How to Make Lucky Charms Cookies Copycat
Step 1. Begin by preheating your oven so that it’s hot enough by the time your cookies are ready to bake. Position your oven rack in the center for even cooking. Once preheated, line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
Step 2. In a mixing bowl, combine the flour, baking soda, baking powder, and salt. Whisk these dry ingredients together until they are fully blended. The baking soda and baking powder will help the cookies rise, while the salt enhances their flavor.
Step 3. In a separate bowl, beat the room-temperature unsalted butter with granulated sugar until the mixture becomes light and fluffy. This process adds air into the butter, which is essential for creating a nice texture in the cookies. You should see a noticeable change in volume and a lighter color when it’s ready.
Step 4. Add the large egg and vanilla extract to the butter and sugar mixture. Mix until everything is fully combined. The egg acts as a binding agent that helps hold the cookies together, while the vanilla extract provides a warm, inviting flavor.
Step 5. Gradually incorporate the dry mixture into the wet ingredients. Gently fold them together until they are just combined, being careful not to overmix. The dough should be soft and slightly sticky, ready for the Lucky Charms.
Step 6. Fold in the 1 1/2 cups of Lucky Charms cereal, ensuring they are evenly dispersed throughout the dough. This cereal adds crunch and a fun burst of sweetness to each cookie. You’ll want to mix enough so that all the cereal is coated, but still handle the dough gently.
Step 7. Scoop out portions of the dough and place them onto the prepared baking sheet, spacing them a bit apart to allow for spreading while baking. Each scoop should be about the size of a golf ball. The cookies will spread slightly, so give them some room.
Step 8. Bake the cookies in the preheated oven until they are lightly golden around the edges, which usually should take about 10 to 12 minutes. Watch for the edges to firm up while the centers remain soft; this will give you a chewy cookie once cooled.
Step 9. Once baked, allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. This will help them set without falling apart. They will continue to firm up as they cool down.
Step 10. For the frosting, beat together the room temperature butter, powdered sugar, milk, vanilla extract, and salt until it’s smooth and creamy. The frosting should have a spreadable consistency but still hold its shape well enough to stay on the cookies.
Step 11. Once the cookies are completely cooled, generously spread the frosting on top of each one. Take care to cover them evenly, and feel free to swirl it a bit for a nice texture.
Step 12. Finally, sprinkle the remaining Lucky Charms cereal on top of the frosted cookies for a colorful and decorative finish. This adds not only a lovely visual touch but also an extra crunch.

Serving Suggestions

Pro Tips for Best Results
- Make sure your butter is truly at room temperature for easy mixing.
- Don’t overmix once you add the flour; this can yield tougher cookies.
- If the dough feels too sticky, allowing it to chill for a short period can help.
- Adjust the sprinkle of Lucky Charms on top based on your preference for crunch.
- Use a cookie scoop for uniform sizing to ensure even baking.
- Allow enough cooling time before frosting to prevent melting.
Common Mistakes to Avoid
- Using Cold Butter: Cold butter won’t cream well with the sugar, leading to dense cookies. Make sure to let your butter sit out for a bit to soften before starting.
- Overmixing the Dough: Mixing too much after adding the flour can develop gluten and make the cookies tough. Mix just until combined for a tender texture.
- Not Preheating the Oven: Baking in an unpreheated oven can lead to unevenly baked cookies. Always take the time to properly preheat for optimal results.
- Skipping the Parchment Paper: Not lining the baking sheet can cause sticking. Parchment paper ensures easy removal and keeps cookies intact.
- Baking Too Long: Overbaking can lead to dry cookies. Watch for the edges to harden while the centers remain soft for the best chewy texture.
- Too Much Frosting: While frosting is delicious, adding too much can overwhelm the cookie and make it overly sweet. Use just enough to complement the cookie balance.
Variations & Substitutions
Feel free to experiment with different flavors of extract or mix in some mini chocolate chips for added richness. You can also reduce the sugar slightly if you prefer a less sweet cookie. For those who enjoy toasted coconut, adding some to the dough can provide a new flavor layer while still keeping the base intact.
Storage & Reheating
Store the cookies at room temperature in an airtight container for up to a week to maintain freshness. If you have leftover cookies that are frosted, placing a piece of parchment between layers will help prevent sticking. If using within two weeks, refrigeration is fine, but they can also be frozen for longer preservation. For reheating, place in the microwave for just a few seconds to soften slightly without compromising texture.
Frequently Asked Questions
Can I make this recipe ahead of time?
Yes, you can prepare the cookie dough in advance and store it in the refrigerator for up to two days before baking. This allows the flavors to meld a bit more, and you can bake fresh cookies when you’re ready.
How long does it last in the fridge?
These cookies can last up to a week in the refrigerator in an airtight container. If they have frosting, just ensure they’re well protected from air.
Can I freeze this recipe?

What can I substitute for one ingredient?
While this recipe is quite specific, if you need to replace the whole milk, using a non-dairy milk can work without compromising the dough significantly.
