No-Fuss Dessert Bar with All the Campfire Flavor
Oh, my dear friend, there is a very specific kind of magic that happens when the sweet, nostalgic aroma of toasted marshmallows, rich chocolate, and buttery graham crackers drifts through your kitchen on a quiet evening. It instantly transports me back to crackling summer campfires, cozy Southern family reunions, and the welcoming warmth of a farmhouse kitchen where a gooey, sliceable dessert bar was always the undisputed star of the table.
Living on my own at 73, I’ve learned that the best recipes are the ones that deliver maximum, soul-warming comfort with absolute minimal cleanup. I love the rich, campfire flavor of a good s’more, but I certainly don’t want to fuss with melting marshmallows over an open flame, dealing with sticky, messy fingers, or eating a dessert so heavy it leaves me feeling sluggish.
Enter these No-Fuss S’mores Blondies.
This recipe perfectly honors my mother-in-law’s golden rule for family gatherings: it relies on just a few humble, pantry-staple core ingredients, requires almost zero active effort, and is so highly enjoyed that the baking pan is scraped completely clean! It tastes like an artisanal, slow-crafted campfire classic, but it actually comes together in about 10 minutes of hands-on time.
Grab your favorite mug of tea, because we’re about to bake up a batch of pure, gooey nostalgia.

S’mores Blondies: A Gooey, Nostalgic Treat That Disappears Every Time
For the Blondie Base
Ingredient Amount Notes
Unsalted butter ½ cup (1 stick), melted
Brown sugar 1 cup, packed Adds a deep, caramel-like sweetness
Granulated sugar ¼ cup
Large egg 1
Vanilla extract 1 teaspoon
All-purpose flour 1 cup
Baking powder ½ teaspoon
Salt ¼ teaspoon
For the S’mores Topping
Ingredient Amount Notes
Chocolate chips 1 cup (about 6 oz) Semi-sweet or milk chocolate
Mini marshmallows 2 cups
Graham cracker crumbs ½ cup About 4 full crackers, crushed
Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch or 9×9-inch baking pan with butter or nonstick spray. Line the pan with parchment paper for easy removal.
2. Make the Blondie Batter
In a medium bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the egg and vanilla and mix well.
In a separate bowl, combine the flour, baking powder, and salt. Gradually stir the dry ingredients into the wet mixture until just combined. Be careful not to overmix.
3. Spread the Batter
Spread the batter evenly into the prepared baking pan. It will be thick, but it spreads easily with a spatula.
4. Add the S’mores Topping
Sprinkle the chocolate chips evenly over the batter. Top with the mini marshmallows and graham cracker crumbs, pressing them down gently.
5. Bake
Bake for 20–25 minutes, until the edges are golden and the marshmallows are puffed and lightly toasted. The center should be set but still soft.
6. Cool and Slice
Let the blondies cool completely in the pan before slicing. For clean, neat squares, refrigerate for 30 minutes before cutting.
Pro Tips for Perfect S’mores Blondies
Don’t overmix the batter. Overmixing can make the blondies dense and tough. Stir just until the flour disappears.
Use fresh marshmallows. Fresh marshmallows melt and toast beautifully. Stale ones can become dry and hard.
Toast the graham crackers. For extra flavor, toast the graham cracker crumbs in a dry skillet for a few minutes before sprinkling them on top.
Line your pan with parchment paper. This makes it much easier to lift the blondies out and slice them neatly.
Let them cool completely. Warm blondies are delicious but can be messy to cut. Cooling allows the chocolate to set and the bars to hold their shape.

Frequently Asked Questions
Can I use a different size pan?
A 9×13-inch pan will produce thinner blondies and may require a shorter baking time (about 15–18 minutes). Adjust accordingly.
How should I store these blondies?
Store in an airtight container at room temperature for up to 3 days. For longer storage, freeze for up to 3 months.
Can I double the recipe?
Absolutely! Double all ingredients and bake in a 9×13-inch pan. The baking time will be similar—check for doneness at around 25 minutes.
Why are my blondies dry?
Overbaking is the most common culprit. Start checking for doneness at the minimum baking time and look for a set center that is still slightly soft.
A Story from My Kitchen
I first made these S’mores Blondies for a neighborhood potluck, and they were the first dessert to disappear. People kept coming back to the table, asking, “Are there more of those?” They have since become a staple at my gatherings—simple, nostalgic, and absolutely irresistible.
There’s something about the combination of chocolate, marshmallow, and graham cracker that feels like summer, like childhood, like comfort.
