To successfully whip up your own batch of Crumbl Oreo Sandwich Cookies, gather the following ingredients:
- 2 large Eggs
- 7 oz Marshmallow fluff
- 3 cups All-purpose flour
- 1 1/2 tsp Baking soda
- 1 1/2 cups Brown sugar, light packed
- 1 cup Cocoa powder, black
- 1 cup Granulated sugar
- 1 cup Powdered sugar
- 1 1/4 tsp Salt
- 1 1/3 tbsp Vanilla extract
- 2 cups Oreo crumbs
- 2 tbsp Oreos, crushed
- 1 1/2 cups Unsalted butter, softened
- 1/2 cup Salted or unsalted butter, softened
Feel free to substitute if needed; for instance, coconut flour can work if you’re going gluten-free, just adjust the amount accordingly.
Step-by-step instructions

- Preheat the oven to 350°F (175°C).
- In a large bowl, cream together the unsalted and salted butter, brown sugar, granulated sugar, and powdered sugar until smooth.
- Beat in the eggs, vanilla extract, and marshmallow fluff until well combined.
- In another bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt.
- Gradually add the dry ingredients to the wet mixture, stirring until just combined.
- Gently fold in the Oreo crumbs for that signature flavor.
- Drop spoonfuls of dough onto a baking sheet, spacing them a couple of inches apart as they will spread.
- Bake for 10-12 minutes, or until the edges are set but the centers remain soft.
- Allow cookies to cool completely on a wire rack. This step ensures they maintain their structure before assembling.
- Once cooled, sandwich the cookies together with additional marshmallow fluff or frosting if you want an added touch of sweetness.
Best ways to enjoy it
Once your Crumbl Oreo Sandwich Cookies are ready, think about how to serve them. These beauties stand tall on a cookie platter, paired with a cold glass of milk for that classic combination. You can also consider serving them alongside a scoop of vanilla ice cream for a decadent dessert. For added flair, dust the sandwich cookies with powdered sugar or drizzle with chocolate for a more eye-catching presentation.
How to store
Storing your leftover cookies is straightforward. Keep them in an airtight container at room temperature for up to five days. If you want them to last longer, feel free to freeze them; just make sure to separate them with parchment paper, so they don’t stick together. When you’re ready to indulge again, simply let them thaw at room temperature or warm them slightly in the microwave.
Helpful cooking tips
- Make sure your butter is at room temperature to ensure a smooth cream when mixing the sugars.
- Don’t overmix your dough once you add the dry ingredients; this will help keep your cookies soft.
- If you want an extra chocolatey kick, consider adding chocolate chunks or chips into the dough.
- Let the cookies rest a few minutes on the baking sheet before transferring them to the wire rack; this helps them maintain their shape.
Creative twists
Feeling adventurous? Consider mixing in some crushed peppermint candies for a holiday twist or experimenting with other flavored marshmallow fluff to change up the filling. You could also use gluten-free flour if you need a dietary alternative, making these cookies accessible to everyone.
