The Charm of Chocolate Marshmallow Cookies

1. A Perfect Balance of Textures

These cookies bring together a trio of textures:
Soft and chewy cookie base – Thanks to the butter, brown sugar, and eggs, the cookies have a tender bite.
Chunks of creamy white chocolate – The richness of white chocolate balances the deep cocoa flavor.

2. A Nostalgic and Playful Twist

For many, Lucky Charms marshmallows are a childhood favorite, making these cookies feel like a whimsical trip down memory lane.

Magically Decadent Chocolate Marshmallow Cookies

Ingredients:

For the Cookies:

  • 1 cup (227g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 3/4 cup (150g) packed brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 1/4 cups (125g) unsweetened cocoa powder
  • 1 3/4 cups (219g) all-purpose flour
  • 1 cup (170g) white chocolate chunks
  • 1 cup Lucky Charms marshmallows

Optional Toppings:

  • Additional Lucky Charms marshmallows
  • Flaky sea salt

Directions:

  1. Preheat and Prepare:
    • Preheat your oven to 350°F (175°C).
    • Line two baking sheets with parchment paper or silicone baking mats.
  2. Cream Butter and Sugars:
    • In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar on medium-high speed until the mixture becomes light and fluffy, approximately 3–5 minutes.
    • Pause occasionally to scrape down the sides of the bowl to ensure even mixing.
  3. Incorporate Eggs and Vanilla:
    • Add the eggs one at a time, beating well after each addition until fully incorporated.
    • Mix in the vanilla extract until combined.
  4. Combine Dry Ingredients:
    • In a separate bowl, whisk together the baking soda, salt, cocoa powder, and all-purpose flour until well combined.
  5. Mix Wet and Dry Ingredients:
    • Gradually add the dry ingredients to the wet mixture, mixing on low speed.
    • Scrape down the sides of the bowl as needed, and mix until just combined. It’s acceptable if a few streaks of flour remain.
  6. Fold in Additions:
    • Gently fold in the white chocolate chunks and Lucky Charms marshmallows until evenly distributed throughout the dough.
  7. Shape the Cookies:
    • Using your hands or a cookie scoop, portion the dough into balls weighing approximately 60–75 grams each, depending on your preferred cookie size.
    • Place the dough balls onto the prepared baking sheets, spacing them adequately to allow for spreading.
    • Gently press the tops of the dough balls to slightly flatten them if a flatter cookie is desired.
    • For aesthetic appeal, press a few additional Lucky Charms marshmallows onto the tops of the cookies.
  8. Bake:
    • Bake the cookies in the preheated oven for 9–11 minutes.
    • The centers should appear slightly undercooked when removed from the oven to ensure a soft and chewy texture upon cooling.
  9. Optional Finishing Touch:
    • Immediately after removing the cookies from the oven, sprinkle them with flaky sea salt if desired.
  10. Cool:
    • Allow the cookies to cool on the baking sheets for 5–10 minutes before transferring them to a wire rack to cool completely.

Best Ways to Enjoy These Cookies

These cookies can be served in a variety of ways, making them a versatile treat for any occasion. Here are some of the best ways to enjoy them:

1. Classic Milk and Cookies Combo

Nothing beats the traditional pairing of warm cookies and cold milk. The richness of the cocoa contrasts beautifully with the creaminess of milk, making each bite even more satisfying.

2. Turn Them Into Ice Cream Sandwiches

Want to take them to the next level? Sandwich a scoop of vanilla or marshmallow ice cream between two cookies for an unbelievably decadent dessert. The creamy filling complements the chewy cookie texture perfectly.

3. Crumble Over Ice Cream

For a quick and easy dessert, crumble these cookies over a bowl of ice cream. The combination of warm chocolatey crumbs with cold, creamy ice cream is pure magic.

4. Pair with Hot Cocoa

For a cozy winter treat, enjoy these cookies alongside a steaming mug of hot cocoa. The extra marshmallowy goodness makes them a perfect match.

5. Use Them in a Dessert Charcuterie Board

Want to impress guests at your next gathering? Add these cookies to a dessert board with chocolate truffles, fruit, caramel sauce, and mini marshmallows for an irresistible sweet spread.

Baking Tips for the Best Cookies

Even the simplest cookie recipes have a few tricks that make them turn out perfectly soft, chewy, and flavorful. Here’s what you need to know:

1. Use Room Temperature Butter

Softened butter creams more easily with sugar, creating a smooth batter and ensuring a light, fluffy texture. If the butter is too cold, the dough will be too dense; if it’s melted, the cookies may spread too much.

2. Measure Your Flour Correctly

Too much flour can lead to dry, dense cookies. Always use the spoon-and-level method: spoon the flour into the measuring cup and level it off with a flat edge instead of scooping directly from the bag.

3. Chill the Dough for Thicker Cookies

For thicker, chewier cookies, refrigerate the dough for at least 30 minutes before baking. This helps prevent them from spreading too much in the oven.

4. Press Marshmallows on Top After Baking

Lucky Charms marshmallows can melt too much if mixed directly into the dough. To keep them vibrant and visible, press a few extra marshmallows onto the cookies immediately after baking while they’re still warm.

5. Bake Until Just Set

For chewy cookies, take them out of the oven when the edges are set but the centers still look slightly underbaked. They will continue cooking on the baking sheet as they cool.

Frequently Asked Questions (FAQs)

1. Can I use regular marshmallows instead of Lucky Charms?

Yes! If you don’t have Lucky Charms marshmallows, you can chop up regular mini marshmallows or use dehydrated marshmallows for a similar effect.

2. What type of cocoa powder is best?

For a rich chocolate flavor, use Dutch-process cocoa powder. If you prefer a slightly more bitter chocolate taste, use natural cocoa powder.

3. Can I make these cookies gluten-free?

Yes! Substitute the all-purpose flour with a 1:1 gluten-free baking blend, and make sure all other ingredients are gluten-free.

4. Can I freeze the cookie dough?

Absolutely! To freeze, scoop the dough into balls and place them on a baking sheet. Freeze until solid, then transfer them to a zip-top bag and store for up to 3 months. When ready to bake, place them on a cookie sheet and bake directly from frozen, adding 1–2 extra minutes to the baking time.

5. How do I store baked cookies?

Store the cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze them for up to 3 months.

6. Can I use a different type of chocolate?

Yes! While white chocolate contrasts beautifully with the cocoa-rich base, you can also use:

  • Milk chocolate chunks for extra creaminess.
  • Dark chocolate chips for a richer, bittersweet taste.
  • Peanut butter chips for a nutty twist.

7. How can I make these cookies extra chewy?

For extra chewiness, try adding an extra egg yolk to the dough and using more brown sugar than white sugar. The additional moisture keeps the cookies soft for days.

8. Can I add nuts for extra crunch?

Definitely! Chopped pecans, walnuts, or almonds would add a delicious nutty contrast to the soft texture of the cookies.
