Step‑by‑Step Instructions for Sourdough S’mores Cookies

Step 1: Brown the Butter
In a saucepan over medium heat, melt 1 cup of unsalted butter, stirring occasionally. Cook until the butter turns golden brown and develops a nutty aroma, about 10-15 minutes. Watch closely to avoid burning, then remove from heat and let it cool slightly, allowing the flavors to deepen while you prepare the other ingredients.

Step 2: Mix Wet Ingredients
In a large mixing bowl, combine the cooled brown butter with 1 cup of brown sugar and ½ cup of granulated sugar. Using a hand mixer or whisk, blend until creamy and well incorporated. Add in 2 large eggs and 2 teaspoons of vanilla extract, mixing until the mixture is smooth and light in color, ensuring all ingredients are well combined.

Step 3: Combine Dry Ingredients
In a separate bowl, whisk together 2 ½ cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder, and ½ teaspoon of salt. This dry mixture will help your Sourdough S’mores Cookies achieve the perfect texture, so make sure to thoroughly combine all ingredients before gradually adding it to the wet mixture.

Step 4: Incorporate Dry with Wet
Carefully fold the dry ingredients into the wet mixture, using a spatula to combine gently. Mix until just incorporated, being mindful not to overmix, which can result in tough cookies. You want a soft dough that looks slightly shaggy, perfect for the upcoming mix-ins that will elevate your Sourdough S’mores Cookies.

Step 5: Fold in Mix-ins
Once the dough is formed, gently fold in 1 cup of semi-sweet chocolate chunks, 1 cup of mini marshmallows, and 1 cup of chopped graham crackers. This step adds that beloved s’mores flavor. Ensure that the mix-ins are distributed evenly throughout the dough, creating pockets of gooey goodness and crunchy bits in your cookies.

Step 6: Chill Dough (Optional)
For thicker, chewier cookies, cover the dough and refrigerate it for 30-60 minutes. Chilling allows the flavors to meld and improves the dough’s texture. While the dough cools, you can preheat your oven and prepare the baking sheets, ensuring your Sourdough S’mores Cookies turn out perfectly.

Step 7: Bake
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. Scoop 2 tablespoons of dough per cookie onto the sheets, spacing them about 2 inches apart to allow for spreading. Bake for 12-14 minutes until the edges are golden brown, but the centers remain soft and slightly underbaked for the ultimate chewy texture.

Step 8: Cool
After baking, allow the Sourdough S’mores Cookies to cool on the baking sheet for about 5 minutes, during which they will continue to set. Then, carefully transfer them to a wire rack to cool completely. This cooling step is crucial for maintaining the gooey centers and enhancing the delightful contrast of textures.

Expert Tips for Sourdough S’mores Cookies

Brown the Butter Right: Ensure your butter is perfectly browned; burnt butter can overshadow the delicate flavors in your Sourdough S’mores Cookies.
Chill for Chewiness: Chilling the dough for at least 30 minutes will create thicker, chewier cookies. Don’t skip this step for the best texture!
Space is Key: Keep at least 2 inches between cookie dough scoops on the baking sheet to prevent overcrowding and allow plenty of space for spreading.
Underbake for Gooeyness: For that perfect gooey center, bake the cookies until the edges are golden but the center appears slightly underbaked. They’ll firm up while cooling.
Mix-Ins Variation: Feel free to substitute dark chocolate or add nuts for extra flavor. Swirling in peanut butter after adding chocolate and marshmallows can add a delightful twist!

Make Ahead Options

These Sourdough S’mores Cookies are perfect for those busy weeknights when you crave a homemade treat! You can prepare the cookie dough up to 24 hours in advance; simply store it in the refrigerator in an airtight container to maintain freshness. Additionally, if you want to get a head start on baking, you can scoop the dough onto baking sheets and freeze the dough balls for up to 3 months; this allows you to bake cookies straight from the freezer—just add an extra 1-2 minutes to the baking time. To keep your cookies just as delicious when you’re ready to enjoy them, ensure you slightly underbake them; they’ll continue to set as they cool, resulting in soft, gooey centers every time!

Sourdough S’mores Cookies Recipe FAQs

To keep them at their best, store the cookies in an airtight container at room temperature for up to 3 days. However, if you happen to have leftovers (which is rare!), you can store them in the fridge for about 5 days, allowing them to return to room temperature before enjoying.

What can I do if my butter burns while browning?
If your butter burns, it’s best to start over. You can’t salvage burnt butter, as the flavor can overpower your cookies. Remember, you want a nutty aroma and a deep golden color, so keep an eye on it and stir regularly to ensure it cooks evenly.

Are these cookies safe for pets or those with allergies?
While Sourdough S’mores Cookies are a delightful treat for humans, they contain ingredients like chocolate and sugar that are harmful to pets.
