S’mores Blondies

How to Make S’mores Blondies

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line it with parchment paper, leaving a little overhang to make removing the blondies easier.

Step 2: Mix the Sugars and Butter

In a large mixing bowl, whisk together the melted butter, packed light brown sugar, and granulated sugar until the mixture is smooth and well combined.

Step 3: Add the Eggs and Vanilla

Whisk in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until everything is evenly combined.

Step 4: Combine the Dry Ingredients

In a separate bowl, mix the all-purpose flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture until just combined. Avoid overmixing to help keep the blondies soft and chewy.

Step 5: Add the Graham Crackers and Chocolate

Fold in 1 cup of the broken graham cracker pieces and 1 cup of the semisweet chocolate chips. Distribute them evenly throughout the batter so every bar has plenty of chocolate and graham cracker flavor.

Step 6: Bake the Blondies

Spread the batter evenly into the prepared pan. Bake for 18 minutes, allowing the blondies to begin setting before adding the toppings.

Step 7: Add the Marshmallows and Remaining Toppings

Carefully remove the pan from the oven. Sprinkle the mini marshmallows evenly over the top, followed by the remaining graham cracker pieces and chocolate chips.

Return the pan to the oven and bake for another 8–12 minutes, until the edges are set and the marshmallows are puffed and lightly golden.

Step 8: Cool and Slice

Let the blondies cool completely in the pan before cutting them into bars. This gives the center time to set and helps you achieve cleaner slices.

Tips for the Best S’mores Blondies

Line the pan with parchment paper. This makes it easier to lift the blondies out of the pan once they have cooled.

Do not overmix the batter. Fold in the dry ingredients just until combined to maintain a tender, chewy texture.

Watch the marshmallows closely. They can brown quickly, so keep an eye on the pan during the final baking stage.

Allow enough cooling time. Cutting the blondies while they are still warm can cause them to fall apart, especially with the melted chocolate and marshmallow topping.

Customize the chocolate. Semisweet chocolate chips provide a balanced sweetness, but you can use milk chocolate chips if you prefer a sweeter dessert.

How to Store S’mores Blondies

Store the cooled blondies in an airtight container at room temperature for up to 3 days. For the best texture, keep them in a single layer or separate layers with parchment paper to prevent the marshmallow topping from sticking.

If you prefer to make them ahead, allow the blondies to cool completely before storing them.

Frequently Asked Questions

Can I make S’mores Blondies ahead of time?

Yes. You can bake them a day ahead and store them in an airtight container at room temperature. Let them cool completely before slicing and storing.

How do I know when the blondies are done?

The edges should look set, and the marshmallows should be puffed and lightly golden. The center may still feel soft when hot, so allow the blondies to cool completely before cutting.

Can I use regular marshmallows instead of mini marshmallows?

Mini marshmallows are easiest to distribute evenly over the blondies. If you only have regular marshmallows, cut them into smaller pieces before adding them.

Why should I let the blondies cool completely?

Cooling helps the center firm up and allows the chocolate and marshmallow topping to settle. This makes the bars easier to slice without falling apart.
