Is Lava Cake Keto?

Traditional lava cakes are usually not keto-friendly because they contain wheat flour, refined sugar, and high-carb chocolate—all of which can spike your carbs and kick you out of ketosis.

But the good news? This keto lava cake is a low-carb version that lets you enjoy all the rich, gooey goodness without the sugar or carbs. Made with simple ingredients like almond flour, sugar-free chocolate, and a keto sweetener, each serving has just 3g net carbs.

It’s a perfect way to enjoy your favorite dessert while staying on track with your low carb or keto lifestyle.

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:

• 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.

Pro Tips for Making the Best Keto Lava Cake

Follow these simple tips to make your keto chocolate lava cake turn out rich, gooey, and full of flavor every time:

• Use room temperature eggs – This helps blend the batter smoothly and keeps the texture soft without that “eggy” taste.
• Don’t overbake – To keep that signature molten center, bake just until the edges are set but the center is still slightly jiggly. Overbaking will dry it out.
• Preheat the oven fully – A hot oven ensures the outside bakes properly while the center stays soft and gooey.
• Choose high-quality ingredients – Good almond flour, unsweetened cocoa powder, and sugar-free chocolate make a huge difference in flavor and texture.
• Add your own twist – Mix in flavors like mint extract, orange zest, or a pinch of cinnamon to make it your own.
• Top it off – Serve warm with a scoop of keto vanilla ice cream, a swirl of whipped cream, or drizzle with sugar-free chocolate sauce or keto Nutella for an extra special touch.

Flavor Variations for Keto Lava Cake

Switch things up with these fun and tasty ideas. Each version adds a unique twist to your favorite low-carb dessert:

• 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.
