Step‑by‑Step Instructions for Sourdough Monster Cookies

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats, line a baking sheet with parchment paper or lightly grease it to prevent the Sourdough Monster Cookies from sticking. This initial prep ensures a smooth baking process and perfectly baked cookies.

Step 2: Cream the Butter and Sugars
In a mixing bowl, combine the softened unsalted butter, granulated sugar, brown sugar, and vanilla extract. Using a hand or stand mixer, cream these ingredients together on medium speed until the mixture turns light and fluffy, which should take about 3-5 minutes. This step is vital for adding air and creating a soft texture in your cookies.

Step 3: Incorporate the Egg
Add one large egg to the creamed mixture and mix until fully combined. The egg not only moisten the dough but also binds all the ingredients together. Continue mixing on low speed for about 30 seconds, ensuring that everything is smoothly blended without any streaks of egg remaining.

Step 4: Add Dry Ingredients
Gently incorporate the all-purpose flour, old-fashioned oats, sourdough discard, salt, baking soda, and baking powder into the wet mixture. Mix on low speed until the dough just comes together, being careful not to overmix. You’ll know it’s ready when no dry flour is visible and the dough is thick and slightly sticky.

Step 5: Fold in the Mix-ins
Using a large spoon or spatula, fold in the chocolate chips and M&Ms. This adds delightful sweetness and color to your Sourdough Monster Cookies, creating a treat that’s both delicious and visually appealing. Ensure the mix-ins are evenly distributed throughout the cookie dough for balanced flavor in every bite.

Step 6: Shape the Cookies
Scoop out about two tablespoons of dough for each cookie, rolling them into balls between your palms. Place the dough balls about 2 inches apart on the prepared baking sheet to allow for spreading. This shaping ensures that your cookies maintain a nice, round form during baking, leading to the perfect cookie experience.

Step 7: Bake to Perfection
Slide the baking sheet into your preheated oven and bake the Sourdough Monster Cookies for 10-12 minutes, or until the edges are lightly golden. Keep an eye on them, as baking times may vary based on your oven. They should be soft in the center but set around the edges when done.

Step 8: Cool Down
Once baked, remove the cookies from the oven and let them rest on the baking sheet for 10 minutes. This resting period allows them to firm up slightly before transferring. Afterward, move your Sourdough Monster Cookies to a cooling rack to cool completely, enjoying their delightful aroma wafting through your kitchen.

Make Ahead Options

These Sourdough Monster Cookies are ideal for busy bakers looking to prep in advance! You can mix the cookie dough up to 24 hours ahead of time; just cover it tightly with plastic wrap and refrigerate to maintain freshness. If you want to take it a step further, you can form the cookie dough balls and freeze them for up to 3 months. When you’re ready to bake, simply place the frozen dough on a baking sheet and add an extra minute or two to the baking time. This way, you can enjoy freshly baked cookies with minimal effort, all while making the most of your meal prep!

Sourdough Monster Cookies Recipe FAQs

How do I select the best sourdough discard for my cookies?
Absolutely! For Sourdough Monster Cookies, choose a discard that has been recently fed if possible. Look for a discard that is bubbly and slightly tangy. Avoid using overly sour or watery discard, as it might affect the final taste and texture of the cookies.

What’s the best way to store Sourdough Monster Cookies?
I recommend storing your cookies in an airtight container at room temperature for up to 4 days. This will keep them soft and delicious. If you live in a particularly warm or humid climate, you may want to refrigerate them to preserve their freshness for an extended period, up to a week.

Can I freeze Sourdough Monster Cookies or their dough?
Very! To freeze, wrap each cookie individually in plastic wrap or foil and place them in a freezer-safe bag. They can maintain their quality for up to 3 months. If you prefer freezing the dough, shape the cookie balls and freeze them on a baking sheet first. Once frozen, transfer the dough balls to a freezer bag, and they can be baked straight from the freezer, adding an extra minute or two to the baking time.

What should I do if my cookies turn out dry?
If your Sourdough Monster Cookies come out dry, this could be due to the amount of flour used. Next time, try reducing the flour by a couple of tablespoons or experimenting with adding a bit more peanut butter or even another egg. Also, ensure your butter is at room temperature for better blending!

Are there any dietary considerations for Sourdough Monster Cookies?
While these cookies are family-friendly, some are concerned about allergens like gluten and nuts. If you’re baking for those with allergy concerns, opt for gluten-free flour blends and use almond butter or sunflower seed butter instead of peanut butter. Always double-check ingredients to ensure they align with your dietary needs!

Can I make any substitutions for the ingredients?
Of course! You can swap the creamy peanut butter for almond butter or sunflower seed butter for a nut-free option. Feel free to replace chocolate chips and M&Ms with dried fruits, nuts, or even seeds for a different flavor profile. Get creative with your mix-ins to make these cookies uniquely yours!
