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

1. Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking soda, and salt. Set this aside while you work on the wet ingredients.

2. Cream the Butter and Sugars

Using a hand mixer or stand mixer, beat the softened butter, brown sugar, and cream cheese together until the mixture looks light and fluffy. This takes about 3 minutes. The mixture should be smooth with no lumps.

3. Add Eggs and Vanilla

Mix in the egg, vanilla extract, and vanilla emulsion until everything is well combined. Scrape down the sides of the bowl to make sure nothing gets left behind.

4. Combine Wet and Dry Ingredients

Add the flour mixture to the butter mixture. Mix on low speed until just combined. The dough will be thick and slightly sticky.

5. Fold in Mix-Ins

Using a rubber spatula, gently fold in the white chocolate chips and Lucky Charms marshmallows. Make sure they are spread evenly throughout the dough.

6. Chill the Dough

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This helps the cookies hold their shape while baking and improves the texture.

7. Scoop and Bake

Preheat your oven to 350 degrees. Line baking sheets with parchment paper. Scoop the dough into large portions using a 2-tablespoon cookie scoop. Place them about 3 inches apart on the baking sheets. Bake for 10 to 12 minutes until the edges are set but the centers still look slightly soft. The cookies will continue cooking as they cool.

8. Cool Completely

Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely before frosting.

9. Make the Frosting

Beat together the marshmallow cream, softened butter, cream cheese, and powdered sugar until smooth and fluffy. This takes about 2 minutes.

10. Decorate

Spread a generous amount of frosting on each cooled cookie. Top with extra Lucky Charms marshmallows while the frosting is still soft so they stick.

Serving and Decoration

These cookies look best when generously frosted and topped with plenty of colorful marshmallows. Arrange them on a pretty plate or in a bakery box for gifting. Serve with cold milk for the full experience. They make wonderful treats for birthday parties, bake sales, or just because. Kids especially love helping decorate these cookies.

How to Serve Lucky Charms Cookies

• With Milk: The classic pairing that never gets old.
• Ice Cream Sandwiches: Sandwich vanilla ice cream between two cookies.
• Dessert Boards: Add to a dessert charcuterie board with other sweet treats.
• Gift Boxes: Package in clear bags with ribbons for homemade gifts.
• Party Platters: Perfect for kids’ birthday parties or St. Patrick’s Day celebrations.

Storing Lucky Charms Cookies

• Room Temperature: Store unfrosted cookies in an airtight container for up to 5 days.
• Frosted Cookies: Keep frosted cookies in a single layer in an airtight container for up to 3 days. The frosting stays soft and delicious.
• Freezing: Freeze unfrosted cookies for up to 3 months. Thaw at room temperature before frosting and serving.
• Cookie Dough: Freeze scooped cookie dough balls on a baking sheet, then transfer to a freezer bag. Bake from frozen, adding 2 extra minutes to the bake time.

Tips and Tricks for Success

• Room Temperature Ingredients: Make sure your butter, cream cheese, and egg are at room temperature for the smoothest dough.
• Don’t Overbake: These cookies should look slightly underdone in the center when you take them out. They will firm up as they cool.
• Separate the Marshmallows: Pick out just the marshmallows from the Lucky Charms cereal for the best results. You can save the cereal pieces for breakfast.
• Chill the Dough: Skipping the chill time makes the cookies spread too much and lose their thick, bakery-style shape.
• Use Parchment Paper: This prevents sticking and makes cleanup easy.
• Let Frosting Set: Give the frosting 15 minutes to set before stacking or packaging cookies.

Lucky Charms Cookies FAQs

Can I use the whole Lucky Charms cereal with the pieces? You can, but the marshmallows alone give better results. The cereal pieces can get hard when baked.

Why do my cookies spread too much? Make sure you chill the dough for the full 30 minutes. Also check that your butter is softened but not melted.

Can I make these without cream cheese? The cream cheese makes these cookies extra soft and special. You could add more butter instead, but the texture will be different.

How do I keep the marshmallows from melting in the oven? Folding them into chilled dough helps. Some melting is normal and creates nice pockets of gooey sweetness.

Can I use vanilla extract only instead of extract and emulsion? Yes, just use 2 tablespoons of vanilla extract total if you cannot find vanilla emulsion.

How do I know when the cookies are done? The edges should be set and lightly golden, but the centers will still look soft. They firm up as they cool.
