Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper. This important first step creates the perfect baking environment for your Chocolate Marshmallow Swirl Cookies, ensuring even heat distribution and easy cookie removal once they’re baked.
Step 2: Mix Dry Ingredients
In a medium-sized bowl, whisk together 1 ¾ cups of all-purpose flour, ½ cup of cocoa powder, 1 teaspoon of baking soda, and ½ teaspoon of salt until well combined. This mixture will create a delightful chocolate foundation for your cookies. Setting aside the dry ingredients will help you smoothly incorporate them later while ensuring the perfect texture in your cookie dough.
Step 3: Cream Butter and Sugars
Next, in a large mixing bowl, beat together ½ cup of softened unsalted butter, ¾ cup of granulated sugar, and ¾ cup of brown sugar with a hand mixer or stand mixer for about 2-3 minutes. Once the mixture is light and fluffy, you’ll notice a creamy texture that’s ready to bind the ingredients together, setting the stage for your Chocolate Marshmallow Swirl Cookies.
Step 4: Incorporate Egg and Vanilla
Add in one medium-sized egg and 1 teaspoon of pure vanilla extract to the butter-sugar mixture. Mix until fully incorporated, which should take about 30-60 seconds. This combination adds moisture and a burst of flavor that truly enhances your cookie dough’s richness, bringing your cookies one step closer to perfection.
Step 5: Combine Dry and Wet Ingredients
Gradually mix the dry ingredients into the wet mixture, blending with low speed until just combined. Avoid overmixing; you want the ingredients to come together without losing the lightness that makes your Chocolate Marshmallow Swirl Cookies chewy yet soft. Stop mixing once you see no dry flour remaining.
Step 6: Fold in Chocolate Chips
Once your dough is combined, gently fold in 1 cup of semi-sweet chocolate chips using a spatula. This step is all about incorporating melty chocolate goodness into your dough, ensuring that each cookie has those delicious bursts of flavor in every bite.
Step 7: Add Mini Marshmallows
Carefully fold in 1 cup of mini marshmallows, along with marshmallow fluff if using, creating the signature swirl in your cookie dough. The marshmallows should be evenly distributed but still visible, as their gooeyness will enhance the texture of your Chocolate Marshmallow Swirl Cookies when baked.
Step 8: Scoop the Dough
Using a cookie scoop or tablespoon, drop rounded dough onto the lined baking sheets, spacing them about 2 inches apart. This spacing is crucial as the cookies will spread during baking, allowing for even cooking and preventing the gooey marshmallows from merging too much.
Step 9: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 8-10 minutes until the edges are set and the centers appear soft. Keep a close eye on the cookies; you want to see slightly toasted marshmallow edges indicating that they’re perfectly baked.
Step 10: Cool and Serve
After baking, let the cookies cool on the baking sheets for about 5 minutes. Then, transfer them to a wire rack to cool completely. This cooling period allows the flavors to meld and the marshmallows to settle, ensuring every bite of your Chocolate Marshmallow Swirl Cookies is a chewy, gooey delight.
