Ingredients

Lucky Charms Cookies

1 box Vanilla Cake Mix {15.25 ounces}
2 tablespoons corn starch
¾ cup all purpose flour
½ cup butter {softened}
½ cup butter flavored Crisco
3 eggs
1 cup Lucky Charms marshmallows

Cereal Milk Frosting

1 cup Lucky Charms cereal
½ cup heavy cream
½ cup butter {softened}
2-2 ¼ cups powdered sugar

Instructions

Lucky Charms Cookies

Preheat the oven to 350°.
Combine the vanilla cake mix, corn starch and flour in a mixing bowl. Whisk to combine. Add the butter, butter flavored Crisco and eggs to the flour mixture and mix using an electric mixer until everything is incorporated and thick. Add the Lucky Charms marshmallows to the cookie dough and mix in by hand until they are evenly incorporated.
Using a ¼ or ⅓ measuring cup, scoop cookies into your hand and form them into discs. Place the cookie dough onto a silicone mat {or parchment} lined cookie sheet 6 at a time.
Bake for 10-12 minutes, remove from the oven and let cool on the cookie sheet. Repeat until all of the dough is baked.

Cereal Milk Frosting

While the cookies are cooling, pour the heavy cream over the Lucky Charms cereal and allow it to sit for 20-25 minutes. After the cereal has steeped in the heavy cream, drain the heavy cream from the cereal.
In a mixing bowl, add the butter and beat for a minute or until it is light and fluffy. Add the powdered sugar and cereal milk to the butter and continue to mix until it is a thick consistency. Note: If the frosting is too thick, add a teaspoon of milk at a time until you get the right texture.
Divide the frosting between the 12 cookies and spread out using the back of a spoon {or an off-set spatula}. Top with additional Lucky Charms cereal.
Store the Lucky Charms cookies in an airtight container in the refrigerator for up to 4 days.

Notes

Add a 1/2 cup of white chocolate chips to the cookie dough with the marshmallows. This will give you an extra flavor and texture.
If you prefer smaller cookies, use a medium cookie scoop and bake the cookies for 8-10 minutes. You should get between 20 & 22 cookies.
Don't over bake the cookies. The difference between a really well baked cookie and a hard hockey puck is only a minute or two.
Only allow the cereal to steep in the heavy cream for 20-25 minutes. If you do it longer than that the cereal will absorb a lot of the liquid.
Wait until the cookies are completely cooled before frosting. If you frost them while they are warm the frosting will melt.
