Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Chocolate sandwich cookies, finely crushed (for the crust)
Unsalted butter, melted
Heavy cream
Sweetened condensed milk
Creamy peanut butter (unsweetened)
Pure vanilla extract
Semisweet chocolate chips
Light corn syrup (optional, for silkier ganache)
Sea salt, a pinch, divided

Directions

Prepare the crust. Combine crushed chocolate sandwich cookies and melted butter until the mixture resembles wet sand. Press firmly into the base of a 23 cm (9-inch) springform pan. Chill for 15 minutes.
Whip the cream. In a chilled bowl, whip the heavy cream to stiff peaks. Reserve.
Create the peanut-butter base. In a separate bowl, whisk sweetened condensed milk, peanut butter, vanilla extract, and a pinch of sea salt until smooth.
Fold and fill. Gently fold the whipped cream into the peanut-butter mixture in three additions, retaining as much air as possible. Pour over the chilled crust and smooth the top. Freeze for 30 minutes.
Make the ganache. Heat chocolate chips with 60 mL (¼ cup) heavy cream and corn syrup (if using) until melted. Stir until glossy; allow to cool to pourable yet thick consistency.
Swirl. Dollop spoonfuls of ganache over the semi-frozen surface. Drag a skewer or thin knife through both mixtures to create marbled swirls.
Final freeze. Cover tightly and freeze at least 4 hours, preferably overnight, until fully set.
Serve. Release the springform ring, garnish with additional chocolate shavings if desired, and slice with a knife warmed under hot water.

Servings and Timing

Yield: 12 slices
Active preparation: 30 minutes
Passive freezing: 4–6 hours (or overnight)
Total time: Approximately 4 ½–6 ½ hours including freezing

Variations

Salted-caramel twist: Replace half the peanut butter with thick salted caramel sauce and sprinkle coarse sea salt on top before freezing.
Cookie-butter version: Substitute peanut butter with cookie butter and use speculoos biscuits for the crust.
Mocha swirl: Infuse the ganache with 1 tsp instant espresso powder for a subtle coffee note.
Vegan option: Use plant-based whipping cream, sweetened condensed coconut milk, vegan chocolate chips, and a coconut-oil-based cookie crust.

Storage/Reheating

Storage: Wrap the cake tightly in plastic wrap and a second layer of aluminium foil. Store in the freezer for up to 2 weeks for optimal flavour and texture.
Serving from frozen: Let the cake stand at room temperature for 10 minutes to ease slicing.
Reheating: Ice-cream cakes are not reheated; avoid microwaving as it will melt unevenly. Instead, temper briefly as noted above for neat slices.

FAQs

How far in advance can I make this cake?

You may prepare it up to 2 weeks ahead if well-wrapped to prevent freezer burn.

Can I use natural peanut butter?

Natural peanut butter tends to separate and freeze grainy; a stabilized, creamy style ensures a smoother texture.

What if I do not own a springform pan?

A deep 23 cm (9-inch) cake tin lined with overhanging parchment works; use the parchment to lift the frozen cake out.

Is there a nut-free alternative?

Swap peanut butter for sunflower-seed butter and ensure your other ingredients are nut-free.

Can I replace heavy cream with half-and-half?

Half-and-half will not whip to stiff peaks; the structure and lightness of the cake depend on fully whipped heavy cream.

Why add corn syrup to the ganache?

A small amount inhibits crystallisation, producing a glossy, slice-friendly chocolate layer that remains supple when frozen.

How do I keep the crust from crumbling?

Compact the crust firmly and chill it before adding the filling. Avoid over-baking if you choose to briefly set it in the oven.

What is the best knife for slicing?

A long, thin-bladed knife warmed under hot running water provides the cleanest cuts through frozen layers.

Can I colour the swirls?

Yes, tint part of the ganache with oil-based food colouring suitable for chocolate to achieve decorative marbles.

How do I scale the recipe for a crowd?

Double all components and assemble in a 33 cm × 23 cm (13 × 9-inch) pan; increase freezing time by 2 hours.
