Rice Krispie Log Recipe: No-Bake Cheesecake-Style Indulgence

This no-bake Rice Krispie Log recipe delivers all the nostalgic crunch and creamy goodness of a classic dessert without requiring a single oven turn-on. 💛 The secret lies in balancing melted butter, marshmallows, and crispy cereal into a log that chills into a perfect, sliceable treat—like a cheesecake you can actually eat without guilt (well, minimal guilt).

I’ve perfected this version to stay together while still offering that signature marshmallow cream texture.

The beauty of this recipe is its simplicity: just three core ingredients—butter, marshmallows, and Rice Krispies—come together in a 10-minute prep that requires no baking skills.

The log is shaped in a loaf pan and chilled for 2 hours, creating a firm yet tender base that holds up to slicing. For extra indulgence, I recommend a chocolate glaze drizzle or crushed cookie topping, but the basic version is already irresistible.

What makes this log special is its versatility—it’s perfect for holiday gatherings, potlucks, or even a quick treat when you’re craving something sweet.

The no-bake method means no risk of burning or waiting for an oven, and the result is a dessert that’s easy to customize with flavors like peanut butter, fruit compote, or even a sprinkle of cinnamon for warmth.

Once chilled, this log stays fresh for 3-4 days in the fridge, making it ideal for meal prep or gifting. Serve it with a scoop of vanilla ice cream for the full indulgence, or enjoy it on its own for a nostalgic, crunchy-sweet bite. Let’s get started!

Ingredients for rice krispie log

Just three core ingredients transform into a creamy, crunchy no-bake log that's pure nostalgia.

The butter is non-negotiable here—full-fat, unsalted is essential for that signature marshmallow cream texture. Land O'Lakes or Plugrá are my go-tos for reliability, but any good-quality brand works. Marshmallows? Mini marshmallows give you that even, creamy texture without the big pockets of air—no one wants a surprise marshmallow bite. Rice Krispies should be original flavor; the vanilla or honey varieties add too much sweetness. Pro tip: if your butter isn't melting fast enough, microwave it in 20-second bursts instead of all at once.

No vanilla extract? Vanilla sugar or a pinch of ground vanilla bean works in a pinch, but pure extract is what gives this that classic flavor. For the chocolate glaze, Ghirardelli chips melt the smoothest—no clumps. Short on powdered sugar? Granulated sugar works at double the amount, but it won't be as glossy. The heavy cream is key for stability; whipped to soft peaks before folding it in keeps the log from being too dense. And if you're feeling fancy, a sprinkle of crushed peppermint candies on top adds a festive touch for holidays.

This log is a fridge staple—3-4 days is standard, but honestly, it disappears faster than that. For make-ahead prep, assemble it the night before and refrigerate uncovered to let flavors meld. Wrap tightly in plastic wrap before chilling to prevent drying. If you're gifting, slice it into individual portions and package with a drizzle of chocolate glaze. Leftovers? Microwave for 10 seconds to revive the crunch—just don't overdo it, or you'll turn it into mush.

Step-by-step instructions for no-bake cheesecake-style Rice Krispie log

Here's how to make this creamy, no-bake dessert that tastes like a cross between cheesecake and Rice Krispie treats.

In a large microwave-safe bowl, melt the 1 cup unsalted butter in 30-second intervals, stirring between each interval until completely smooth. I like to work in short bursts to prevent overheating. Once melted, add the 14 oz large marshmallows and stir until fully combined and glossy.

This step is crucial—you want the marshmallows to melt completely into the butter, creating that signature creamy base. If you see any unmelted bits, give it another 10-second microwave burst and stir again. The mixture should be smooth and slightly thick, like a warm caramel sauce.

Remove the bowl from the microwave and let it cool for 2 minutes—it'll be hot! Then stir in the 0.5 cup heavy whipping cream, 1 tsp vanilla extract, and 0.25 cup granulated sugar until fully incorporated. The mixture will thicken noticeably as it cools.

Here's where the magic happens: add the 0.5 tsp cinnamon (if using) and mix well. The cinnamon adds a warm, spiced note that elevates this from basic to next-level. If you're making the chocolate glaze, set aside 0.5 cup dark chocolate chips for later—we'll use the rest of the mixture for the log itself.

Grab a large spoon or silicone spatula and gently fold in the 6 cups rice krispies cereal. Work quickly but carefully—you want to distribute the cereal evenly without crushing it. The mixture should hold together when pressed, but still be pourable.

I press down gently on the mixture in the bowl to check consistency—it should feel like thick, wet sand that holds together when shaped. If it's too crumbly, add another tablespoon of milk to help bind it. The goal is a texture that's firm enough to shape but still pliable.

Line the 9x5-inch loaf pan with plastic wrap, leaving some overhang on the sides for easy removal. Spoon the mixture into the pan and press down firmly to compact it evenly. Use the back of a spoon to smooth the top and create straight sides.

Cover the pan tightly with the remaining plastic wrap and refrigerate for at least 4 hours or overnight. This chilling time is non-negotiable—it lets the log firm up so it holds its shape when sliced. The longer it chills, the cleaner the cuts will be when you're ready to serve.

While the log chills, prepare the chocolate glaze by melting the 0.5 cup dark chocolate chips with the 1 tbsp milk over a double boiler or in 20-second microwave bursts, stirring between each interval until smooth. Stir in the 0.25 cup powdered sugar until fully combined.

Let the glaze cool slightly until it's thick enough to coat the back of a spoon but still pourable. Once your log is fully chilled, carefully remove it from the pan using the plastic wrap overhang. Drizzle or spread the glaze over the top and sides, then let it set for 10 minutes before slicing.

Best sauces and condiments for this recipe

Classic Chocolate Glaze

This rich, glossy glaze is the perfect finishing touch—it adds a luxurious sheen and balances the sweetness of the marshmallow cream. I use Ghirardelli dark chocolate chips because they melt smoothly without clumping.

For extra shine, whisk in 1 tbsp milk and ¼ cup powdered sugar until silky. Drizzle over the chilled log and let set for 10 minutes before slicing. 🍫

Peanut Butter Swirl

For a nostalgic twist, fold ½ cup creamy peanut butter into the marshmallow mixture before adding the Rice Krispies. Spread half the cereal mixture in the pan, then swirl in the peanut butter with a knife, and top with the remaining cereal.

Chill as directed—each slice will have creamy peanut butter pockets. Pair with a drizzle of melted chocolate for extra decadence.

Caramel Drizzle

Store-bought caramel sauce makes this log feel like a restaurant dessert. Warm ½ cup caramel sauce (like Smucker's) in the microwave for 20 seconds, then drizzle over the top of the chilled log.

Let it set for 5 minutes before slicing. For a homemade version, melt ½ cup brown sugar with 2 tbsp butter and 2 tbsp heavy cream until smooth.

Strawberry Compote

Fresh strawberries transform this into a fruity, summery dessert. Simmer 1 cup diced strawberries, 1 tbsp sugar, and 1 tsp lemon juice for 5 minutes until thickened.
