Mixing Bowls: A good set of mixing bowls allows you to combine ingredients effortlessly. Opt for varying sizes to accommodate both dry and wet ingredients.
Electric Mixer: While a whisk will do in a pinch, an electric mixer makes it easy to achieve silky-smooth cheesecake filling without breaking a sweat.

Spatula: Use this handy tool for folding in delicate ingredients like blueberries, ensuring they stay intact and maintain their luscious juiciness.
9×13-inch Baking Pan: This size is ideal for the recipe, allowing evenly baked bars that are easy to cut and serve.
Parchment Paper or Aluminum Foil: Lining the pan with parchment or foil prevents sticking, making it easy to lift the bars out after they cool.

Preparation Tips:

Take your cream cheese out of the refrigerator ahead of time to soften, allowing it to blend smoothly into the filling.
Measure out all ingredients beforehand for a seamless baking experience.

How to Make Sugar-Free Blueberry Lemon Pie Bars

Preheat your oven: Start by setting it to 350°F (175°C). Prepare your 9×13-inch baking pan by lining it with foil, allowing some overhang for easy lifting later on.
Make the sugar-free crust: In a mixing bowl, combine the melted butter and powdered sweetener, beating them together until well combined. Gradually mix in the almond flour and salt until the dough forms a cohesive mixture. Press about 2/3 of this dough into the prepared baking pan, ensuring it’s evenly spread. Bake for 15-20 minutes or until it’s a light golden brown. Remove it from the oven and let it cool.

Prepare the lemon cheesecake filling: In another mixing bowl, beat the softened cream cheese and granulated monk fruit sweetener until mixture is smooth and creamy. Add the eggs one at a time, mixing well after each addition. Stir in the lemon zest, lemon juice, vanilla extract, and a pinch of salt, ensuring everything is well incorporated. Finally, gently fold in the fresh blueberries, preserving their integrity.
Make the crumble topping: In a small bowl, mix together the almond flour, powdered sweetener, lemon zest, and salt. Cut in the softened butter with a fork or pastry cutter until the mixture resembles crumbly sand.
Assemble and bake: Pour the creamy lemon filling over the cooled crust, making sure to spread it evenly. Scatter any remaining blueberries over the filling, followed by sprinkling the crumble topping generously. Place it back in the oven and bake for 55 minutes to an hour, until the filling is set and the crumble topping is golden brown.

Cool and glaze (optional): Allow the pie bars to cool completely for about 2 hours. If you’d like a sweet glaze, whisk together the powdered monk fruit sweetener and lemon juice until smooth; drizzle it over the cooled bars.
Cut and store: Once cooled, lift the bars out of the pan using the foil overhang and cut them into squares. Store any leftovers covered in the refrigerator for up to three days.

Chef’s Notes & Helpful Tips

Make-ahead tips: Prepare the crust and filling the day before to save yourself time. Assemble and bake when you’re ready to serve.
Cooking alternatives: If you prefer, you can make these pie bars in an air fryer. Just monitor them closely, adjusting cooking times as necessary, since air fryers may cook faster.

Customization ideas: Feel free to swap out the blueberries for raspberries or strawberries, or even add a mix of berries for a delightful twist.

Common Mistakes to Avoid

Baking these pie bars can be simple, but common mistakes can lead to undesired outcomes:

Overmixing the batter: When combining the filling ingredients, it’s easy to overmix, leading to a dense cheesecake. Mix just until combined.

Skipping the cooling time: Allowing the pie bars to cool completely before cutting is essential. Otherwise, they may fall apart and lose their shape.
Not measuring accurately: Baking requires precision. Make sure to measure ingredients carefully, especially sweeteners and flour.

What to Serve With Sugar-Free Blueberry Lemon Pie Bars

These delightful pie bars pair beautifully with a variety of beverages and accompaniments:

Whipped cream: A dollop of unsweetened whipped cream balances the tartness and adds creaminess.
Iced tea: Refreshing and light, it complements the zesty flavors of the pie bars perfectly.
Lemonade: Serve with chilled lemonade for a refreshing summer treat that echoes the lemon flavors of your bars.

Vanilla ice cream: The contrast of warm bars with cold ice cream creates an irresistible treat.
Mint tea: A warm cup of mint tea offers delightful contrast and refreshment alongside your dessert.
Berries: Serve alongside a fresh berry salad for a colorful and tasty addition.

Cheese platter: Pairing with a cheese board can create a delightful sweet and savory experience.

Storage & Reheating Instructions

Store your pie bars in the refrigerator, tightly covered, for up to three days. If you’re looking to preserve them for longer, you can freeze the baked bars. Wrap them well in plastic wrap and aluminum foil—this will maintain their quality for up to three months. Thaw in the refrigerator overnight before serving, and if you want to enjoy them warm, pop them in a preheated oven at 350°F (175°C) for about 10 minutes.
