Recipe Ingredients

Mix-Ins: we’re using semi-sweet chocolate chips, mini marshmallows, and gluten-free honey graham crackers to create that classic s’mores taste we all love.

Chocolate Bar: I like to use semi-sweet chocolate for these bars, but dark chocolate or milk chocolate will also work if that’s what you prefer. 

Flour: to keep these bars gluten-free, I used a 1:1 gluten-free all-purpose flour for the base of the batter. I’ve linked the specific brand I use and love in the recipe card, below.

Baking Soda and Baking Powder: For the best results, make sure they’re both fresh! 

Salt: just a bit of regular kosher salt in the bars helps to enhance the rest of the ingredients. Then, I like to sprinkle flakey sea salt on top for that perfect finish.

Melted Butter: this adds the perfect richness and delicious flavor.

Sugar: a combination of granulated sugar and dark brown sugar sweetens the recipe while keeping the bars soft and moist. 

Eggs: we’re using one whole egg and one egg yolk to add structure to the recipe and create the ultimate fudgy cookie texture. Trust me on this!

Vanilla Extract: a must for extra depth of flavor and a subtle vanilla taste. 

Ingredient Swaps

1. Flour – I’ve tested these bars with both gluten free and all-purpose flour and both work well! If you don’t have a gluten intolerance or allergy, feel free to use regular all-purpose flour. 
2. Butter – If you need to keep this recipe gluten free feel free to sub the butter for a vegan butter instead. I haven’t tested it but you could likely also substitute coconut oil as well. Just know that using coconut oil will give the bars a slight coconut flavor.
3. Chocolate – Substitute the semi-sweet chocolate with milk chocolate, dark chocolate, or your favorite dairy-free variety to keep the bars dairy free.

How to Make S’mores Cookie Bars

Step One: Preheat your oven to 350 degrees. Then, line a square baking dish with parchment paper, and lightly grease it with cooking spray. 

Step Two: Add the chocolate chips, mini marshmallows, and chopped graham crackers to a mixing bowl, and toss to combine. 

Step Three: Add the flour, baking soda, baking powder, and salt to a second bowl, and whisk to combine. 

Step Four: In a third bowl, add the granulated sugar, dark brown sugar, melted butter, and vanilla. Beat the wet ingredients with a hand mixer until well combined. Next, add the egg and egg yolk to the mixture, and beat again. 

Step Five: Fold the flour mixture into the bowl of wet ingredients, and stir until well combined. Next, add the mix-ins, and fold to distribute them evenly throughout the dough. Top the dough with the chopped chocolate bar, mini marshmallows, and crushed graham cracker.

Step Six: Bake the s’mores bars for 20 to 25 minutes or until the edges are set and the marshmallows are golden brown on top.  It’s normal for the edges to be a bit bubbly and caramelized! Remove the bars from the oven, and top them with flaky sea salt. 

Step Seven: Let the bars cool in the pan for 10 to 15 minutes or until they have set. Then, slice them into 16 bars, and enjoy! 

How to Store 

Store: Cover the baking dish tightly with storage wrap, or transfer the bars to an airtight container. They will stay fresh on the counter for 2-3 days.

Freeze: Wrap each bar in plastic wrap, and transfer them to a sealable bag or freezer-safe container. Freeze for up to 3 months. Thaw in the fridge overnight, or let the s’mores bars soften at room temperature when you’re ready to eat.
