Ingredients:

For the Graham Cracker Crust:
- 2 cups (about 14-16 full sheets) graham cracker crumbs (finely crushed)
- 1/2 cup (1 stick) unsalted butter, melted
- 1/4 cup granulated sugar
- 1/4 teaspoon ground cinnamon (optional, but I think it adds a lovely warmth!)
For the Vibrant Blueberry Filling:
- 4 cups fresh or frozen blueberries (if using frozen, do not thaw beforehand)
- 1/2 cup granulated sugar (adjust to your sweetness preference and the tartness of your berries)
- 2 tablespoons fresh lemon juice (key for brightening the flavor!)
- 1/4 teaspoon lemon zest (optional, for an extra zing)
- 3 tablespoons cornstarch
- 1/4 cup cold water
- 1 teaspoon vanilla extract (pure vanilla is always best!)
For the Dreamy Marshmallow Cream Topping:
- 8 ounces (1 block) cream cheese, softened to room temperature
- 1 cup powdered sugar (confectioners’ sugar), sifted
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon almond extract (optional, but a wonderful complement to blueberries!)
- 1 (7 ounce) jar marshmallow creme (like Fluff) OR 4 cups mini marshmallows, melted and slightly cooled
- 1 1/2 cups heavy cream (cold)
For Garnish (Optional, but highly recommended!):
- Fresh blueberries
- Fresh mint leaves
- A light dusting of powdered sugar

Preparing the Graham Cracker Crust

Prepare your baking dish: I always start by lightly greasing a 9×13 inch baking dish. A glass dish works beautifully for this because you can see all those lovely layers! If you prefer, you can line it with parchment paper, leaving an overhang on the sides, which makes lifting the entire “Blueberry Marshmallow Delight” out for clean slicing incredibly easy later on.
Crush the graham crackers: My favorite method is to place the graham cracker sheets into a large zip-top bag and crush them using a rolling pin until they resemble fine crumbs. You can also use a food processor for this; just pulse until fine, being careful not to over-process into a paste. We’re aiming for about 2 cups of fine crumbs.
Melt the butter: In a microwave-safe bowl, melt your 1/2 cup of unsalted butter. This usually takes about 30-45 seconds in the microwave, or you can do it gently on the stovetop.
Combine crust ingredients: In a medium bowl, combine the graham cracker crumbs, melted butter, 1/4 cup granulated sugar, and the optional 1/4 teaspoon ground cinnamon. Mix thoroughly with a fork or your hands until all the crumbs are moistened and resemble wet sand. This ensures a sturdy, flavorful crust for your “Blueberry Marshmallow Delight”.
Press the crust: Pour the crumb mixture into your prepared 9×13 inch baking dish. Using the bottom of a flat glass or a measuring cup, firmly press the mixture evenly into the bottom of the dish. The firmer you press, the less crumbly your crust will be when you serve. I like to make sure the edges are well-compacted too.
Chill the crust: Place the pressed crust into the refrigerator for at least 20-30 minutes while you prepare the other components. This chilling step helps the butter solidify and binds the crust together even more, making it less prone to breaking apart. You could also bake it for 8-10 minutes at 350°F (175°C) if you prefer a slightly crispier, more toasted crust, but for this “Blueberry Marshmallow Delight”, a no-bake crust works wonderfully.

Crafting the Vibrant Blueberry Filling

Combine blueberries and sugar: In a medium saucepan, combine the 4 cups of blueberries (fresh or frozen, unthawed), 1/2 cup granulated sugar, 2 tablespoons fresh lemon juice, and the optional 1/4 teaspoon lemon zest.
Cook the blueberries: Place the saucepan over medium heat. Stir occasionally. As the blueberries heat up, they will start to release their juices and break down. This process usually takes about 8-10 minutes. You’ll see the mixture bubble gently, and the berries will soften considerably. I absolutely love the aroma that fills my kitchen at this stage!
Prepare the cornstarch slurry: While the blueberries are cooking, in a small separate bowl, whisk together the 3 tablespoons of cornstarch and 1/4 cup of cold water until completely smooth and lump-free. This is your thickening agent!
Thicken the filling: Once the blueberries are soft and juicy, slowly pour the cornstarch slurry into the bubbling blueberry mixture in the saucepan, whisking constantly. Continue to cook and stir for another 1-2 minutes, allowing the mixture to come to a gentle boil and thicken significantly. It should coat the back of a spoon. You want it thick enough to hold its shape, but still spreadable.
Add vanilla and cool: Remove the saucepan from the heat. Stir in the 1 teaspoon of vanilla extract. Pour the hot blueberry filling into a clean bowl and allow it to cool completely to room temperature. This is a crucial step! If you try to spread warm blueberry filling over your chilled crust, it can make the crust soggy. You can speed up the cooling process by placing the bowl in an ice bath or chilling it in the refrigerator for about 30-45 minutes, stirring occasionally, until it’s no longer warm to the touch. This step ensures the layers of your “Blueberry Marshmallow Delight” remain distinct and beautiful.

