Lemon Cheesecake Bars

Use High-Quality Ingredients

Opt for high-quality cream cheese, fresh eggs, freshly squeezed lemon juice, and pure vanilla extract for the best flavor.

Room Temperature Ingredients

Proper Baking Time and Temperature

Storage and Freezing

  • Freezing: Wrap the bars in plastic wrap, then place them in an airtight container or freezer bag. They can be frozen for up to 3 months. Thaw at room temperature or in the fridge overnight.
