Ingredient Additions and Substitutions
One of my favorite things about blondies is how easy they are to customize.
Chocolate: Use milk chocolate, dark chocolate, chocolate chunks, or a mixture of different chocolates.
Graham crackers: Digestive biscuits can work as a substitute if graham crackers aren't available.
Marshmallows: Mini marshmallows are easiest to distribute throughout the batter. Larger marshmallows can be chopped into smaller pieces.
Brown sugar: Light brown sugar works beautifully. Dark brown sugar creates a deeper molasses flavor.
Peanut butter: Add a few tablespoons of peanut butter to the batter or sprinkle peanut butter chips over the top.
Extra crunch: Add chopped pecans or walnuts for a little texture.
Chocolate topping: Sprinkle a handful of chocolate chips over the blondies during the final few minutes of baking.
How to Make S’mores Blondies
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). Line an 8-by-8-inch baking pan with parchment paper, leaving a little overhang on two sides.
This makes it much easier to lift the blondies out after they cool.
Step 2: Mix the Butter and Sugars
In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth.
Add the eggs and vanilla extract. Whisk until everything is well combined.
Step 3: Add the Dry Ingredients
Add the flour, baking powder, and salt. Stir gently with a spatula until just combined.
Be careful not to overmix. You want a thick, soft batter rather than a tough blondie.
Step 4: Fold in the S’mores Ingredients
Gently fold in the chocolate chips, graham cracker pieces, and mini marshmallows.
Reserve a small handful of each ingredient to sprinkle over the top if you want a pretty bakery-style finish.
Step 5: Fill the Baking Pan
Spread the batter evenly into your prepared pan.
The batter will be thick, so use a spatula to push it gently into the corners. Sprinkle the reserved chocolate chips, graham crackers, and marshmallows over the surface.
Step 6: Bake Until Golden
Bake for approximately 25–32 minutes, or until the edges are golden and the center is just set.
The center should look slightly soft, but it shouldn't be liquid. Avoid overbaking if you want that wonderful chewy texture.
If the marshmallows on top brown quickly, loosely cover the pan with foil toward the end of baking.
Step 7: Cool and Slice
Remove the pan from the oven and place it on a wire rack.
Allow the blondies to cool completely before lifting them out and slicing into squares. For cleaner cuts, wipe your knife between slices.
And there you have it! Delicious homemade S’mores Blondies ready to enjoy.
What to Serve with S’mores Blondies
These bars are delicious on their own, but a few simple additions make them feel extra special.
Vanilla ice cream: A scoop on a slightly warm blondie is hard to beat.
Cold milk: The perfect classic pairing.
Hot chocolate: Makes a cozy dessert for chilly evenings.
Coffee: The slight bitterness of coffee balances the sweetness.
Fresh strawberries: Add a little freshness alongside the rich chocolate.
Chocolate sauce: Drizzle a little over the top for an extra-decadent dessert.
For a party, arrange the blondies on a platter and sprinkle a few extra graham cracker crumbs around them. They look lovely!
Tips for the Best S’mores Blondies
A few little tricks will help you get the best results.
Measure the flour carefully. Too much flour can make blondies dry. Spoon it into your measuring cup and level it off rather than packing it down.
Don't overmix. Stir just until the flour disappears.
Use parchment paper. It makes removing and slicing the blondies much easier.
Reserve toppings. A few chocolate chips and marshmallows on top make the bars look extra inviting.
Watch the marshmallows. They can brown quickly, so keep an eye on the pan near the end of baking.
Let them cool. Warm blondies are delicious, but cooling helps them hold their shape.
Don't overbake. A slightly soft center is the secret to chewy blondies.
Storage Instructions
At room temperature: Store completely cooled blondies in an airtight container for up to 3 days. Keep them in a cool, dry place.
In the refrigerator: You can refrigerate them in an airtight container for up to 5 days. Allow them to come closer to room temperature before serving for a softer texture.
In the freezer: Wrap individual squares tightly and place them in a freezer-safe container or bag. Freeze for up to 2 months for best quality.
To reheat: Warm an individual blondie in the microwave for about 10–15 seconds. This softens the chocolate and marshmallows beautifully.
Frequently Asked Questions
Can I make S’mores Blondies ahead of time?
Absolutely! Bake them a day ahead, let them cool completely, and store them in an airtight container. They are a great make-ahead dessert for parties and gatherings.
Can I use large marshmallows instead of mini marshmallows?
Yes. Cut large marshmallows into smaller pieces before folding them into the batter. Keep in mind that marshmallows can become sticky and melt during baking.
Why are my blondies dry?
The most common reasons are adding too much flour or baking them too long. Measure carefully and start checking for doneness at around 25 minutes.
How do I know when blondies are done?
The edges should look golden and set, while the center should be just set and slightly soft. A toothpick inserted into the center may have a few moist crumbs, but it shouldn't have wet batter.
Can I make these blondies without graham crackers?
Yes! You can use digestive biscuits or another lightly sweet, crisp cookie. The flavor will be a little different, but they'll still be delicious.
Can I double the recipe?
Yes. Double the ingredients and use a 9-by-13-inch baking pan. The baking time may need to increase, so begin checking around 28–30 minutes and continue as needed.
Can I use a gluten-free flour blend?
A measure-for-measure gluten-free baking blend may work. Also make sure your graham crackers or substitute biscuits are gluten-free.
Can I make these without chocolate chips?
Of course! Use chopped chocolate, chocolate chunks, or even broken pieces of a chocolate bar.
