Ingredients You’ll Need

  • Graham Crackers: The foundation of our crust, providing that classic s’mores flavor and crunchy texture to contrast with the creamy ice cream.

  • Salt: Enhances all the flavors and balances the sweetness.
  • Cinnamon: Adds a warm spice note to the crust that complements the chocolate beautifully.
  • Butter: Binds the crust together and adds richness.

How to Make Peanut Butter S’mores Ice Cream Cake

Step 1: Prepare the Graham Cracker Crust

Start by lightly greasing a deep-dish 9-inch springform pan with nonstick spray. In a large bowl, combine graham cracker crumbs, sugar, salt, and cinnamon. Pour in the melted butter and mix until the crumbs are evenly moistened. Press this mixture firmly into the bottom of your pan and slightly up the sides, creating a sturdy base. Pop it in the freezer while you prepare the filling.

Step 2: Create the Peanut Butter Ice Cream Mixture

Let your chocolate ice cream soften just enough to be workable – you want it soft but not melting. In a large bowl, gently fold the peanut butter into the softened ice cream. The key here is to maintain visible peanut butter streaks throughout the mixture – don’t overmix! These peanut butter ribbons will create beautiful swirls in every slice.

Step 3: Assemble and Freeze

Spoon your peanut butter-chocolate ice cream mixture over the chilled graham cracker crust, spreading it evenly. Cover with plastic wrap, pressing it directly onto the surface of the ice cream to prevent ice crystals. Return to the freezer and let it firm up completely – at least 4 hours, but preferably overnight for the best texture and flavor development.

Step 4: Add the S’mores Topping

Just before serving, remove your cake from the freezer and carefully release it from the springform pan. Pile mini marshmallows in the center of the cake, creating a mountain of fluffy goodness. Use a kitchen torch to toast them to a golden brown, just like you would around a campfire. Warm your peanut butter in the microwave until it’s drizzle-able, then artfully drizzle both the peanut butter and chocolate syrup across the top of the cake.

Pro Tips for Making the Recipe

  • Temperature Matters: Don’t let your ice cream get too soft before mixing – just pliable enough to fold in the peanut butter without melting completely.
  • Crust Technique: Use the bottom of a measuring cup to firmly press the crust into the pan for an even, compact layer.
  • Freezing Strategy: Clear enough space in your freezer beforehand to ensure the cake sits flat while freezing.
  • Toasting Technique: When toasting the marshmallows, keep the torch moving to prevent burning and aim for that perfect golden color.

How to Serve

This Peanut Butter S’mores Ice Cream Cake makes for a stunning centerpiece dessert at any gathering. For the perfect presentation:

Serving Suggestions

Slice the cake with a knife warmed in hot water and wiped clean between cuts for clean, beautiful slices. Serve on chilled plates to slow melting.

Pairing Ideas

This rich dessert pairs wonderfully with a cup of strong coffee or espresso to balance the sweetness. For the kids, cold milk is the classic accompaniment.

Make Ahead and Storage

Storing Leftovers

Cover any leftover cake tightly with plastic wrap and return to the freezer. The cake will keep well for up to 1 week, though the marshmallow topping is best enjoyed fresh.

Freezing

The base cake (without marshmallow topping) can be frozen for up to 2 weeks. Wrap tightly in plastic wrap followed by aluminum foil to prevent freezer burn.

Serving from Frozen

Remove the cake from the freezer about 10 minutes before serving to allow it to soften slightly for easier slicing. Add the marshmallow topping just before serving for the best texture contrast.

FAQs

  1. Can I use a different type of ice cream for this recipe?

    Absolutely! While chocolate ice cream creates that classic s’mores flavor, vanilla works beautifully too, especially if you fold in some mini chocolate chips. Coffee ice cream adds an interesting mocha dimension that pairs wonderfully with the peanut butter.

