The downside to ordering these is that they are almost always out of stock because of the popularity of their Crumbl molten lava cookies. So, I decided to re-create the cookies myself.

I’ve been spending weeks developing the ultimate molten lava cookie with a hot fudge sauce and delicious gooey center. It’s taken some time, but if I must say so myself, it came out even better than expected!

Now, you can have chocolate lava cookies whenever you want. And surprisingly, once these cookies cool, you can freeze them for months without compromising their chocolate fudge texture.

My hot fudge chocolate lava cookies are also incredibly versatile in how you can use them – other than indulging in them as is, of course!

You can serve them with some vanilla ice cream, dust them with powdered sugar or cocoa powder, and cover them with a chocolate ganache and sprinkles for a themed finish.

This is the ultimate cookie recipe for any chocolate lover and those obsessed with Crumbl molten lava cookies. Give them a shot and share your thoughts with me!

The chocolate lava cake cookie dough contains a couple of basic cookie ingredients.

You will need some unsalted butter, light brown sugar, white granulated sugar, eggs, corn syrup, vanilla extract, all-purpose flour, cocoa powder, cornstarch, baking soda, and salt. You will also need some hot fudge sauce.

While this seems like a lot, trust me, all of these ingredients help achieve the molten lava cake texture.

Make sure you are using unsalted butter. If you only have salted butter on hand, remove the salt from the recipe.

Light Brown Sugar & White Sugar

It’s also essential that you use light brown sugar AND white granulated sugar. This adds a good balance of caramelized flavors and a sticky molten lava cookie consistency. If you only use brown sugar, it will make the cookies too tacky.

Do NOT substitute granulated sugar with powdered sugar. Instead, use caster sugar if you really have to.

Corn Syrup

If you cannot find corn syrup, the best alternative is something like agave nectar. You don’t want a substitute that overpowers the deep chocolate flavor or your copycat Crumbl molten lava cookies.

Dutch Processed Cocoa Powder

Furthermore, make sure you use unsweetened cocoa powder, aka Dutch process cocoa powder. This type of cocoa powder helps balance the super sweet flavors of the cookie dough and fudge sauce.

Baking Soda

Baking soda is what gives these chocolate cookies their chewy, coarse texture. You cannot substitute it with baking powder (they are fundamentally different), and you cannot leave it out!

If you cannot find baking soda, add three times the amount of baking powder. Keep in mind that baking powder won’t give the same texture to the cookies as baking soda does.

Hot Fudge Sauce

You can use any store-bought hot fudge sauce you like. Chocolate lovers prefer a chocolate fudge sauce instead. At the end of the day, it’s entirely up to your vision of a molten lava cookie.

Chocolate Hot Fudge sauce is also good for Churros.

How To Make Vegan Molten Lava Cookies With Hot Fudge

This kind of depends on your definition of vegan.

A basic recipe change would include substituting the butter with a plant-based alternative (even margarine), replacing the eggs with a vegan egg alternative (like flaxseed or chia eggs), and checking that your sauce is vegan on the packaging.

The rest of the ingredients should all be vegan.

Now, if you follow an extremely strict vegan diet, you may also want to check whether the sugar, all-purpose flour, baking soda, and Dutch process cocoa powder are vegan as well.

Some of these products are processed with animal ingredients, technically not making them vegan.

How to Store Your Molten Lava Cookies With Chocolate Fudge Sauce

The best way to store your molten lava cookies is before you dust with powdered sugar. The powdered sugar will dissolve when stored in an airtight container on a moist cookie filled with hot fudge sauce. It’s better to reheat the cookies before serving and then dust with powdered sugar.

To store a molten lava cookie, simply place it in an airtight container. Place some parchment paper between the cookies to prevent them from sticking to each other. If you lack parchment paper, wax paper can be a suitable alternative.

Expert Tips To Make The Most Delicious Chocolate Lava Cookies

  • When you are creaming your sugar and butter mixture, keep mixing until the butter becomes light and fluffy. This will help prevent dense cookie dough and ultimately, molten lava cookies.

  • Make sure to gently fold in your flour mixture to avoid deflating the fluffy consistency of the butter and egg mixture. Again, this step is crucial to avoid dense molten lava cookies and keep the chocolate lava consistency gooey.

  • It’s also not a bad idea to incorporate some chocolate chips into the cookie dough. They will add an even more decadent melty finish to your chocolate cookie. Choose between semi-sweet chocolate chips or dark chocolate chips.

  • If your cookie dough starts looking very oily, it’s too hot to work with at room temperature. In this case, place it on some parchment paper, cover it with plastic wrap, and place it in the fridge to firm up a little. if your cookie dough is too warm, it will spread in the oven a lot, resulting in thin, crisp cookies, not thick gooey ones.

  • Ensure that you freeze the chocolate fudge or hot fudge sauce BEFORE adding them to the cookie dough. This makes the sticky sauce easier to handle and helps it spread more slowly during baking. If you use a room-temperature sauce, the molten lava cookies won’t hold their shape very well.

  • Baking Sheet
  • Parchment Paper
  • Hand Mixer
  • 2-inch scoop


For Cookie Dough

  • 1 cup Unsalted Butter (softened to room temperature)
  • 1 ¼ cup Packed Brown Sugar
  • ½ cup White Granulated Sugar
  • 2 Large Eggs (room temperature)
  • 1 Tbsp Corn Syrup
  • 2 tsp Pure Vanilla Extract
  • 2 ½ cups All-Purpose Flour (sifted)
  • 1 cup Unsweetened Cocoa Powder (sifted)
  • 2 tsp Cornstarch
  • 1 ½ tsp Baking Soda
  • 1 tsp Salt

For Filling and Topping

  • Cold Hot Fudge Sauce
  • ¼ cup Powdered Sugar (for sifting)


Prepare the Cookie Dough:

  • Start by preheating your oven to 350ºF (180ºC) and lining a baking sheet with parchment paper.
  • In a large mixing bowl, blend softened unsalted butter, packed brown sugar, and white granulated sugar until the mixture becomes light and fluffy.
  • Then add eggs, one at a time, mixing until well incorporated after each addition. Blend in corn syrup and vanilla extract until the mixture is smooth and homogenous.
  • Next, sift in all-purpose flour, cocoa powder, cornstarch, baking soda, and salt. Carefully fold them into the wet mixture, avoiding overmixing, until a thick, rich chocolate dough forms.

Form and Fill the Cookies:

  • Using a 2-inch scoop, allocate scoops of dough on the prepared baking sheet, ensuring they are spaced about 2 inches apart.
  • Create wells in each dough scoop, using the backside of the scooper and molding the sides gently to achieve a deeper, rounded shape.
  • Fill the wells with the frozen hot fudge sauce, using a teaspoon and filling about ¾ of the way full.
  • Seal the cookies; pinch the dough over the top of the filling, adding extra dough if needed, to ensure the hot fudge sauce is completely encased.

Baking and Finalizing:

  • Place the cookies in the preheated oven, and bake for 12-14 minutes or until the cookies are just set but still soft in the middle.
  • Once out of the oven, allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.
  • Sift powdered sugar over the cookies while they’re still warm.

Serving Suggestion

  • Relish these warm Molten Lava Cookies with their gooey center along with a cold glass of milk or a scoop of your favorite ice cream for an exquisite dessert experience!
