Snickerdoodle Cheesecake Bars with Philadelphia Cream Cheese

Snickerdoodle cheesecake bars pair a cinnamon-sugar cookie crust and topping with a smooth Philadelphia cream cheese filling. They bake in one pan, chill until sliceable, and bring the familiar flavors of snickerdoodles together with creamy cheesecake in an easy-to-share dessert.

Ingredients

Nonstick cooking spray, for the pan
2 1/4 cups (281 g) all-purpose flour
1 teaspoon (5 g) cream of tartar
1/2 teaspoon (3 g) baking soda
1/2 teaspoon (3 g) fine salt
3/4 cup (170 g) unsalted butter, softened
3/4 cup (150 g) granulated sugar, plus 2 tablespoons (25 g) for the cinnamon topping
1 large egg, at room temperature
1 teaspoon (5 ml) vanilla extract
16 ounces (454 g) Philadelphia cream cheese, softened
1/2 cup (100 g) granulated sugar, for the filling
1 large egg, at room temperature, for the filling
1 teaspoon (5 ml) vanilla extract, for the filling
1 1/2 teaspoons (4 g) ground cinnamon, divided

Instructions

Set a rack in the middle of the oven and heat it to 350°F (175°C). Line an 8-inch (20 cm) square baking pan with parchment paper, leaving enough overhang on two sides to lift out the bars. Lightly coat the exposed sides of the pan with cooking spray.
In a medium bowl, whisk together the flour, cream of tartar, baking soda, and salt. In a separate large bowl, beat the softened butter with 3/4 cup (150 g) sugar until creamy, about 2 minutes. Beat in one egg and 1 teaspoon (5 ml) vanilla until combined. Add the flour mixture and mix on low just until no dry patches remain; the dough will be thick.
Set aside about 1 cup (roughly 220 g) of dough for the topping. Press the remaining dough evenly across the bottom of the prepared pan. Use lightly floured fingertips or the bottom of a measuring cup to make a compact, level layer. Bake for 12 minutes, then set the pan on a heat-safe surface while you make the filling. The crust will not be fully browned.
Beat the cream cheese in a clean bowl on medium-low until smooth, about 1 minute. Add the filling’s 1/2 cup (100 g) sugar and beat until blended, scraping the bowl. Add the remaining egg and the filling’s 1 teaspoon (5 ml) vanilla; mix on low just until smooth. Avoid beating in excess air, which can contribute to cracks.
Spread the cheesecake mixture evenly over the warm crust. Break the reserved dough into small pieces and scatter them over the filling. Stir the remaining 1/2 teaspoon cinnamon with 2 tablespoons (25 g) sugar, then sprinkle it evenly over the top.
Bake for 28 minutes, or until the edges look set and the center has a slight, even wobble when the pan is gently nudged. The filling will continue to firm as it cools; do not wait for the center to become completely rigid in the oven. Set the pan on a rack and cool at room temperature for 1 hour.
Cover the pan and refrigerate for at least 3 hours, until cold and firm. Lift out the slab using the parchment, cut into 16 bars with a sharp knife, and wipe the blade between cuts for neat edges. Keep the bars chilled until serving.

Tips

Soften the cream cheese and butter until they yield to a gentle press, but do not melt them. Cold cream cheese can leave lumps; melted butter can make the cookie dough greasy.
Measure flour by spooning it into the cup and leveling it, or weigh it. Scooping directly from the bag can pack in too much flour and make the crust and topping dry.
Mix the filling only until smooth, and bake to the visual cues rather than expecting a deeply browned top. A little movement in the middle is normal; overbaking can make cheesecake dry or prone to cracks.
For easier slicing, chill the bars fully and use a long, sharp knife. If the topping dough is too soft to crumble, chill it for 10 minutes while the crust bakes.

Serving Suggestions

Serve the bars cold or let them sit at room temperature for about 10 minutes for a softer, creamier bite. They are rich enough to serve on their own, but pair nicely with fresh berries, sliced apples, or unsweetened coffee or tea. For a dessert plate, add a small scoop of vanilla ice cream and a light dusting of cinnamon.

Variations

For a stronger cinnamon note, add 1/4 teaspoon ground cinnamon to the cheesecake filling. You can replace up to 1/2 cup (63 g) of the all-purpose flour with whole-wheat pastry flour; the cookie layer will taste a little nuttier and may be slightly less tender. For a gluten-free version, use a cup-for-cup gluten-free baking blend that includes a binder, following its package guidance; texture can vary by blend. A teaspoon of finely grated orange zest in the filling gives the bars a fresh citrus accent without changing the basic method.

Storage and Reheating

Because the filling contains cream cheese and egg, refrigerate the bars within 2 hours of baking or serving. Keep them covered in an airtight container in the refrigerator for 3 to 4 days. They are best served chilled or briefly tempered at room temperature; reheating is not needed and can soften the cheesecake layer. For longer storage, freeze the cut bars in a single layer until firm, then wrap or pack airtight for up to 2 months. Thaw overnight in the refrigerator.

Frequently Asked Questions

Can I use low-fat Philadelphia cream cheese?
Full-fat block cream cheese gives the filling the firmest, richest texture. Low-fat cream cheese may work, but the filling can be softer; avoid whipped or spreadable tub cream cheese, which has a different moisture and texture.

Why did my cheesecake filling crack?
Small cracks can happen if the filling is overmixed, too much air is beaten in, or the bars bake too long. They will still taste good. Mix gently, take the pan out while the center has a slight wobble, and cool it gradually.

Can I make these bars ahead?
Yes. Make them a day ahead, chill them covered, and slice shortly before serving. The overnight chill helps the filling set and makes clean cuts easier.

Can I bake this in a 9-inch (23 cm) square pan?
Yes, but the bars will be thinner and may bake faster. Begin checking around 24 minutes after adding the filling, and use the set edges and slight center wobble as your cues. The crust may also need a little less time.

Can I substitute cinnamon for cream of tartar?
No. Cream of tartar provides the characteristic snickerdoodle tang and reacts with baking soda; cinnamon adds flavor but does not replace it. If you do not have cream of tartar, use 2 teaspoons (8 g) baking powder in place of the cream of tartar and baking soda, though the cookie layer will have a milder, less traditional tang.
