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.

- 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!
