These Crumbl molten lava cookies are soft, rich chocolate cookies with a gooey molten center that stays melty long after baking. Theyโ€™re thick, chewy, deeply chocolatey, and filled with a bittersweet chocolate lava sauce that creates that classic molten lava cake effect, but in cookie form.

If you love indulgent chocolate desserts, this recipe delivers big bakery-style results without complicated steps. The dough is made with simple pantry staples, and the molten center comes from a frozen chocolate fudge filling that melts perfectly as the cookies bake.

Iโ€™ve tested this recipe multiple times to get the texture just right, soft and fudgy on the outside, molten and glossy in the center. Whether youโ€™re baking for Valentineโ€™s Day, the holidays, or a weeknight chocolate craving, these cookies are guaranteed to impress.

Let’s Chit Chat!

Iโ€™ve wanted to recreate these Crumbl molten lava cookies for a long time, but I didnโ€™t want to rush it. A cookie like this only works if the texture is right, soft and rich on the outside, with a truly gooey center that stays molten after baking.

I tested this recipe multiple times, adjusting the dough thickness, bake time, and filling so the chocolate actually melts instead of disappearing into the cookie. The result is a molten lava cookie that feels just as indulgent as the real thing, but even better when itโ€™s warm straight from your own oven. If you love rich chocolate desserts and cookies with dramatic centers, this one is absolutely worth making.

Why You Can Trust This Recipe

I specialize in recreating bakery-style and Crumbl copycat cookies, and chocolate-based recipes are some of the most tested on my site. This molten lava cookie recipe went through multiple rounds of testing to ensure:

  • The cookie stays soft and thick, not cakey
  • The center stays molten, not absorbed into the dough
  • The cookies reheat beautifully without drying out

I tested different chocolate fillings, bake times, and dough thicknesses before landing on this version. Using frozen dollops of thick chocolate fudge sauce is the key technique that keeps the center gooey while the cookie bakes evenly around it.

Frequently asked questions – FAQ

Can I freeze Molten lava cookies?

You definitely can! You can store these cookies in an air-tight container for up to 2 months. Once ready to enjoy, let it thaw on the countertop for a few hours or just microwave it for a few seconds to warm up the cookie again.

Why didnโ€™t my cookies have a molten center?

This usually happens if the chocolate filling wasnโ€™t frozen long enough or if the cookies were baked too long. Make sure the fudge sauce is fully frozen and slightly underbake the cookies.

What’s the best chocolate lava sauce to use?

When it comes to chocolate lava sauce, the better the quality, the better your cookies will taste that’s why I strongly suggest using the Stonewall kitchen bittersweet chocolate sauce. It is not overly sweetened and it is so luscious and smooth. I think it has the best mouthfeel anyone would ever look for in a molten lava cookie!

How to make smaller molten lava cookies?

If you want to make smaller cookies, instead of going with 6 large cookies, make 12 smaller ones. Fill them with about 1 teaspoon of hot fudge sauce the same way you would the larger ones and bake in the preheated oven for 8 minutes.

Can I substitute the lava sauce with something else?

Absolutely! You could try Nutella or creamy peanut butter for a fun and tasty variation!

Can I make these ahead of time for Valentineโ€™s Day?

Yes! Bake them up to 2 days ahead and reheat in the microwave for 10โ€“15 seconds before serving to bring back the molten center.

Do these cookies spread a lot?

No, this dough is designed to stay thick. Lightly flattening before baking helps them bake evenly without spreading too much.

Can I use chocolate chips instead of fudge sauce?

Chocolate chips wonโ€™t create the same molten effect. A thick chocolate fudge or lava-style sauce works best.

How do I serve these for a special occasion?

Dust with powdered sugar, serve warm, and pair with vanilla ice cream or whipped cream for a molten lava cake-style dessert.

Notes

Hot fudge sauce notes:ย If your fudge sauce is too runny keep it in the fridge until you’re ready to scoop it out to freeze it. Some hot fudge sauces don’t freeze, in that case, you can flatten the cookie in between the palm of your hand, and gently press your fingers (of the hand you’re holding the cookie dough with) upwards to make a well in the center. Fill that with the hot fudge sauce and gently fold in the edges over it sealing it well.ย

    Could you use Nutella instead of fudge sauce?

    1. Chahinez says:

      Yes, I think that would be delicious actually!

  2. Ethan says:

    5 stars
    My mother and I baked these cookies together following the tripled recipe. Said it would yield 18 cookies, but… ended up with 34 somehow! I’m not complaining though. They turned out great and we have more than enough to share.

    1. Chahinez says:

      I am glad you enjoyed them! Even if it was more than you originally wanted lol

  3. D says:

    Hello Chahinez, can I use a chocolate spread instead of a sauce. Also will it last two weeks in an airtight container?

    1. Chahinez says:

      Hi Rhea! You could use a thick chocolate spread, but it may not give the same molten effect as hot fudge. For best texture, use thick hot fudge. As for storage, I wouldnโ€™t keep them for 2 weeks at room temperature, theyโ€™re best eaten within 4 days, or store in the fridge for up to 7 days.

  4. Leslie says:

    Hi, do you think the dough could be made and filled with the fudge, then refrigerated or frozen until ready to bake at later time?

    1. Chahinez says:

      Yes! You can make and fill the dough ahead, then refrigerate for up to 24 hours or freeze for up to 2 months. Bake straight from the fridge or freezer, just add a minute or two to the bake time.
