Keto lava cake is the ultimate low carb dessert. It’s sweet, rich, fatty, and super indulgent. It makes a great treat for special occasions that will have guests impressed at your baking skills!
Insert the word ‘lava’ anywhere because this cake will be oozing with peanut butter lava once you dig in! It’s a simple molten lava cake to make, but we wanted to go ahead and make a recipe video for you anyway.
The best part of making recipe videos is that we always make two. One for the video itself and one for photography, which meant I had the chance to indulge in this cake twice already!
A “Reeses” Lava Cake Recipe!
This chocolate lava cake is like a massive reeses cup just waiting for you to take a bite. Since you get to dictate how much peanut butter goes in you really can make it exactly like the candy with a 4 to 1 ratio of peanut butter to chocolate.
We first made this keto lava cake without the frozen peanut butter disc, but once we made it and tried it a second time we knew it was vital to allow for maximum peanut butter lava in this recipe.
How to Make A Keto Lava Cake
Ready to make the gooey-est low carb lava cake of your life!? This is by far the best keto recipe out there because it’s molten chocolate cake PACKED with peanut butter.
Ingredients
Our lava cake ingredients are pretty straight forward, but don’t let that stop you from customizing this recipe to make your perfect cake.
To make this recipe you will need, unsweetened cocoa powder, bakers chocolate, peanut butter, butter, heavy whipping cream, an egg, stevia, low carb sweetener, coconut flour, and baking powder. Optionally you can add vanilla extract for extra flavor.
Making a Keto Chocolate Lava Cake
Begin by making your frozen peanut butter disk. In a mixing bowl combine peanut butter and sweetener (if desired). Pour the peanut butter mixture into a parchment paper lined mini springform pan. Freeze until solid.
In a separate bowl combine the butter and bakers chocolate by melting them in the microwave (30 second bursts are best)
Add the heavy cream, egg, and stevia drops to the chocolate butter mixture. Set aside.
Mix together the erythritol, cocoa powder, coconut flour, and baking powder in a separate bowl. Combine the dry and wet ingredients, mixing to get a smooth batter.
Pour half the batter into a greased ramekin or mini springform pan. 4″ springform pans work well for this recipe. Then place your frozen peanut butter disk in the center and top with the rest of your batter. Make sure the peanut butter doesn’t run out into the edges if you decide to not freeze a disk ahead of time.
Bake the gooey lava cake for 13-15 minutes at 400 degrees. The edges should be set, but the center will be jiggly and look like it’s not fully cooked.
Serve right away with some sugar free ice cream. If you used a springform pan you should be able to just move it out onto a plate.
How to Store Keto Chocolate Lava Cakes
This keto friendly gooey chocolate cake is best on the first day. If you’ve tried this recipe then you know the cake batter will continue to cook and then fully set if left to cool and reheat.
If you do want to store leftovers we recommend putting your molten lava cake in an airtight container in the fridge for up to 5 days. When reheating be careful to only cook it just enough to get warm. Anymore and you will probably have peanut butter cake instead of a real lava cake.
What to Serve With This Easy Keto Lava Cake Recipe
Now that we can make keto lava cake i’m sure you’re wondering what you can top this tasty treat with to stay within your low carb diet. There are now a lot of brands who make delicious keto sugar free ice cream that can be used as a lava cake topping.
Some of our favorite keto lava cake toppings are from:
- Enlightened – This is probably top tier sugar free ice cream because they have so many super indulgent flavors you don’t even miss real ice cream.

- Rebel Creamery – Rebel is one of the first keto dessert/ ice cream companies that only makes keto products. It’s available nationwide now in almost every Walmart making keto easy for the masses. And topping keto dessert recipes even easier.
These are probably the most popular varieties and best keto options for ice cream if you are someone looking to indulge without messing up your diet. These are even great options for topping other keto recipes like a mug cake, not just our delicious chocolate lava cake.

Recipe can be quickly added to MyFitnessPal – Search “KetoConnect – Chocolate Peanut Butter Cake”
Ingredients:
- 1 oz Unsweetened Bakers Chocolate
- 2-3 tbsp Peanut Butter
- 2 tbsp Butter
- 1 tbsp Heavy Whipping Cream
- 1 large Egg
- 2 tbsp Low Carb Sugar Substitute
- 5-7 liquid Liquid Stevia
- 1 tbsp Unsweetened Cocoa Powder
- 2 tsp Coconut flour
- 1/4 tsp Baking powder
Instructions:
- Optional Make Ahead: In our video we made a frozen peanut butter disc to optimize peanut butter to chocolate ratio and it’s also perfectly melty when you cut into the cake. You can also choose to dollop in 2-3 tbsp of peanut butter right into the middle. **To increase sweetness you may want to add 5 drops of stevia to the peanut butter.
- Combine bakers chocolate and butter and melt in a microwave safe bowl in bursts of 30 seconds.
- Add cream, egg and stevia drops to the chocolate and butter mixture. Set aside.
- Combine all dry ingredients: erythritol, coco powder, coconut flour and baking powder in a separate bowl.
- Mix the dry ingredients into the wet ingredients until you get a smooth uniform thick batter.
- Pour half the batter into your greased ramekin or springform pan. We use a 4″ springform pan for this.
- Place the peanut butter right in the center without allowing it to run to the edges.
- Pour the second half over the peanut butter.
- Bake in a 400 degree oven for 13-15 minutes.
- You’ll know it’s done when the edges have firmed and the center is still a little jiggly/not fully cooked seeming.
- Serve immediately and enjoy!

