A Sweet Memory Behind the Cookie
Hi there! I’m Emma, the heart and soul behind easymealstodo.com. From a young age, my kitchen was my playground. But it wasn’t until I tried the Crumbl Mallow Sandwich Cookie that I truly fell in love with recreating bakery-style cookies. I had picked it up on a whim for a cozy movie night, and one bite later, I knew I had to make it part of my recipe collection.
That first taste transported me to simpler times—like roasting marshmallows by a fire, but with the sophistication of a gourmet dessert. I wanted to capture that feeling and share it with others. After testing, tweaking, and eating more cookies than I care to admit, this copycat recipe was born.
It’s now a go-to in our home for birthdays, holidays, and when nothing but a sweet treat will do. Like many of my favorite Crumbl copycat recipes, this one’s easy enough to whip up on a lazy afternoon, but impressive enough to steal the show at a dessert table.
What Makes Crumbl Mallow Sandwich Cookies So Special?
The Crumbl Mallow Sandwich Cookie is all about texture. The outer layers are made from soft sugar cookies—thick, buttery, and slightly chewy. In between, a marshmallow filling adds the right amount of sweetness and fluff. When you bite into it, you get softness, chewiness, and a cloud-like center all in one.
The appeal is similar to frosted cookies but with a twist. Instead of being topped, the frosting is hidden inside. This format makes them portable, giftable, and much easier to serve during events. You can customize them for special occasions, especially Valentine’s snacks or holiday-themed dessert platters.
And for fans of marshmallow cookies, this is the ultimate upgrade—think s’mores without the mess, whipped shortbread with an airy surprise, and sugar cookies with attitude.
Ingredients You’ll Need
Here’s a simple breakdown of what goes into this Crumbl copycat. You likely have most of these on hand already.
| Ingredient | Purpose |
|---|---|
| All-purpose flour | Provides the base and structure for the cookies |
| Cornstarch | Helps create that soft, tender bite |
| Baking soda & baking powder | Gives lift and balances texture |
| Butter (unsalted) | Adds rich flavor and a chewy finish |
| Granulated sugar | For sweetness and slight crisp at the edges |
| Brown sugar | Adds moisture and a hint of caramel flavor |
| Eggs | Binds the ingredients and enriches the dough |
| Vanilla extract | Boosts overall flavor profile |
| Marshmallow fluff | The gooey center that mimics the Crumbl style |
| Powdered sugar | Stabilizes the marshmallow and thickens it |
If you enjoy baking Crumbl peanut butter cookies or their classic chocolate chip copycat, you’ll find the technique here comfortingly familiar—but the filling takes it to another level.
Step-by-Step Instructions
Let’s walk through the full process to create that bakery-style perfection at home. Make sure ingredients are at room temperature for the best results.
1. Cream the Butter and Sugars
Start by beating the butter with granulated and brown sugars. This step is key. It incorporates air and creates that light, chewy texture. Mix for 2-3 minutes until fluffy.
2. Add Eggs and Vanilla
Once the butter mixture is light, add in the eggs and vanilla. Beat again until smooth.
3. Combine Dry Ingredients
In a separate bowl, whisk together the flour, cornstarch, baking soda, baking powder, and salt. Slowly add the dry mix to the wet mixture, stirring just until combined. Do not overmix—this keeps the cookies soft.
4. Chill the Dough
Chilling the dough for at least 30 minutes helps prevent excessive spreading. For thick Crumbl-style cookies, this step is non-negotiable.
5. Scoop and Flatten
Use a cookie scoop to portion dough onto a baking sheet. Slightly flatten each one with the bottom of a cup. You want them thick but not domed.
6. Bake at 350°F
Bake for 10–11 minutes or until the edges are set but centers are still soft. They will continue cooking on the pan once removed. Let them cool completely.
7. Make the Filling
Mix marshmallow fluff with powdered sugar until smooth and slightly thickened. This helps it hold its shape when sandwiched.
8. Assemble the Cookies
Pipe or spoon the filling onto half the cookies. Top with the remaining halves and press gently. Let them set for 10–15 minutes.
Now you’ve got gourmet cookie recipes worthy of a bakery case.
Tips for Success
To master these marshmallow cookies, keep these tips in mind:
- Use room temperature butter for better creaming and even mixing.
- Don’t skip chilling the dough—this controls spread and maintains thickness.
- Sift powdered sugar into the filling to avoid lumps.
- Pipe filling in a swirl pattern to avoid overflow.
- Store unfilled cookies in the freezer and assemble fresh for events.
If you’re looking for easy desserts with few ingredients, this recipe fits the bill while delivering a fancy finish.
