Get It NowMy Keto Lava Cake Recipe Is Perfect For Date Night
Say hello to one of my favorite keto desserts for two: keto lava cake! It’s rich, fudgy, and melts in the center — just like a classic molten lava cake, but totally sugar-free and low carb. I first made it for my husband and me on Valentine’s Day, and we’ve been hooked ever since. It’s easy to make, doesn’t need a ton of ingredients, and always feels a little bit romantic. Here’s why this one stands out:
- Rich chocolate molten center – That gooey middle is everything! I skip the cocoa powder and use real sugar-free dark chocolate for a deeper flavor and meltier texture. See my tips below for getting the center just right!
- Better-for-you ingredients – No sugar, no white flour. Just almond flour, Besti, and clean dark chocolate, with only 4.8g net carbs per cake.
- Fast, no-fuss prep – A lot of lava cake recipes have you chill the batter or wrap ramekins in plastic wrap… but not this one. You only need 6 simple ingredients and about 20 minutes, start to finish. No fridge time, no fuss.
- Perfect for two – I love making it for date nights or anniversaries, but it’s easy to scale up if you’re serving more. And when I’m feeling extra fancy, I’ll top it with keto vanilla ice cream, sugar-free caramel, or fresh raspberries.
Grab your ramekins and make it with me!
Ingredients & Substitutions
Here I explain the best ingredients for my keto chocolate lava cake recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Dark Chocolate Squares – I always use sugar-free dark chocolate here because it gives the richest flavor, but sugar-free chocolate chips work just as well. Honestly, any chocolate that fits your macros will do the trick
- Besti Powdered Monk Fruit Allulose Blend – This is my go-to sweetener for lava cake. It blends right into the batter (no gritty texture!) and helps keep the outside soft and cake-like. I don’t recommend swapping for erythritol or other sugar alcohols. I tried it once and the cake came out grainy.
- Wholesome Yum Blanched Almond Flour – The fine texture keeps this cake moist and fluffy instead of dense, and it’s what gives keto lava cake its cake-like structure. You could try swapping 1 teaspoon of coconut flour for the 1 tablespoon of almond flour, but I haven’t fully tested it. If you do, let me know how it turns out!
- Butter – I use unsalted, grass-fed butter so I can control the salt and get the best flavor. Any fresh, good-quality butter will work here.
- Eggs – You’ll need two eggs: one whole and one yolk. I like to bring them to room temp so they blend smoothly.
- Sea Salt
How To Make Keto Lava Cake
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Melt the chocolate. Set up a double boiler with a bowl over simmering water, add the butter and chocolate, and stir until smooth.
- Whip the eggs. In another bowl, beat the egg, yolk, sweetener, and a pinch of salt until they’re light and fluffy.
- Mix it all together. Pour in the melted chocolate, add the almond flour, and mix until combined.
- Fill the ramekins. Divide the batter, bake until the edges look set but the centers are still a little soft.
- Flip and release. Let them rest for a moment, then run a knife around the edge and invert onto plates. A few taps usually does the trick.
- Dust with sweetener. I like to dust my keto lava cake with extra powdered sweetener before serving.
My Recipe Tips
- Grease the ramekins well. These little cakes love to stick if you miss a spot, so don’t be shy with the butter. I make sure to coat the bottom and sides really well before filling them.
- Chocolate can seize if it overheats or if even a tiny bit of water gets in the bowl, so be sure it’s completely dry. I like to melt mine in a homemade double boiler with a bowl set over a pan because it keeps the heat gentle and the chocolate silky smooth. And if it does seize, a splash of heavy cream or butter usually brings it back.
- Sometimes I add just a splash of vanilla extract to the batter for extra flavor, but it’s not required. It’s one of those fun little tweaks if you like experimenting.
- Don’t overbake. I’ve overcooked plenty of keto lava cakes before figuring it out! The edges should look set, but the center should still look soft and wobbly when you gently jiggle the ramekin. If the middle looks firm like the rest of the cake, it’s already gone too far.
- Powdered Besti melts into the warm center if you add it too soon, so I always dust it on right before serving. I use this sugar duster to give it that pretty, elegant finish.
- Can I make lava cake in the microwave? You won’t get the same gooey results as baking, but there’s a faster option. Try my keto chocolate mug cake instead and tuck a few chocolate squares in the center for a quick fix.

Instructions

-
Preheat the oven to 450 degrees F (232 degrees C). Generously grease two 6-ounce ramekins with butter. Place the ramekins on a small baking sheet.
-
To set up a double boiler, bring water to a simmer in a small saucepan. Place a glass or stainless steel bowl on top. Add the butter and chocolate. Heat for 3-4 minutes, stirring occasionally, until melted. Be careful not to overheat, or the chocolate will seize.
-
Meanwhile, in a medium bowl, use a hand mixer to beat the eggs, egg yolks, Besti, and sea salt at high speed for about 1 minute, until light yellow.
-
Add the melted chocolate and almond flour to the bowl with the eggs and beat immediately, until combined.
-
Divide the batter among the two ramekins. Bake for 6-7 minutes, until the edges are set and an area of about 1-1.5 inches in diameter in the center is still just slightly jiggly.
-
Remove ramekins from the oven and let them sit for 1 minute. Run a knife around the edges to loosen. Place an upside down plate over each ramekin and using an oven mitt, carefully flip over to invert the cake onto the plate. Let the ramekin sit upside down for 30 seconds. Then, tap the ramekin against the plate several times to release and lift the ramekin.
-
Serve immediately, dusting with more powdered Besti if desired.

