Ingredients You’ll Need
- ½ cup (113g) unsalted butter, softened: This creates a rich base for your blondies. Make sure it’s at room temperature for easy mixing.
- 2 cups (400g) packed brown sugar: Brown sugar adds moisture and that distinctive caramel flavor that every good blondie needs.
- 2 large eggs: Eggs help bind the ingredients and provide that lovely chewy structure.
- 1 teaspoon vanilla extract: Vanilla enhances the overall flavor profile, bringing warmth to the dish.
- ½ teaspoon salt: A touch of salt balances the sweetness and elevates all the flavors.
- 1 teaspoon baking powder: This gives your blondies lift, making them nice and fluffy.
- 2 cups (248g) all-purpose flour: The flour is the backbone of the blondies; it provides texture.
- 1 (13-ounce) jar Nutella or other chocolate spread: This is the magical layer that makes these blondies taste like s’mores. Feel free to swap out with a different chocolate spread.
- 8 ounces mini marshmallows: These will toast beautifully on top, providing that signature s’mores flavor.
How to Make S’mores Blondies
-
Preheat the Oven: Start by preheating your oven to 350°F. Line a 9×13” metal pan with foil, making sure to leave some overhang for easy removal later. Don’t forget to spray it well with cooking spray!
-
Mix the Butter and Brown Sugar: In a bowl, combine the softened butter and brown sugar, using a stand or hand mixer until the mixture is crumbly. This step is essential to create that sugary, buttery base.
-
Add Eggs and Vanilla: Next, mix in the eggs and vanilla extract until the mixture is smooth. This not only integrates the ingredients but also infuses your batter with that lovely vanilla essence.
-
Incorporate the Dry Ingredients: Stir in the salt, baking powder, and flour. The dough will be wet and slightly sticky, ensuring your blondies stay chewy once baked.
-
Spread the Batter: Spread the batter into the prepared pan. It can be tricky because it’s wet—using cooking spray on your hands can help smooth it out evenly.
-
Bake Perfectly: Bake for approximately 22-25 minutes. You’re looking for a light golden edge. Keep an eye on them; underbaked is preferred, as they’ll firm up while cooling.
-
Cool and Frost: Let the blondies cool completely in the pan. Once cooled, spread a generous layer of Nutella on top.
-
Top with Marshmallows: Scatter the mini marshmallows over your frosted blondies. Broil on high for about 1-2 minutes. Stay close to your oven; marshmallows can go from perfect to burnt in seconds!
Remember, the marshmallows are best enjoyed the same day to keep that gooey texture.
Storing & Reheating
To store your blondies, keep them in an airtight container at room temperature for about 2-3 days. If you want them to last longer, refrigerate them for up to a week in a sealed container. For longer storage, these blondies freeze beautifully, too! Wrap them tightly in plastic wrap and foil; they can last up to 3 months in the freezer. When you’re ready to indulge again, simply warm them in the microwave for about 15-20 seconds to revive that gooey goodness.
Chef’s Helpful Tips
- Ensure your butter is softened but not melted to maintain texture.
- Avoid overmixing your batter after adding the flour, as this can lead to a denser blondie.
- If you want even more chocolate, add chocolate chips to the batter before baking.
- Keep an eye on your marshmallows while broiling to avoid burning them.
- Make them your own! Try adding nuts or crushed graham crackers for added texture.
S’mores blondies offer a taste of summer camp nostalgia, combining rich flavors with the fun of baking. They are quick, simple, and always a crowd-pleaser. I hope you give this recipe a try and discover your new favorite treat. Remember, there’s nothing like the joy of sharing a delicious dessert, especially one that brings back memories of good times!

Recipe FAQs
Can I use a different type of chocolate spread?
Absolutely! While Nutella is delicious, feel free to switch it out for any chocolate spread that you love—almond or peanut butter spreads are great alternatives that can add a unique flavor twist.
How do I know when my blondies are done baking?
To check for doneness, look for a light golden edge and a slightly firm center. You can also insert a toothpick; it should come out with a few moist crumbs. Keep in mind that they will continue to firm up as they cool.
Can I make these blondies ahead of time?
Yes! You can prepare the batter a day in advance and store it in the refrigerator. When you’re ready to bake, spread it in the prepared pan and pop it into the oven. Just be sure to let it come to room temperature first for even baking.
Can I freeze leftovers?
Certainly! These blondies freeze well. Just be sure to wrap them tightly in plastic wrap and then foil. When ready to enjoy, allow them to thaw at room temperature or warm them briefly in the microwave.
