The recipe is time-consuming but not too tricky, if you’re up for a slightly more challenging recipe that yields incredible results, this one is worth it." —Cara Cormack

Preheat the oven to 350 F and prepare a 9” springform cake pan. Place the springform pan on top of two pieces of parchment paper and trace a 9” circle. Cut the circles out. Reserve one circle for the assembly portion of the recipe. Flip the other circle over so any remaining marks from the pen will be on the bottom. Grease the bottom and sides of the pan with cooking spray. Place the parchment circle in the bottom of the pan. Set aside.
