Step‑by‑Step Instructions for Gooey S’Mores Bars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While it warms, line a 9×13 inch baking pan with foil, leaving some overhang for easy removal later. Lightly spray the foil with non-stick spray to ensure your Gooey S’Mores Bars come out effortlessly after baking.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together 1 1/2 cups of all-purpose flour, 1 1/2 cups of graham cracker crumbs, 1 teaspoon of baking powder, and 1/2 teaspoon of salt. This step is essential for the structure and flavor of your bars. Look for a uniform mixture to guarantee even baking once combined with the wet ingredients.
Step 3: Cream the Butter and Sugar
In another bowl, use an electric mixer to cream together 1 cup of unsalted butter with 1 cup of light brown sugar on medium speed. Mix for about 2 minutes until the mixture is light and fluffy. The air whipped into the butter will create a tender, chewy texture in your S’Mores Bars.
Step 4: Incorporate the Eggs
Add 2 eggs to the butter and sugar mixture, mixing until just combined. This should take about 30 seconds with your mixer. Ensure no streaks of egg remain, as they help bind all the ingredients for a cohesive dough, adding moisture and richness to your dessert.
Step 5: Combine Wet and Dry Ingredients
Gradually mix the dry ingredients into the wet ingredients until a soft dough forms. Use a spatula to scrape down the sides as necessary to ensure all components are evenly incorporated. The dough will be thick and slightly sticky, perfect for creating the base layer for your Gooey S’Mores Bars.
Step 6: Press the Base Into the Pan
Taking half of the dough, press it evenly into the prepared baking pan to form a solid, compact base. Use your fingers or a spatula to smooth the surface down. This layer will hold all the delicious chocolate and marshmallow topping, so ensure it’s well-packed and level for even baking.
Step 7: Layer the Marshmallow and Chocolate
Spread a generous layer of marshmallow topping, or marshmallow crème, over the crust, making sure to cover it all the way to the edges. Then, sprinkle 1 cup of milk chocolate chips evenly across the marshmallow layer. This combination mimics the classic s’mores experience everyone loves.
Step 8: Crumble Remaining Dough on Top
Crumble the remaining dough over the chocolate chips and marshmallow topping. Make sure to allow some of the toppings to peek through, as this will create a beautiful texture and enhance the gooeyness of your S’Mores Bars once baked. Aim for an even coverage but don’t worry about perfection here!
Step 9: Bake to Golden Perfection
Place the pan in the preheated oven and bake for 30 to 35 minutes. Look for a golden brown top and a slightly firm center that is just set. The edges should begin to pull away from the sides of the pan, indicating the delicious bars are ready to come out.
Step 10: Cool and Cut
Once baked, remove the pan from the oven and let the bars cool completely on a wire rack. This cooling process is crucial for clean, even slices. Allow at least an hour before cutting into squares, ensuring your Gooey S’Mores Bars hold their shape and texture for that perfect bite.

Storage Tips for S’Mores Bars
Room Temperature: Store your S’Mores Bars in an airtight container at room temperature for up to 1 week. This helps maintain their chewy texture and delicious flavors.
Refrigerator: For longer freshness, you can refrigerate the bars for up to 2 weeks. Just ensure they’re well-wrapped to prevent them from drying out.
Freezer: To extend the life of your S’Mores Bars, freeze them in an airtight container for up to 3 months. When ready to enjoy, thaw them in the refrigerator overnight and bring them to room temperature before serving.
Reheating: If you prefer them warm, microwave individual bars for about 10-15 seconds. This will soften the chocolate and marshmallow, creating that gooey delight that’s so irresistible!

Make Ahead Options
These Gooey S’Mores Bars are perfect for meal prep enthusiasts! You can prepare the base and marshmallow layer up to 24 hours in advance, allowing you to simply assemble and bake when ready. To do this, prepare the dough and spread it into the pan, but hold off on the marshmallow topping and chocolate chips. Cover the unbaked crust tightly with plastic wrap and refrigerate. When you’re ready to bake, spread the marshmallow crème and sprinkle the chocolate chips, then bake according to the instructions. This ensures the bars stay just as delicious and gooey without compromising taste or texture, giving you more time to enjoy with family and friends!
Expert Tips for S’Mores Bars
- Cool Before Cutting: Allow the bars to cool completely before cutting to avoid messy slices and maintain their delightful structure.
- Sticky Marshmallow Topping: Use wet hands to spread the marshmallow topping smoothly over the crust, making this sticky process easier.
- Bake Time Check: Keep an eye on the baking time; ovens may vary. The bars should be golden brown with a slightly firm center when done.
- Avoid Overmixing: When combining wet and dry ingredients, mix until just combined. Overmixing may lead to tough bars instead of the desired chewy texture.
- Packaging for Freshness: Store leftovers in an airtight container at room temperature for freshness, ensuring your S’Mores Bars stay moist and delicious!
- Customize Your Bars: Feel free to experiment with different chocolate types or add nuts to create a unique flavor profile tailored to your taste.

S’Mores Bars Recipe FAQs
How do I know if my marshmallows are ripe?
Absolutely! Look for marshmallows that are white and fluffy with no dark spots or hard textures. Fresh marshmallows should feel soft and springy. If you spot any dark spots all over, it may be time to toss them!
What is the best way to store S’Mores Bars?
Store your S’Mores Bars in an airtight container at room temperature for up to one week to keep them chewy and delicious. For extra freshness, you can refrigerate them for up to two weeks. Just make sure they’re well-wrapped to avoid drying out!
Can I freeze S’Mores Bars?
Yes, you can! To freeze your S’Mores Bars, wrap them individually in plastic wrap and then place them in an airtight container. They’ll stay fresh for up to three months. When ready to enjoy, thaw them overnight in the refrigerator, then bring to room temperature and pop them in the microwave for 10-15 seconds for a warm treat!
What should I do if my S’Mores Bars are too crumbly?
Very! If your bars turned out crumbly, it may be due to overbaking or not enough moisture in the dough. Make sure to follow the baking time carefully and check for a slightly firm center. If your dough feels dry at the start, consider adding a splash more of melted butter or an extra egg to add moisture during mixing.
Are S’Mores Bars safe for dogs or people with allergies?
I recommend avoiding feeding S’Mores Bars to your furry friends, as chocolate and certain ingredients can be toxic to dogs. For allergies, it’s essential to know any specific dietary restrictions or food allergies concerning ingredients like eggs, gluten, or any nuts you might add as toppings. Always feel free to adapt the recipe to meet those needs!
