These creamy cheesecake bars have a buttery graham-cracker crust and a bright berry topping, making them a crowd-friendly dessert for birthdays, potlucks, and holiday gatherings. They’re easy to portion and can be made a day ahead, so you can spend less time serving and more time with your guests.
Ingredients
- 2 cups (about 200 g) graham-cracker crumbs
- 6 tablespoons (85 g) unsalted butter, melted
- 3 tablespoons granulated sugar, divided
- 24 ounces (680 g) full-fat cream cheese, softened
- ¾ cup (150 g) granulated sugar
- 3 large eggs, at room temperature
- ½ cup (120 g) sour cream, at room temperature
- 2 teaspoons vanilla extract
- 1 tablespoon all-purpose flour
- 1 teaspoon finely grated lemon zest (optional)
- 1½ cups (about 225 g) fresh strawberries, hulled and diced
- 1 cup (about 125 g) fresh blueberries
- 2 tablespoons lemon juice
- 2 tablespoons seedless raspberry or strawberry jam
- 1 teaspoon water
Instructions
- Heat the oven to 325°F (163°C). Line a 9-by-13-inch metal baking pan with parchment paper, leaving enough overhang on the long sides to lift out the chilled bars. Lightly grease any exposed sides of the pan.
- Stir the graham-cracker crumbs with the melted butter and 2 tablespoons of the sugar until evenly moistened. Tip the mixture into the pan and press it into a firm, even layer using the bottom of a measuring cup. Bake for 10 minutes, then set the pan aside while you make the filling. Leave the oven on.
- In a large bowl, beat the softened cream cheese and remaining ¾ cup sugar on medium-low speed until smooth, about 1–2 minutes. Scrape the bowl and beaters as needed. Avoid whipping in excess air, which can make cheesecake puff and crack.
- Add the eggs one at a time, mixing on low just until each is incorporated. Mix in the sour cream, vanilla, flour, and lemon zest, if using. Stop as soon as the filling is smooth; scrape the bottom of the bowl so no lumps of cream cheese remain.
- Pour the filling over the warm crust and gently spread it to the corners. Bake for 35–42 minutes. The edges should look set while the center still has a slight, unified wobble when the pan is gently nudged. For a food-safety check, the center should reach 160°F (71°C) on an instant-read thermometer. Avoid letting the thermometer touch the pan.
- Set the pan on a rack and let the cheesecake cool at room temperature for about 1 hour. Do not leave it out for more than 2 hours total. Refrigerate, uncovered until cool if convenient, then cover and chill for at least 4 hours, preferably overnight, until firm.
- Shortly before serving, combine the strawberries, blueberries, and lemon juice in a bowl. Stir the jam with the teaspoon of water until pourable; warm it for a few seconds if needed, then fold it gently through the berries. Spoon the topping over the chilled cheesecake. For neater portions, lift the slab out by the parchment and cut it into 24 bars with a long knife, wiping the blade between cuts.
Tips
- Use room-temperature cream cheese, eggs, and sour cream for a smoother filling. If the cream cheese is cold, it can leave lumps even after extended mixing.
- For a clean crust, press the crumbs firmly but evenly into the pan; thin spots can crumble when you cut the bars. A flat-bottomed cup makes an effective tamper.
- Don’t judge doneness by a completely firm center. Cheesecake continues to set as it cools, and overbaking can make it dry or cracked. Check the center temperature without touching the pan.
- For easier serving at a party, chill the bars thoroughly and cut them before guests arrive. Keep the berry topping separate until shortly before serving if you want the crust to stay especially crisp.
Serving Suggestions
Arrange the bars on a chilled platter, leaving a little space between them so guests can pick them up easily. Offer small forks or dessert plates, especially if the topping is juicy. They pair well with coffee, black tea, or unsweetened iced tea; a bowl of extra berries lets guests add more fruit if they like.
For a buffet, keep the platter over a larger tray of ice or bring out a portion at a time. Cheesecake is perishable, so don’t leave it sitting at room temperature for more than 2 hours total, or 1 hour when the temperature is above 90°F (32°C).
Variations
Use raspberries, blackberries, or sliced peaches in place of some or all of the strawberries and blueberries. Keep the total fruit amount close to 2½ cups, and add juicy fruit just before serving. For a citrus version, replace the lemon zest with orange zest and use orange juice in the berry glaze.
To make a chocolate variation, fold ½ cup mini chocolate chips into the finished filling and omit the fruit topping. You can also serve the plain bars with a little chocolate sauce. For a gluten-free option, use certified gluten-free graham-style crumbs and check the labels on the other packaged ingredients; the filling itself contains a small amount of flour, so replace that tablespoon with cornstarch.
Storage and Reheating
Store covered cheesecake bars in the refrigerator at 40°F (4°C) or colder for up to 4 days. For best texture, keep the fresh berry topping separate and add it shortly before serving. Discard any bars that have been at room temperature for more than 2 hours, or more than 1 hour in temperatures above 90°F (32°C).
To freeze, chill the bars until firm, cut them, and freeze without the fruit topping in a single layer. Once solid, wrap each bar or separate layers with parchment in an airtight container. Freeze for up to 2 months for best quality. Thaw overnight in the refrigerator, then add fresh topping. These bars are served cold and should not be reheated.
Frequently Asked Questions
Can I make these cheesecake bars the day before?
Yes. Bake and chill them the day before, then keep the pan covered in the refrigerator. Add the berry topping just before serving for the freshest appearance and best crust texture.
How do I know when the cheesecake is done?
The edges should be set and the center should retain a slight wobble, not slosh. The center should reach 160°F (71°C) for a food-safety check. It will firm up further during chilling, so don’t wait for the whole surface to look dry and rigid.
Can I use low-fat cream cheese?
Full-fat cream cheese gives the richest texture and is less likely to make the filling soft. Lower-fat products can work, but the bars may be less creamy and may need extra chilling; avoid whipped cream cheese, which has a different texture and volume.
Why did my cheesecake crack?
Cracks can result from overmixing, overbaking, or a sudden temperature change. Mix on low after adding the eggs, remove the pan while the center still has a slight wobble, and cool it gradually. A small crack won’t affect the taste and will be covered by fruit.
Can I make the bars without a mixer?
Yes, if the cream cheese is very soft. Use a sturdy whisk or wooden spoon and work patiently until it is smooth before adding the eggs. Mix gently once the eggs go in to avoid adding too much air.
How many servings does this recipe make?
Cut the slab into 24 small bars for a party dessert spread. For larger portions, cut 16 bars instead; use a sharp knife and wipe it clean between cuts for tidy edges.