Creating the Dreamy Marshmallow Cream Topping

Soften cream cheese: Make sure your 8 ounces of cream cheese are at room temperature. This is absolutely essential for a smooth, lump-free topping. If it’s too cold, you’ll end up with lumps, and nobody wants that in their creamy topping! You can soften it by leaving it on the counter for about an hour, or by microwaving it in its wrapper for 15-20 seconds on low power.
Whip the cream cheese mixture: In a large mixing bowl, using an electric mixer (either a stand mixer with the paddle attachment or a hand mixer), beat the softened cream cheese on medium speed until it’s light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl.
Add powdered sugar and extracts: Gradually add the 1 cup of sifted powdered sugar to the cream cheese, beating on low speed until just combined, then increase to medium until fully incorporated and smooth. Mix in the 1 teaspoon pure vanilla extract and the optional 1/4 teaspoon almond extract. Beat until everything is well combined and creamy.
Incorporate marshmallow: Here’s where the “Marshmallow” in “Blueberry Marshmallow Delight” really comes to life! Gently fold in the 1 (7 ounce) jar of marshmallow creme. If you’re using mini marshmallows, melt 4 cups of them in a microwave-safe bowl (microwave in 15-second intervals, stirring after each, until smooth) and allow them to cool slightly before folding them into the cream cheese mixture. Be gentle here; we want to keep some air in the mixture. Mix just until combined. The mixture will be thick and sticky.
Whip the heavy cream: In a separate, very cold bowl (I like to chill my bowl and beaters in the freezer for 10-15 minutes), pour in the 1 1/2 cups of cold heavy cream. Using your electric mixer, beat the heavy cream on high speed until stiff peaks form. This means when you lift the beaters, the cream will stand up firmly without flopping over. Be careful not to overbeat, or you’ll end up with butter!
Fold everything together: Gently, but thoroughly, fold the whipped cream into the cream cheese and marshmallow mixture. Use a rubber spatula and a “cut and fold” motion to incorporate the whipped cream without deflating it too much. You want to maintain that light, airy texture. Keep folding until no streaks of whipped cream remain and the mixture is uniformly light and fluffy. This topping is truly a dream and makes the “Blueberry Marshmallow Delight” incredibly indulgent!

Assembling Your Blueberry Marshmallow Delight

Retrieve the chilled crust: Take your graham cracker crust out of the refrigerator. It should be firm and ready for its first layer.
Layer the blueberry filling: Spoon the completely cooled blueberry filling evenly over the chilled graham cracker crust. Gently spread it right to the edges using an offset spatula or the back of a spoon. Make sure it’s an even layer, as this will be the stunning blue center of your “Blueberry Marshmallow Delight”.
Add the marshmallow topping: Carefully spoon the dreamy marshmallow cream topping over the blueberry layer. Again, use an offset spatula or the back of a spoon to gently spread it evenly all the way to the edges, creating a beautiful, smooth white cloud on top. Try not to press down too hard, as you don’t want to mix the layers. I love how the vibrant blue contrasts with the pristine white!
Smooth the top: For a picture-perfect finish, gently smooth the marshmallow topping with your spatula. You can even create some soft swirls or peaks if you’re feeling artistic.

Chilling and Serving Your Delight

The waiting game (chilling!): This is the hardest part, but possibly the most important step for the “Blueberry Marshmallow Delight”! Cover the baking dish tightly with plastic wrap and refrigerate for at least 4-6 hours, or preferably overnight. This chilling time allows all the layers to set firmly, the flavors to meld beautifully, and ensures clean, distinct slices. Rushing this step will result in a messy, unset dessert, so trust me, patience is a virtue here!
Garnish (the final flourish): Before serving, remove the plastic wrap. If you wish to garnish, sprinkle with fresh blueberries and tuck in a few vibrant fresh mint leaves for a pop of color and freshness. A light dusting of powdered sugar can also add a touch of elegance.
Slice and serve: Using a sharp knife that has been run under hot water and wiped clean between each cut (this helps prevent sticking and creates clean slices), cut your “Blueberry Marshmallow Delight” into squares. Serve immediately and watch your guests’ eyes light up! This dessert is best enjoyed chilled.

