1-First Step: Prepare the Crust Begin by lining a 9×9-inch square baking pan with parchment paper, leaving an overhang on two opposite sides. This overhang will serve as handles later, making it easy to remove the bars for cutting. In a medium bowl, combine 1 1/2 cups graham cracker crumbs with 2 tablespoons of sugar. Pour in 1/3 cup of melted butter and stir until all the crumbs are evenly moistened. Transfer the mixture to your prepared pan and press it firmly into an even layer using the bottom of a measuring cup or glass. This pressure is crucial for creating a crust that holds together when cut. Place the pan in the refrigerator to chill while you prepare the filling, about 15 minutes.

2-Second Step: Create the Cheesecake Filling In a large mixing bowl, beat 16 ounces of softened cream cheese with an electric mixer until completely smooth. It’s essential that your cream cheese is at room temperature to prevent lumps in your final filling. Add 1 cup of powdered sugar gradually, mixing well after each addition to incorporate fully. Next, add 1 cup of Nutella and 1 teaspoon of vanilla extract to the cream cheese mixture. Continue beating on medium speed until all ingredients are completely combined and the mixture is smooth and glossy. This typically takes 2-3 minutes. Scrape down the sides of the bowl occasionally to ensure everything is well incorporated.

3-Third Step: Whip the Cream In a separate chilled bowl, beat 1 1/2 cups of cold heavy whipping cream with clean beaters. Start on low speed to prevent splashing, then increase to high as the cream begins to thicken. Continue whipping until stiff peaks form, meaning the cream holds its shape when the beaters are lifted. This step adds structure and lightness to the Nutella Cheesecake Bars, preventing the filling from becoming too dense. For best results, ensure both your bowl and beaters are cold before beginning. You can chill them in the freezer for 10 minutes if needed.

4-Fourth Step: Combine and Spread Gently fold one-third of the whipped cream into the Nutella mixture to lighten it. Then add the remaining whipped cream and fold it in using a rubber spatula, being careful not to deflate the cream too much. The goal is to maintain as much air in the mixture as possible while ensuring it’s uniformly combined. Remove your crust from the refrigerator and spread the Nutella cheesecake filling evenly over it using an offset spatula or the back of a spoon. Create smooth, even strokes to achieve a professional-looking finish. Tap the pan gently on the counter once or twice to release any air bubbles.

5-Final Step: Add the Swirl and Chill Warm 1/2 cup of Nutella in the microwave for about 15-20 seconds until it’s pourable but not hot. Drizzle the warmed Nutella over the cheesecake filling in parallel lines. Use a butter knife or skewer to gently drag through the lines in a perpendicular motion, creating a beautiful marbled pattern. Don’t over-swirl, or you’ll lose the distinct design. Refrigerate the bars for at least 4-6 hours, but overnight is better for the firmest results. Once completely set, use the parchment paper handles to lift the bars from the pan. Cut into 16 squares using a sharp knife, wiping the blade clean between cuts for perfect edges.
