Looking for a perfect party dessert? This easy s'mores brownie recipe was made just for you!

I got the inspiration for this recipe from my birthday cake and rocky road brownies, and obviously was just thinking about how much I love s'mores 😋.

If you are wanting the perfect grown-up version of a classic summer dessert that honestly can be made even in the dead of winter (they're a year-round dessert in my eyes), these s'mores brownies are just waiting for you to make them!

why these are the best s'mores brownies

  • A grown-up and elevated mashup of three classic desserts: brownies, blondies, and s'mores!
  • The best crowd-pleasing party dessert
  • Easy to make from scratch
  • Fudgy, chewy, and layered with golden graham crackers, blondie batter, brownie batter, marshmallows, and lots of dark chocolate!

expert baking tips

  • Use a kitchen scale: Baking with a scale is faster, easier, and overall much more accurate than cup measurements.
  • Baking times may vary: All ovens are different, and your brownies may bake quicker or take longer than the indicated baking time. I recommend always checking on them occasionally and testing for doneness!
  • Don't overbake: These brownies are meant to be extra gooey like s'mores would be! The middle will be gooey but not raw when they are done baking.
  • Cut once cool: I know it's so hard to wait but they will literally fall apart if you cut them while they're warm! When you're ready, run a sharp knife under hot water and then grease it with nonstick spray, butter, or oil, to help cut through the marshmallows.

ingredient notes

ingredients needed to make this recipe.
  • Marshmallows: I used large marshmallows and then cut them into quarters (because I couldn't find any mini ones) but mini marshmallows work just as well!
  • Chocolate: You can use bar chocolate for both the batter and the top of the brownies. I typically use Ghiradelli chocolate.
  • Butter: Unsalted butter works best in this recipe!
  • Graham crackers: Any brand will work, you will have to break one in half to fit it in the pan.

recipe instructions

Before you start: Preheat your oven to 350 F/180 C. Spray or lightly butter the sides and bottom of an 8x8 baking pan then line it with parchment paper to cover all the sides.

Step 1: Lay the graham cracker sheets on the bottom of the prepared baking pan.

Step 2: Make the blondie batter by whisking together the brown sugar, white sugar, egg, egg yolk, and vanilla extract until light and fluffy. Stream the melted butter into the bowl whisking constantly until combined. Then fold in the all-purpose flour, salt, and baking powder until just combined.

Step 3: Pour half of the batter on top of the graham crackers, using an offset spatula to spread it evenly to fill the pan.

Step 4: Make the brownie batter by whisking together the sugar, egg, and vanilla until light and fluffy. Stream in the melted butter and chocolate, whisking constantly until well combined. Then fold in the all-purpose flour, cocoa powder, and salt until just combined.

Step 5: Pour the brownie batter into the pan, using an offset spatula to spread it to the edges.

Step 6: Evenly spread the rest of the blondie batter into the pan, then bake it for 30-33 minutes. You can test for doneness by inserting a toothpick into the center, it should come out covered in a few moist crumbs.

Step 7: Take the pan out of the oven and add the marshmallows and chopped dark chocolate. Return it to the oven and bake another 2-3 minutes or until the marshmallows look puffy.

storage

  • Room temperature: Once cooled, store them in a sealed container or in the pan covered in plastic wrap for 2-3 days.

faq's

Can they be made ahead of time?

Yes! These are best when they have ample time to cool completely before cutting otherwise they can be quite messy.

How do I cut them? When they are warm or cooled?

The best way to cut them is by running a sharp knife under very hot water, then greasing it with butter, oil, or nonstick spray. In between cuts, run the knife under hot water, wipe it clean, and re-oil it for really clean cuts!

Notes

PLEASE NOTE: I highly recommend using a kitchen scale to weigh your dry ingredients.
  • If you don't have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
