Ingredients

For the Cake Base:

250g (2 cups) chocolate sandwich cookies (like Oreos), crushed
115g (1/2 cup) unsalted butter, melted
120g (1 cup) graham crackers, crushed
50g (1/2 cup) cocoa powder
100g (3/4 cup) all-purpose flour
5g (1 teaspoon) baking powder
2g (1/2 teaspoon) salt
3 large eggs
200g (1 cup) granulated sugar
120ml (1/2 cup) vegetable oil
2 teaspoons vanilla extract
120ml (1/2 cup) buttermilk or milk

For the Chocolate Marble Layer:

150g (5oz) dark chocolate, melted
100g (3.5oz) white chocolate, melted

For the Caramel Topping:

200g (1 cup) granulated sugar
60ml (1/4 cup) water
120ml (1/2 cup) heavy cream, at room temperature
60g (1/4 cup) unsalted butter
5g (1 teaspoon) salt
150g (1 cup) roasted peanuts (unsalted or lightly salted)

Instructions

Prepare the pan: Line the bottom and sides of a 9-inch (23cm) springform pan with parchment paper for easy removal later.
Create the cookie base: In a medium bowl, combine the crushed chocolate cookies with the melted butter until evenly moistened. Press firmly into the bottom of the prepared pan to form an even layer. Refrigerate while preparing the next components.
Mix the dry ingredients: In a bowl, whisk together the crushed graham crackers, cocoa powder, flour, baking powder, and salt until well combined.
Prepare the cake batter: In a large mixing bowl, beat the eggs and sugar until light and fluffy, about 3-4 minutes. Add the oil and vanilla extract, beating until incorporated. Gradually add the dry ingredients, alternating with the buttermilk or milk, mixing just until combined.
Create the marble effect: Divide the batter into two equal portions. Gently fold the melted dark chocolate into one portion and the melted white chocolate into the other until just streaked (do not overmix).
Layer the cake: Pour the dark chocolate batter over the cookie base. Drop spoonfuls of the white chocolate batter on top. Using a knife or skewer, gently swirl the batters together to create a marbled effect, being careful not to overmix.
Bake the cake: Preheat your oven to 350°F (175°C). Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow to cool completely in the pan.
Make the caramel: In a medium saucepan, combine the sugar and water, stirring just until the sugar is moistened. Cook over medium-high heat without stirring until the mixture turns amber, about 8-10 minutes. Remove from heat and carefully add the heavy cream (it will bubble vigorously). Once the bubbling subsides, stir in the butter and salt until smooth.
Add the peanuts: Set aside about 1/4 cup of peanuts for topping. Stir the remaining peanuts into the caramel sauce, allowing them to become fully coated.
Top the cake: Pour the warm caramel peanut mixture over the cooled cake, allowing it to drip down the sides slightly. Sprinkle the reserved peanuts around the edge for decoration.
Chill and set: Refrigerate the cake for at least 2 hours, or until the caramel is set.
Serve: For the best texture and flavor, remove the cake from the refrigerator about 20-30 minutes before serving to allow it to come to room temperature.

Cooking Tips and Tricks

Cookie choice matters: For the base, choose cookies with a pronounced chocolate flavor. Removing cream filling from sandwich cookies is optional – it can add extra sweetness and help bind the crust.
Temperature control for caramel: Use a heavy-bottomed pan to prevent hot spots and burning. The caramel should be an amber color – too light and it will taste weak, too dark and it will taste bitter.
Safety first with caramel: Have all ingredients measured and ready before starting the caramel. When adding the cream, pour slowly and stand back to avoid steam burns.
Perfect swirling technique: For the most attractive marble effect, don’t overdo the swirling. Five to six passes with a knife or skewer is usually sufficient.
Testing for doneness: The cake is ready when a toothpick inserted comes out with a few moist crumbs, not completely clean (which would indicate overbaking).
Caramel consistency: If your caramel becomes too thick to pour, gently rewarm it. If it’s too thin, allow it to cool slightly longer before pouring.
Clean slicing: Dip your knife in hot water and wipe dry between cuts for picture-perfect slices.
Storage temperatures: The cake should be stored in the refrigerator but tastes best when served at room temperature, allowing the caramel to soften slightly.

Variations and Substitutions

Nut variations: Substitute peanuts with pecans, walnuts, hazelnuts, or a mix of your favorite nuts. For a nut-free version, try using granola, toffee bits, or toasted coconut flakes.
Cookie options: Graham crackers can be replaced with digestive biscuits, vanilla wafers, or shortbread cookies for different flavor notes.
Dietary adaptations: For a gluten-free version, use gluten-free cookies and flour blend. For dairy-free, use plant-based butter, milk alternatives, and dairy-free chocolate.
Flavor enhancements: Add 1 teaspoon of espresso powder to the chocolate batter to intensify the chocolate flavor, or 1/2 teaspoon of cinnamon for warmth.
Alternative toppings: Try a chocolate ganache layer under the caramel, or substitute the caramel with dulce de leche or butterscotch sauce.
Boozy version: Add 2 tablespoons of bourbon, rum, or coffee liqueur to the caramel for an adult variation.
No-bake option: For a truly no-bake version, replace the cake layer with additional layers of cookie crumbs alternated with a no-bake cheesecake filling.
Mini cakes: Prepare in a muffin tin lined with paper liners for individual servings, reducing the baking time to about 15-18 minutes.

Common FAQs

Q: Can I make this cake in advance?

A: Yes! This cake actually improves with time as the flavors meld. You can make it up to 3 days ahead and keep refrigerated. The caramel topping helps keep the cake moist.

Q: Why did my caramel crystallize?

A: Crystallization usually occurs if sugar crystals remain on the sides of the pan or if you stir the caramel while it’s cooking. To prevent this, brush the sides of the pan with water using a pastry brush, and avoid stirring once the mixture begins to boil.

Q: Can I freeze this cake?

A: Yes, the cake can be frozen for up to 2 months. Thaw overnight in the refrigerator, then bring to room temperature before serving. The texture of the caramel may change slightly but will still be delicious.

Q: My caramel is too runny. How can I fix it?

A: If your caramel is too thin, it likely wasn’t cooked long enough. You can either return it to the heat for a few more minutes (before adding the peanuts), or refrigerate the cake longer to help set the caramel.

Q: Is there a way to make this without nuts for allergy concerns?

A: Absolutely! The peanuts can be omitted entirely, or replaced with seeds like pumpkin or sunflower for crunch, or with chocolate chips or toffee pieces if nut allergies are the only concern.
