Print Recipe

These black cocoa spiderweb cheesecake bars feature a deep, Oreo-like flavor from black cocoa powder, a creamy cheesecake layer, and a stunning spiderweb pattern made with sour cream. They’re an easy, make-ahead Halloween dessert that looks professional but requires no special skills.

Ingredients

Scale
  • 1 ½ cups chocolate graham cracker crumbs (about 10–12 full sheets, crushed finely)
  • ¼ cup black cocoa powder (for crust)
  • ¼ cup granulated sugar (for crust)
  • 6 tablespoons unsalted butter, melted
  • Pinch of salt
  • 16 ounces (two 8-ounce blocks) cream cheese, softened to room temperature
  • ½ cup granulated sugar (for filling)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ¼ cup sour cream (for filling), room temperature
  • 2 tablespoons black cocoa powder (for filling), sifted
  • ¼ cup sour cream (for topping)
  • 1 tablespoon granulated sugar (for topping)
  • 1 teaspoon milk or cream (for topping)

Instructions

  1. Preheat oven to 325°F (163°C). Line a 9×9-inch baking pan with two strips of parchment paper that cross each other, leaving about 2 inches of overhang on each side. Lightly spray with nonstick spray.
  2. Make the crust: In a food processor or zip-top bag, crush chocolate graham crackers into fine crumbs. Transfer to a medium bowl and whisk in black cocoa powder, sugar, and salt. Pour in melted butter and stir with a fork until evenly moistened (like wet sand). Press firmly into the bottom of the prepared pan using a flat measuring cup. Bake for 10 minutes, then set aside to cool. Keep oven on.
  3. Make the cheesecake filling: In a large bowl, beat softened cream cheese with an electric mixer on medium speed until smooth and fluffy, about 2 minutes. Scrape down sides. Add sugar and beat for another minute. Add eggs one at a time, beating on low after each just until incorporated. Add vanilla and ¼ cup sour cream, mix on low until smooth. Sift 2 tablespoons black cocoa powder over batter and fold in gently with a spatula until uniform in color.
  4. Assemble: Pour cheesecake filling over cooled crust and spread evenly. Tap pan gently on counter to release air bubbles.
  5. Make spiderweb topping: In a small bowl, stir together ¼ cup sour cream, 1 tablespoon sugar, and 1 teaspoon milk until smooth. Drizzle in 3-4 concentric circles over the cheesecake batter. Use a toothpick or skewer to drag lines from the center outward (like spokes), then drag lines from the edge back toward the center between each spoke to create a web pattern.
  6. Bake for 35-40 minutes. Edges should be set and slightly puffed, center should jiggle slightly. Turn off oven, crack door open, and let bars sit in cooling oven for 15 minutes. Transfer to a wire rack and cool completely at room temperature, about 1 hour.
  7. Cover pan with plastic wrap and refrigerate for at least 4 hours, preferably overnight.
  8. Lift bars out using parchment sling. Place on cutting board and slice into 16 squares with a sharp knife, wiping clean between cuts.

Notes

For best results, use full-fat cream cheese and let all ingredients come to room temperature. Black cocoa powder is essential for the deep color and flavor; regular cocoa won’t work as well. Chill overnight for cleanest slices. The spiderweb pattern may fade slightly after baking but will still look impressive. For a gluten-free version, use gluten-free chocolate graham crackers.
