Easy S’mores Bars

The taste and flavor of s’mores are iconic and loved by many, so it’s no surprise that there are many different variations of this classic summer treat from S’mores Dip, an entire S’mores Board, to cocktails and everything in between. We love having the taste of S’mores in bar form, and we know you will too!

What makes this recipe unique is the use of biscoff cookies in the crust. Biscoff cookies are a Belgian dessert staple made with spiced Lotus flour. They have a distinct flavor that pairs perfectly with graham crackers. If you can’t find biscoff cookies, feel free to use any other type of cookie you like for the crust.

The recipe itself is simple and only requires a few ingredients that are probably already in your pantry. Simply mix the crust together, and press it into a baking pan. Bake and top with a rich mixture of chocolate, sugar, and marshmallows for a taste of summer any time of the year!

How To Make S’mores Bars

  1. Prepare for baking: Preheat the oven to 350°F, and line a 9×13-inch baking pan with parchment paper. Set aside.
  2. Assemble the crust: Process the cookies and crackers in a food processor until the texture of sand is achieved. To a large bowl, add the graham cracker crumbs, Biscoff cookie crumbs, butter, brown sugar and granulated sugar. Stir to combine fully.
  3. Bake the crust: Add the crust to the bottom of the prepared baking pan and press in with your fingers making sure it is evenly distributed. Bake in preheated oven for 10 minutes or until the crust begins to darken.
  4. Add the chocolate and marshmallows: Remove the crust from the oven, then spread the chocolate chips on top in an even layer. Return to the oven for 8 minutes then remove and spread the melted chocolate over top with a spoon into a smooth layer. Add the marshmallows to the top and bake for an additional 10-12 minutes.
  5. Set and serve: Let the s’mores bars cool for at least 30 minutes to set properly before slicing and serving.

Recipe Tips

  1. If you don’t have a food processor to break down the crackers and cookies, you can use a high-speed blender and pulse in batches.
  2. Make sure the crust is pressed down in an even layer before baking to ensure the ingredients are evenly distributed.
  3. Be careful not to overcook the chocolate chips or they can burn in the oven. Bake until just melted.
  4. To set quicker, let the s’mores bars cool for 15 minutes on the counter, then cover and place in the fridge to finish setting.


  • If you can’t find biscoff cookies, use additional graham crackers or any other type of shortbread cookie you like.
  • Add your favorite nuts, such as almonds or peanuts, to the crust for extra flavor and crunch.
  • Use a different type of chocolate chips, such as peanut butter or white chocolate chips to change up the flavor.
  • Add a teaspoon of vanilla extract to the chocolate and sugar mixture for a deeper flavor.
  • If you want gooey s’mores bars, try increasing the amount of marshmallows by up to an extra cup.
