A 9×9 pan filled with layered no‑bake dessert, showing alternating stripes of chocolate pudding, peanut butter filling, and marshmallow cream topped with mini marshmallows and chocolate chips—an irresistible S’mores Lasagna Dessert, also described as Peanut Butter S'mores Cake, No Bake Chocolate Peanut Butter Lasagna, Reese’s Chocolate Peanut Butter Cup Lasagna, and even Peanut Butter Cookie Lasagna, perfect for No Bake Summer Desserts, S'mores, Baking Sweets, and Yummy Sweets.

Summer’s here, the sun is blazing, and the last thing you want is to turn on your oven. Enter the S’mores Lasagna Dessert: a ridiculously easy, ultra‑decadent layered treat you assemble in minutes and chill in the fridge. Think of it like tiramisu’s fun cousin, decked out in graham crackers, chocolate, marshmallows, and (yes!) peanut butter—because really, why choose between s’mores and peanut butter cups when you can have both?

What Makes This Dessert So Irresistible?

First off, no baking required. If you can spread, stack, and stir, you can nail this recipe. Each bite delivers a soft, melty graham cracker layer soaked just enough to be tender but still hold its shape. Then comes the rich chocolate‑peanut butter filling—imagine a No Bake Chocolate Peanut Butter Lasagna meets your favorite Reese’s Chocolate Peanut Butter Cup Lasagna, all rolled into one. Top it off with fluffy marshmallow cream and a sprinkle of mini chocolate chips, and you’ve got a slice of pure Americana.

Bold Tip: The longer you chill, the softer your grahams become—plan ahead if you want a “cake‑like” texture, or serve after just an hour for a bit more crunch.

Layers of Yummy Sweets

Graham Cracker Base: Start with crushed grahams (or for a spin, use your go‑to Peanut Butter Cookie Lasagna crust). Mix crumbs with melted butter and press into a 9×9 pan.
Chocolate‑Peanut Butter Filling: Whip together cream cheese, peanut butter, powdered sugar, and a splash of milk until smooth. Fold in melted chocolate (a nod to Peanut Butter S’mores Cake vibes), then spread over your crust.
Marshmallow Mousse: Gently fold marshmallow fluff into whipped cream for that signature s’mores goo. Dollop or pipe this layer over the chocolate‑peanut butter mixture.
Graham Cracker “Roof”: Scatter more graham crumbs or whole pieces on top for texture.
Final Garnish: Sprinkle mini chocolate chips and drizzle extra peanut butter or chocolate ganache if you’re feeling fancy.

Why “Lasagna”?

Just like its savory namesake, this dessert stacks multiple layers into a delectable cross‑section. Unlike traditional casseroles, however, it won’t trigger smoke alarms or heat up your kitchen. It’s all about that no‑fuss, No Bake Summer Desserts vibe.

Hosting Hacks & Serving Suggestions

Make‑Ahead Magic: Assemble up to 24 hours in advance. Cover tightly and chill; it holds beautifully for backyard barbecues or poolside parties.
Cutting Tips: Run a sharp knife under hot water, wipe clean, and slice—it’ll give you those neat, Instagram‑worthy squares.
Portion Control: For a casual get‑together, cut into small squares. Feeling indulgent? Go for generous rectangles paired with a dollop of ice cream.
Add Fresh Fruit: A handful of sliced strawberries or raspberries adds a pop of color and balances sweetness.

FAQs You Didn’t Know You Had

Q: Can I swap in Oreos or graham‑chocolate hybrids?
A: Absolutely. Feel free to experiment with a Peanut Butter Cookie Lasagna crust or sandwich cookie base. Go wild—this dessert thrives on creativity.

Q: What’s the best marshmallow layer?
A: Marshmallow fluff folded into whipped cream gives stable peaks. If you want extra decadence, stir in mini marshmallows—just don’t overbeat or you’ll deflate your fluff!

Q: Can I use a pan other than 9×9?
A: Sure! A 9×13 pan works too; just expect thinner layers and faster chilling time. Adjust your portions accordingly.
