I enjoy this recipe because it delivers a wonderful combination of textures. The cornflakes stay crispy while the marshmallow mixture holds everything together with a soft chewiness.
Another reason I like making these bars is how simple they are to prepare. I only need a few ingredients and minimal cooking, making them perfect when I want a quick homemade treat.
I also appreciate how the pistachio butter adds a unique nutty flavor that pairs beautifully with dark chocolate and the sweet marshmallow base.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1 bag (10–12 oz) marshmallows 4 tablespoons unsalted butter 1/2 cup creamy pistachio butter pinch of salt 1 teaspoon vanilla extract 6 cups cornflakes cereal 16 oz dark chocolate (70–72% cacao preferred) 2 tablespoons coconut oil flaky sea salt for topping
Directions
I begin by lining a 9×13-inch baking pan with parchment paper, leaving a bit of overhang so I can easily lift the bars out later.
In a large saucepan, I melt the butter over medium-low heat. Once the butter is melted, I add the marshmallows and stir constantly until they melt completely and become smooth.
Next, I stir in the pistachio butter, a pinch of salt, and the vanilla extract. I mix everything together until the mixture is fully combined and creamy.
I remove the saucepan from the heat and gently fold in the cornflakes cereal. I stir carefully so the cereal becomes evenly coated without crushing the flakes too much.
Then I transfer the mixture into the prepared pan and gently press it into an even layer. I avoid packing it too tightly so the bars stay light and crunchy.
In a separate bowl, I melt the dark chocolate together with the coconut oil until smooth and glossy.
I pour the melted chocolate over the cornflake layer and spread it evenly across the surface.
While the chocolate is still soft, I sprinkle flaky sea salt generously over the top.
Finally, I place the pan in the refrigerator for about 30 to 45 minutes until the chocolate is fully set. Once firm, I lift the bars out using the parchment paper and slice them into squares before serving.
Servings and Timing
This recipe makes about 24 bars.
Prep time: 15 minutes Chill time: 30–45 minutes Total time: about 45 minutes
Variations
I sometimes replace pistachio butter with almond butter or peanut butter for a different nutty flavor.
For extra texture, I like adding chopped pistachios or roasted nuts to the cornflake mixture before pressing it into the pan.
Another variation I enjoy is drizzling white chocolate over the dark chocolate layer for a decorative finish.
If I want a slightly sweeter dessert, I occasionally use milk chocolate instead of dark chocolate.
Storage/Reheating
I store the bars in an airtight container in the refrigerator for up to 1 week.
If I prefer a softer texture, I let the bars sit at room temperature for a few minutes before serving.
For longer storage, I sometimes freeze the bars in a sealed container for up to 2 months and thaw them in the refrigerator before eating.
FAQs
Can I Use Store-Bought Pistachio Butter?
Yes, I often use store-bought pistachio butter for convenience, and it works perfectly in this recipe.
Why Should I Not Press The Mixture Too Firmly?
If I press the mixture too tightly, the bars can become dense. Pressing lightly keeps them crisp and chewy.
Can I Use Another Type Of Cereal?
Yes, I sometimes substitute rice cereal or another crispy cereal, though cornflakes provide the best crunch.
How Do I Melt Chocolate Smoothly?
I usually melt chocolate gently with coconut oil either in a microwave in short intervals or over a double boiler.
Can I Make These Bars Ahead Of Time?
Yes, I often prepare them a day in advance since they store well in the refrigerator.
