Ingredients

This recipe is broken down into three simple components.

For the Shortbread Crust:

  • 1 ½ cups (190g) all-purpose flour

  • ½ cup (100g) granulated sugar

  • ¼ teaspoon salt

  • ½ cup (1 stick / 113g) cold unsalted butter, cut into small cubes

  • 1 large egg yolk

For the Creamy Cheesecake Filling:

  • 16 oz (452g) full-fat cream cheese, softened to room temperature

  • ½ cup (100g) granulated sugar

  • 2 large eggs, at room temperature

  • ¼ cup (60g) sour cream, at room temperature

  • 2 tablespoons all-purpose flour

  • 1 tablespoon fresh lemon zest (from about 1 large lemon)

  • 2 tablespoons fresh lemon juice

  • 1 teaspoon vanilla extract

For the Blueberry Swirl:

  • 1 ½ cups (about 200g) fresh or frozen blueberries (if using frozen, do not thaw)

  • 1 tablespoon granulated sugar

  • 2 teaspoons fresh lemon juice

  • 2 teaspoons cornstarch


Instructions

Let’s break this down step-by-step. Follow along, and you’ll be a pro.

Part 1: Prepare the Blueberry Swirl

  1. In a small saucepan, combine the blueberries, 1 tablespoon of sugar, and 2 teaspoons of lemon juice.

  2. Place over medium heat and cook, stirring occasionally, for about 5-8 minutes, until the blueberries have burst and released their juices.

  3. In a small bowl, whisk the cornstarch with 1 tablespoon of cold water to form a slurry.

  4. Pour the slurry into the blueberry mixture and stir continuously. Cook for another 1-2 minutes, until the mixture has thickened significantly. It should coat the back of a spoon.

  5. Remove from heat and set aside to cool completely while you prepare the crust and filling.

Part 2: Make the Shortbread Crust

  1. Preheat your oven to 350°F (175°C). Line a 9×9-inch square baking pan with parchment paper, leaving some overhang on two opposite sides. This will be your “sling” to lift the bars out later.

  2. In a medium bowl, whisk together the 1 ½ cups of flour, ½ cup of sugar, and salt.

  3. Add the cold, cubed butter. Using a pastry blender or your fingertips, cut the butter into the flour mixture until it resembles coarse meal with some pea-sized butter bits remaining.

  4. Add the egg yolk and stir with a fork until the dough clumps together. It will be crumbly but should hold together when pressed.

  5. Pour the crust mixture into your prepared pan and press it firmly and evenly into the bottom. Using the flat bottom of a measuring cup or glass helps get a nice, even layer.

  6. Bake the crust for 18-20 minutes, or until it’s lightly golden around the edges. Remove from the oven and set aside. Keep the oven on.

Part 3: Create the Cheesecake Filling

  1. While the crust is baking, make the filling. In a large mixing bowl, beat the softened cream cheese with an electric hand mixer (or in a stand mixer with the paddle attachment) until it’s completely smooth and free of lumps.

  2. Add the ½ cup of sugar and beat until combined and creamy, scraping down the sides of the bowl as needed.

  3. Add the eggs one at a time, beating on low speed just until each is incorporated. Do not overmix.

  4. Add the sour cream, 2 tablespoons of flour, lemon zest, lemon juice, and vanilla extract. Mix on low speed until the batter is smooth and uniform. Scrape the bowl one last time.

Part 4: Assemble and Swirl

  1. Pour the cheesecake filling over the warm pre-baked crust. Gently spread it into an even layer with a spatula.

  2. Take your cooled blueberry mixture. If it’s very thick, give it a quick stir. Drop spoonfuls of the blueberry sauce randomly over the top of the cheesecake filling.

  3. Take a knife or a toothpick and gently swirl it through the filling and blueberry mixture to create a marbled effect. Be careful not to drag the knife all the way to the crust—just swirl through the top layer.

Part 5: Bake and Cool

  1. Place the pan in the oven and bake for 45-55 minutes. The edges will look set, but the center will still have a slight jiggle when you gently shake the pan. This is the sign of a perfect, creamy cheesecake.

  2. Turn the oven off and crack the oven door open. Let the cheesecake bars cool in the oven for 1 hour. This gradual cooling helps prevent cracks.

  3. After an hour, remove the pan from the oven and place it on a wire rack to cool completely to room temperature.

  4. Once cool, cover the pan with plastic wrap and refrigerate for at least 4 hours, but preferably overnight. This chilling time is non-negotiable for clean, beautiful slices.

Part 6: Slice and Serve

  1. Once thoroughly chilled and firm, use the parchment paper sling to lift the entire block of cheesecake bars out of the pan and onto a cutting board.

  2. Use a long, sharp knife to slice the bars. For the cleanest cuts, wipe the knife clean with a damp paper towel between each slice.

  3. Serve cold and enjoy!


Storage and Make-Ahead Tips

  • Storing: Keep leftover bars in an airtight container in the refrigerator for up to 5 days.

  • Freezing: These bars freeze beautifully! Wrap individual slices or the whole unsliced block tightly in plastic wrap, then in a layer of aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
