Ingredients

• 1 cup (112g / 4 oz) blanched almond flour
• ½ cup (42g / 1.48 oz) unsweetened cocoa powder
• ¼ cup (48g / 1.69 oz) Swerve or other granular erythritol sweetener
• 4 large eggs, room temperature
• ½ cup (112g / 4 oz) coconut oil, melted
• ¼ cup (42g / 1.48 oz) sugar-free dark chocolate chunks or chips
• 1 teaspoon (5 ml / 0.2 fl oz) rum extract (or vanilla extract)
• 1 cup (240 ml) water, for the Instant Pot

Instructions

1. Directions
2. Prepare your Instant Pot by pouring 1 cup (240 ml) of water into the inner stainless steel pot. Place the metal trivet inside and set aside.
3. In a large mixing bowl, whisk together the eggs, Swerve sweetener, melted coconut oil, and rum extract until the mixture is light, creamy, and well-combined.
4. Sift the almond flour and cocoa powder directly into the wet . Gently fold them together until just combined, being careful not to overmix. Stir in the dark chocolate chunks.
5. Evenly divide the batter among four 6-ounce ramekins. Cover the top of each ramekin tightly with a piece of aluminum foil to prevent condensation from dripping into the cakes.
6. Carefully place the foil-covered ramekins onto the trivet inside the Instant Pot. Secure the lid, turn the steam release handle to the ‘Sealing’ position, and select the ‘Manual’ or ‘Pressure Cook’ setting. Set the timer for 15 minutes at high pressure.
7. Once the cooking cycle is complete, allow the pressure to release naturally for 15 minutes. Afterward, carefully perform a quick release for any remaining pressure. Using oven mitts, remove the hot ramekins and place them on a wire rack. Let them cool for a few minutes before carefully removing the foil and serving warm.

Pro Tips

• When you add the dry , mix only until they are just incorporated. Overmixing can result in a tougher, denser cake.
• For an extra gooey center, add a large square of your favorite sugar-free chocolate to the middle of each ramekin before cooking. It will melt into a perfect molten core.

FAQ

Q: Can I make these keto lava cakes without an Instant Pot
A: This recipe is specifically developed for the Instant Pot to create the perfect molten center. Baking in a conventional oven would require different timing and has not been tested for these specific instructions.

Q: What can I use instead of Swerve sweetener
A: You can substitute Swerve with another granular erythritol-based sweetener in a 1:1 ratio. Other keto-friendly sweeteners like monk fruit or allulose can also be used, but you may need to adjust the amount to taste.

Q: Why are my lava cakes not gooey in the center
A: A fully cooked center might happen if the cooking time was too long. For a guaranteed molten core, try the pro tip of adding a large square of sugar-free chocolate to the middle of each ramekin before pressure cooking.

Q: Is it necessary to use room temperature eggs
A: Yes, using room temperature eggs is crucial for this recipe. They emulsify better with the melted coconut oil, preventing it from solidifying and ensuring a smooth, uniform batter texture.

Pro Tips

  • Press a large square of sugar-free chocolate into the middle of each ramekin before cooking. It melts into a guaranteed molten core even if the cakes run a minute long.
  • Whisk room-temperature eggs with the melted coconut oil until the mixture looks light and creamy. Cold eggs can make the coconut oil solidify and leave the batter looking curdled.
  • Sift the almond flour and cocoa powder over the wet mixture and fold only until no dry streaks remain. Extra mixing turns these lava cakes cakey and dense instead of fudgy.
  • Cover each ramekin tightly with foil and let the pressure release naturally for 15 minutes before venting. The slow finish keeps the centers soft and molten.
  • These are best served warm, but leftovers keep in the fridge for up to 3 days. Reheat one for 30-45 seconds in the microwave, knowing the center firms up once it cools.

Frequently Asked Questions

Can I make these keto lava cakes without an Instant Pot?

The recipe is built around pressure cooking to get the molten center, and oven timing isn't tested for it. If you experiment in the oven, watch closely since the edges dry out much faster.

What can I use instead of Swerve in the lava cakes?

Any granular erythritol sweetener works in a 1:1 swap, and monk fruit or allulose blends are fine too. Sweetness varies by brand, so adjust to taste.

Why are my lava cakes not gooey in the middle?

They most likely cooked a bit too long. For a molten core every time, tuck a square of sugar-free chocolate into the center of the batter before pressure cooking.

Can I freeze these chocolate lava cakes?

Yes, cooled cakes freeze for up to a month; thaw them in the fridge overnight. Keep in mind the molten center sets once frozen, so reheat gently to soften it again.
