Ingredients You’ll Need for Copycat Crumbl Lucky Charms Cookies

To capture that iconic Crumbl taste and texture, you’ll need a mix of simple pantry staples and, of course, the star of the show—Lucky Charms cereal.

Here’s everything you’ll need:

For the Cookie Dough:

  • 2 ½ cups all-purpose flour – Provides structure for thick, bakery-style cookies.
  • 1 teaspoon baking powder – Helps the cookies rise slightly without becoming cakey.
  • ½ teaspoon baking soda – Adds to the chewy texture.
  • ½ teaspoon salt – Balances the sweetness and enhances flavor.
  • 1 cup unsalted butter (softened) – For a rich, buttery base.
  • 1 cup granulated sugar – Adds sweetness and a slight crispness to the edges.
  • ½ cup light brown sugar (packed) – Contributes moisture and a hint of caramel flavor.
  • 2 large eggs – Binds the ingredients together and adds richness.
  • 2 teaspoons pure vanilla extract – Deepens the flavor profile.
  • 1 ½ cups Lucky Charms cereal (slightly crushed) – Adds a fun, colorful crunch inside the cookie dough.

For the Marshmallow Frosting:

  • ½ cup unsalted butter (softened) – Creates a smooth, creamy frosting base.
  • 1 cup marshmallow fluff – Gives the frosting a light, airy, and sweet marshmallow flavor.
  • 2 cups powdered sugar – Sweetens and thickens the frosting for the perfect spreadable consistency.
  • 2–3 tablespoons heavy cream (or milk) – Adjusts the frosting’s texture, making it silky and smooth.
  • 1 teaspoon vanilla extract – Adds warmth and depth to the frosting flavor.

For the Topping:

  • Optional: White chocolate chips (melted for drizzling) or edible glitter for extra flair.

Step-by-Step Instructions to Make Copycat Crumbl Lucky Charms Cookies

Ready to bring a little Crumbl magic into your kitchen? Just follow these simple steps:

Step 1: Prepare the Cookie Dough

  1. Preheat Your Oven: Set it to 350°F (175°C). Line two baking sheets with parchment paper to prevent sticking.
  2. Cream the Butter and Sugars: In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy (about 2–3 minutes). This creates a soft, tender texture.
  3. Add the Eggs and Vanilla: Mix in the eggs one at a time, followed by the vanilla extract. Beat until fully combined.
  4. Mix the Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
  5. Combine Wet and Dry: Gradually add the dry ingredients to the wet mixture, mixing until just combined—avoid overmixing to keep the cookies tender.
  6. Fold in the Cereal: Gently fold in the crushed Lucky Charms cereal, distributing it evenly throughout the dough.

Step 2: Shape and Bake the Cookies

  1. Portion the Dough: Use a large cookie scoop or measure about ¼ cup of dough for each cookie. Roll into balls and slightly flatten them on the prepared baking sheet.
  2. Bake: Place the cookies in the preheated oven and bake for 10–12 minutes, or until the edges are set but the centers are still soft.
  3. Cool Completely: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This helps them set without overbaking.

Step 3: Make the Marshmallow Frosting

  1. Beat the Butter: In a clean bowl, beat the softened butter until creamy and smooth.
  2. Add the Marshmallow Fluff and Vanilla: Mix in the marshmallow fluff and vanilla extract until well combined.
  3. Incorporate the Powdered Sugar: Gradually add the powdered sugar, beating on low speed to start, then increasing to medium until fluffy.
  4. Adjust the Consistency: Add 1 tablespoon of cream at a time until the frosting reaches a smooth, spreadable consistency.

Step 4: Decorate Your Cookies

  1. Frost the Cookies: Once the cookies are completely cool, spread a generous layer of marshmallow frosting on top of each one.
  2. Add the Finishing Touch: Sprinkle Lucky Charms marshmallows over the frosting. Press them lightly to help them stick.
  3. Optional: Drizzle with melted white chocolate or a dusting of edible glitter for extra fun and flair.

Step 5: Serve and Enjoy

Your Copycat Crumbl Lucky Charms Cookies are ready to enjoy!

Soft, chewy, sweet, and colorful—just like the Crumbl favorite, but fresh from your own kitchen.

Baking Tips for Perfect Copycat Crumbl Lucky Charms Cookies

Achieving that signature Crumbl cookie texture—soft, thick, and chewy with just the right amount of crunch—comes down to a few simple baking techniques.

Here are some expert tips to help you bake these Lucky Charms cookies to perfection:

1. Don’t Skip the Chill (Optional but Recommended)

While not mandatory, chilling the dough for 30 minutes before baking can help control spreading, resulting in thicker, chewier cookies.

If you prefer that classic Crumbl-style thickness, this step is worth it.

2. Use Room Temperature Ingredients

Ensure your butter and eggs are at room temperature before mixing.

This allows for even blending, which helps create a smooth, cohesive dough and promotes a tender crumb in the finished cookies.

3. Measure Flour Correctly

Too much flour can lead to dense cookies. Use the spoon-and-level method: spoon flour into your measuring cup, then level it off with a knife.

This ensures you’re not packing in more flour than needed.

4. Separate the Marshmallows for Best Results

When adding Lucky Charms to the dough, separate the marshmallows from the cereal.

Add the crushed cereal to the dough for texture, and save the colorful marshmallows for decorating after baking.

This prevents the marshmallows from melting or burning in the oven.

