How to Make Sourdough S’mores Cookies with vegan marshmallows and Brown Butter
Step 1: Brown the Butter
Start by browning the butter in a small saucepan over medium heat. Stir continuously until it becomes bubbly and turns dark golden. Browning the butter is key here as it enhances the flavor, giving your cookies a delightful nuttiness.
Step 2: Cool the Butter
Once browned, remove from heat and let the butter cool completely to room temperature. This step is crucial because adding hot butter can affect the texture of your cookie dough.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together your dry ingredients: flour, baking powder, baking soda, and salt. Mixing these first ensures that your leavening agents distribute evenly throughout the dough.
Step 4: Mix Wet Ingredients
In a large mixing bowl, combine the cooled brown butter with sugar, vanilla extract, and sourdough starter. Use a whisk or hand mixer until everything is well blended. This mixture creates the base for our rich cookie dough.
Step 5: Fold in Dry Ingredients
Gently fold in your combined dry ingredients into the wet mixture until just incorporated. This ensures your cookies stay tender without overmixing.
Step 6: Add Chocolate & Marshmallows
Now it’s time to add those delicious elements! Stir in dark chocolate chunks, mini chocolate chips, crushed graham crackers, and mini vegan marshmallows. The more mix-ins, the better!
Step 7: Shape Cookie Dough
Line your cookie sheet with parchment paper. Scoop about two tablespoons of chilled cookie dough and shape them into balls. Spacing them out is important as they will spread while baking.
Step 8: Preheat Oven
Preheat your oven to 375°F (190°C). Getting this right helps achieve that perfect bake we all crave!
Step 9: Bake Cookies
Place your cookie dough balls on the lined sheet about two to three inches apart. Bake them for about 12-15 minutes until they look puffy and golden around the edges.
Step 10: Flatten Cookies
Remove them from the oven and lift the parchment paper about a foot above the pan before dropping it back down. This helps flatten them perfectly! If needed, use a butter knife around the edges for shaping.
Step 11: Cool Down
Let those adorable cookies cool completely on the cookie sheet before indulging. They’ll firm up nicely as they cool down.
Enjoy sharing these delightful Sourdough S’mores Cookies with vegan marshmallows and Brown Butter with friends and family—it’s hard not to love every gooey bite!
Pro Tips for Making Sourdough S’mores Cookies with Vegan Marshmallows and Brown Butter
Making these cookies is a delightful adventure, and a few pro tips can help you achieve cookie perfection!
-
Use room temperature ingredients: Allow your sourdough starter, butter, and any other refrigerated items to come to room temperature. This helps the ingredients blend more smoothly and results in a better texture.
-
Chill the dough: If you have time, chilling the cookie dough for at least 30 minutes before baking helps prevent spreading and enhances the flavors. It allows the flour to absorb moisture, leading to chewier cookies.
-
Don’t skip browning the butter: Browning the butter adds a rich, nutty flavor that elevates these cookies beyond ordinary. The caramelization process also contributes to a lovely color and depth of flavor.
-
Adjust baking time for your oven: Every oven is different! Keep an eye on your cookies in the last few minutes of baking to ensure they don’t overbake. They should be golden brown on the edges but still soft in the center.
-
Experiment with add-ins: Feel free to get creative! Try adding nuts or swapping out chocolate types for different flavor profiles. Each variation can bring a new twist to this classic treat.
