My family loves chocolate desserts as much as any chocaholic. Chocolate lava cakes are baked in round ramekins or custard cups, and they have firm outer edges (brownie-like edges) but are gooey in the middle. That way, when you cut into them, the liquid chocolate inside spills out just like lava from a volcano. They’re really fun to eat.
Almost any time we have a special occasion, or have gone a while without eating chocolate, it’s inevitable that at least one of my children will humbly come and ask me to make chocolate lava cake. It’s a very rich dessert, which is why a small serving is enough to satisfy even the most serious chocolate lover.
After I answer some questions about the best way to reheat chocolate lava cake, I’m sharing the best recipe I’ve used to make these treats. I want to encourage you to try it! You won’t be disappointed.
How to Reheat Lava Cake and Molten Chocolate Cakes
The best way to reheat lava cake, or molten chocolate cakes, uses techniques that retain its gooey center but doesn’t overcook the cakes. With just a few tips and tricks, you can have your cake and eat it, too!
The reheating methods I’m sharing are the microwave method, stovetop method, and oven method.

Microwave Method for Reheating Lava Cake
If you want to reheat lava cake in just a few seconds, there’s nothing quicker than a microwave. And if you’re not opposed to using a microwave, it generally only takes 30 seconds or less to get the job done.
Simply put your cold lava cake in the center of the microwave on a microwave-safe plate if it’s not still in the ramekin. Then remove any lid or plastic wrap, and heat it on high power for roughly 20 to 30 seconds.
You’ll want to keep a close watch on your lava cake through the microwave window though, since some microwaves run hotter than others. As soon as you see the center of the cake puff up, that’s your queue to stop the microwave.
Be careful in removing your molten cakes and use hot pads. And even though you only heated it for a short time, let it cool slightly before serving since the extra ooey center will be piping hot.
Stovetop Method for Reheating Lava Cake
To reheat lava cake on a stove, I recommend using a small pot and adding enough water to go halfway up the ramekin. You should also set your ramekin on a wire trivet or a canning ring so that it’s not in direct contact with the heat at the bottom of the pot, which could cause your ramekin to crack.
Simply set your cold ramekin on the trivet or canning ring, remove any lid or plastic wrap, add the water (careful not to splash your leftover lava cake), and turn the heat to medium or medium-high. Watch your water closely since stove burners put out different BTUs.
When the water starts to simmer, turn the heat down to low and put a lid on your pot to trap the heat inside. You will have a perfect lava cake within a few minutes. Once you see that your leftover lava cake has a molten middle, take it off the stove and let it cool a few minutes. Be extra careful removing the ramekin from your pot.
Oven Method for Reheating Lava Cake
If you want to reheat lava cake in a conventional oven, I recommend using a deep baking sheet or casserole dish and adding enough water so that it goes halfway up the ramekin. Then bake your molten lava cakes at 350°F (180°C) until the center liquefies.
Ovens vary and the baking time will vary depending on if you’re reheating a single serving or multiple leftover lava cakes. Check your cakes after 5 minutes by testing to see if the middle is soft. Continue cooking as necessary, and carefully remove the baking sheet when your decadent chocolate lava cake is perfectly warmed through.

Ingredients

This simple recipe will make 8 servings of chocolate lava cake.
Unsalted butter – Use real butter. You’ll need 2 sticks (16 tablespoons). You can’t beat the flavor of real butter and it’s also a healthy, traditional fat to use in your kitchen.
Bittersweet chocolate – You will need 4 ounces of good quality bittersweet chocolate, chopped up. I like to use Baker’s bittersweet chocolate baking bar, but use what you prefer.
Semisweet chocolate – Use 4 ounces of good quality semisweet chocolate, chopped up. Baker’s semisweet chocolate baking bar has a great flavor and melts beautifully.
Powdered sugar – You’ll need 2 and 1/2 cups of powdered sugar that’s been sifted. I don’t like the packages in most grocery stores because they have a chalky aftertaste. Instead, I get Azure Standard’s powdered sugar.
Eggs – Use 8 eggs in this recipe. If you want a fudgier or more custard-like texture, use 4 whole eggs plus 6 egg yolks.
Vanilla extract – Use good quality vanilla extract. You’ll need 2 teaspoons.
Flour – You’ll need 1 cup of sifted all purpose flour. I’ve made this recipe with freshly milled flour a few times before, but it has a grittier texture than regular all purpose flour. So for this recipe, I recommend using just all purpose flour.
If all you have is freshly milled flour, that’s fine. Just mill your grain on the finest setting you can get and then sift it the best you can to get most of the larger pieces out if you’re sensitive to texture.
Tools You May Need

