If you’ve ever had Crumbl’s Biscoff lava cookies, you know the magic: a soft, buttery cookie loaded with cookie butter flavor, hiding a molten cookie butter center that oozes when you break it open. And then there’s the drizzle on top, plus crushed Speculoos cookies for that crunch.
Well, I’m here to tell you this homemade version is even better. These copycat Crumbl cookie butter lava cookies are insanely easy to make with simple pantry ingredients, they cost a fraction of what you’d pay at the bakery, and the gooey lava center? Unreal.
I was honestly intimidated to try making Biscoff stuffed cookies at home because they looked so impressive. But the technique is so much simpler than you’d think, you just freeze little dollops of cookie butter and tuck them inside. That’s the whole trick!

I don’t usually comment, but these cookies were insane. They were easy, quick to make, and tasted amazing. Thanks for this! We don’t have Crumbl in our country but tried them on vacation. Kids said these were better!
Let’s Chit chat!
I’ve been developing Crumbl copycat recipes for years now, and this Biscoff lava cookie is one of the most requested dupes I’ve ever made. The trick that makes or breaks this recipe is freezing the cookie butter before stuffing it into the dough. If you skip that step, it just melts into the cookie and you lose that gorgeous lava center.
I tested this recipe with both Trader Joe’s cookie butter and Lotus Biscoff spread, and both work perfectly. The Trader Joe’s version is a tiny bit sweeter, while the Biscoff brand has a deeper spice flavor. Either way, you’re getting an incredible cookie. I also tested with and without cornstarch, keep it in! It gives these cookies that thick, soft-in-the-middle texture that makes Crumbl cookies so addicting.

What Is Cookie Butter?
Cookie butter (also called Speculoos spread or Biscoff spread) is a creamy, spreadable paste made from crushed Belgian spice cookies. It has a caramel-like sweetness with warm cinnamon and gingerbread notes. Think of it as peanut butter’s cooler, more indulgent cousin. In this recipe, cookie butter pulls double duty, it goes into the dough for flavor AND gets frozen into little dollops that become the molten lava center.
How to Make Crumbl Biscoff Lava Cookies at Home
- Line a baking sheet with parchment paper, drop individual dollops of cookie butter on it then freeze for 15-30 minutes.
- Cream the butter, cookie butter, brown sugar, and granulated sugar in a bowl.
- Add in the egg and the vanilla extract and mix again.
- Fold the dry ingredients into the wet ingredients.
- Using a large cookie scooper, scoop out the cookie dough, make a well in the center, and place a frozen dollop of cookie butter right in there.
- Fold the cookie dough over to seal then place on a parchment paper lined cookie sheet. Repeat the process and bake in the preheated oven.
- Allow the cookies to cool down then drizzle cookie butter on top, sprinkle crushed-up speculoos on top, and enjoy!
Tips for the Perfect Cookie Butter Lava Center
- Freeze the cookie butter dollops for at least 15–20 minutes. If they’re not firm, the center won’t stay as molten, it’ll just absorb into the dough or ooze out completely.
- Don’t overbake! Pull the cookies at 10 minutes even if they look slightly underdone. They’ll set up as they cool, and the center stays gooey.
- Seal the dough completely around the frozen cookie butter. Any gaps and the lava will leak out the side instead of staying in the center.
- For maximum ooze, microwave a cooled cookie for 10–15 seconds before serving. The lava center comes right back to life.
Frequently Asked Questions About These Crumbl Biscoff lava cookies – FAQ
You can store these Crumbl cookie butter lava cookies in an airtight container at room temperature for up to 4 days. You can also store them in the fridge for up to a week. I definitely recommend microwaving them for a few seconds to get the center ooey gooey again.
Absolutely! Lotus Biscoff spread and Trader Joe’s Speculoos Cookie Butter are interchangeable in this recipe. The Biscoff brand tends to have a slightly deeper spice flavor, while TJ’s is a touch sweeter. Both create an amazing lava center. Just make sure you use the smooth/creamy variety, not the crunchy one.
The big difference is the lava center! Regular Crumbl Biscoff cookies (like their white chip version) are a solid cookie butter dough with mix-ins. These lava cookies have a frozen dollop of cookie butter stuffed inside that melts during baking, creating a gooey, molten center when you bite in. It’s basically two cookie butter experiences in one cookie.
You can, but I’d keep it to about 1/3 cup so the dough can still seal properly around the frozen cookie butter center. Too many chips and the dough won’t hold together well enough to keep the lava inside. If you want a cookie butter + white chip cookie without the lava center, check out my Crumbl Biscoff White Chip Cookies recipe instead!
This usually happens for one of two reasons: either the cookie butter wasn’t frozen solid enough before stuffing, or the dough wasn’t sealed completely around it. Make sure you freeze the dollops for a full 15–20 minutes until they’re firm, and press the cookie dough edges together tightly so there are no gaps.
These cookies freeze so well. you can flash freeze them on a baking sheet for 20 minutes to allow the toppings to set then transfer them to a freezer-safe bag or an airtight container and freeze for up to 3 months.
When you are ready to enjoy them thaw at room temperature for a few hours or in the fridge overnight. My Microwave tip stands here too! Heat them up just a little bit to get them ooey gooey again.
Absolutely! Instead of making large 1/4 cup cookies divide each large cookie dough ball in half making 16 smaller cookies instead of 8 large ones.
Fill them up with 1/4 tablespoon frozen cookie butter and bake for 7 minutes instead of 10 minutes. They will look a little underdone but allow them to cool down and set.
