Ingredients
- Unsalted Butter – incorporated into the dough cold for thicker, fluffier cookies.
- Brown Sugar and Granulated Sugar – both sugars add sweetness while the molasses content in brown sugar makes the cookies more moist and chewy.
- Eggs – bind the ingredients together so the cookies can hold their shape.
- Vanilla Extract – adds flavor depth.
- All-Purpose Flour – gives the cookies their structure.
- Instant Vanilla Pudding Mix – provides the cookies with additional flavor and also makes them more moist and chewy.
- Salt – cuts the sweetness.
- Baking Powder and Baking Soda – makes the cookies extra light and fluffy.
- Lucky Charms Cereal – the cereal AND the marshmallows!
- White Chocolate Chips – the creamy sweetness of white chocolate chips pairs perfectly with the lucky charms cereal.
How to make
- Place butter, brown sugar, and granulated sugar into the bowl of your stand mixer then beat until light and fluffy. Scrape down the sides then beat in eggs and vanilla until combined.

- Add in flour, instant pudding, salt, baking powder, and baking soda then beat until fully incorporated.

- Mix in cereal and white chocolate chips.

- Use a large cookie scoop to portion the mixture out onto 4 baking sheets lined with silicone mats (you should have 32 total dough balls—8 on each sheet.)

- Chill in the fridge for 30 minutes (optional) then bake at 350ºF for 15 minutes. Cool slightly before transferring to a wire cooling rack to cool completely before serving.

Do you need to chill the dough?
Not necessarily but I do recommend taking the extra step.The colder the dough is the thicker and fluffier your cookies will be!
Do you use just lucky charms marshmallows?
No! You can just scoop the Lucky Charms cereal straight out of the box and incorporate that into the dough—cereal pieces and all!
If you would prefer to just use the marshmallows, you can definitely pick them out of the cereal but it will take a whole heck of a lot longer.
Can you use normal marshmallows?
No. Lucky Charms marshmallows aren’t nearly as soft and gooey as regular marshmallows. Using regular marshmallows will completely change the makeup and texture of the cookies.

How to store
Leftover lucky charms cookies will last in an airtight container at room temperature for up to 1 week, in the fridge for up to 2 weeks, or in the freezer for up to 3 months.
To enjoy again, serve from the fridge, at room temp, or microwave to warm.
