Ingredients You’ll Need for S’mores Cookie Bars
- 1/2 cup Butter (softened, salted or unsalted)
- 1/3 cup Brown sugar
- 1/4 cup Granulated sugar
- 1 Egg
- 1 tsp Vanilla extract
- 1 & 1/2 cups All-Purpose flour
- 1/2 cup Graham crackers (finely crushed, about 3.5 sheets, for the cookie dough)
- 1/4 tsp Salt
- 3/4 tsp Baking soda
- 5 standard Hershey bars
- 1 & 1/2 cups Marshmallow fluff
Let’s Make It Together
- Preheat the oven to 350F. Line an 8×8 inch baking pan with parchment paper and set it aside.
- In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until combined and fluffy.
- Add in the egg and vanilla extract, mixing until everything is nice and smooth.
- Gradually add in the all-purpose flour, crushed graham crackers, salt, and baking soda. Mix until just combined, being careful not to overmix.
- Press half of the cookie dough evenly into the prepared baking pan. Once done, remove that layer and place it in the freezer to chill.
- Re-line the pan with fresh parchment paper, then press the remaining cookie dough into the pan as well.
- Place the Hershey chocolate bars over the dough. Feel free to break them apart to cover the entire surface.
- Spread the marshmallow fluff over the chocolate layer, ensuring it gets into all those nooks and crannies.
- Gently flip the chilled cookie dough layer on top of the marshmallow fluff, working carefully to keep it intact.
- Bake in the preheated oven for 25 minutes. Let the cookie bars cool completely before slicing into them to reveal that beautiful, melty cross-section.
Fun Ways to Customize It
- Nutty Twist: Add a handful of chopped nuts, like walnuts or pecans, for an enjoyable crunch.
- Candy Bar Remix: Substitute Hershey bars for your favorite chocolate bar—think Snickers or Reese’s for a decadent twist!
- Drizzled Decadence: Once cooled, drizzle melted chocolate or caramel over the top for a rich finishing touch.
- Seasonal Flavors: Add a hint of pumpkin pie spice in the dough for an autumnal twist or sprinkle in crushed peppermint for a festive treat during the holidays.
Chef Emma’s Helpful Tips
- Make-Ahead Magic: You can prepare the cookie dough in advance! Just store it in the refrigerator for up to 2 days before baking.
- Ingredient Swaps: If you’re out of graham crackers, try using crushed vanilla wafers or shortbread cookies instead for a delightful flavor twist.
- Slicing Trick: For perfectly cut bars, use a sharp knife dipped in hot water and wiped dry for a clean slice.
- Storage Suggestions: Keep leftovers in an airtight container at room temperature for up to a week. Trust me, they won’t last that long!
