S'more Blondie Ingredients
- Dark Brown Sugar: This is a must-have ingredient for its rich, deep sweetness that adds a caramel-like flavor to the blondies. It also helps to keep the texture moist and chewy, making each bite incredibly satisfying.
- Graham Crackers: Crushed graham crackers are essential for giving the blondies their classic s'more taste. I like using cinnamon flavored. They infuse the dough with that familiar toasty flavor. My graham cracker crust lemon bars are amazing.
- Cinnamon: A hint of extra cinnamon in the graham cracker cookie dough adds a warm, cozy flavor that perfectly complements the graham crackers. This subtle spice elevates the overall taste, giving the blondies an extra layer of deliciousness.
- Dark Chocolate: Dark chocolate is needed to balance the sweetness of the blondies. Its rich, slightly bitter taste cuts through the sweetness of the sugar and marshmallow, creating a perfect harmony of flavors. Check out my sweet and salty cookies too!
- Marshmallow Fluff: The key to blondies with marshmallows is instead of regular marshmallows, marshmallow fluff is used to achieve a smooth, gooey filling that mixes perfectly with the other ingredients. Regular marshmallows can become too chewy and lose their texture, almost disappearing, while marshmallow fluff stays creamy and gooey, ensuring every bite has that classic gooeyness.
- Extra egg yolk: I always add an extra egg yolk to my blondie recipes, it makes the final result way more fudge like and tender. Check out my brownies with cream cheese frosting!

Smore Blondie Variations
- Add apeanut butter twist to your blondies by swirling creamy peanut butter into the batter before baking. The rich, nutty flavor pairs perfectly with the chocolate and marshmallow, creating a decadent treat. You can also sprinkle some crushed peanut butter cups on top for extra indulgence.
- Elevate your s mores blondies with a touch of salted caramel. Drizzle caramel sauce over the batter and sprinkle with a pinch of sea salt before baking. The caramel adds a buttery sweetness, while the sea salt enhances the flavors, balancing the sweetness and adding a gourmet touch.
- Top the blondies with vanilla ice cream or the ultimate summer dessert!!

S'more Blondie Pro tips
- Use Room Temperature Ingredients: Ensure that your butter, eggs, and other refrigerated ingredients are at room temperature before mixing. This helps the ingredients blend more smoothly and evenly, resulting in a more consistent and tender blondie texture.
- Don’t Overmix the Batter: When combining the wet and dry ingredients, mix just until they are incorporated. Overmixing can cause the blondies to become tough and lose their desired chewy texture. Gentle mixing will keep the blondies soft and chewy.
- Properly Layer the Marshmallow Fluff: To achieve the perfect gooey consistency, layer the marshmallow fluff evenly between the blondie batter layers. This prevents it from sinking to the bottom and ensures you get that gooey, marshmallow goodness in every bite. Using a spoon dipped in warm water can help spread the fluff more easily and evenly.
Smore Blondies FAQs
What does a blondie taste like?
Unlike brownies, which are typically chocolate-based, blondies are made with vanilla and brown sugar, giving them a rich, caramel-like flavor. They are often described as the "blonde" version of brownies due to their lighter color
Can I use white sugar instead of brown sugar in these smore blondies?
No you can't, the texture will be very off and dry. Dark brown sugar has more molasses in it resulting in a chewy texture and more moisture.
What is marshmallow fluff?
Marshmallow fluff, also known simply as "fluff," is a light and fluffy marshmallow-based spread. It is made from sugar syrup, corn syrup, egg whites, and vanilla. The ingredients are whipped together to create a smooth and creamy texture that resembles melted marshmallows.
How to store S'more Blondies
Room Temperature
Allow the blondies to cool completely, then transfer them to an airtight container or sealable bag. They can be kept at room temperature for up to 3-4 days.
Freezer
First, ensure they're completely cooled at room temperature. Then place them in an airtight container or freezer-safe bag. Label the container with the date and contents before placing it in the freezer. When you're ready to enjoy them, simply thaw the blondies at room temperature for a few hours or overnight
