Can Cheesecake Be Made Without a Crust?
Absolutely! A crustless cheesecake is a fantastic option for those seeking a lighter dessert or a gluten-free alternative. Without the graham cracker base, the focus shifts entirely to the decadent, creamy filling, allowing its bright lemon flavor to truly shine. Opting for a crustless version also significantly reduces preparation time, as there’s no need to mix, press, or pre-bake a crust. This makes it an ideal choice when you’re short on time but still crave a luxurious homemade treat. Simply prepare your lemon cheesecake filling and bake it directly in a greased pan for a beautifully smooth, elegant dessert that caters to various dietary preferences.

I don’t know about you, but I consider lemon to be one of the most incredible fruits to bake with. Its vibrant, sunshine-y color instantly brightens any dish, and its distinctive tangy flavor adds a refreshing zest that can lift even the dreariest of days. Beyond its aesthetic appeal and delightful taste, lemons offer unparalleled versatility in the kitchen. Plus, the convenience of year-round availability means you never have to worry about them being out of season, making lemon-infused desserts a possibility any time the craving strikes. For our Lemon Blueberry Cheesecake Squares, we harness the full power of this citrus marvel, utilizing both its aromatic zest and its freshly squeezed juice to achieve a deep, authentic lemon flavor that truly sings.
Are Lemons Good For You?
Beyond their culinary appeal, lemons are packed with an impressive array of vitamins and antioxidants, solidifying their status as one of the healthiest fruits available. They are an excellent source of dietary fiber, essential for digestive health, and a powerhouse of Vitamin C, crucial for immune support and skin vitality. Additionally, lemons provide beneficial amounts of Vitamin B6, calcium, potassium, and copper, alongside thiamin, riboflavin, pantothenic acid, iron, and magnesium. These nutrients contribute to overall well-being, from boosting energy to supporting bone health. For the brightest and most authentic lemon flavor in our cheesecake squares, it’s crucial to use freshly squeezed lemon juice rather than bottled varieties. Bottled lemon juice often contains preservatives and can have a more artificial, overly tart taste that doesn’t yield the best results in delicate baked goods. Always opt for fresh lemons to ensure your cheesecake has that perfectly balanced, natural tang.
The delightful homemade blueberry sauce, which elevates these cheesecake squares to an extra special treat, is surprisingly simple to prepare. It’s made by gently heating fresh (or frozen) blueberries with a touch of water and sugar in a saucepan until the berries burst and the mixture thickens into a glossy, vibrant topping. This versatile sauce can be prepared in advance, allowing you to assemble your dessert with ease, or whipped up right before serving for maximum freshness. Its sweet-tart profile is not only perfect for cheesecake but also incredibly delicious drizzled over breakfast favorites like fluffy waffles and buttermilk pancakes, adding a burst of fruity flavor to any meal.
Are Blueberries Healthy?
Blueberries are often lauded as a superfood, and for good reason. These tiny powerhouses are brimming with nutrients and antioxidants, particularly anthocyanins, which give them their distinctive deep blue hue and are responsible for many of their health benefits. They are an excellent source of Vitamin K, vital for blood clotting and bone health, and also provide a good amount of Vitamin C and dietary fiber. Nutritionists frequently highlight blueberries as one of the best single additions you can make to your diet due to their high antioxidant levels and potential to support heart health, brain function, and reduce inflammation. Incorporating these juicy berries into your diet, whether fresh, frozen, or in a delicious sauce like the one for our cheesecake, is a simple yet effective way to boost your nutritional intake and enjoy a delicious treat at the same time.

While creating these heavenly Lemon Blueberry Cheesecake Bars isn’t overly complicated, a few essential tips will ensure your cheesecake turns out perfectly smooth, creamy, and free from cracks. Mastering these simple techniques will lead to a truly luxurious dessert that looks as good as it tastes. From preparing your ingredients to the crucial cooling process, each step plays a vital role in achieving that ideal cheesecake texture and appearance that will make your efforts truly worthwhile.
Tips for Making the Perfect Cheesecake
- Room Temperature Ingredients are Key: Always ensure all your dairy ingredients, especially cream cheese, eggs, and sour cream, are at room temperature before you begin mixing. Softened cream cheese blends smoothly, preventing lumps, and room temperature eggs and sour cream integrate better into the batter, resulting in a homogenous, creamy texture.
- Choose Full-Fat, Brick-Style Cream Cheese: For the most luxurious flavor and the classic dense, creamy texture, always opt for full-fat, brick-style cream cheese. Whipped or spreadable cream cheese varieties contain too much air or water, which can negatively affect the cheesecake’s structure and richness.
- Beat Cream Cheese Thoroughly: It’s absolutely crucial to beat your cream cheese very well until it’s incredibly smooth and fluffy before adding other ingredients. This step ensures there are no lumps in your final cheesecake, providing a silky-smooth consistency. Scrape down the sides of the bowl frequently during this process.
- A Little Flour Prevents Cracks: Incorporating a small amount of all-purpose flour into the batter acts as an insurance policy against cracks. The flour helps to stabilize the egg proteins, reducing the likelihood of the cheesecake cracking during baking and cooling due to temperature changes.
- Don’t Overbake: A perfectly baked cheesecake will still have a slight wobble in the center (about 2-3 inches in diameter) if you gently nudge the pan. The residual heat will continue to cook it as it cools, resulting in a creamy, set center. Overbaking leads to a dry, cracked cheesecake.
- Cool Slowly to Prevent Cracks: Rapid temperature changes are the primary cause of cheesecake cracks. After baking, turn off your oven, crack the door open about 6 inches, and allow the cheesecake to cool slowly inside the oven for approximately one hour. Then, remove it and let it cool completely to room temperature on a wire rack before chilling.
- Embrace Imperfections: If, despite your best efforts, your cheesecake develops a few cracks, don’t despair! That’s what the luscious blueberry sauce (or any topping you choose) is for – it beautifully conceals any minor flaws, making your dessert look picture-perfect.
- Always Chill Thoroughly: Chilling your cheesecake is non-negotiable for the best flavor and texture. Once cooled to room temperature, cover the pan tightly with cling film and refrigerate for at least 4 hours, or ideally, overnight. Chilling allows the flavors to meld and the cheesecake to fully set, resulting in that wonderfully firm yet creamy consistency.

