Recently, me, my sister, and my brother-in-law headed up to Milwaukee for Summerfest to see Benson Boone in concert. Crumbl also released a special Moonbeam Ice Cream Cookie in collaboration with him, and it just looked so fun and over-the-top that I wanted to try it.
But… I didn’t want to risk a full dairy overload and end up with an upset stomach on the roadtrip there and back because that would have sucked so bad.
Which is why I decided to make my own version at home, something I could actually eat, pack up in a container, and enjoy in the car while we listened to Benson Boone the whole way up to Wisconsin.
And honestly? It was so good. But you might be asking, what is moonbeam ice cream?
While we don’t know for sure, Benson himself didn’t even tell us the answer at the concert (rude), we do know the cookie from Crumbl is a chilled chocolate cookie stuffed with cookies and cream pieces. It’s frosted with a big, colorful tie-dye swirl of lemon, blueberry, and marshmallow flavors, drizzled with white chocolate, and finished with more crushed cookies.
It’s meant to look and taste like ice cream, but as a giant bakery cookie.
My version is a homemade twist you can prep ahead and keep chilled for snacking whenever you want, even on a long car ride to a concert.

How to Make The Moonbeam Ice Cream Cookie 🍦
Chocolate Cookies
- Preheat oven to 350°F. Line baking sheets with parchment.
- Beat butter and sugars until light and fluffy (2–3 minutes).
- Add eggs one at a time, then vanilla.
- Whisk together flour, cocoa, baking soda, and salt.
- Slowly mix dry ingredients into wet until combined.
- Fold in the crushed Oreos.
- Scoop big balls of dough (~1/4 cup), place on your baking sheet, and gently flatten.
- Bake 10–12 minutes. Edges should look set but centers stay soft.
- Let them cool completely, then chill them in the fridge. That chilled, ice-cream-like texture is half the fun!
Marshmallow Frosting
- Beat butter until smooth.
- Add marshmallow fluff and beat until fluffy.
- Slowly mix in powdered sugar. Add milk as needed until spreadable.
- Stir in vanilla.
You want it thick but pipeable.
Divide & Flavor
- Divide frosting into three bowls.
- Bowl 1: Lemon zest + yellow food coloring.
- Bowl 2: Blueberry jam + blue food coloring.
- Bowl 3: Leave white for marshmallow.
Make the Tie-Dye Swirl
- Spread the three colors side by side on plastic wrap.
- Roll into a log and snip one end.
- Place in a piping bag with a large round tip.
- Pipe onto the cookies for that pretty swirl.
White Drizzle
- Melt white chocolate chips with coconut oil in the microwave in short bursts.
- Let it cool slightly, then drizzle over the frosted cookies.
Finish with Extra Cookies & Cream
- Crush extra Oreos and sprinkle on top.
These Moonbeam Ice Cream cookies turned out to be the perfect little treat to pack for the road. I loved having something homemade (and a little easier on my stomach) to look forward to on the way up to Summerfest. They’re big, soft, chilled, and colorful, honestly just a really fun baking project that felt like such a personal touch for the weekend.
If you try making them, I hope you love them as much as I did! Let me know how they turn out, especially if you’re planning your own concert trip or road adventure. Happy baking!