5. Slightly Underbake for Soft Centers

Crumbl cookies are known for their soft, gooey centers.

To achieve this, remove the cookies from the oven when the edges are just golden but the centers still look slightly underdone.

They’ll continue to set as they cool.

6. Cool Completely Before Frosting

Resist the urge to frost warm cookies—this can cause the marshmallow frosting to melt and slide off. Let the cookies cool completely on a wire rack for the best frosting results.

Storing and Freezing Instructions

Whether you’re making these cookies ahead of time or saving leftovers (if there are any!), proper storage ensures they stay fresh and delicious.

How to Store Lucky Charms Cookies:

  • At Room Temperature: Place the frosted cookies in an airtight container, layering parchment paper between them to prevent sticking. They’ll stay fresh for up to 4 days at room temperature.
  • In the Refrigerator: If your kitchen is warm, you can refrigerate the cookies. Just be sure to let them come to room temperature before serving to restore their soft, chewy texture.

How to Freeze Lucky Charms Cookies:

Freezing these cookies is a great option if you want to make a batch ahead of time.

1. Freezing Unfrosted Cookies:

  • Bake the cookies as directed, then let them cool completely.
  • Place them in a single layer on a baking sheet and freeze until solid.
  • Transfer to a freezer-safe bag or container with parchment paper between layers.
  • Storage Time: Up to 2 months.
  • To Serve: Thaw at room temperature, then frost and decorate as usual.

2. Freezing Cookie Dough:

  • Scoop the dough into balls and place them on a baking sheet lined with parchment paper.
  • Freeze until solid, then transfer to a freezer bag.
  • Baking from Frozen: No need to thaw—just add an extra 1–2 minutes to the baking time.

3. Freezing Frosted Cookies (Optional):

While it’s possible to freeze frosted cookies, the marshmallow frosting can become slightly tacky when thawed.

For best results, freeze unfrosted cookies and add the frosting fresh after thawing.

Recipe Variation:

If you’d like to put your own twist on these Copycat Crumbl Lucky Charms Cookies, here are a few fun variations to try:

  1. Chocolate Chip Twist: For an extra indulgent treat, add a handful of semi-sweet chocolate chips to the cookie dough along with the Lucky Charms cereal.

    The chocolate complements the sweetness of the marshmallow frosting beautifully.
  2. Peanut Butter Version: Replace half of the butter in the cookie dough with peanut butter for a nutty twist.

    The combination of peanut butter and Lucky Charms creates a fun flavor contrast.
  3. Mini Cookies: If you want to make bite-sized treats, use a smaller cookie scoop (about 1 tablespoon of dough per cookie).

    These mini cookies are perfect for a quick snack or party platter.
  4. Gluten-Free Option: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend to make these cookies gluten-free.

    Be sure to double-check that the cereal and marshmallow fluff you’re using are also gluten-free.
  5. Coconut Flavor: Add ½ cup of shredded coconut to the dough for a tropical flavor that pairs well with the Lucky Charms marshmallows and frosting.

Serving Suggestions:

Party Treats: These cookies are a showstopper for any event.

Serve them at birthday parties, St. Patrick’s Day celebrations, or any festive occasion.

The bright colors and nostalgic flavors are sure to be a hit with both kids and adults!

Dessert Platter: Place these cookies on a dessert table alongside other sweet treats like brownies, cupcakes, and mini cheesecakes.

They’re just the right combination of soft, sweet, and chewy.

Frequently Asked Questions (FAQs)

1. Can I Use Regular Marshmallows Instead of Lucky Charms Marshmallows?

Yes, you can substitute regular mini marshmallows if you don’t have Lucky Charms marshmallows on hand.

However, the flavor and colorful look will be slightly different. For the closest Crumbl copycat experience, the cereal marshmallows are recommended.

2. How Do I Make These Cookies Gluten-Free?

To make a gluten-free version, simply swap the all-purpose flour with a high-quality 1:1 gluten-free flour blend.

Additionally, check the Lucky Charms cereal packaging to ensure it’s labeled gluten-free, as ingredients can vary by brand.

3. Can I Prepare the Dough Ahead of Time?

Absolutely! You can make the cookie dough up to 48 hours in advance.

Store it in the refrigerator, covered tightly, until ready to bake.

For even longer storage, freeze the dough balls and bake directly from frozen (just add 1–2 extra minutes to the baking time).

4. Why Did My Cookies Spread Too Much While Baking?

If your cookies spread more than you’d like, a few factors could be at play:

  • The butter may have been too warm—try chilling the dough before baking.
  • Too little flour can cause spreading—double-check your measurements.
  • Baking on a warm cookie sheet can also cause spreading—always use a cool sheet for each batch.

5. Can I Use a Different Type of Frosting?

While the marshmallow frosting complements the Lucky Charms theme perfectly, you can certainly experiment with other frostings.

A simple vanilla buttercream or a cream cheese frosting would also pair well with these cookies.

6. How Do I Keep the Lucky Charms Marshmallows from Getting Soggy?

To keep the marshmallows crisp and colorful:

  • Add them only after the cookies have completely cooled and been frosted.
  • Store the cookies in an airtight container at room temperature, avoiding humid environments.

7. Can I Make Smaller Cookies Instead of Crumbl’s Giant Size?

Definitely! Just use a smaller scoop for the dough and adjust the baking time. Start checking for doneness around 7–8 minutes.

You’ll still get the same delicious flavor in a more snackable size.
