Note on Scheduling: This is a great recipe to make over the course of a few days. You can make the Funfetti cake one day and freeze it, make the cookie dough disc another day and freeze it, make the cheesecake one day and refrigerate it, and then make your chocolate pouring sauce and assemble on the day you’ll serve the dessert.
Prepare your Funfetti cake: Mix and bake in 9-inch round cake pans according to box instructions and set aside to cool. Make one of these a pretty thin layer of cake — this will be the one you use on your cheesecake (be careful; a thinner layer will bake for less time). The other layer is extra; I tore mine up and froze it for future cake balls. After cooling, freeze your cake layer — it’s easier to work with when frozen.
Prepare your cheesecake: To make the cheesecake crust, preheat the oven to 350 degrees F. Butter two mini or one full-sized cheesecake pan. Combine the cookie crumbs, melted butter and salt in a small bowl. Toss with a fork to moisten all of the crumbs. Press into a thin layer covering the bottom of your cheesecake pan(s).
In the bowl of an electric mixer fitted with the paddle attachment, beat the cream cheese and sugar on medium-high speed until well blended. Beat in the flour and cake mix. Add in the vanilla and beat until well incorporated, scraping down the sides of the bowl as needed. Beat in the eggs one at a time, scraping down the bowl between each addition. Pour the filling into your cheesecake pan(s), leaving room for a cake and cookie dough layer on top of your cheesecake.
Bake until the top is lightly browned, puffed and cracked at the edges, and the center moves only very slightly when the pan is lightly shaken (about 40 minutes for a full-sized cheesecake or 12-15 minutes for mini cheesecakes). Transfer to a wire cooling rack. Cool at room temperature for at least 30 minutes. Transfer to the refrigerator and let cool at least 1 hour, until completely chilled and set.
Make the cookie dough: In a medium bowl, cream together butter and sugar for 2-3 minutes until light, fluffy, and pale yellow. Mix in salt, flour, cake mix, sprinkles, and vanilla. Add water one tablespoon at a time, mixing after each, until you reach cookie dough consistency. If making a full-sized cheesecake, line a 9-inch cake pan with plastic wrap and spread cookie dough in a disc in the pan. Freeze it until firm, about 15 minutes. If making mini cheesecakes, just chill the cookie dough until you’re ready to assemble your cakes.
Make the chocolate pouring sauce: Heat chocolate and cream together in a bowl set over simmering water. Let them sit for a few minutes before whisking them together to combine. Whisk in powdered sugar and then add 1 tablespoon of water at a time, mixing after each until you reach pouring consistency. Set the sauce aside and let it cool to warm.
Assemble the cheesecakes: If you’re making mini cheesecakes, use a round cookie cutter or a serrated knife to cut circles of Funfetti cake to fit on each mini cheesecake. Spread a little chocolate sauce on the top of each mini cheesecake before placing a cake round on each and gently pressing them down snugly. If you’re making a full-sized cheesecake, spread chocolate sauce over your cheesecake and just place full frozen cake layer on top and gently press down.
If making mini cheesecakes, spread cookie dough into the top of each well with the back of a spoon. If making a full-sized cheesecake, spread another thin layer of chocolate sauce on top of the cake layer to act as glue, and then take your frozen cookie dough disc and place it on top. Chill cheesecake(s) for about 30 minutes before gently unmolding them. Drizzle with melted chocolate and top with a dollop of whipped cream, sprinkles, and a maraschino cherry.
