There are some desserts that instantly take you back to childhood, and S’mores Blondies are one of those magical treats for me.

Instead of waiting for warmer days, I decided to transform those beloved flavors into a rich, chewy blondie that could be baked any time of year. The result was even better than I imagined: buttery blondies loaded with melty chocolate, gooey marshmallows, and crunchy graham crackers in every single bite.

Now these blondies have become one of those desserts my family requests for birthdays, movie nights, potlucks, and holiday gatherings. They’re simple enough for a weekday baking session but impressive enough to bring to parties. Best of all, they capture everything people love about traditional s’mores without needing a campfire.

Ingredient Notes & Details

• Unsalted Butter
  Butter creates the rich, caramel-like flavor that makes blondies so irresistible. Using unsalted butter allows you to control the overall salt level while giving the bars their signature chewy texture.
• Brown Sugar
  Dark or light brown sugar both work wonderfully. Brown sugar adds moisture, sweetness, and that delicious caramel note that pairs perfectly with chocolate and marshmallows.
• Large Eggs
  Eggs provide structure while keeping the blondies soft and tender. Let them come to room temperature for smoother mixing.
• Vanilla Extract
  A generous splash of vanilla enhances every flavor in the recipe and gives the blondies a warm bakery-style aroma.
• All-Purpose Flour
  Regular all-purpose flour creates the ideal chewy crumb. Be careful not to overmeasure, as too much flour can make blondies dry.
• Baking Powder
  A small amount provides just enough lift without making the bars cakey.
• Salt
  Salt balances the sweetness while making the chocolate and caramel flavors stand out even more.
• Milk Chocolate Bars
  Classic milk chocolate delivers authentic s’mores flavor. You can substitute chocolate chunks or chocolate chips if that’s what you have available.
• Mini Marshmallows
  Mini marshmallows melt evenly across the surface and become beautifully gooey during baking.
• Graham Crackers
  Crushed graham crackers add crunch and unmistakable s’mores flavor. Save a few larger pieces for topping to create a bakery-worthy appearance.
• Chocolate Chips (Optional)
  Adding extra chocolate chips creates pockets of melted chocolate throughout every bite.

Step-by-Step Instructions

1. Prepare your baking pan
   Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on the sides for easy removal. Lightly grease the parchment for extra insurance against sticking.
2. Melt the butter
   Melt the butter until completely smooth. Allow it to cool for about 5 minutes so it doesn’t scramble the eggs when mixed together.
3. Mix the wet ingredients
   Whisk the melted butter with the brown sugar until glossy and smooth. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract until fully incorporated. The mixture should appear silky and slightly thick.
4. Combine the dry ingredients
   In a separate bowl, whisk together the flour, baking powder, and salt. This helps distribute the leavening evenly throughout the batter.
5. Make the blondie batter
   Gradually fold the dry ingredients into the wet ingredients using a spatula. Mix only until no streaks of flour remain. Avoid overmixing, which can lead to dense blondies instead of perfectly chewy ones.
6. Add the chocolate
   Fold in most of the chopped milk chocolate and chocolate chips, reserving a handful for topping. The batter should be thick but easy to spread.
7. Spread into the pan
   Transfer the batter to the prepared pan and spread it evenly with an offset spatula or the back of a spoon. Press a few extra chocolate pieces into the surface.
8. Begin baking
   Bake for about 22–25 minutes. The edges should look lightly golden while the center remains slightly underbaked.
9. Add marshmallows and graham crackers
   Remove the pan from the oven and quickly scatter the mini marshmallows and graham cracker pieces across the top. Return the pan to the oven for another 5–8 minutes. Watch carefully during this stage. The marshmallows should puff and become lightly golden without burning.
10. Cool completely
    Allow the blondies to cool in the pan for at least one hour. This cooling time helps the bars set properly, making them much easier to slice neatly.
11. Slice and serve
    Lift the blondies out using the parchment paper. Use a sharp knife to cut into squares, wiping the blade clean between cuts for beautiful bakery-style slices. Serve slightly warm if you love extra gooey chocolate and marshmallows.

FAQ for Common Questions

• What are S’mores Blondies?
  S’mores Blondies are chewy dessert bars made with buttery blondie batter and topped with classic s’mores ingredients including chocolate, marshmallows, and graham crackers.
• Can I make easy S’mores Blondies ahead of time?
  Absolutely. These blondies actually taste even better the next day as the flavors continue to develop and the texture becomes even chewier.
• Why are my blondies dry?
  The most common causes are overbaking or adding too much flour. Measure carefully and remove the blondies when the center still looks slightly soft.
• Can I use chocolate chips instead of chocolate bars?
  Yes. Chocolate chips work perfectly, although chopped chocolate bars create larger pools of melted chocolate throughout the blondies.
• How do I keep the marshmallows from burning?
  Add them during the last few minutes of baking instead of placing them on top from the beginning. Keep a close eye on the oven once the marshmallows are added.
• Can I double this recipe?
  Yes. Double the ingredients and bake in two separate pans for the most even results rather than using one oversized pan.

Storage Tips

• Refrigeration
  Store leftover S’mores Blondies in an airtight container for up to 5 days. Separate layers with parchment paper to prevent sticking.
• Freezing
  Wrap individual blondie squares tightly in plastic wrap before placing them into a freezer-safe container or freezer bag. Freeze for up to 3 months. Thaw overnight in the refrigerator or at room temperature before serving.
• Reheating
  Microwave individual blondies for 10–15 seconds to soften the marshmallows and melt the chocolate again. Always discard blondies that develop mold, unusual odors, or have been left at room temperature for more than two days in very warm environments.
