The Crumbl Moonbeam Cookie is a chilled, limited-time cookie with a thick chocolate base topped with a lemon-berry buttercream swirl. It usually finishes with a soft vanilla/marshmallow note, plus a white-chocolate drizzle and a light cookie crumb for texture. The bite is fudgy and rich from the base, lifted by the bright citrus-berry frosting so it tastes bold but not heavy. It’s designed to be eaten cold for the cleanest flavor and color swirl.
What is the Crumbl Moonbeam Cookie
The Crumbl Moonbeam Cookie is a chilled, limited-time flavor inspired by Benson Boone’s “Moonbeam” dessert theme that Crumbl tapped into during a buzzy run this year. The core builds around a rich chocolate cookie base with a bright, fruity frosting vibe that leans lemon and berry, often finished with a creamy or marshmallowy note. Media tastings called out that lemon-berry profile clearly, which explains why the cookie tastes lighter than a typical chocolate bomb and why it photographs so well for socials. Elite Daily
Crumbl rotates flavors every week, so Moonbeam appears during specific menu windows and sometimes gets an encore if demand stays high. The easiest way to confirm if your store has it is to check the live menu in the Crumbl app or the official site before you head out.
Flavor & texture review
I like to taste Crumbl cookies both chilled and closer to room temp because the experience can change a lot. With the Crumbl Moonbeam Cookie, chilled is the move. The chocolate base stays dense and fudgy, and the frosting keeps a clean citrus-berry edge instead of melting into a sugary blur. The fruity top note balances the base so the cookie doesn’t feel heavy after a few bites, and a soft vanilla or marshmallow finish rounds it out. That balance is what sets Moonbeam apart from the usual chocolate-forward drops that rely on pure richness. Media tastings described those same lemon and berry vibes, which matched my experience.
If your store finishes Moonbeam with a decorative drizzle or crumb, expect a little extra sweetness on top and a tiny bit of crunch against the soft crumb. I recommend storing leftovers chilled and eating within 24 hours for the best texture. If you prefer softer frosting, let a portion sit out for 10 to 15 minutes, then taste again. It’s almost like two cookies in one.
Ingredients & Common Allergens Overview
When I look at the Crumbl Moonbeam Cookie, I expect a rich chocolate base and a bright, citrus-berry style frosting. That combo usually means wheat flour, butter, sugar, cocoa powder, eggs, and leavening in the cookie. The frosting typically leans cream-based with lemon and berry flavor, sometimes with a vanilla or marshmallow finish. Many Crumbl style cookies include toppings like cookie crumbs or a white-chocolate drizzle for contrast.
Allergen watch for this flavor usually includes wheat, dairy, and eggs. Some stores rotate toppings, and anything with chocolate or crumb mix can introduce soy. If your store uses a crumble topping or sandwich cookie crumb, there’s always a chance of trace nuts from shared equipment. I always check the live menu in the app for my exact store before I buy, then tap into the nutrition and allergen panel to confirm.
Calories & Nutrition
Crumbl is famous for jumbo cookies, so the calories stack up fast. The number swings by location and whether you split the cookie into portions. I treat a quarter or a half cookie as a serving when I want the flavor without going overboard. If you care about precise numbers, open the Crumbl app, set your nearest store, and check the Moonbeam panel. You’ll see calories per serving, allergen flags, and sometimes a detailed ingredient list. I use that as my source of truth since it reflects the exact formula and supplier your bakery uses.

- 5–6 tablespoons milk or cream
- 2 teaspoons vanilla extract

Crumbl Moonbeam Cookie Step-by-Step Instructions
Bake the Chocolate Cookies
- Beat the softened butter and sugar on medium-high until fluffy.
- Add eggs and vanilla; mix until smooth. Scrape the bowl and mix briefly again.
- In a separate bowl, whisk flour, cocoa, cornstarch, baking soda, and salt.
- With the mixer on low, add the dry mix gradually. Scrape the bowl; mix just until fully combined.
- Preheat oven to 350°F. Scoop large mounds of dough (about ¼–⅓ cup each) onto a sheet pan. Freeze the pan for at least 20 minutes so the dough sets.
- Bake 9–11 minutes on parchment or a silicone mat. Look for the tops to lose their shine and the edges to set while the centers stay soft. If the domes are tall, gently press with a spatula to level.
- Cool on the pan 10–20 minutes so the cookies firm up, then chill the pan in the fridge (or freezer) at least 20 minutes before frosting.
Make the Lemon-Berry Buttercream
- Beat butter with a paddle until smooth.
- Add about 1 cup powdered sugar, then a splash of milk; beat high until silky. Repeat, alternating sugar and milk, until all the sugar is in and the frosting is smooth. Beat in vanilla, lemon extract, raspberry, and strawberry flavorings.
- Divide frosting into 3 bowls. Tint one purple, one blue, one yellow.
- To frost, add a small dollop of each color on a chilled cookie and swirl gently together; don’t overmix or you’ll lose the tie-dye effect.
- Drizzle with melted white chocolate and finish with crushed cookies. Keep cookies chilled until serving.
Notes & Tips
- Choosing cocoa: Dutch-process gives darker color and a smoother chocolate flavor; natural cocoa is brighter and more acidic. Either works in cookies like this where baking soda is modest and flavor leads the way.
- Silky buttercream: Most frosting issues are temperature issues. If it’s soupy, chill briefly then re-whip; if it’s curdled, warm the bowl slightly and whip. Keep it in the 69–75°F range for the smoothest swirl.
Tip: For the same creamy swirl you see here, follow the Moonbeam Ice Cream Recipe and use it as your topping.
Mistakes to Avoid
- Skipping the chill. The freezer step keeps these jumbo cookies thick with soft centers.
- Overbaking the shine away. Pull when the tops just turn matte; they finish setting on the pan.
- Over-swirling the colors. A couple of passes is enough; too much mixing turns the frosting gray.
- Hot cookies + buttercream. Always frost chilled cookies or the tie-dye slides.
Serving the Crumbl Moonbeam Cookie
I serve these chilled for a clean citrus-berry pop against the chocolate base. Store in an airtight container in the fridge up to 48 hours. For a softer bite, let a cookie sit at room temp 10–15 minutes before eating.

PAA Quick Answers
What is the Crumbl Moonbeam Cookie made of
A dense chocolate cookie base topped with a lemon-berry style frosting, sometimes finished with a light vanilla or marshmallow note and a decorative crumb or drizzle. Ingredients vary by store, so I always confirm in the app.
Is the Moonbeam Cookie coming back to Crumbl
Crumbl runs a weekly rotation. Popular flavors sometimes return for encore weeks. I check Sunday night or Monday morning in the app to see if Moonbeam is back near me.
Which cocoa powder style is best for rich cookies
For this cookie, I like Dutch-process cocoa. It gives a darker color and smoother chocolate flavor that pairs nicely with the bright frosting.
Air fryer size that fits cookie sheets
Most basket models handle two to three jumbo cookies at a time on a cut piece of parchment. If you want a true sheet fit, a larger oven-style air fryer works better. Leave space around each dough mound so air can circulate.
Are silicone baking mats worth it for cookies
Yes for repeat baking and even spread. Mats promote gentle browning and easy release. If you prefer crisper bottoms, parchment can give a touch more edge color.
