Introduction

The first time you bite into this cake, you'll know you just found your favorite low carb chocolate dessert. It's so rich that you won't believe it fits in your keto diet!

With only 5 grams of net carbs per cake, you can afford to treat yourself to this without any guilt.

Ingredient Tips and Substitutions

The entire recipe is at the bottom of this post. First, I want to share a few tips about these ingredients, including any substitutions you can make.

This recipe has all the basic keto-baking ingredients like vanilla extract and baking powder.

I used powdered sweetener to get the perfect texture in the cake. Use a powdered sweetener, don't try to use a granular or liquid one instead, it won't turn out the same.

I also used almond flour. I recommend using almond flour, not almond meal. Almond meal has bits of the almond skin in it and it will make the cake taste grainy.

You can use salted butter instead of unsalted. If you do this, just cut back on how much salt you use in the recipe.

Quick Tips

You can cook these even quicker if you use the microwave. Be careful when you do this so that you don't overcook the center of the cakes.

Garnish the cakes with sugar-free whipped cream. You can also add a few raspberries on top. If you add a side of fruit, be careful that you aren't adding too many carbs to it.

How To Make Keto Molten Lava Cake

If you love to see a visual step-by-step, here are a few photos to walk you through the process. For the complete details about how to make this recipe, please scroll down to the printable recipe card.

This has to be one of the easiest dessert recipes on my site. All you do is mix all the ingredients together in a mixing bowl until it's creamy.

Then, pour the batter into ramekins. Bake them until the outside is firm but there is still a little jiggle in the middle.

recipe steps

You can certainly eat them right out of the ramekins! I know it's going to be tough to wait for them to cool down. That aroma is going to fill your kitchen and make you drool.

If you wait, then you can put the small cake onto a plate and then dust it with some substitute confectioner's sugar.

This is a beautiful way to present and enjoy this dessert! When it sits on the plate, you can see the melted chocolate pour out of the cake like a volcano.

What To Serve With Keto Chocolate Cake

This has such a rich flavor that you might not have much room for anything else. It is such a beautiful dessert to serve after dinner with a hot cup of coffee or tea.

You can also serve a scoop of homemade almond milk ice cream on the side. Use the gooey chocolate as a topping for your ice cream, it's delicious!

If ice cream is too rich, you can also serve this with a lighter option such as low-carb pumpkin mousse. It's light and airy and will pair perfectly with the cake.

Frequently Asked Questions About Molten Lava Cake

Before we get to the recipe, I want to answer some questions about it first.

How Many Carbs Are In This Keto Molten Lava Cake Recipe?

There are only 5 grams of net carbs in each chocolate cake. This amount will change if you add anything to it or make your cakes larger or smaller than mine.

I figured out the net carbs by taking the total amount of carbs and subtracting the amount of fiber.

Can you substitute coconut flour for almond flour?

No, you cannot substitute coconut flour for almond flour without having to change the recipe significantly. Coconut flour absorbs a lot more liquid, so you'll have to add more wet ingredients to this cake to keep it from being too dry.

Are Molten Lava Cakes Safe To Eat?

Yes, they are completely safe to eat. I know this sounds like such a strange question, but it's been asked pretty frequently because you aren't baking the cake completely through.

Eggs only need to be cooked to at least 160 degrees to be safe to eat. This is baked at 350 degrees for 15 minutes, which is plenty long enough to make the cake safe to eat.

Can I Freeze Molten Lava Cake?

Yes, you can freeze these molten lava cakes. Let them cool completely and then wrap them up individually in plastic wrap before you put them in a freezer-safe bag or container.

When you are ready to enjoy one, let it set in the refrigerator overnight to thaw out. Then, heat it in the microwave until it is just heated through - about a minute or so.

These cakes will stay fresh in the freezer for up to 3 months.

Indulge In Molten Lava Cake

If you need a dessert recipe to treat yourself with while you are on the keto diet, this is it! There are just a few easy ingredients, it doesn't take long to make, and it literally oozes chocolate. You can't beat it.

Plus, it won't kick you out of ketosis. Don't deny yourself the enjoyment of a rich chocolate cake while on keto, just make sure that what you eat is low in carbs - like this one.

Ingredients

  • 1 tablespoon Almond flour
  • 2 tablespoon Unsalted Butter melted
  • 2 large eggs at room temperature
  • ¼ cup Unsweetened cocoa powder
  • 3 tablespoon Swerve confectioners sugar substitute
  • ½ teaspoon Baking powder
  • ½ teaspoon Vanilla extract

Instructions

  • Preheat the oven to 350°F degrees.
  • In a mixing bowl, combine the ingredients together and beat on high until smooth and creamy.
  • Pour the batter evenly into two well greased 6-ounce ramekins.
  • Bake for 12-15 minutes, or until the edges of the cake are firm, but the center still has a little jiggle to it.
  • Let cool for several minutes, and then turn over onto a plate to serve.
  • Garnish with sugar free whipped cream if desired.

Notes

You can cook the cakes individually in the microwave, but you'll need to be careful not to overcook the centers.
If overcooked, the center won't be molten so be sure to check every few minutes so the cakes can be removed from the oven before the centers are set.

    Hi Lisa.

    I’m extremely allergic to all forms of anything ALMONDS, anything COCONUT and anything AVOCADOS (ie: flours, milks, oils, sprays). My nutritionist wants me to use Fairlife Milk for cooking because it has such low carbs.
    Do you have any suggestions for substitutions in recipes for flour, spray release like Pam and oils?
    Thank you!

      You could try sunflower seed flour as it's a one-for-one sub for almond flour. Oat fiber is a good sub for coconut flour but it's not a one-for-one. As for oil, you should be able to use a seed based oil even though they aren't recommended for keto.

    This was just ok. What brand did you use for the Cocoa powder. I used Hershey and my husband said It tastes like cheap baker’s chocolate. How can I get this to tastes more rich. Maybe it was the brand I used. I might try the chocolate cup recipe.

      I use Ghiradelli cocoa as I find it tastes better than Hershey's.

      Sorry about that! You do need to be careful not to overcook and keto desserts tend to be on the less sweet side. You can always add in a few drops of liquid sweetener if needed. I don't recommend adding more erythritol based granular sweetener as it can crystallize if too much is added.

    Would like to make for my Valentine Sunday. Can I make ahead of time? Is it OK to sit at room temp for a few hours, wondering if the chocolate will set up.

      It's best to make this just before serving. If making ahead, I'd recommend taking out of the oven early so you can place in a warm oven before serving and not cook the center. Preparing the batter ahead may also work.

    I don't have ramekins. Do you thing I could use wide mugs if making in the microwave?

    Reply
    • Lisa MarcAurele

      Wide mug is fine. However, the cake will cook fast on high power so you may want to try reducing the power setting on the microwave so you don't overcook.

        The molten part results from uncooked batter inside the cake. You could fully cook the cake then fill it with a filling using a pastry bag.

      You can double and place in two ramekins or one larger baking dish. You may just need to adjust cooking time.

    Does the size of the ramekin matter? I’m seeing 4 oz and 6 oz on Amazon.

      It does impact baking time. I use two 6-ounce ramekins. If you use another size, it will impact baking time.

      I used 6-ounce ramekins. For the microwave, you need to be very careful not to overcook. I'd recommend cooking on 60% power and checking every 30 seconds or so.