Tips for the Perfect Blueberry Marshmallow Delight

Room Temperature Cream Cheese is Non-Negotiable: I cannot stress this enough. If your cream cheese is cold, your topping will be lumpy, no matter how long you beat it. Plan ahead!
Cool the Blueberry Filling Completely: Just like with the cream cheese, temperature matters. Spreading warm blueberry filling over the cold crust or under the marshmallow topping will cause issues. It can soften the crust or make the top layer melt and weep, ruining the beautiful layers of your “Blueberry Marshmallow Delight”. Give it ample time to cool to room temperature, or even chill it in the fridge for a bit.
Don’t Overmix Whipped Cream: Keep a close eye on your heavy cream when whipping it. It goes from perfectly stiff peaks to over-beaten (and eventually butter) very quickly. Stop as soon as it holds its shape.
Sifting Powdered Sugar: While not always critical, sifting powdered sugar for the marshmallow topping helps ensure a super smooth, lump-free texture.
For a No-Mess Cut: Dip your knife in hot water and wipe it clean between each slice. This creates those perfect, clean lines that make your “Blueberry Marshmallow Delight” look professional and incredibly appealing.
Adjust Sweetness: Taste your blueberry filling before you thicken it. If your blueberries are particularly tart, you might want to add another tablespoon or two of sugar. Everyone’s sweetness preference is different!
Make Ahead: This “Blueberry Marshmallow Delight” is an excellent make-ahead dessert! In fact, it tastes even better the next day after all the flavors have had time to fully develop and meld. It will keep well in the refrigerator, covered, for up to 3-4 days.

Variations to Try

Mixed Berry Delight: Instead of just blueberries, try a mix of strawberries, raspberries, and blueberries for the fruit layer. The combination of colors and flavors would be absolutely stunning in this “Blueberry Marshmallow Delight”. You might need to adjust the sugar slightly depending on the tartness of your chosen berries.
Lemon Zest Explosion: Amp up the lemon! Add a teaspoon of lemon zest to the crust mixture for an extra bright, zesty base. You could also increase the lemon zest in the blueberry filling for an even more pronounced citrus note.
Cookie Crust: Swap out the graham crackers for other crushed cookies. Oreos (minus the cream filling), Nilla Wafers, or even shortbread cookies would make a fantastic alternative crust, each offering a unique flavor profile to your “Blueberry Marshmallow Delight”. If using Oreos, you might want to reduce the added sugar in the crust as the cookies are already quite sweet.
Nutty Crunch: For an added texture and flavor, mix 1/2 cup of finely chopped pecans or walnuts into your graham cracker crust mixture. This provides a lovely crunch that complements the creamy layers beautifully.
Tropical Twist: For a fun twist, consider adding a layer of thinly sliced fresh mango or pineapple (well-drained of excess juice) over the blueberry layer, or even mix it into the blueberry filling. This would give your “Blueberry Marshmallow Delight” a wonderfully refreshing, tropical vibe.
Dark Chocolate Drizzle: A light drizzle of melted dark chocolate over the top of the set marshmallow layer before serving would add a touch of sophistication and a delicious flavor contrast.
Espresso Boost: For coffee lovers, dissolve 1 teaspoon of instant espresso powder in the melted butter for the crust. This subtle coffee note can beautifully enhance the other flavors without being overwhelming.

Frequently Asked Questions (FAQs)

Can I use frozen blueberries for this recipe?

Absolutely! Frozen blueberries work wonderfully in this recipe. There’s no need to thaw them beforehand; just toss them into the mixture straight from the freezer. You might find that the baking time increases by a few minutes, as the frozen berries will release more moisture and cool down the batter, but the end result will still be just as delicious and bursting with flavor.

How long does Blueberry Marshmallow Delight last, and how should I store it?

When properly stored, your delightful creation will stay fresh for about 2-3 days at room temperature in an airtight container. If you want to extend its life, you can refrigerate it for up to 5 days. Just make sure it’s well-sealed to prevent it from drying out or absorbing other odors from the fridge. I personally love it slightly warmed, even on the second or third day!

Can I make this recipe ahead of time?

Yes, this is a fantastic make-ahead dessert! You can prepare the entire dish, bake it, let it cool completely, and then store it as mentioned above. If serving to guests, you might want to gently warm it in a low oven (around 250°F or 120°C) for 10-15 minutes before serving to bring out its wonderful gooey texture again. Alternatively, you can assemble the mixture and refrigerate it unbaked for up to 24 hours, then bake it fresh when you’re ready to serve.

What kind of marshmallows are best for this recipe?

For the best results, I recommend using standard mini marshmallows. Their smaller size ensures they melt evenly and create that beautiful, gooey topping without becoming overly dense. While larger marshmallows can work, you might need to cut them into smaller pieces to ensure consistent melting throughout the dessert.

Can I make this a gluten-free or dairy-free dessert?

Adapting this recipe for dietary needs is certainly possible! For a gluten-free version, simply substitute the regular flour with a good quality 1:1 gluten-free baking flour blend. Make sure your gluten-free blend contains xanthan gum, or add about half a teaspoon per cup of flour. For a dairy-free version, you would need to use plant-based milk and a dairy-free butter alternative. There are many excellent dairy-free marshmallows available on the market now as well, so be sure to check those labels!