Margaret Limgenco says
Can I use cooking cream instead of heavy whipping cream?
Cindi says
Gave this a try tonight. Taste fantastic, I did get it too dry though. The PB did melt..
Will try again with more cream if needed..
Sharon says
Can you exchange coconut milk for heavy cream if u r lactose intolerant
Keto Connect (Shannon) says
You sure can (or coconut cream, as long as it’s the canned version) 🙂
Vanessa says
I made this adding Sukrin’s Fiberfin for half of the coconut flour which reduced the carb count to 0.5 for the whole cake! Fiberfin is 10 g fiber per tbsp….heaven!
Leila says
Omg, this looks amazing! Can’t wait to try this!
Is it possible to completely omit the liquid stevia and just use granulated stevia as the sweetener?
Thanks!
Keto Connect (Shannon) says
Hey Leila! You could totally sub that! It should bake up just fine 🙂
Debra says
I made this and put in a cast iron 4″ skillet with 3 cupcake muffin papers. My peanut butter was ground and did not melt, but nonetheless, they came out perfect. Will make this again, maybe next time with peanut butter that melts. They were mini cakes with fun center.
Jeff says
Would Coconut Cream work as a substitute for heavy cream? Any other suggestions? I’m experimenting with no dairy.
Matt Gaedke says
Ya, that should work.
Vrushali Dharmadhikari says
I made these in the form of small muffins….and OMG! peanut butter in every muffin!!! LOVED it…Thank you Matt and Megha ….you guys make amazing stuff! …Plus it’s guilt free …. Lot’s of love!
Ivette says
This dessert was amazing! Totally satisfied my dessert craving!
ANDREA says
could this recipe be doubled for a larger pan?
Matt Gaedke says
Yes it could. You’d have to play with the cooking time in order to get the lava center though!
Sylvia says
You guys are great!! Please let me know what temperature the oven has to be on for the lava cakes you made. Thanks for all your hard work!!!!
Matt Gaedke says
400 degrees
Nives says
Did you subtract the fiber from carbs for net carbs? Trying to get real net carb
Matt Gaedke says
Our net carbs count is with fiber and erythritol subtracted. We also include the total carb value.
Amanda says
I’m so excited to try this next week and adding the necessary ingredients in my Amazon cart…. Have you tried this recipe or any recipe with monkfruit sweetener? I’ve have it just taste better?
Matt Gaedke says
Monk fruit will work great, especially in place of the liquid stevia.
marche' says
Monkfruit sweetener -in place of Stevia?- My monkfruit has/is erythritol!!
Megha Barot says
The liquid monkfruit doesn’t have erythritol in it. You could also try allulose, which is less commonly used but can be found online and is similar to sugar in a 1 to 1 ratio.
Claudia Hochhalter says
Omg! I just made this ! It’s delicious! Thank you guys for the awesome recipes !
Andrew says
Could I substitute the stevia for more erythritol?
Matt Gaedke says
Yes you can!
N says
I dont have erythritol can I just add some more stivia drops?
Matt Gaedke says
That should work. Add a bit of extra flour if necessary to get the batter thicker.
Matt says
This is a test
Nichole Nudo says
Made this last night. Made the recipe 4 times bigger as we had non keto friends over who said ohhh this is really good it actually taste sweet like sugar haha!
We didn’t get the peanut butter frozen so it did come out the edges but still worked great!
Megha Barot says
That’s one big lava cake!! And peanut butter oozing out the sides is never a bad thing hehe. Thanks for sharing!
Monica says
Would everything get multiplied by 4? For long should it bake?
Joyce Holthaus says
When you made this 4X bigger did you use a bigger pan? How long did you bake it for?
Thank you!!
Megan says
I’m allergic to coconut. How much almond flour would you use instead?
Matt Gaedke says
It’s really tough to substitute those 2. You could try about 6-8 tbsp almond flour.
Alison says
Really want to make this, but my boyfriend has some stomach sensitivity to coconut flour. I’d like to do half coconut and half almond, unless you have another flour to suggest.
What do you think about the measurements for half and half?
Thank!!
Amanda says
I made this tonight and it was soooo good! I will be making this probably weekly! Haha! whats better than pb and chocolate cake!!! Thank you for sharing!!
Vanesa says
Oh my gosh! I made this with dutch cocoa and mixed in sugar free nutella to the peanut butter and it was heaven!
Susan says
How did I not know there is sugar-free Nutella until now? Must find!
Xavier says
Yes please, WHERE can we find sugar free Nutella? Made my own keto style, but ehh….
Megha Barot says
We are working on a recipe!
Lynne says
You can buy it from this site. Sometimes you can get it on amazon.