How to Make Classic Chocolate Lava Cake Recipe
The best classic chocolate lava cake recipe is made with real butter, semisweet chocolate, and bittersweet chocolate. If you need a quick dessert that will hit the chocaholic spot, this is it!
First, preheat your oven to 425°F. Then grease 8 ramekins or custard cups with some of your unsalted butter and set the ramekins on a baking sheet.

Then, add the rest of your two sticks of butter and four ounces each of semisweet chocolate and bittersweet chocolate to a large mixing bowl. The smaller the chunks, the quicker it will melt together.
I used a glass mixing bowl so you can easily see the ingredients, but you can use a stainless steel bowl or microwave-safe bowl. Just don’t use a plastic bowl.

Fill a large pot with an inch of water, turn the heat up to medium-high, and set the bowl of butter and chocolate chunks on top. This creates a double boiler.

Stir continuously until the chocolate and butter are melted.

Once the butter and chocolate have just melted, turn off the heat and carefully remove the bowl to a hot pad or kitchen towel on your counter.

Sift in 2 and 1/2 cups of powdered sugar.

Stir the powdered sugar into the melted butter and chocolate until it forms a very thick batter. Then set it aside to cool.

In a separate medium bowl or larger measuring cup, whisk 8 whole eggs (or 4 whole eggs plus 6 egg yolks) together with 2 teaspoons of good vanilla extract.
Carefully stir the egg mixture into the melted chocolate mixture.

Then add one cup of flour to your egg and melted chocolate mixture. Stir until all the flour is incorporated.

Carefully pour the lava cake batter into the eight greased ramekins. Be sure to leave a good bit of headspace at the top to give room for expansion.

Bake at 425°F for about 13 minutes until you get brownie-like edges with a molten center.
Be sure to let your lava cakes cool down for a couple minutes before serving. They will be very hot!
How to Serve These Molten Chocolate Cakes
You can invert the ramekins individually over dessert plates, and then serve alongside your favorite vanilla ice cream. If, like me, you don’t want to dirty up that many dishes, you can serve these molten chocolate cakes in their individual ramekins with a scoop of ice cream or whipped cream on top.
How to Store Molten Chocolate Cakes
To store molten chocolate cakes, wait for them to cool down to room temperature. Then you can wrap the top with plastic wrap or add a tight fitting lid and refrigerate for a later time.
I like to use ramekins with a tight fitting lid to create an airtight container, but use what you have.
Recipe Variations
Flour
Even though I have an electric grain mill, I still prefer to use all purpose flour in this recipe. In my personal experiences with this recipe, freshly ground flour has a bit of a gritty texture no matter which grain I use. It still tastes good, but it’s just not as smooth and might ruin the full molten lava cake experience if you’re sensitive to textures.
Grain-Free Chocolate Lava Cakes
If your family doesn’t handle wheat or gluten very well, you can use cassava flour in place of the regular flour 1:1.
Toppings
While vanilla ice cream and whipped cream are excellent additions to put on top or on the side of your molten lava cakes, you can also choose fresh berries or chopped nuts to top your decadent chocolate lava cake. A sprinkle of powdered sugar will make it look even better.

How to Reheat Lava Cake
- To reheat leftover lava cake, set your ramekins into a deep baking pan, add water halfway up the ramekin, and warm them in a 350℉ oven for a few minutes until the middle is soft again. You can also heat it up in the microwave for about 30 seconds, or until the center puffs up.