The combination of rich, creamy cheesecake, the bright, invigorating tang of lemon, and the sweet, juicy burst of blueberries is truly one of my all-time favorites. These Lemon Blueberry Cheesecake Squares embody everything wonderful about a decadent dessert, offering a harmonious blend of flavors and textures that dance on your palate. I genuinely hope you enjoy making and savoring these delightful treats as much as my family and I do!

For the Blueberry Sauce
- 3 Cups Fresh Blueberries (frozen work too)

- 1/4 Cup Granulated Sugar
Instructions
-
Make the Cheesecake
-
Before getting started, ensure your cream cheese, eggs, and sour cream are at room temperature.
-
Cream cheese can be softened more quickly by cutting it into pieces and microwaving in short 15-second bursts.
-
Preheat the oven to 350°F (175°C) and adjust your oven rack to the center.
-
Line a 9×13 inch glass pan with aluminum foil, leaving an overhang on the sides for easy lifting, and lightly grease with non-stick cooking spray. Set aside.
-
To make the graham cracker crust, mix together the graham cracker crumbs and sugar in a medium bowl.1 1/2 Cups Graham Cracker Crumbs, 1 Tablespoon Granulated Sugar
-
Then, stir in the melted butter until the crumbs are evenly moistened.6 Tablespoons Melted Butter
-
Pour the mixture into the bottom of your prepared pan and press the crumbs down firmly and evenly using the bottom of a measuring cup or your palms until it forms a compact layer.
-
Bake the crust in your preheated oven for 8 minutes. Remove from oven and let cool slightly while you prepare the filling.
-
To make the cheesecake filling, first beat the softened cream cheese in a large bowl using a stand mixer or hand-held electric mixer on medium speed until it is completely smooth and free of lumps.24 Ounces Brick-Style Cream Cheese
-
Next, beat in the granulated sugar, fresh lemon zest, and vanilla extract until everything is evenly combined and creamy.1 Cup Granulated Sugar, 2 Tablespoons Fresh Lemon Zest*, 1 teaspoon Vanilla Extract
-
Turn off your mixer and scrape down the sides of your bowl thoroughly with a rubber spatula. Then, gently stir in the freshly squeezed lemon juice and room temperature sour cream until just combined.1/3 Cup Freshly Squeezed Lemon Juice, 1/2 Cup Sour Cream
-
Turn the mixer back on to low speed and beat in the eggs one at a time, mixing just until each egg is incorporated, then add the flour. Be careful not to overmix the batter after adding the eggs, as this can introduce too much air and lead to cracks.4 Large Eggs, 2 Tablespoons Flour
-
Pour the smooth cheesecake batter evenly into your prepared pan, on top of the graham cracker crust. Gently smooth the top with your rubber spatula.
-
Bake in the preheated oven for 40-50 minutes, or until the edges appear set and the center still has a slight, gentle wobble when the pan is lightly nudged.
-
Once baked, turn off the oven, open the oven door about 6 inches, and allow the cheesecake to cool slowly in the oven for about 1 hour. This gradual cooling prevents cracking.
-
Remove the cheesecake from the oven and continue cooling on a wire rack until it reaches room temperature.
-
Cover the pan tightly with cling film and chill in the refrigerator for at least 4 hours, or preferably overnight, for the best texture and flavor development.
-
Make the Blueberry Sauce
-
In a medium saucepan over low-medium heat, combine the blueberries, water, and sugar.3 Cups Fresh Blueberries, 1/2 Cup Water, 1/4 Cup Granulated Sugar
-
Allow the mixture to gently simmer, stirring occasionally, for about 10-15 minutes, or until the blueberries soften and the sauce thickens to your desired consistency.
-
If the mixture seems too thick, you can add a little extra water, one tablespoon at a time, until it reaches the desired consistency. Remove from heat and let cool.
-
To Serve Your Cheesecake
-
Remove the chilled cheesecake from the fridge and allow it to warm up slightly for about 30 minutes before cutting.
-
Using the aluminum foil overhang, carefully lift the cheesecake out of the pan and transfer it to a cutting board. Cut into squares (approximately 18-21 pieces, depending on your desired size) and serve generously topped with the cooled blueberry sauce and, optionally, a dollop of whipped cream.
Recipe Notes
**Make sure to use freshly squeezed lemon juice. Do not use lemon juice from a bottle, as it often has a more artificial and overly tart flavor unsuitable for baking.
Store any leftover cheesecake squares in an airtight container in the refrigerator for up to 5 days. The blueberry sauce can be stored separately in the fridge for up to a week.
