How to Make Gluten-Free S’mores Bars
Ingredients
- 1/2 cup (4 oz/8 Tablespoons) Butter, softened
- 3/4 cup (150 grams) brown sugar
- 1 egg, room temperature
- 1 teaspoon vanilla extract
- 1 cup (120 grams) gluten-free measure-for-measure flour
- 1 cup (120 grams) gluten-free graham cracker crumbs*
- 1/2 teaspoon baking powder
- 1/4 teaspoon kosher salt
- 1 (7 oz.) container marshmallow fluff or marshmallow creme (do not substitute marshmallows)
- 1 cup semi-sweet chocolate chips or chopped chocolate bars
Step by Step
- Start by preheating the oven to 350 degrees F. Line an 8×8 metal pan with parchment paper or foil. (Parchment paper prevents scratching the pan.)
- In a large mixing bowl or the bowl of a stand mixer, combine softened butter and brown sugar. Cream for 2-3 minutes, or until smooth and fluffy.
- Add the egg and vanilla extract to the butter/sugar mixture, mixing until fully combined.
- Scrape down the bowl and add the gluten-free flour, graham cracker crumbs, baking powder, and salt. Mix until just combined, ensuring no dry patches remain.
- Take roughly 2/3 of the graham cracker dough and spread it evenly into the prepared pan. Since the dough is sticky, an offset spatula works best for smoothing it out.
- Layer the marshmallow fluff over the cookie dough, spreading it evenly.
- Sprinkle the chocolate chips or chopped chocolate over the marshmallow layer evenly.
- With the remaining 1/3 of the graham cracker dough, take small dollops and pat them out in your hand. Spread these pieces over the marshmallows and chocolate, allowing some marshmallow to peek through.
- Bake for 25-30 minutes, or until the top is just set and starting to turn golden. The bars may appear jiggly due to the gooey marshmallow layer.
- Let the s’mores bars cool completely before slicing into bars. For cleaner cuts, refrigerate them first, as they’ll cut much easier when cold.

How to Serve Gluten-Free S’mores Bars

How to Store Gluten-Free S’mores Bars
