Is Lava Cake Keto?

Regular lava cake recipes are not keto-friendly, as they usually contain high-carb ingredients such as wheat flour, sugar, and chocolate. However, this keto lava cake recipe is a delicious low-carb alternative, with only 3g net carbs per serving.

Made with almond flour and natural sweetener, this lava cake is both delicious and healthy.

Ingredients for Keto Lava Cake

To make my favorite keto lava cake, you’ll need just 7 ingredients. Despite looking so intimidating and complicated to make, these delicious chocolatey treats are so quick and easy!

Here are all the ingredients you’ll need for this super-rich keto lava:

chocolate lava cake ingredients
  • Cocoa Powder – Use the highest quality you can find. It’s used instead of almond flour and helps this cake become super fluffy.
  • Dark chocolate – You can use unsweetened dark chocolate chips too. I used 90% chocolate, but you can also use Lily’s sugar-free chocolate chips.
  • Eggs – use room temperature large eggs to reduce the eggy taste.
  • Heavy cream – for some extra creaminess.
  • Powdered sweetener – I used my favorite monk fruit blend with zero carbs and no aftertaste! Stevia drops are not an option in this recipe.
  • Vanilla extract – Just a little bit for a tint of vanilla flavor.
  • Baking powder – To make it extra fluffy.
  • A pinch of sea salt: To highlight the chocolate flavors

How to Make Keto Lava Cake?

It’s extremely simple to make the best lava cake that is completely sugar-free, flourless, low in carbs, and tastes incredibly delicious. Here’s all you have to do:

Preparing The Ramekins

Preheat the oven to 350°F and grease 3 4 oz ramekins. Look for ramekins that have a non-stick coating to make it easier to remove the cake from the ramekin.

Making The Batter

Combine the dry ingredients (almond flour, cocoa powder, baking powder, and salt) in a medium bowl.

In another bowl, combine the wet ingredients (eggs, erythritol, vanilla extract) with the melted chocolate. You can use an electric mixer and mix until bubbles form.

Combine all the ingredients together, whisking thoroughly until a smooth chocolate batter forms.

Divide the batter among the prepared ramekins and place them in the preheated oven.

Baking The Keto Lava Cake

Bake for about 10-12 minutes or until the keto lava cake looks set, but it’s still jiggly in the middle. Be careful not to overbake, or you’ll lose the gooey lava center.

Once done, remove the ramekins from the oven and let them cool for a few minutes.

To serve, run a knife around the edges of the ramekins to loosen the cakes. Invert them onto a plate and serve with your favorite keto-friendly toppings.

Remember, baking time may vary depending on your oven, so keep an eye on the cakes to avoid overbaking.

With a little practice and the right ingredients, you can enjoy a decadent keto lava cake that satisfies your sweet cravings without compromising your health goals.

 This Chocolate Keto Lava Cake is super rich, chocolaty and tasty. You’ll need only 7 ingredients and 20 minutes for this keto dessert filled with perfectly gooey and creamy chocolate lava.

Pro Tips For Making The Best Lava Cake

To make the best keto lava cake, here are some tips to follow:

  • Use room temperature eggs: This helps to reduce the eggy taste and allows the eggs to mix into the batter completely without overmixing.
  • Don’t overbake the cakes: The center should still be super jiggly when you take them out of the oven. Overbaking will result in a dry, crumbly cake without a gooey lava center.
  • Preheat your oven completely: Make sure your oven is completely preheated before placing the ramekins inside. This way, the cake cooks on the outside while the inside remains super moist.
  • Use high-quality ingredients: Using high-quality ingredients like almond flour, cocoa powder, and sugar-free chocolate chips will ensure a rich, decadent flavor.
  • Experiment with flavors: Try adding different flavors like mint extract, orange zest, or cinnamon to the batter for a unique twist on the classic chocolate lava cake.
  • Serve with keto-friendly toppings: Top your keto lava cake with a generous scoop of keto vanilla ice cream, a dollop of keto whipped cream, or drizzle with keto Nutella for an extra indulgent treat.

Flavor Variations

  • Peanut Butter: add a dollop of natural peanut butter to the center of the cake batter before baking. The peanut butter will melt and create a delicious, creamy lava.
  • Raspberry: Add a spoonful of sugar-free raspberry jam to the center of the cake batter before baking.
  • Salted Caramel: Drizzle a sugar-free caramel sauce over the baked lava cake and top with flaked salt.
  • Mint Chocolate: Add a drop of peppermint extract and sugar-free chocolate chips to the batter.
  • Orange Chocolate: Add some orange zest to the cake batter.

How To Store

  • Fridge – Store covered in the refrigerator for up to 3 days. Reheat in the oven at 350F for 5-7 minutes or until warm.
  • Freezer – Remove the cakes from the ramekins and allow to cool completely. Place them on a baking tray and freeze until solid. Transfer them to a freezer-safe bag and store for up to 3 months. When ready to enjoy, thaw in the fridge overnight and reheat in the oven.

This is the best keto dessert that I have made. My batter came out thicker and I cooked a little longer but it was still delicious. It looked like the picture. Thank you for this wonderful recipe.

This looks soo delicious! Chocolate Lava cake was one of my favs pre-Keto! Your nutritional info says 5g sugars….where is that coming from? Does it mean sugar alcohols from the erythritol? Thanks!

Joanna October 9, 2019 - 7:07 am

It’s naturally occurring sugars in cocoa powder, dark chocolate, and heavy cream.
