Why You’ll Love This Recipe

There’s so much to love about these No Bake S'mores Cheesecake Bars! First off, they come together quickly—just 20 minutes of prep time and no baking required. The creamy marshmallow cheesecake filling is rich and smooth, balanced by the crunch of the graham cracker crust. The milk chocolate ganache and toasted marshmallow topping add the perfect finishing touches for that iconic s’mores experience. Whether you’re hosting a summer party or simply want a delicious treat, these bars are the perfect solution. Plus, they can be made ahead and chilled, so you don’t have to spend much time in the kitchen.

Ingredients

For the Graham Cracker Crust:

  • 1 ½ cups graham cracker crumbs

  • ¼ cup granulated sugar

  • 8 tablespoon unsalted butter, melted

For the Marshmallow Cheesecake:

  • 24 oz cream cheese, softened

  • 2 tablespoon heavy whipping cream

  • 2 cups miniature marshmallows

  • 1 teaspoon vanilla extract

  • ½ cup powdered sugar

For the Milk Chocolate Ganache:

  • 9.3 oz milk chocolate bars (6 - 1.55 oz bars)

  • ⅓ cup heavy whipping cream

For the Topping:

  • 2 cups miniature marshmallows

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

  1. Graham Cracker Crust:
    Spray a 9-inch baking pan with cooking spray and line it with parchment paper. In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter. Stir with a fork until the butter is fully incorporated. Press the mixture evenly onto the bottom of the prepared pan to form the crust. Refrigerate the crust for at least 30 minutes to set.

  2. Marshmallow Cheesecake:
    Beat the softened cream cheese on medium-high speed for 2 to 3 minutes until it is light and fluffy. Add the heavy whipping cream and beat for another 2 minutes. In a separate bowl, microwave the miniature marshmallows on high for 30 seconds, then stir until fully melted. Stir the vanilla extract into the melted marshmallows. Add the marshmallow mixture to the cream cheese mixture and beat until well combined and smooth. Add the powdered sugar and continue beating until incorporated. Pour the cheesecake filling over the chilled crust, spreading it evenly. Cover with plastic wrap and refrigerate for at least 4 hours, or until the cheesecake is firm.

  3. Milk Chocolate Ganache:
    Break the milk chocolate bars into pieces and place them in a heatproof bowl. Heat the heavy whipping cream in a small saucepan until it is scalding hot, then pour it over the chocolate. Let it sit for 3 minutes to soften, then stir until smooth and glossy. Pour the ganache evenly over the chilled cheesecake layer. Return to the refrigerator and let it chill for at least 30 minutes.

  4. Topping:
    Just before serving, top the cheesecake with the miniature marshmallows. Place the bars under a broiler for about 30 seconds or until the marshmallows turn golden brown. Alternatively, you can use a kitchen torch to toast them or leave them as is. Slice into bars and serve.

Variations

  • Chocolate Options: For a twist, try using dark chocolate or white chocolate instead of milk chocolate for the ganache.

Storage/Reheating

FAQs

1. Can I make these cheesecake bars ahead of time?

Yes! These No Bake S'mores Cheesecake Bars need at least 4 hours of chilling time, making them perfect to prepare the day before you plan to serve them.

2. Can I substitute the graham cracker crust with something else?

Yes, you can substitute the graham cracker crust with other types of cookies, such as Oreos or digestive biscuits, for a different flavor.

3. Can I use regular marshmallows instead of miniature marshmallows?

Yes, you can use regular marshmallows, but you will need to cut them into smaller pieces before using them in the cheesecake filling and topping.

4. Do I need to use a springform pan for this recipe?

No, a standard 9-inch square or rectangular pan works perfectly fine for this recipe.

5. Can I use store-bought graham cracker crumbs?

Absolutely! Store-bought graham cracker crumbs save time and effort if you want to skip the step of crushing your own graham crackers.

6. How long do the cheesecake bars need to chill?

The cheesecake filling needs to chill for at least 4 hours to firm up, and the ganache should chill for an additional 30 minutes.

7. Can I make this recipe without the ganache?

Yes, you can skip the ganache if you prefer, but it adds a delicious chocolate layer that complements the other ingredients perfectly.

8. How can I toast the marshmallows without a broiler?

You can use a kitchen torch to toast the marshmallows, or simply leave them as they are if you prefer a non-toasted topping.

9. Can I make these bars gluten-free?

Yes! To make these bars gluten-free, use gluten-free graham crackers or another gluten-free cookie base for the crust.

10. Can I use a different type of cream cheese?

While traditional cream cheese works best for the cheesecake filling, you can try a flavored cream cheese, such as marshmallow or vanilla cream cheese, for an extra twist.

Conclusion

No Bake S'mores Cheesecake Bars are the perfect dessert to enjoy during the warmer months, bringing all the nostalgic flavors of s'mores without the need for a campfire. With a smooth marshmallow cheesecake filling, a crunchy graham cracker crust, and a decadent milk chocolate ganache, these bars are a treat everyone will love. Plus, they’re easy to make and can be prepared in advance, making them an excellent choice for any gathering or just a sweet treat at home.
