Kitchen Tools You’ll Need
- Mixing bowls
- Baking sheet
- Rubber spatula
- Whisk
- Measuring cups and spoons
Ingredients
- 1 cup unsalted butter (softened for easy mixing)
- 1 ¼ cups granulated sugar (adds sweetness and texture)
- 1 egg (at room temperature for better incorporation)
- 2 teaspoons vanilla extract (enhances overall flavor)
- 2 ½ cups all purpose flour (provides structure)
- ½ teaspoon baking soda (helps cookies rise)
- ½ teaspoon baking powder (also contributes to rise)
- ¼ teaspoon salt (balances sweetness)
- 2 cups Lucky Charms marshmallows (adds texture and color, divided)

How to Make Lucky Charms Cookies
Step 1. Begin by preheating your oven to a warm temperature that’s suitable for baking cookies. This helps ensure that your cookies bake evenly and develop a lovely golden color.
Step 2. In a mixing bowl, combine the softened unsalted butter and granulated sugar. Use a whisk or rubber spatula to blend them together until the mixture is smooth and slightly fluffy. The goal here is to create a light texture that will help the cookies be tender.
Step 3. Crack the egg into the bowl and pour in the vanilla extract. Mix these in with the butter and sugar until everything is well combined, creating a smooth and creamy batter. This will add richness and extra flavor to your cookies.
Step 4. In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. This ensures that your leavening agents are evenly distributed throughout the flour, which helps your cookies rise uniformly.
Step 5. Gradually add the dry ingredients to the wet mixture. Stir gently until just combined, making sure not to overmix. The dough should be somewhat thick and slightly crumbly, which is ideal for cookies.
Step 6. Gently fold in 1 ½ cups of the Lucky Charms marshmallows into the dough. This will give your cookies that charming, colorful aspect. Be cautious not to crush the marshmallows too much; they should maintain their shape.
Step 7. Using a spoon, scoop out dough portions and place them onto a baking sheet lined with parchment paper. Leave space between each scoop, as the cookies will spread while baking. Aim for small mounds for a nice cookie shape.
Step 8. Sprinkle the remaining ½ cup of Lucky Charms marshmallows on top of the cookie mounds before placing them in the oven. This adds an appealing visual detail and ensures everyone knows there are marshmallows inside.
Step 9. Bake the cookies in the preheated oven, watching for them to turn light golden brown around the edges. The center may appear slightly underbaked, which is perfect since they will continue to firm up as they cool.
Step 10. Once done, remove the baking sheet from the oven and let the cookies cool on the sheet for a few minutes. This resting time helps them set before transferring them to a wire rack for total cooling.

Pro Tips for Best Results
- Make sure your butter is softened to room temperature for smoother mixing.
- Avoid overbaking; cookies should look slightly underdone in the center.
- Consider a light sprinkle of salt on top after baking to enhance the sweetness.
- Use a cookie scoop for uniform size and baking consistency.
- Keep an eye on the marshmallows, so they don’t over-toast in the oven.
Common Mistakes to Avoid
- Using cold butter: Cold butter can result in dense cookies. Always allow it to soften at room temperature for the best texture.
- Not measuring flour accurately: Too much flour can make cookies dry. Use a spoon to lift flour into a measuring cup and level it off.
- Skipping the resting period: Letting the cookies cool on the pan for a few minutes helps them set properly. If you move them too soon, they may fall apart.
- Overmixing the dough: This can result in tough cookies. Mix until just combined for the best texture.
- Baking on a warm sheet: A warm baking sheet can cause cookies to spread too much. Always ensure it’s cool before adding more dough.
- Not using parchment paper: Parchment paper helps cookies bake evenly and prevents sticking, so don’t skip this step.
Variations & Substitutions
- Consider adding chocolate chips for a different flavor twist.
- For a festive touch, try using seasonal marshmallows or sprinkles.
- If you’d like a touch more flavor, feel free to swap in brown sugar for some of the granulated sugar.
- You might substitute some of the all-purpose flour with whole wheat flour for added nutrition.
Storage & Reheating
Store any leftover cookies in an airtight container at room temperature for up to a week. If you want them to last longer, feel free to refrigerate them for better preservation. For freezing, place the cookies in a freezer-safe bag or container; they can be stored for up to three months. When you’re ready to enjoy them, let them come to room temperature or warm them briefly in the microwave to restore their soft texture.
