- 1 cup 200g granulated sugar
- 1/2 cup 100g light brown sugar, packed
- 2 large eggs room temperature
- 1 tbsp vanilla extract
- 2 3/4 cups 345g all-purpose flour
- 1 tbsp cornstarch
- 1/2 tsp baking soda
- 1/2 tsp baking powder
- 3/4 tsp salt
Mix-Ins
- 3/4 cup Lucky Charms cereal cereal pieces only, not marshmallows
Marshmallow Frosting
- 1/2 cup 113g unsalted butter, softened
- 1 1/2 cups 180g powdered sugar
- 1 cup marshmallow fluff
- 1/2–1 tsp vanilla extract
- Pinch of salt
- 1-2 tbsp heavy cream
Topping
- Lucky Charms cereal including marshmallows
Instructions
Cream Butter and Sugars
- In a large bowl, beat butter, granulated sugar, and brown sugar for 2–3 minutes until light and fluffy.
Add Eggs and Vanilla
- Mix in eggs one at a time, then add vanilla extract. Scrape down the bowl as needed.
Mix Dry Ingredients
- In a separate bowl, whisk together flour, cornstarch, baking soda, baking powder, and salt.
Combine Dough
- Gradually add dry ingredients to wet ingredients and mix until just combined. Do not overmix.
Fold in Cereal
- Gently fold in Lucky Charms cereal pieces (avoid marshmallows in the dough).
Scoop and Chill
- Scoop large portions (about 1/4 cup each), roll into balls, and slightly flatten into thick discs.
- Chill dough for 20–30 minutes for best results.
Bake
- Preheat oven to 350°F (175°C).
- Bake cookies for 10–12 minutes until edges are set and centers are soft.
Cool
- Allow cookies to cool on the baking sheet for 5–10 minutes, then transfer to a cooling rack. Cool completely before frosting.
Make Frosting
- Beat butter until smooth. Add powdered sugar, marshmallow fluff, vanilla, and salt. Beat until fluffy. Add heavy cream as needed for a smooth, spreadable consistency.
Assemble
- Spread or pipe frosting onto cooled cookies. Top with Lucky Charms cereal, including marshmallows.
Notes
- For thick, bakery-style cookies like Crumbl, slightly underbake the centers. The cookies will continue to set as they cool, giving you that soft, gooey texture.
- Always avoid baking the Lucky Charms marshmallows into the dough. They melt and can burn in the oven, so add them on top after frosting for the best flavor and appearance.
- Chilling the dough for 20–30 minutes helps prevent spreading and creates thicker, more professional-looking cookies. This step is especially important for achieving that classic Crumbl-style cookie shape.
- Use marshmallow fluff instead of melted marshmallows for the frosting. It creates a smoother, creamier texture that is easier to spread and more stable.
- If your frosting feels too thick, add a small amount of heavy cream (1 tablespoon at a time) until it reaches a soft, spreadable consistency.
- For picture-perfect cookies, use a round cookie cutter to gently shape the cookies immediately after baking while they are still warm.
- Add extra Lucky Charms cereal right before serving to keep the topping crunchy and colorful.
- Store cookies in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days. For best texture, bring to room temperature before serving.
Ingredient Notes
- Lucky Charms Cereal
Use mostly the cereal pieces in the dough and reserve the colorful marshmallows for topping. Baking the marshmallows can cause them to melt or burn, so adding them after frosting gives the best texture and appearance. - Marshmallow Fluff
Marshmallow fluff is key for the smooth, creamy frosting. It blends easily with butter and powdered sugar, creating that signature mallow creme texture. Avoid substituting with melted marshmallows, which can become sticky and uneven. - Unsalted Butter
Using real unsalted butter gives these cookies a rich, bakery-style flavor. Make sure it’s softened to room temperature so it creams properly with the sugar. - Brown Sugar
Brown sugar adds moisture and helps create a soft, chewy center. It also adds a slight caramel flavor that enhances the overall cookie. - Cornstarch
Cornstarch helps keep the cookies soft and thick by reducing gluten formation. This is one of the secrets to achieving that Crumbl-style texture. - All-Purpose Flour
Measure flour correctly using the spoon-and-level method to avoid dense cookies. Too much flour can make the cookies dry instead of soft and tender. - Heavy Cream
A small amount of heavy cream in the frosting helps create a smooth, spreadable consistency and gives the frosting a more professional, bakery-style finish. - Vanilla Extract
Vanilla enhances the overall flavor and helps create that classic sugar cookie taste. For best results, use pure vanilla extract.
Tips for Perfect Cookies
- Don’t Overbake
For soft, bakery-style cookies, remove them from the oven when the edges are set but the centers still look slightly underbaked. They will continue to firm up as they cool. - Chill the Dough for Thicker Cookies
Chilling the dough for 20–30 minutes helps prevent spreading and gives you that thick, Crumbl-style cookie texture. - Use a Large Cookie Scoop
For authentic bakery-style cookies, use a large scoop (about 1/4 cup). This creates thick, oversized cookies with soft centers. - Avoid Overmixing the Dough
Mix just until the ingredients are combined. Overmixing can lead to dense, tough cookies instead of soft and tender ones. - Shape Cookies While Warm
Right after baking, use a round cookie cutter to gently swirl around the edges. This creates perfectly round, professional-looking cookies. - Add Cereal Topping After Baking
Always add Lucky Charms marshmallows and cereal pieces after frosting. This keeps them crunchy and prevents melting or burning. - Let Cookies Cool Before Frosting
Frosting warm cookies will cause the marshmallow topping to melt and slide off. Make sure cookies are completely cooled first. - Adjust Frosting Consistency as Needed
If your frosting is too thick, add heavy cream 1 tablespoon at a time until it becomes smooth and spreadable.
Variations
- Fruity Pebbles Version
Swap Lucky Charms for Fruity Pebbles to create bright, fruity cereal cookies with a vibrant color and tangy-sweet flavor. - Cinnamon Toast Crunch Cookies
Use Cinnamon Toast Crunch cereal for a warm, cinnamon-sugar twist that pairs perfectly with the marshmallow frosting. - Chocolate Lover’s Version
Add white chocolate chips or milk chocolate chips to the dough for a richer, more indulgent cookie. - Cookie Sandwiches
Turn these into sandwich cookies by adding marshmallow frosting between two cookies for an extra decadent treat. - Mini Cookies
Make smaller cookies using a medium scoop for bite-sized versions that are perfect for parties or dessert trays. - Birthday Cake Style
Add rainbow sprinkles to the dough for a funfetti-style cookie that’s perfect for celebrations. - Extra Marshmallow Flavor
Mix a small amount of marshmallow fluff directly into the dough for an even stronger mallow creme flavor. - Gluten-Free Option
Use a 1:1 gluten-free flour blend to make gluten-free cereal cookies without sacrificing texture.
Storage Instructions
- Room Temperature
Store cookies in an airtight container at room temperature for up to 3 days. Keep them in a cool, dry place to maintain their soft texture. - Refrigerator
Store frosted cookies in an airtight container in the refrigerator for up to 5 days. Let them come to room temperature before serving for the best flavor and texture. - Freezing Cookies
Freeze unfrosted cookies in an airtight container or freezer-safe bag for up to 2 months. Thaw at room temperature and frost before serving. - Freezing Dough
You can freeze cookie dough balls for up to 2 months. Bake directly from frozen, adding 1–2 extra minutes to the baking time. - Best Texture Tip
For the best results, add the Lucky Charms topping right before serving to keep the cereal crunchy and fresh.
