Everything You Need To Make This Recipe Without Stress

Gathering your ingredients before you start baking is a simple step that makes the whole process smoother and more enjoyable. You’ll find most of these items are pantry staples, ensuring you can whip up a batch of these delightful cookies whenever the craving strikes. The beauty of this recipe lies in its simplicity and the readily available nature of its components.

INGREDIENTS:

1/2 cup (1 stick) unsalted butter, softened
1/2 cup granulated sugar
1/4 cup packed light brown sugar
1 large egg
1 teaspoon vanilla extract
1/2 cup unfed sourdough discard (at 100% hydration)
1 1/2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 cup semi-sweet chocolate chips or chunks
1 cup mini marshmallows
1/2 cup graham cracker crumbs (about 4-5 full graham cracker sheets, crushed)
Extra mini marshmallows and graham cracker pieces for topping (optional)

For simple substitutions, you can easily swap semi-sweet chocolate chips for milk chocolate or dark chocolate chips, depending on your preference. If you don’t have mini marshmallows, you can cut larger marshmallows into smaller pieces with kitchen shears. When it comes to graham crackers, any brand will do; just make sure they are crushed into fine crumbs for the best texture in the cookie dough, and slightly larger pieces for topping if desired. Using unsalted butter allows you to control the salt content in the recipe, but if you only have salted butter, omit the added salt in the recipe.

How To Make It Step By Step With Visual Cues

Creating these chewy, gooey sourdough s’mores cookies is a straightforward process. Follow these steps for perfect results every time.

Prepare Your Oven and Baking Sheets: Preheat your oven to 375°F (190°C). Line two large baking sheets with parchment paper or silicone baking mats. This prevents sticking and makes for easy cleanup.
Cream Butter and Sugars: In a large mixing bowl, using an electric mixer, cream together the softened butter, granulated sugar, and light brown sugar until the mixture is light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl as needed to ensure everything is well combined.
Add Wet Ingredients: Beat in the egg and vanilla extract until fully incorporated. Then, add the sourdough discard and mix until just combined. The mixture might look a little curdled at this point, but don’t worry, it will come together.
Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures the leavening and seasoning are evenly distributed throughout the dough.
Mix Wet and Dry: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; stop as soon as no streaks of flour remain. Overmixing can lead to tough cookies.
Fold in S’mores Goodness: Gently fold in the chocolate chips, mini marshmallows, and graham cracker crumbs by hand using a spatula. Distribute them evenly throughout the dough.
Scoop and Bake: Drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between each cookie. If desired, lightly press a few extra mini marshmallows and small graham cracker pieces onto the top of each cookie before baking for an extra s’mores look. Bake for 10-12 minutes, or until the edges are lightly golden and the centers are still slightly soft. The marshmallows will be puffed and lightly toasted.
Cool and Enjoy: Remove the cookies from the oven and let them cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This allows them to set up properly and prevents them from breaking.

Easy Variations And Serving Ideas That Fit Real Life

These sourdough s’mores cookies are fantastic as is, but a few simple tweaks can make them even more exciting or tailored to different occasions.

Chocolate Choices: Experiment with different types of chocolate! White chocolate chips or even chopped peanut butter cups could add another layer of flavor. For a richer cookie, use dark chocolate chunks.
Nutty Addition: If no one has allergies, a handful of chopped pecans or walnuts could add a lovely texture and flavor contrast.
Spiced S’mores: A pinch of cinnamon or a dash of nutmeg in the dry ingredients can give these cookies a warm, spiced note, especially nice during cooler months.
Kid-Friendly Fun: Let kids help crush the graham crackers (in a zip-top bag with a rolling pin!) or press extra toppings onto the scooped dough. It’s a great way to get them involved.
Party Platter Perfect: Arrange these cookies on a platter with other desserts for a dessert bar. They’re visually appealing and always a crowd-pleaser.
Ice Cream Sandwich: For an extra special treat, sandwich a scoop of vanilla ice cream between two cooled cookies.
Dipping Delight: Serve warm cookies alongside a small bowl of chocolate fudge sauce or caramel for dipping.
Mini Cookie Bites: For smaller portions or a party, use a mini cookie scoop to make bite-sized cookies. Adjust baking time down slightly.

Common Slip-Ups And How To Avoid Them

Even with a simple recipe, a few common mistakes can impact the final outcome. Here’s how to ensure your sourdough s’mores cookies turn out perfectly every time.

Overmixing the Dough: This is a classic cookie mistake. Overmixing develops the gluten in the flour too much, leading to tough, dense cookies instead of soft and chewy ones. Mix the dry ingredients into the wet ingredients only until just combined, with no visible streaks of flour.
Using Cold Butter: Softened butter is crucial for proper creaming with the sugars, which incorporates air and creates a light, tender cookie. If your butter is too cold, it won’t cream properly, resulting in a denser cookie. If it’s too warm (melted), the cookies might spread too much. Aim for butter that gives slightly when pressed.
Overbaking: S’mores cookies are best when they are slightly underbaked in the center, allowing them to remain soft and gooey. Bake until the edges are lightly golden and the centers still look a little soft. They will continue to cook slightly as they cool on the hot baking sheet.
Not Lining Baking Sheets: Without parchment paper or silicone mats, the cookies, especially with melted marshmallow, are prone to sticking, making them difficult to remove and potentially ruining their shape.
Crowding the Baking Sheet: Placing cookies too close together on the baking sheet will prevent them from baking evenly and can cause them to spread into each other. Leave at least 2 inches between each cookie.
Incorrect Sourdough Discard Hydration: This recipe assumes a 100% hydration sourdough discard (equal parts flour and water by weight). If your discard is significantly different, it might affect the dough consistency. For best results, use discard that is active but unfed, or at least a few hours past its peak