Maya’s Recipe Notes
Serving size: 1 lava cake
- Tips: Check out my recipe tips above to help you get that perfect molten center, fix common mistakes, and make your keto lava cake turn out amazing every time.
- Store: Keep low carb lava cake covered in the fridge for up to 3 days. The center will firm up when cold, so plan to reheat before digging in.
- Reheat: For best results, warm in a 350 degree F oven for about 10 minutes. Or, place the lava cake on a plate, cover with a damp paper towel, and microwave for 30–40 seconds until soft and melty again.
- Freeze: Let the keto chocolate lava cakes cool, then freeze on a baking sheet before wrapping tightly. They’ll keep for up to 3 months, though the center may be a little less molten once reheated.

J
0We’re just starting to eat Keto and this is our go to treat ! Love this
Maya | Wholesome Yum
0Awww, thank you! So glad to hear it’s your go-to.
Kathryn Waterman
0I’m wondering if I can make this ahead and bake later for our Valentine’s Dinner? Can’t wait to try it!
Maya | Wholesome Yum
0Hi Kathryn, I haven’t tried this but I don’t think so because the melted chocolate would set. I suppose it might melt again in the oven but don’t think it would work the same way. Let me know how it goes if you try it, though!
PEGGY HOUSEPIAN
0Is there an option for coconut flour?
Wholesome Yum D
0Hi Peggy, You could try using a teaspoon of coconut flour in place of the tablespoon of almond flour, but I can’t guarantee that it would work. Let me know how it goes if you give it a try.
MonaLisa
0This was so good! I don’t have rameklns so I used silicone muffin molds and made 4 cakes. I unfortunately cooked them a little too long (toothpick came out wet and top looked just done). They were not “lava” inside, but were delicious!
Jenniffer LaCroix
0Hi, I was just wondering if I could use 85% chocolate. I find other brand chocolate bars because I find choczero expensive, especially with all the stuff I make. Thanks.
Maya | Wholesome Yum
0Hi Jenniffer, Yes, any brand of chocolate that fits your macros should work fine.
Gail
0Had a craving for chocolate and this lava cake was delish! Definitely making it again
Pam
0Easy and yummy recipe! I creamed the butter and sugar substitute (half golden Monkfruit and half Erythritol and Monkfruit blend) much longer than 1 min until the batter was a light yellow. The resulting texture was very fine and the center gooey! My husband could not tell it was made with almond flour. This is a winner!
Best keto recipe website!!! I’ve also tried Keto French Almond cake and keto Cloud Bread (Oopsie Bread) recipe. They were a hit with my family. Just made the coconut flour cake and realized that I left out the sour cream unintentionally. I’m praying that the cake will be moist ….
Darelynn Clay
0Since when is 21.1 g carbs considered low carb? Am I missing something here? I’m not on a keto diet, just low carb. Are all of your recipes keto? Thanks
Wholesome Yum D
0Hi Darelynn, There are 4.7g net carbs making this dessert keto friendly.
Ruth
016.4 grams of that is fiber.
Kathleen Bellus
0I’m a bit confused. Is the nutritional info for the whole lava cake or per serving? In one place it states serving size is one cake, and in another it says the cake is two servings. Thanks for your time and clarification!
Wholesome Yum D
0Hi Kathleen, The recipe makes 2 cakes/servings and the nutritional facts are for 1 cake/serving.
Marta E English
0Made this lava cake for yesterday’s dessert!! OMG, it will definitely be one of my favorites!! My husband wanted me to make it again today!! He must have liked it, too!!
Carol
0I’ve made the lava cake recipe twice now, and it keeps getting better each time if that’s possible! So rich and decadent and when topped with your raspberry sauce, oh my!! A real winner plus it’s so easy to make, but your guests will never know it.
William Heller
0Hi. I’ve used most alternative powdered sweeteners, most are incredibly too sweet and leave the cold mouth feel. Does the Monk fruit/Allulose Powdered have these qualities? Thanks. This recipe looks amazing. I usually substitute granular for powdered.
Wholesome Yum D
0Hi William, Besti Blend does not have a cooling effect and measures/ bakes just like real sugar.
Steve
0We made this tonight Keto Chocolate Lava Cake, absolutely delicious and easy to make and even easier to eat, YUM.
Andrea
0I made these for my husband and me the other night for dessert, and they were terrific! The perfect treat!
Carolena
0What size ramekins are you using?
Maya | Wholesome Yum
0Hi Carolena, I use these ramekins.
Melissa
0I’d love to make this but can’t get Choc Zero in Canada. Please let me know the weight amount for the chocolate so I can make this. I’d love to try it!
Wholesome Yum D
0Hi Melissa, This recipe uses about 80g of dark chocolate.
Linda
0THANK YOU!!!!!!!
Bobbi
0I tasted the batter and it was amazing. I really could have just eaten the batter. I overbaked mine a bit, but they are still incredible! I didn’t have the chocolate recommended, so I used Lily’s chips. Since I double the recipe, I used 8 oz. of chips. I will make this again. Thanks!!
Laura
