🌋 Ingredients for this keto chocolate molten lava skillet cake recipe

  • ¼ cup unsalted butter
  • 3 oz sugar-free chocolate chips
  • 1 large egg at room temperature
  • 1 large egg yolk at room temperature
  • 3 tablespoons powdered erythritol (such as Swerve)
  • ¼ teaspoon sea salt
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon almond flour
  • 1 teaspoon coconut flour

Ingredient substitutions

  • Swap erythritol with another keto-friendly sweetener like monk fruit sweetener or stevia.
  • Use hazelnut flour or sunflower seed flour instead of almond flour for a nut-free option.
  • Substitute coconut flour with double the amount of almond flour.

Additional ingredients

  • Fresh berries: Place a few raspberries or strawberries on top for added color and flavor. Keep an eye on the carb count if you're following a strict keto diet.
  • Whipped cream: Add a dollop of homemade keto-friendly whipped cream for a luxurious touch.
  • Sugar-free caramel sauce: Drizzle a little over the top to elevate your dessert experience. Remember to factor in the carbs if necessary.
  • Chopped nuts: Sprinkle a few toasted pecans or hazelnuts for added texture and depth. Don't go nuts (pun intended) with the quantity, which might affect the keto balance.

Cooking tools required

  • Cast iron skillet (6-inch)

Tools substitute options

Chef's pro tip

For the perfect molten lava center, keep a close eye on the baking time. Begin checking the cake a minute or two before the suggested time is up. The center should be slightly jiggly, while the edges should be set. Remember, it’s better to slightly underbake this keto lava cake than to overdo it.

How to make it healthier

  • Use grass-fed butter for a healthier fat content.
  • Opt for sugar-free chocolate chips with natural sweeteners like stevia or monk fruit.
  • Substitute the erythritol with another keto-friendly sweetener like stevia or allulose.
  • Choose organic eggs for better nutritional quality.

Time-saving tips

  • Measure out and prepare all ingredients before starting the cooking process.
  • Use a kitchen timer to ensure the perfect cooking time and avoid overbaking.

Storage and reheating instructions

Leftover storage

To store any leftovers of your Low Carb Molten Lava Cake, follow these options:

  • Cover the skillet tightly with plastic wrap or aluminum foil.
  • Transfer the remaining cake to an airtight container.

For the best quality, consuming leftovers within 2-3 days is recommended. Store them in the refrigerator to maintain freshness and ensure safety.

Leftover reheating methods and best practices

To reheat your leftover Keto Friendly Chocolate Lava Skillet Cake, try these methods:

  • Oven: Preheat your oven to 300°F. Place the leftover cake in an oven-safe dish and cover it with aluminum foil. Reheat for 5-10 minutes or until you get warm chocolate lava cake.
  • Microwave: Place the leftover cake on a microwave-safe plate and heat for 30-60 seconds or until warmed through. Be cautious not to overheat, as the lava cake can become dry.

Best practices:

  • Always reheat small portions at a time to avoid uneven heating.
  • Monitor the reheating process closely to avoid overcooking and drying out the cake.
  • Allow the cake to cool for a minute or two before enjoying it, as the filling can become very hot.

Frequently asked questions

The ideal doneness is when the top is set, but the middle remains soft and jiggly. Be cautious not to overcook the cake, as it will lose its gooey molten center. Using a kitchen timer can help ensure you achieve the perfect baking time.

Freezing is not recommended for this dessert, as it can affect the texture and quality of the cake. It's best to store leftovers in the refrigerator, tightly covered with plastic wrap or aluminum foil, and consume them within 2-3 days.

While it is possible to use cocoa powder instead of sugar-free chocolate chips, it will require some adjustments to the recipe. For every ounce of sugar-free chocolate chips, you can substitute with 3 tablespoons of unsweetened cocoa powder, 1 tablespoon of a keto-friendly sweetener, and 1 tablespoon of fat (such as butter, coconut oil, or ghee). Remember that this substitution may result in a slightly different flavor and texture, so you may need to experiment to achieve the desired outcome.

    Do you think this would work with any other keto friendly flour? Allergic to almonds.

    Loved it! I split it into 3 portions since my son is type 1 diabetic and my husband it type2. This type of dessert is perfect for all 3 of us, since I'm keto!

    Can this be made without erythritol? I have an extreme reaction to Swerve. 🙁
