1-First Step: Make the Crust: Preheat your oven to 350°F and grab a 9×13 inch metal pan. Spray the bottom, line it with parchment paper, and spray again to prevent sticking. Grind 3 cups of chocolate sandwich cookies into fine crumbs using a food processor or a sealed bag and a rolling pin. In a bowl, mix the crumbs with 2 tablespoons of granulated sugar and 1/2 cup of melted unsalted butter until it’s all moistened. Press this firmly into the pan and bake for 12 minutes. Let it cool completely on a wire rack before moving on this sets the base for your Oreo Caramel Cake.

2-Second Step: Make the Cake Batter: Lower the oven temperature to 325°F now that the crust is done. In a large bowl, whisk together 3 cups of cake flour, 1 tablespoon of baking powder, and 1 teaspoon of salt this dry mix is key for the structure. In a stand mixer, cream 1 cup of room temperature unsalted butter, 1 3/4 cups of granulated sugar, and 2 tablespoons of vegetable oil until it’s fluffy and light. Add in 3 large eggs and 3 large egg whites one at a time, beating well after each. Then, mix in 1/3 cup of sour cream and 1 tablespoon of pure vanilla extract for that extra flavor. On low speed, alternate adding the flour mixture and 1 1/4 cups of buttermilk, starting and ending with flour. Gently fold in 6 coarsely crushed chocolate sandwich cookies. For a dairy-free twist, swap buttermilk with almond milk here. Pour the batter over the cooled crust and bake for 40-43 minutes, or until a toothpick comes out with just a few moist crumbs. Let it cool completely in the pan to keep it moist.

3-Third Step: Make the Caramel Sauce: Now for the caramel it’s easier than you think! In a medium saucepan, combine 1 cup of granulated sugar, 1/4 cup of water, and 3 tablespoons of light corn syrup. Bring it to a boil over medium heat without stirring to avoid crystals. Let it cook until it turns a golden brown color, which takes about 8-10 minutes. While that’s happening, warm 3/4 cup of heavy cream in the microwave for 20-30 seconds. Once the sugar is golden, slowly stir in the warm cream it might bubble up, so be careful. Remove from heat and add 2 teaspoons of pure vanilla extract, 1 teaspoon of salt, and 3 tablespoons of butter, stirring until smooth. If you’re watching calories, use a low-fat cream alternative for this step. Let the sauce cool a bit before using.

4-Fourth Step: Make the Chocolate Cookie Buttercream: Time to frost! In a stand mixer, cream 1 1/2 cups of slightly cold unsalted butter until it’s smooth and creamy. Add 6 cups of sifted powdered sugar, 3 tablespoons of heavy whipping cream, 1 teaspoon of vanilla extract, and a pinch of salt. Beat on medium speed until the mixture is light and fluffy, about 2-3 minutes. Gently fold in 6 chocolate sandwich cookies ground into fine crumbs for that Oreo punch. If you want it vegan, substitute with a plant-based butter and cream. This frosting is versatile and can be adjusted for taste add more cream if it’s too thick.

5-Fifth Step: Assemble the Cake: Once everything is cooled, frost the top of your cake with the chocolate cookie buttercream. Add dollops of the caramel sauce and swirl it in for that marble effect it’s so pretty! Sprinkle some crushed chocolate sandwich cookies on top for extra crunch. Slice and serve at room temperature for the best flavor. This step is where you can get creative, like adapting for gluten-free needs by using safe cookies. Your Oreo Caramel Cake is ready to enjoy, and it serves 12-16 people easily!
