Chewy, chocolatey cookies filled with a warm gooey center. These cookies are so decadent and fudgy, they are a chocolate lovers delight!
Crumbl Molten Lava Cookies
Molten Lava Cakes are a dessert that I absolutely love but they can be a little finicky to make- enter these COOKIES! We use a jarred hot fudge sauce so it is always perfectly melty in the middle of the cookie.
This cookie was one that was featured quite often at Crumbl Cookies back in the day but we haven’t seen it in a while! So if you are needing your Molten Lava Cookie fix, this is the recipe for you!
Ingredients in Molten Lava Cookies
- Butter- It can be salted or unsalted, but just make sure that it is salted so that it creams well with the sugar.
- Granulated Sugar
- Brown Sugar- Using the 2 types of sugar give these cookies the perfect chewy texture that we are looking for.
- Corn Syrup- This helps the final cookie to be ultra chewy.
- Flour- Just plain old all purpose flour will do.
- Dutch Processed Cocoa- I absolutely love Dutch Processed Cocoa, it is darker and richer in flavor. But if you only have regular cocoa, use what you have.
- Corn Starch
- Baking Soda
- Hot Fudge- I just use store bought hot fudge, the kind you get in the ice cream aisle. But if you are wanting to use homemade, you can use my Hot Fudge Sauce Recipe!
- Powdered Sugar- This ingredient is for dusting, it is totally optional but makes the cookies look so pretty.
How To Make Molten Lava Cookies
Start by preheating the oven to 350 degrees.
In a stand mixer, cream the butter together with the 2 types of sugar until light in color and fluffy in texture. Add in the eggs, corn syrup and vanilla and beat again until combined.
Next add in your dry ingredients, flour, cocoa powder, corn starch and salt and mix until a dough ball forms. The Dough will be soft and almost silky smooth in texture. Be careful not to overmix. Overmixing will cause your cookies to dry out.
Divide the dough into 12 equal parts. I like to use a half cup to scoop out the dough. Each dough ball should be slightly less than 1/2 cup.
Roll the dough into a ball and use your thumb to create a pocket in the dough ball. Spoon about a half tablespoon of hot fudge into the hole of the dough ball and pinch the cookie dough closed around the fudge.
Flatten the dough ball with your hands until the dough kind of resembles a hockey puck. Repeat with the remaining cookie dough.
Bake at 350 degrees for 15-17 minutes. The tops of the cookies will start to crack and crinkle, and you will know they are done when the tops of the cookies no longer looks wet.
Allow the cookies to cool on the pan for an additional 15 minutes.
Dust with powdered sugar and serve warm.
How to make Smaller Cookies
You can definitely make smaller cookies and still stuff them. You’ll just need to use a smaller amount of cookie dough, a smaller amount of hot fudge and a shorter cook time. Watch for the indicators of the cookies spreading slightly, puffing up and the tops starting to crackle to know when to pull them out of the oven.
Storing your cookies
Store your cookies in the fridge in and air tight container for up to 1 week. You can also freeze them for up to 3 months.
How to Reheat your Cookies
Just pop your cookie into the microwave for about 10 seconds to get that melty fudge center back after storing them!

Karli Bitner says
Hi Elle! Keep your eyes peeled for the Aggie Blue Mint coming soon! 🙂
I made these earlier this week, and may have not used enough fudge in the center. You could see it there, but very very little. Almost like it got baked into the cookie? Would love to see you do a tik tok on how you make these. I follow you 🖤
Amy F says
These were absolutely amazing! I’ve never had Crumbl so I can’t compare the taste but my family does love cookies and these were a huge hit!!
Hi Karli! Do you need to chill the cookie dough before baking? Also what would happen to the cookie if I didn’t add the corn syrup?
Going to try these this weekend! Have a friend that is a chocolate lover and it will be a hit. Thanks for the recipe
Karli Bitner says
No need to chill the dough- the corn syrup just helps keep the fudgey texture.
Deanna Cleman says
Hello, I love the crumbl cookies. Do you have to use baking powder? You want them thick and soft? Just curious
Karli Bitner says
Yes, the baking powder does help them stay soft and it aids as a leavening agent so they don’t go super flat.
Very tasty and wonderful fudge in the middle. Decadent. Question, one of the commenters mentioned the use of baking powder but the recipe doesn’t call for it. Did you change the recipe? My cookies were good but very flat. I also wondered about chilling the dough a little to prevent this. Thanks for the recipe!
great recipe. Just thought I’d share a useful tip if you don’t have fudge sauce on hand. I substituted with home made chocolate ganache. I combined chocolate chips, heavy cream and vanilla, then refrigerated until firm. once firm I inserted a spoonful into the cookie dough ball.
Barb Freund says
Best cookie EVER! Better than the Crumbl version this is copying. We love all her cookies but this one is extraordinary. Thx for the great recipe!