  2. I don’t have a kitchen torch. Can I still make this dessert?

    Yes! If you don’t have a kitchen torch, you can briefly place the marshmallow-topped cake under the broiler for 30-60 seconds, watching very carefully to prevent burning. Just be quick, as you don’t want the ice cream to start melting!

  3. How far in advance can I make this dessert?

    You can prepare the base cake (crust and ice cream layer) up to 2 weeks in advance. Add the toasted marshmallow and drizzle toppings just before serving for the best texture and appearance.

  4. Can I use natural peanut butter in this recipe?

    I don’t recommend it. Natural peanut butter tends to separate and harden differently when frozen, which can affect both the texture and taste of your cake. Stick with conventional creamy peanut butter for the best results.

Final Thoughts

This Peanut Butter S’mores Ice Cream Cake brings together the best of summer desserts – the nostalgia of campfire s’mores, the cool refreshment of ice cream, and the irresistible combination of chocolate and peanut butter. With its make-ahead convenience and showstopping presentation, it’s bound to become your new go-to dessert for special occasions or whenever you need to satisfy your sweet tooth with something extraordinary.

Description

Peanut Butter S’mores Ice Cream Cake is a decadent no-bake dessert featuring layers of creamy chocolate ice cream swirled with rich peanut butter on a buttery graham cracker crust, topped with toasted mini marshmallows, a drizzle of peanut butter and chocolate syrup. Perfect for summer gatherings, this frozen cake combines classic s’mores flavors for an irresistible treat.


Ingredients

Units Scale

For the Graham Cracker Crust:

  • 2 cups graham cracker crumbs, finely crushed
  • 1/4 cup (50g) granulated sugar
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground cinnamon
  • 1/2 cup (113g) unsalted butter, melted

For the Peanut Butter Ice Cream Cake:

  • 3 pints quality chocolate ice cream, softened
  • 1 and 1/2 cups creamy peanut butter (not all-natural)

For the Topping:

  • 1 and 1/2 cups mini marshmallows
  • 1/4 cup creamy peanut butter
  • 1/4 cup store-bought chocolate syrup

Instructions

  1. Prepare the Pan: Lightly grease a deep-dish 9-inch springform pan with nonstick baking spray and set aside for later use.
  2. Make the Graham Cracker Crust: In a large bowl, mix together the graham cracker crumbs, granulated sugar, salt, and cinnamon. Pour in the melted butter and use a rubber spatula to incorporate everything until the mixture resembles wet sand. Firmly press the mixture into the bottom and slightly up the sides of the prepared pan to create a sturdy crust. Place the pan in the freezer to set.
  3. Mix the Ice Cream Layer: In another large bowl, gently combine the softened chocolate ice cream with 1 and 1/2 cups of creamy peanut butter. Stir just enough so there are still visible streaks of peanut butter throughout, adding delicious ribbons in every slice.
  4. Assemble and Freeze: Spoon the peanut butter-chocolate ice cream mixture evenly over the prepared graham cracker crust. Spread smooth, then return the pan to the freezer and freeze until very firm—at least 4 hours, preferably 6 to 8 hours for best results.
  5. Add the Topping: When ready to serve, remove the cake from the freezer. Pile the mini marshmallows in the center and toast using a kitchen torch for golden, melty flavor. Microwave 1/4 cup of peanut butter for about 30 seconds until smooth and drizzle over the cake, then drizzle with chocolate syrup in thin lines.
  6. Serve: Slice the frozen cake and serve immediately, enjoying every gooey, creamy, chocolatey bite.

Notes

  • Use high-quality chocolate ice cream for best flavor and texture.
  • Avoid using all-natural peanut butter as it may separate and affect consistency.
  • The cake should be well frozen before adding toppings and slicing for the cleanest presentation.
  • For a nut-free version, substitute peanut butter with sunflower seed butter and ensure all other ingredients are nut-free.
  • If you don’t have a kitchen torch, you can briefly broil the marshmallows in the oven, watching closely.
  • This recipe can be made ahead of time and kept frozen until serving.
